BASIC OPERATION MODULATION
The water heaters covered in this manual have a helical coil
shaped heat exchanger that is submerged in the storage tank.
The water heater's Main Burner is a radial design burner, it
is mounted on the top and fires downward through t.he heat
exchanger. This is a forced draft burner; hot burning gases are
forced through the heat exchanger under pressure and exit
through the exhaust/vent connection located at the bottom of the
water heater. See Figure I and Figure 2.

The water heaters covered by this manual are capable of
modulating their firing rate. The CCB monitors the water
temperature in the tank and regulates the firing rate to achieve
the target temperature setpoint. The firing rate is dictated by
the hot water draw, proximity to the tank temperature setpoint,
and various other temperature limitations. Periodically, when the
heater is in modulation mode, the CCB will increase the blower
speed for a short period of time to clear out any condensation
that has accumulated in the heat exchanger then decreases
the blower speed back to the modulating firing rate required to
maintain the desired tank temperature setpoint. This ramping up
and down of the blower speed is considered normal operation of
the water heater.

The control system energizes the spark ignition control with 120
VAC during the ignition cycle. The spark ignition control then
sends a high -voltage current to the spark igniter which in turn
ignites the main burner air/gas mixture.
Flame Sensor
The control system also monitors the flame sensor to confirm
a flame is present at the Main Burner. If a flame is not verified
during the ignition trial period (3-5 seconds) the control system
will immediately de -energize the 24 Volt Gas Valve. See the
Sequence Of Operation Flow Chart on page 58.

COMPONENTS (All Models)
IMPORTANT. The Enable/Disable switch listed in this manual is
NOT an "on/off" switch and does not disconnect 120 volt power
to the CCB and other heater components.
1. Water Heater's Enable/Disable Switch. When in the "Disabled"
position the switch removes electrical power from the gas
valve and blower so that water heating is disabled. The
display, CCB, and other electrical components will still be
energized and the display will read "Water Heating Disabled".
2. Powered anode rods, The water heaters covered in this
manual are equipped with powered (non sacrificial) anode
rods. The BTH 120 has one powered anode, all other models
will have two. Protective current is fed by the control system
to the titanium electrodes at the end of each anode rod. This
current flows through the water to the conductive surfaces
inside the storage tank which diminishes the corrosive effect
(rusting) of water when it comes in contact with steel.
3. Central Control Board (CCB) enclosure. This enclosure
houses the control system's main circuit board, power supply
board, power transformer, and configuration key. The CCB
regulates water temperature and controls all water heater
functions, see Control System Operation on page 45.

rise in pressure. This switch is used to insure the Combustion
Blower is operating properly at blower start-up. The control
system monitors this switch and will disable heating operation
if its contacts are closed before the Combustion Blower is
energized. See Sequence Of Operation on page 57.
14. Temperature -Pressure Relief Valve. See Temperature -
Pressure Relief Valve on page 15.
15. Upper Temperature Probe, 1 of 2 temperature probes. The
water heater's control system monitors this probe to detect
water temperature in the upper portion of the storage tank.
The Upper Temperature Probe also houses the ECO (energy
cut out) switch. This is a non adjustable high temperature
limit switch. The ECO switch contacts are normally closed
and will open on a temperature rise. See High Temperature
Limit Control (ECO) on page 44.

LOCATING THE WATER HEATER
Carefully choose a location for the new water heater. The
placement is a very important consideration for the safety of the
occupants in the building and for the most economical use of the
water heater.
Property Damage Hazard
* All water heaters eventually leak.
* Do not install without adequate drainage
Whether replacing an existing water heater or installing the water
heater in a new location observe the following critical points:
1 . The water heater must be located indoors.
2. The water heater must not be located in an area where it will
be subject to freezing temperatures.
3. Locate the water heater so it is protected and not subject to
physical damage by a moving vehicle.
4. Locate the water heater on a level surface.
5. Locate the water heater near a f loordrain. The water heater should
be located in an area where leakage of the tank or connections
will not result in damage to the area adjacent to the water heater
or to lower floors of the structure. When such locations cannot be
avoided, it is recommended that a metal drain pan, adequately
drained, be installed under the water heater.
6. Locate the water heater dose to the point of major hotwater usage.
7. Locate the water heater close to a 120 VAC power supply.
See Power Supply on page 13 for requirements.
8. Locate the water heater where an adequate supply of fresh
air for combustion and ventilation can be obtained. See Air
Requirements on page 17.
9. Locate the water heater where the vent and intake air piping,
when installed, will remain within the maximum equivalent
lengths allowed. See Venting Requirements on page 22.
10. Do not locate the water heater where noise (such as
the Combustion Blower) during normal operation will be
objectionable in adjacent areas.
11. Do not locate the water heater where the subsequent
installation of the vent (exhaust) or intake air terminations
would be objectionable due to noise at the termination(s).
This includes locations close to or across from windows and
doors. See Venting Installation on page 21.
Fire or Exo1osion Hazard
• Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
• Avoid all ignition sources if you smell gas.
• Do not expose water heater controls to excessive gas
pressure.
• Use only the gas shown on the water heater rating label.
• Maintain required clearances to combustibles.
• Keep ignition sources away from faucets after extended
periods of non-use.
%�Ili '0 A
Read instruction manual before
installing, using or servicing
water heater.
There is a risk in using fuel burning appliances such as gas
water heaters in rooms, garages or other areas where gasoline,
other flammable liquids or engine driven equipment or vehicles
are stored, operated or repaired. Flammable vapors are heavy
and travel along the floor and may be ignited by the water
heater's igniter or Main Burner flames causing fire or explosion.
Flammable items, pressurized containers or any other potential
fire hazardous articles must never be placed on or adjacent to
the water heater.
CLEARANCE TO COMBUSTIBLE MATERIALS
The water heaters covered in this manual are approved for
installation on combustible flooring. The clearance to combustible
and non combustible construction materials is 0 inches on the
back and sides of the water heater. These water heaters are also
approved for installation in an alcove.
When the water heater is installed directly on carpeting, the water
heater shall be installed on a metal or wood panel extending
beyond the full width and depth of the water heater by at least
3 in (76.2 mm) in any direction or, if the water heater is installed
in an alcove or closet, the entire floor shall be covered by the
panel. The panel must be strong enough to carry the weight of
the heater when full of water.
NOTE: Adequate clearance for servicing should be maintained
on all installations. See Service Clearance below.

possible above the water heater and near the exhaust elbow for
this reason. See Figure 8 on page 16.
INTAKE AIR AND VENT PIPE CLEARANCES
The minimum clearance from combustible materials for the vent
(exhaust) and intake air piping shall be 0 inches. Vent or intake
air piping passing through a combustible wall or ceiling must be
a continuous run (no joints),
EXTENDED VENT TERMINATIONS -
The water heaters covered by this manual can be installed using
-3 inch pipe for the intake air and/or vent piping up to a maximum
of 50 equivalent feet (15.2 m). The intake air and/or vent piping
can be extended up to 120 equivalent feet (36.5 m) by installing
4 inch pipe. See the Venting Requirements on page 22.
The water heater ships from the factory with two (2) 3 inch
terminations that are 45' PVC elbows with a debris screen
installed. When 4 inch intake air or vent pipe is installed, factory
supplied 4 inch terminations must be used.
Contact your local distributor or call the parts department phone
number listed on the back cover of this manual to order 4 inch
termination(s).
OPTIONAL CONCENTRIC & LOW PROFILE TERMINATIONS
The water heaters covered in this manual can be installed in
a Direct Vent configuration using optional concentric or Low
Profile terminations. See Concentric Termination Installation
on page 30 and Low Profile Vent Termination Installation on
page 34.

Where hard water conditions exist, water softening or the
threshold type of water treatment is recommended. This will
protect the dishwashers, coffee. urns, water heaters, water
piping and other equipment. See Maintenance on page 63 for
sediment and lime scale removal procedures.
CIRCULATION PUMPS
A circulating pump is used when a system requires a circulating
loop or there is a storage tank used in conjunction with the water
heater. The tank is provided with a 3/4" NPT recirculation loop
return connection. See the Water Piping Diagrams beginning on
page 69 for installation location of circulating pumps.
See Circulation Pump Wiring Diagrams on page 68 for
electrical hookup information. Install in accordance with the
current edition of the National Electrical Code, NFPA 70 or the
Canadian Electrical Code, CSA C22.1.
Stainless steel circulating pumps are recommended for use with
commercial water heaters.
Some circulating pumps are manufactured with sealed bearings
and do not require further lubrication. Some circulating pumps
must be periodically oiled. Refer to the pump manufacturer's
instructions for lubrication requirements.
INSULATION BLANKETS
Insulation blankets are available to the general public for
external use on gas water heaters but are not necessary
with these products. The purpose of an insulation blanket is
to reduce the standby heat loss encountered with storage
tank heaters. The water heaters covered by this manual meet
or exceed the Energy Policy Act standards with respect to
insulation and standby heat loss requirements, making an
insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this
heater, you should follow these instructions. See the Features
and Components section of this manual for identification
of components mentioned below. Failure to follow these
instructions can restrict the air flow required for proper
12
combustion, potentially resulting in fire, asphyxiation, serious - DO NOT cover the instruction manual. Keep it on the side of
personal injury or death. the water heater or nearby for future reference.
• DO NOT apply insulation to the top of the water heater, as
this will interfere with safe operation of the blower assembly,
• DO NOT cover the control system LCD on top of the water
heater.
• DO NOT cover the Temperature -Pressure Relief Valve.
GAS SUPPLY SYSTEMS
Low pressure building gas supply systems are defined as
those systems that cannot under any circumstances exceed
14" W.C. (1/2 PSI Gauge). These systems do not require
pressure regulation. Measurements should be taken to insure
that gas pressures are stable and fall within the requirements
stated on the water heater rating plate. Readings should be
taken with all gas burning equipment off (static pressure)
and with all gas burning equipment running at maximum rate
(dynamic pressure). The gas supply pressure must be stable
within 1.5" W.C. from static to dynamic pressure to provide
good performance. Pressure drops that exceed 1.5" W.C. may
cause rough starting, noisy combustion or nuisance outages.
Increases or spikes in static pressure during off cycles may
cause failure to ignite or in severe cases damage to appliance
gas valves. If your low pressure system does NOT meet these
requirements, the installer is responsible for the corrections.
High Pressure building supply systems use pressures that
exceed 14" W.C. (1/2 PSI Gauge). These systems must use
field supplied regulators to lower the gas pressure to less than
14" WC. (1/2 PSI Gauge). Water heaters require gas regulators
that are properly sized for the water heater input and deliver
the rating plate specified pressures. Gas supply systems where
pressure exceeds 5 PSI often require multiple regulators to
achieve desired pressures, Systems in excess of 5 PSI building
pressure should be designed by gas delivery professionals
for best performance. Water heaters connected to gas supply
systems that exceed 14" W.C. (1/2 PSI Gauge) at any time
must be equipped with a gas supply regulator.
All models require a minimum gas supply pressure of 4.4" WC.
for natural gas and 8.5" W.C. for propane gas. The minimum
supply pressure is measured while gas is flowing (dynamic
pressure). The supply pressure should never fall below 4.4"
W.C. for natural gas and 8.5" WC. for propane gas. The supply
pressure should be measured with all gas fired appliances
connected to the common main firing at full capacity. If the supply
pressure drops more than 1.5" W.C. as gas begins to flow to
the water heater then the supply gas system including the gas
line and/or the gas regulator may be restricted or undersized.
See Supply Gas Regulator section and Gas Piping section of
this manual. The gas valve on all models has a maximum gas
supply pressure limit of 14" WC. The maximum supply pressure
is measured while gas is not flowing (static pressure).
SUPPLY GAS REGULATOR
The maximum allowable gas supply pressure for this water
heater is 14.0 inches W.C. (3.49 kPa) for natural and propane
gas. Install a positive lock -up gas pressure regulator in the gas
supply line if inlet gas pressure can exceed these pressures at
any time.
• DO obtain new warning and instruction labels from the
manufacturer for placement on the blanket directly over the
existing labels.
• DO inspect the insulation blanket frequently to make certain it
does not sag, thereby obstructing combustion air flow.
If a positive lock -up regulator is required follow these instructions
1 . Positive lock -up gas pressure regulators must be rated
at or above the input Btu/hr rating of the water heater
they supply.
2. Supply gas regulators shall have inlet and outlet connections
not less than the minimum supply gas line size for the water
heater they supply. See Table 11, page 40.
3. Positive lock -up gas pressure regulator(s) should be installed
no closer than 3 feet (1 meter) and no farther than 8 feet (2.4
meters) from the water heater's inlet gas connection.
4. After installing the positive lock -up gas pressure regulator(s)
an initial nominal supply pressure setting of 7.0" W.C.
while the water heater is operating is recommended and
will generally provide good water heater operation. Some
addition adjustment maybe required later to maintain a
steady gas supply pressure.
5. When installing multiple water heaters in the same gas
supply system it is recommended that individual positive
lock -up gas pressure regulators be installed at each unit
from the supply gas connection on the water heater.
POWER SUPPLY
The water heaters covered in this manual require a 120 VAC,
10 (single phase), 60Hz, 15 amp power supply and must also
be electrically grounded in accordance with local codes or, in
the absence of local codes, with the National Electrical Code,
ANSI/NFPA 70 or the Canadian Electrical Code, CSA C22. 1.
DEDICATED POWER WIRING AND BREAKERS
Dedicated power supply wires, ground wiring and dedicated
circuit breakers often prevent electrical line noise and are
required when installing the water heater.
POWER FLUCTUATIONS AND ELECTRICAL NOISE
The water heater's control system requires a source of
stable clean electricity for proper operation. Connecting the
water heater to a branch circuit that is subject to fluctuations
in voltage level or electrical line noise such as EMI (electro
magnetic interference) or RFl (radio frequency interference)
may cause erratic control system operation and malfunction.
A high quality power supply filter/suppressor such as the
Kleen Line model SELF/T-1 0 Series SC-L or equivalent must
be installed if the above conditions exist. Call the technical
support phone number listed on the back cover of this manual
for more information.
NOTE: Malfunctions caused by the power supply and costs to
install power supply filters are not covered under the limited
warranty.

MIXING VALVES
Water temperature over 125'F (52*C)
can cause severe burns instantly
resulting in severe injury or death.
Children, the elderly and the
physically or mentally disabled are at
highest risk for scald injury.
Feel water before bathing or
�_-HOT
showering.
Temperature limiting devices such as
B BURN
URN
mixing valves must be installed
when required by codes and to
ensure safe temperatures at fixtures.
Water heated to a temperature which will satisfy clothes washing,
dish washing, and other sanitizing needs can scald and cause
permanent injury upon contact. Short repeated heating cycles
caused by small hot water uses can cause temperatures at the
point of use to exceed the water heater's temperature setting by
up to 20'F (11*C).
Some people are more likely to be permanently injured by
hot water than others. These include the elderly, children, the
infirm and the physically/mentally disabled. Table 5 shows the
approximate time -to -burn relationship for normal adult skin.
If anyone using hot water provided by the water heater being
installed fits into one of these groups or if there is a local code
or state law requiring a certain water temperature at the point of
use, then special precautions must be taken.
In addition to using the lowest possible temperature setting that
satisfies the demand of the application a Mixing Valve should be
installed at the water heater (see Figure 7) or at the hot water
taps to further reduce system water temperature.
Mixing valves are available at plumbing supply stores. Consult
a Qualified Installer or Service Agency. Follow mixing valve
manufacturer's instructions for installation of the valves.

DISHWASHING MACHINES
All dishwashing machines meeting the National Sanitation
Foundation requirements are designed to operate with water
flow pressures between 15 and 25 pounds per square inch (103
kPa and 173 kPa). Flow pressures above 25 pounds per square
inch (173 kPa), or below 15 pounds per square inch (103 kPa),
will result in improperly sanitized dishes. Where pressures are
high, a water pressure reducing or flow regulating control valve
should be used in the 180'F (82*C) line to the dishwashing
machine and should be adjusted to deliver water pressure
between these limits.

The National Sanitation Foundation also recommends circulation
of 180'F (82'C) water. Where this is done, the circulation should
be very gentle so that it does not cause any unnecessary
turbulence inside the water heater. The circulation should be just
enough to provide 180'F (82*C) water at the point of take -off to
the dishwashing machine.
Adjust flow by throtding a full port ball valve installed in the
circulating line on the outlet side of the pump. Never throttle flow
on the suction side of a pump. See the Water Piping Diagrams
beginning on page 69.
NOTE: To comply with NSF Standard 5 installation requirements
the bottom of the water heater must be sealed to the floor with a
silicone based sealant or elevated 6 inches above the floor.
CLOSED WATER SYSTEMS
Water supply systems may, because of code requirements
or such conditions as high line pressure, among others, have
installed devices such as pressure reducing valves, check
valves, and back flow preventers. Devices such as these cause
the water system to be a closed system.
THERMAL EXPANSION
As water is heated, it expands (thermal expansion). In a
closed system the volume of water will grow when it is heated.
As the volume of water grows there will be a corresponding
increase in water pressure due to thermal expansion. Thermal
expansion can cause premature tank failure (leakage). This
type of failure is not covered under the limited warranty.
axpansion can also cause intermittent Temperature -
Pressure Relief Valve operation: water discharged from the
valve due to excessive pressure build up. This condition is
not covered under the limited warranty. The Temperature -
Pressure Relief Valve is not intended for the constant relief
of thermal expansion.
A properly sized thermal expansion tank must be installed on
all closed systems to control the harmful effects of thermal
expansion. Contact a local plumbing service agency to have a
thermal expansion tank installed.
See Water Line Connections on page 43 and the Water Piping
Diagrams beginning on page 69.

TEMPERATURE -PRESSURE RELIEF VALVE
Explosion Hazard
• Temperature -Pressure Relief Valve
must comply with ANSI Z21.22-
CSA 4.4 and ASME code.
• Properly sized temperature -
pressure relief valve must be
installed in opening provided.
• Can result in overheating and
excessive tank pressure.
• Can cause serious injury or death,
This water heater is provided with a properly rated/sized and
certified combination Temperature -Pressure Relief Valve (T&P
valve) by the manufacturer. The valve is certified by a nationally
recognized testing laboratory that maintains periodic inspection
of production of listed equipment of materials as meeting the
requirements for Relief Valves for Hot Water Supply Systems,
ANSI Z21.22 - CSA4.4, and the code requirements ofASME.
If replaced, the new T&P valve must meet the requirements
of local codes, but not less than a combination Temperature -
Pressure Relief Valve rated/sized and certified as indicated in
the above paragraph. The new valve must be marked with a
maximum set pressure not to exceed the marked hydrostatic
working pressure of the water heater (150 psi = 1,035 kPa) and
a discharge capacity not less than the water heater Btu/hr or kW
input rate as shown on the water heater's model rating label.
NOTE: In addition to the factory installed Temperature -Pressure
Relief Valve on the water heater, each remote storage tank that
may be installed and piped to a water heating appliance must also
have its own properly sized, rated and approved Temperature -
Pressure Relief Valve installed. Call the toll free technical
support phone number listed on the back cover of this manual
for technical assistance in sizing a Temperature -Pressure Relief
Valve for remote storage tanks.
For safe operation of the water heater, the Temperature -Pressure
Relief Valve must not be removed from its designated opening
nor plugged. The Temperature -Pressure Relief Valve must be
installed directly into the fitting of thewater heaterdesigned forthe
relief valve. Install discharge piping so that any discharge will exit
the pipe within 6 inches (15.2 cm) above an adequate floor drain,
or external to the building. In cold climates it is recommended
that it be terminated at an adequate drain inside the building. Be
certain that no contact is made with any live electrical part. The
discharge opening must not be blocked or reduced in size under
any circumstances. Excessive length, over 30 feet (9.14 m), or
use of more than four elbows can cause restriction and reduce
the discharge capacity of the valve.
No valve or other obstruction is to be placed between the
Tempe ratu re- Pressure Relief Valve and the tank. Do not connect
discharge piping directly to the drain unless a 6" (15.2 cm)
air gap is provided. To prevent bodily injury, hazard to life, or
property damage, the relief valve must be allowed to discharge
water in adequate quantities should circumstances demand. If
the discharge pipe is not connected to a drain or other suitable
means, the water flow may cause property damage.
Water Damage Hazard
Temp6rature-Pressure Relief Valve discharge
pipe must terminate at adequate drain.
T&P Valve Discharge Pipe Requirements:
• Shall not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
• Shall not be plugged or blocked.
• Shall not be exposed to freezing temperatures,
• Shall be of material listed for hot water distribution.
• Shall be installed so as to allow complete drainage of both the
Tempe rature-Pressu re Relief Valve and the discharge pipe.
• Must terminate a maximum of six inches above a floor drain
or external to the building. In cold climates, it is recommended
that the discharge pipe be terminated at an adequate drain
inside the building.
• Shall not have any valve or other obstruction between the
relief valve and the drain.

discharge outlet.
The Temperature -Pressure Relief Valve must be manually
operated at least twice a year. Caution should be taken to
ensure that (1) no one is in front of or around the outlet of the
Temperature -Pressure Relief Valve discharge line, and (2) the
water manually discharged will not cause any bodily injury or
property damage because the water may be extremely hot. If
after manually operating the valve, it fails to completely reset
and continues to release water, immediately close the cold water
inlet to the water heater, follow the draining instructions in this
manual, and replace the Temperature -Pressure Relief Valve with
a properly rated/sized new one.
NOTE: The purpose of a Temperature -Pressure Relief Valve is
to prevent excessive temperatures and pressures in the storage
tank. The T&P valve is not intended for the constant relief of
thermal expansion. A properly sized thermal expansion tank must
be installed on all closed systems to control thermal expansion,
see Closed Water Systems and Thermal Expansion on page 14.

CONDENSATE DRAIN
The water heaters covered in this manual are condensing
appliances and require a building drain to be located in close
proximity to allow the condensate to drain safely.
Condensate drains from the water heater at the exhaust elbow
located at the bottom. The field installed condensate drain line
must not be elevated above the condensate drain connection
on the condensate trap, see Figure 8. If the condensate does
not drain properly it will build up in the exhaust (vent) elbow.
This will restrict the flow of flue gases and cause the Blocked
Exhaust pressure switch to open its contacts. The control system
monitors all pressure switches, if the Blocked Exhaust Switch
contacts are open the control system will lock out and disable
heating operation. The "Blocked Exhaust" Fault message will
be displayed on the control system's LCD, see Fault And Alert
Conditions beginning on page 60.
The Condensate Cleanout Cap must be on and tight when unit
is in operation.
NOTE: If the "Blocked Exhaust " Fault message is ever displayed
on the control system LCD, check the condensate drain first and
ensure it is not blocked.

CONDENSATE PH LEVEL
The condensate drains from the water heater's covered in
this manual have PH levels between 4.3 and 5.0. Install a
commercially available neutralizing kit if required by local codes.
NOTE: Lower PH levels are acidic. Do not connect a metal drain
line, such as copper, to the water heater for this reason. See
Condensate Drain Installation on page 39.
COMBUSTIBLE MATERIAL STORAGE
Fire or Explosion Hazard
• Do not store or use gasoline or other flammable vapors and
liquids in the vicinity of this or any other appliance.
• Avoid all ignition sources if you smell gas.
• Do not expose water heater controls to excessive gas
pressure.
• Use only the gas shown on the water heater rating label.
• Maintain required clearances to combustibles.
• Keep ignition sources away from faucets after extended
periods of non-use.
Read instruction manual before
installing, using or servicing
water heater.
Keep water heater area clear and free of combustible materials,
gasoline and other flammable vapors and liquids.
CONTAMINATEDAIR
Breathing Hazard - Carbon Monoxide Gas
Install water heater in accordance with
the Instruction Manual and NFPA 54 or
CAN/CSA-B149.1.
To avoid injury, combustion and ventilation
air must be taken from outdoors,
Do not place chemical vapor emitting
products near water heater.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
Corrosion of the flue ways and vent system may occur if air for
combustion contains certain chemical vapors. Such corrosion
may result in failure and risk of asphyxiation.
Combustion air that is contaminated can greatly diminish the
life span of the water heater and water heater components such
as igniters and burners. Propellants of aerosol sprays, beauty
shop supplies, water softener chemicals and chemicals used
in dry cleaning processes that are present in the combustion,
ventilation or ambient air can cause such damage.
Do not store products of this sort near the water heater. Air which
is brought in contact with the water heater should not contain any
of these chemicals. If necessary, uncontaminated air should be
obtained from remote or outdoor sources. The limited warranty is
voided when failure of water heater is dueto a corrosive atmosphere.
(See limited warranty for complete terms and conditions).
If the water heater will be used in beauty shops, barber shops,
cleaning establishments, or self-service laundries with dry
cleaning equipment, it is imperative that the water heater(s) be
installed in a Direct Vent configuration so that all air for combustion
is derived directly from the outdoor atmosphere through a sealed
intake air pipe. See Venting Installation on page 21.

AIR REQUIREMENTS
Breathing Hazard - Carbon Monoxide Gas
Install water heater in accordance with
the Instruction Manual and N FPA 54 or
CAN/CSA-13149.1.
To avoid injury, combustion and ventilation
air must be taken from outdoors.
Do not place chemical vapor emitting
products near water heater.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual. I
For safe operation an adequate supply of fresh uncontaminated
air for combustion and ventilation must be provided.
An in sufficient supply of air can cause recirculation of
combustion products resulting in contamination that may be
hazardous to life. Such a condition often will result in a yellow,
luminous burner flame, causing sooting of the combustion
chamber, burners and flue tubes and creates a risk of
asphyxiation.
Do not install the water heater in a confined space unless an
adequate supply of air for combustion and ventilation is brought
in to that space Using the methods described in the Confined
Space section that follows.
Never obstruct the flow of ventilation air, If you have any doubts
or questions at all, call your gas supplier. Failure to provide the
proper amount of combustion air can result in a fire or explosion
and cause property damage, serious bodily injury or death.
UNCONFINED SPACE
An Unconfined Space is one whose volume IS NOT LESS THAN
50 cubic feet per 1,000 Btu/hr (4.8 cubic meters per kW) of the
total input rating of all appliances installed in the space. Rooms
communicating directly with the space, in which the appliances
are installed, through openings not furnished with doors, are
considered a part of the unconfined space.
Makeup air requirements for the operation of exhaust fans,
kitchen ventilation systems, clothes dryers and fireplaces shall
also be considered in determining the adequacy of a space to
provide combustion, ventilation and dilution air.
UNUSUALLY TIGHT CONSTRUCTION
In unconfined spaces in buildings, infiltration may be adequate
to provide air for combustion, ventilation and dilution of flue
gases. However, in buildings of unusually tight construction (for
example, weather stripping, heavily insulated, caulked, vapor
barrier, etc.) additional air must be provided using the methods
described in the Confined Space section that follows.
CONFINEDSPACE
A Confined Space is one whose volume IS LESS THAN 50 cubic
feet per 1,000 Btu/hr (4.8 cm per kW) of the total input rating of
all appliances installed in the space.
Openings must be installed to provide fresh air for combustion,
ventilation and dilution in confined spaces. The required size for
the openings is dependent on the method used to provide fresh
air to the confined space AND the total Btu/hr input rating of all
appliances installed in the space.
DIRECT VENT APPLIANCES
Appliances installed in a Direct Vent configuration that derive all
air for combustion from the outdoor atmosphere through sealed
intake air piping are not factored in the total appliance input Btu/
hr calculations used to determine the size of openings providing
fresh air into confined spaces.
EXHAUSTFANS
Where exhaust fans are installed, additional air shall be provided
to replace the exhausted air. When an exhaust fan is installed
in the same space with a water heater, sufficient openings to
provide fresh air must be provided that accommodate the
requirements for all appliances in the room and the exhaust fan.
Undersized openings Will cause air to be drawn into the room
through the water heater's vent system causing poor combustion.
Sooting, serious damage to the water heater and the risk of fire
or explosion may result. It can also create a risk of asphyxiation.
LOUVERS AND GRILLES
The free areas of the fresh air openings in the instructions that
follow do not take in to account the presence of louvers, grilles or
screens in the openings.
The required size of openings for combustion, ventilation and
dilution air shall be based on the "net free area" of each opening.
Where the free area through a design of louver or grille or screen
is known, it shall be used in calculating the size of opening
required to provide the free area specified. Where the louver and
grille design and free area are not known, it shall be assumed
that wood louvers will have 25% free area and metal louvers and
grilles will have 75% free area. Non motorized louvers and grilles
shall be fixed in the open position.

Breathing Hazard - Carbon Monoxide Gas
• Install vent system in accordance with codes,
• Do not operate water heater if exposed to flooding or
waterdamage
• Special consideration must be taken with installations
above 10,000 feet (3,048 m) refer to high altitude
section of this manual.
Do not operate 9 soot buildup.
• Do not obstruct water heater air intake with insulating
jacket or blanket.
• Do not place chemical vapor emitting products near
water heater.
• Gas and carbon monoxide detectors are available.
• Never operate the heater unless it is vented to the
outdoors and has adequate air supply to avoid risks
of improper operation, fire, explosion or asphyxiation.
• Analyze the entire vent system to make sure that
condensate will not become trapped in a section of
vent pipe and therefore reduce the open cross
sectional area of the vent.
Breathing carbon monoxide can cause brain damage or death.
Always read and understand the instruction manual.
Never operate the water heater unless it is vented to the outdoors.
The instructions in this section of the manual must be followed
to avoid choked combustion or recirculation of flue gases. Such
conditions cause sooting of the combustion chamber, burners
and flue tubes and creates a risk of asphyxiation.
GENERAL VENTING INFORMATION
The water heaters covered in this manual are operationally
equivalent to Category IV appliances and may be installed in
either a Power Vent or Direct Vent configuration.
APPROVED MATERIALS
Approved vent and intake air pipe materials that may be used in
the United States:
PVC Schedule 40 (ASTM D 2241 / CSA 13181.2, ASTM D
1785 / CSA 13137.3
CPVC Schedule 40 (ASTM F-411 / GSA 13137.6)
• Polypropylene
• AI-294C Stainless Steel
Approved vent and intake air pipe materials that must be used
in Canada:
• ULC S636 PVC / CPVC
• ULC S636 Polypropylene
• AL29-4C Stainless Steel
CATEGORY IV APPLIANCE
Category IV appliances operate with a positive vent (exhaust)
static pressure and with vent gas temperatures low.enough to
produce condensate in the vent piping.
POWER VENT CONFIGURATION
Power Vent configurations derive all combustion air from the
room where they are installed and discharge all flue gases to
the outdoor atmosphere through a sealed vent (exhaust) pipe.
Power vent configurations have one vent pipe connected to the
water heater which can be terminated in a vertical or horizontal
arrangement. See Figure 42 and Figure 43 on page 35.
DIRECT VENT CONFIGURATION
Direct Vent configurations derive all combustion air directly from
the outdoor atmosphere through a sealed intake air pipe and
discharge all flue gases to the outdoor atmosphere through a
sealed vent (exhaust) pipe. Direct Vent configurations have two
pipes connected to the water heater, one vent pipe and one
intake air pipe. Direct Vent configurations can be terminated in
one of seven different arrangements. See Figure 44 on page
35 through Figure 50 on page 36.
GENERAL VENTING INSTRUCTIONS
These instructions must be followed on all installations.
1 . DO NOT install the water heater in a PowerVent configuration
unless there is adequate supply of fresh air, see Air
Requirements on page 17. If the installation space does
not provide an adequate supply of fresh air the water heater
must be installed in a Direct Vent configuration.
2. If the water heater is to be installed in a beauty shop,
barber shop, cleaning establishment, a laundry with dry
cleaning equipment or any space with contaminated air it is
imperative that the water heater(s) be installed in a Direct
Vent configuration so that all air for combustion is derived
from the outdoor atmosphere.
3. The vent and intake air piping must terminate outdoors.
4. The minimum clearance from combustible materials for the
vent (exhaust) and intake air piping shall be 0 inches. Vent
piping passing through a combustible wall or ceiling must be
a continuous run (no joints).
5. The water heater must be protected from freezing downdrafts
during shutdown periods.
6. The vent (exhaust) pipe must not be combined or connected
to any other appliance's vent system or chimney.
7. The intake air pipe must not be combined or connected to
any other appliance's intake air piping.
8, Locate the water heater where the vent (exhaust) and intake
air piping will remain within the maximum equivalent lengths
allowed. See Venting Requirements on page 22.
9. Do not install the vent or intake air piping in a manner that will
allow water to be trapped in the piping.
10. Vent pipes must be pitched a minimum of a 1/4 inch per foot
back to the water heater (to allow drainage of condensate).
11. Do not anchor the vent or intake air pipe directly to framed
walls, floors or ceilings unless rubber isolation pipe hangers
are used to prevent vibration noise from being transmitted.
12. Use only approved vent/intake air pipe sizes and materials.
See Venting Requirements on page 22.
13. Use only factory supplied vent and intake air or concentric
terminations. See the Venting Requirements on page 22.
14. Do not locate the vent (exhaust) or intake air terminations
where they would be objectionable due to noise at the
termination(s). This includes locations close to or across from
windows and doors.
15. Direct venting into dead air spaces such as alleys, atriums,
and inside comers can cause recirculation of flue gases.
Recirculation of flue gases will cause sooting, premature
failure of the heat exchanger and icing of the combustion
air intake during severe cold weather. To prevent the
recirculation of flue gases, maintain as much distance as
possible between the intake air and vent terminations.
16. Do not locate the vent termination over a public area where
condensate or vapor can cause a nuisance or ice hazard.
17. Ensure the screens in the factory supplied terminations are
securely installed to prevent blockage in the vent system.
21
18. Stress levels in pipe/fiftings can be significantly increased by
improper installation. If rigid pipe clamps are used to hold
the pipe in place, or if the pipe cannot move freely through a
wall penetration, the pipe may be stressed, or high thermal
stresses may be formed when the pipe heats up and expands.
Install accordingly to minimize such stresses.
19, Ensure the intake air connection Tee fitting is oriented properly,
see page 22 for instructions.
20. Carefully read the Venting Requirements on page 22 and then
proceed to the Venting Installation Sequence on page 23.
INTAKE AIR CONNECTION
The water heaters covered in this manual are factory equipped
with a unique Combustion Blower and intake air connection
Tee fitting. The Tee is a 3" x 3" x 1/2" fitting. The intake air
connection Tee fitting has a hose barb installed in the 1/2 inch
branch to connect the Blocked Intake Air switch sensing tube,
see Figure 14.

Ensure the hose barb installed in the Tee fitting IS NOT facing
down towards the ground (180* -6 o'clock position) before venting
installation begins. The barb fitting must be angled between 90*
and no more than 130* as shown in Figure 15. If the barb fitting
is facing down, residual condensate that occasionally forms in
the intake air pipe can drain into the Blocked Intake Air switch
through the attached sensing tube and damage the switch. This
condition can also lead to Blocked Intake Air fault conditions and
associated control system lock outs.

INTAKE AIR TEE FITTING
Figure 15
The intake air Tee fitting is factory installed with the 1/2 inch
branch and hose barb angled to the right at approximately 130'
when viewed from the end, see Figure 15. The Tee fitting's
1/2 inch branch and hose barb must not be angled any lower
(towards the ground) than this factory specification. Angling
higher, up to a 90' position, will not adversely affect operation
and is acceptable.
INSPECTIADJUST INTAKE AIR TEE FITTING
Inspect the angle of the Tee fitting's 1/2 inch branch and hose
barb while viewing fromthe end of the Tee, see Figure 16, If the
angle of the Tee fitting 1/2 inch branch and hose barb �s lower
than shown, adjustment will be necessary. To adjust the intake
air Tee fitting angle follow the steps listed below.
Adjustment Procedure:
21. Ensure the water heater is turned off at the on/off switch on
the front of the water heater.
22. Disconnect the Blocked Intake Air switch sensing tube, see
Figure 3 on page 8 for location.
23. Loosen the large hose clamp on the Fernco coupling that
connects the intake air connection pipe to the Combustion

SIDEWALL TERMINATION INSTALLATION
12. Determine the location for the termination(s).
13. If installing only vent (exhaust) piping in a Power Vent
configuration through a sidewall; ensure that all exterior
sidewall clearance requirements for the termination, shown
in Figure 51 on page 37, are being maintained. These
clearances and those cited by local and national codes must
be maintained.
14. If installing both the intake air and the vent piping in a
Direct Vent configuration through a sidewall; ensure
that all exterior sidewall clearance requirements for the
terminations, shown in Figure 52 on page 38, for the
vent and the intake air termination are being maintained.
These clearances and those cited by local and national
codes must be maintained.
15. If installing both an intake air and vent termination in a
Direct Vent configuration through a sidewall there must
be a minimum of 24 inches (61 cm) separation, measured
on vertical center line, between the intake air and vent
terminations, see Figure 25.
NOTE: In colder climates this separation should be increased
to at least 48 inches (122 cm) between the intake air and
vent termination or any other appliance vent that discharges
moisture -laden air such as clothes dryers. This will reduce
possibility of frost over from side winds blowing exhaust
vapors to the intake air termination and is recommended for
Canadian installations.
16. If installing both intake air and vent terminations in a Direct
Vent configuration through a sidewall the intake air and
vent terminations must be installed at the same elevation
measured on horizontal center line - see Figure 25.

17. When the intake air and/or vent piping from multiple water
heaters will terminate at the same location through a
sidewall, the vent terminations can be grouped together
in close proximity - 0 inches/touching. The intake air
terminations can also be grouped together in close proximity
- 0 inches/touching.
18. Cut a 4 inch (10 cm) diameter hole for 3 inch pipe or 5 inch
(13 cm) diameter hole for 4 inch pipe where the pipe(s) will
pass through the wall.
NOTE: Beware of concealed wiring and piping when cutting
through the wall.
19. Cut a length(s) of pipe being installed 3.5 inches (8.9 cm)
to 9.5 inches (24.1 cm) longer than the wall thickness at the
opening. See Figure 26.
NOTE: Vent Termination — exhaust gases of this water
heater are less than 140*F. In cold climates water vapor in
the exhaust gases will condense into a cloud of vapor where
the vent exits the building. This vapor can gradually discolor
exterior building surfaces. The vent termination should be
located where this vapor cloud and potential discoloration
are not a concern. Extending the exposed vent piping up to
a maximum of 6 inches (15.2 cm) from the wall helps vapor
from being trapped along a building's face. To avoid this
problem, the vent can also be terminated vertically through
the roof, see Vertical Termination Installation on page 25.
20. Cement the intake air and/or vent termination to the section(s)
of pipe cut to length in the above Step.
21. Slide the included metal wall plate(s) over the pipe(s) to stop
against the intake air and/or vent termination, Place some
silicone caulking (field supplied) on the back of the wall
plate(s) to secure it to the wall.
22. Working from outside, slide the pipe and termination(s)
assembled in the above steps through the wall. Ensure the
termination(s) is pointed down towards the ground. See

24. Press the wall plate flush against the outside wall.
25. Working from the inside apply enough silicone caulking on
the back of the interior wall plate(s) to hold it in place and
slide the wall plate over the installed pipe(s).
26. Install a coupling to the end of the pipe(s) inside the building.
Before the silicone caulking has time to completely set go
outside the building and ensure the termination(s) is still
pointing down towards the ground. See Figure 26.
However, the distance between the closest vent and intake 27
air terminations must be a minimum of 24 inches (61 cm).
In colder climates this separation should be increased to at
least 48 inches (122 cm). See Figure 25.

POLYPROPYLENE INSTALLATIONS
The water heater has been approved to be installed with
Polypropylene vent material as shown in Tables 7 and 8.
The approved application of single wall, non -flexible, non -
concentric Polypropylene vent material is offered by two
specific manufacturers (Centrotherm ECO Systems and
DuraVent Polypropylene. These listed products must be
installed by following the vent manufacturer's instructions.
Refer to Table 6 on Page 23 to determine the maximum pipe
length and number of elbows that can be used.
Insulation should not be used on Polypropylene venting
materials. The use of insulation will cause increased vent wall
temperatures, which could result in vent pipe failure.
Use only the adapters and vent system listed in Tables below.
DO NOT mix vent systems of different types or manufacturers.
Failure to comply could result in severe personal injury, death,
or substantial property damage.
Installations must comply with applicable national, state,
and local codes. For Canadian installation, Polypropylene
vent must be listed as a ULC-S636 approved system. If
Polypropylene vent is not required by. your local code, you
may use either PVC or CPVC pipes for your water heater that
allows non-metallic venting material installations.
TABLE 7
Polypropylene vent systems do not use cement to connect
the pipe and elbow sections but use a push together gasket
seal method. Do not attempt to connect Polypropylene with
sealant cement. All vent connections MUST be secured by
the vent manufacturer's joint connector. The installer must
use a specific vent starter adapter at the flue connection. The
adapter is supplied by the vent manufacturer to adapt to its
vent system.
In orderto be in full compliance with UL 1738 or ULC-S636 and
to meet the requirements of the water heater manufacturer,
you must use the metal joint connector rings, available from
the Polypropylene vent manufacturer, to stiffen the joints of
3" and 4" diameter pipes.

CONCENTRIC TERMINATION INSTALLATION
1 . Concentric terminations must be ordered separately. BTH
120 - 250 models must use the 4 inch concentric termination;
Part Number: 9006328005. Contact your local distributor or
call the parts department phone number on the back cover of
this manual to order concentric terminations.
2. Determine the location for the termination.
NOTE: Roof termination is preferred since it is less susceptible
to damage, has reduced chances to intake contaminants.and
vent vapors are less visible.
3. When installing a concentric termination vertically through the
roof; ensure that all exterior vertical clearance requirements
for the concentric termination, shown in Figure 29 on page
31 are being maintained. These clearances and those
cited by local and national codes must be maintained.
4. When installing a concentric termination vertically through a
flat roof, the termination's vent cap must be a minimum of 10
feet (3 m) away from any parapet, vertical wall or structure as
shown in Figure 27.
CONCENTRIC TERMINATION(S)

Installation on page 25.
5. When installing a concentric termination through a sidewall;
ensure that all exterior sidewall clearance requirements for
the termination, shown in Figure 52 on page 38, are being
maintained. These clearances and those cited by local and
national codes must be maintained.
6. When installing multiple concentric terminations vertically
through a roof or horizontally through a sidewall ensure the
required clearances between terminations and groupings of
multiple terminations are maintained. See pages 32 and
33 for more information.
7. Cut a 5 inch (13 cm) diameter hole for the 4 inch concentric
termination where the termination will pass through the wall or roof.
NOTE: Beware of concealed wiring and piping when cutting
through the wall or roof.
& When installing multiple concentric terminations vertically
through the roof in the same location the termination caps
for all concentric terminations must be at the same height
measured from ground. See Multiple Concentric Termination
Arrangements on page 33.
9. Determine if the concentric termination will need to be
shortened to accommodate required clearances or to ensure
all vent caps are at the same height when installing multiple
terminations vertically through the roof in the same location.
See Figure 28 on page 31 for the minimum lengths allowed
for the 4 inch concentric termination.
Use only SDR-26 pipe to extend the 4 inch concentric

MULTIPLE CONCENTRIC TERMINATION CLEARANCES Four Concentric Terminations
When installing multiple concentric terminations vertically through
a roof or horizontally through a sidewall ensure the required
clearances (separation) between terminations are maintained.
Ensure multiple terminations are arranged or grouped as
required.
NOTE: These clearances must be maintained to prevent the
recirculation of vent (exhaust) gases to the intake air. Clearances
are measured between the edges of the concentric termination
caps.
When installing multiple concentric terminations through a roof
or through a sidewall the clearances shown in Figure 31 must
be maintained.
See Multiple Concentric Termination Arrangements on page 33.
Close Proximity & Standard Clearance
1 . The clearance between multiple termination caps must be 0
inches (touching) to a maximum of 2 inches (5 cm), dimension
A - Figure 31, when installing concentric terminations in close
proximity. See Figure 36 on page 33.
2. The clearance between multiple termination caps must be
increased to a minimum of 24 inches (61 cm), dimension B -

LOW PROFILE VENT INSTALLATION
This water heater is certified for sidewall direct venting with IPEX
System 636 Low Profile Vent Kit. Follow instructions below for
proper installations.
All termination kits must be located and installed in accordance
with loci building code and CSA B149.1 Natural Gas and Propane
Installation Code.
1. Once the proper location has been determined, cut 2 holes in
the wall large enough to accomodate the pipe. See the Chart
at bottom of this page for pipe diameters and distance between
hole centers.
2. Slide both the intake and exhaust pipes through the holes.
Solvent cement both pipes to the base of the vent termination
kit, follow the solvent cementing procedures outlined in the
IPEX System 636 Installation Guide, which is available on the
web www.ipexinc.com.
3. To fasten the Base to the wall, use the supplied screws and
anchors. A 3/16" (5mm) hole, 1-3/16" (30mm) deep, will need
to be drilled for the anchors. Locate the anchor hole using the
base as a template.
4. Screw the Cap to the Base using the supplied screws.
5. Once the vent termination and pipes are secured, the wall
penetrations will need to be sealed from the interior using a
PVC -compatible sealant material.
6, All vent pipes and air inlets must terminate at the same height to
avoid possibility of severe personal injury, death, or substantial
property damage.
7. Operate heater through 1 heat cycle to ensure combustion -air and
vent pipes are properly connected to concentric vent termination.

CONDENSATE DRAIN INSTALLATION
Installation must conform with these instructions and local
building codes.
Field supplied materials required for installation include:
Approved PVC cement and PVC primer.
1/2 inch PVC pipe - minimum length to equal the distance
between the water heater and a suitable building drain.
1/2 inch PVC fittings (elbows, couplings, and adapters)
necessary to install a condensate drain line between the
Exhaust/Condensate Elbow Assembly and a suitable
building drain.
Floor mounted standoffs to brace the drain line.
INSTALLATION NOTES
1 . The condensate drains from the water heater's covered by
this instruction have PH levels between 4.3 and 5.0. Install
a commercially available neutralizing kit if required by local
codes. Lower PH levels are acidic. Do not connect a metal
condensate drain line, such as copper pipe, to the water
heater for this reason.
2. The field installed condensate drain line must not be less
than 1/2 inch PVC in size.
3. DO NOT remove, modify or alter the factory condensate trap.
INSTALLATION INSTRUCTIONS
1 . Ensure the water heater's on/off switch is in the "off position.
2. Install a 112 inch PVC condensate drain line between
condensate drain connection on the Exhaust/Condensate Elbow
and a suitable building drain, see Figure 53.
3. Terminate the condensate drain piping with an elbow above
the drain. Ensure that any discharge will exit the condensate
drain line no more than 6 inches (15.2 cm) above a suitable
building drain, or external to the building, see Figure 53.
NOTE: In cold climates it is recommended the condensate
drain be terminated at a suitable drain inside the building.
4. Ensure the condensate drain line is not elevated above the
condensate drain connection on the Exhaust/Condensate
Elbow, see Figure 53.
5. Brace the condensate drain line with floor mounted standoffs
every three feet.

SUPPLY GAS LINE INSTALLATION
Contact your local gas utility company to ensure that adequate
gas service is available and to review applicable installation
codes for your area.
Be sure that the gas meter has sufficient capacity to supply the
rated gas input of the water heater as well as the requirements
of all other gas fired equipment supplied by the meter. If the
gas meter is undersized, the gas company will have to install a
properly sized gas meter.
00
A
Fire and Explosion Hazard
• Do not use water heater with any gas
other than the gas shown on the rating
label.
• Excessive gas pressure to gas valve can
cause serious injury or death.
• Turn off gas lines during installation.
* Contact a qualified installer or service
agency for installation and service.
Make sure gas supplied is same type listed on the water heater's
rating label.
The water heaters covered in this manual are not intended for
operation at higher than 14.0" W. C. (2.62 kPa) for natural gas and
14.0" W. C. (3.49 kPa) for propane gas supply pressure, see Table
3 on page 11. The water heaters covered in this manual require
supply gas regulators to maintain required supply gas pressure.
Exposure to higher gas supply pressure may cause damage to the
gas controls which could result in fire or explosion. If overpressure
has occurred such as through improper testing of gas lines or
malfunction of the supply system the water heater's gas valve
must be checked for safe operation by a Qualified Service Agency.
Ensure supply regulator vent lines and the safety vent valves are
protected against blockage. These are components of the gas
supply system, not the water heater. Vent blockage may occur
during ice storms.
It is important to guard against gas valve fouling from
contaminants in the gas ways. Such fouling may cause improper
operation, fire or explosion. If copper supply lines are used they
must be internally tinned and certified for gas service.

Ensure all gas pipe is clean on the inside before installation. To
trap any dirt or foreign material in the gas supply line a sediment
trap must be installed as shown in Figure 54. The sediment trap
must be readily accessible and not subject to freezing conditions.
Install in accordance with the recommendations of the local gas
utility company.
GAS LINE SIZING
Depending on the developed equivalent length and/or the number
of appliances connected to a common main, the size of supply gas
lines may have to be increased.
Size the supply/main gas line(s) in accordance with Table 11
or Table 12. The values given in Table 11 and Table 12 are for
straight lengths of iron pipe at 0.5" W C. (125 Pa) pressure drop,
which is considered normal for low pressure systems. Note that
fittings such as elbows and tees will add to the pipe pressure drop.
Schedule 40 Steel or Wrought Iron Pipe is the preferred material
for the gas line of this water heater. It is imperative to follow the
sizing recommendations in the latest version of the National Fuel
Gas Code if Corrugated Stainless Steel Tubing (CSST) is used
as the gas line for this water heater.

WATER LINE CONNECTIONS
The water piping installation must conform to these instructions
and to all local and national code authority having jurisdiction.
Good practice requires that all heavy piping be supported.
Read and observe all requirements in the following sections
before installation of the water piping begins:
1 . Mixing Valves on page 14.
2. Dishwashing Machines on page 14.
3. Temperature -Pressure Relief Valve on page 15.
4. Closed Systems and Thermal Expansion on page 14.
5. For multiple water heater installations see Water Piping
Diagrams beginning on page 69.
WATER PIPING DIAGRAMS
This manual provides detailed water piping diagrams for typical
methods of application for the water heaters, see Water Piping
Diagrams beginning 69.
The water heater may be installed by itself, or with a separate
storage tank. When used with a separate storage tank, the
circulation may be either by gravity or by means of a circulating
pump. When a circulating pump is used, it is important to note
that the flow rate should be slow so that there will be a minimum
of turbulence inside the water heater storage tank.
Adjust flow by throttling a full port ball valve installed in the
circulating line on the outlet side of the pump. Never throttle flow
on the suction side of a pump. See the Water Piping Diagrams
beginning on page 69.
NOTE: In addition to the factory installed Temperature -Pressure
Relief Valve J&P valve) on the water heater, each remote
storage tank that may be installed and piped to a water heating
appliance must also have its own properly sized, rated and
approved Temperature -Pressure Relief Valve installed.
Call the toll free technical support phone number listed on the
back cover of this manual for further assistance in sizing a T&P
valve for remote storage tanks.
THERMOMETERS (NOT SUPPLIED)
Thermometers are installed in the water piping system as a
means of detecting the temperature of the hot water supply
at critical points in the system. Field supplied thermometers
should be obtained and installed. See Water Piping Diagrams
on page 69.
WATER (POTABLE) HEATING AND SPACE HEATING
1 . All water piping components connected to the water heater
that are for space heating applications shall be suitable for
use with potable water.
1 Toxic chemicals, such as those used for boiler treatment,
must NEVER be introduced into this system.
3. The water heaters covered in this manual may never be
connected to any existing heating system or component(s)
previously used with non -potable water heating appliance.
4. When the system requires water for space heating that
exceed safe temperatures at domestic water fixtures a mixing
valve must be installed, see Mixing Valves on page 14.
5. These water heaters cannot be used in space heating
applications only.

HIGH TEMPERATURE LIMIT CONTROL (ECO) TABLE `13
This water heater is equipped with an ECO (energy cut out) non
adjustable high temperature limit switch. The ECO is a normally
closed switch that opens (activates) on a rise in temperature.
The ECO is located inside the Upper Temperature Probe (two
red wires), see pages 8 and 9 for location, The ECO switch
contacts will open when the water temperature reaches
approximately 202*F (94*C) and close at approximately
140-F (49-C).
If the ECO activates (contacts open) due to abnormally high
water temperatures in the storage tank the control system will
immediately de -energize the 24 Volt Gas Valve and end the
current heating cycle. The control system will "lock out" disabling
further heating operabon. The control system will display the
"Energy Cut Out (EGO)" Fault message on the LCD screen.
It is important that a Qualified Service Agent be contacted to
determine the reason for the ECO activation before resetting the
ECO. Once the reason has been determined and corrected the
ECO can be reset as follows:
Should the ECO activate, the water temperature must drop below
140'F (49'C) before the control system can be reset. Once the
water temperature has cooled below this point the power supply
to the water heater must be turned off and on again to reset the
control system.
THERMOSTAT CONTROL

injury and/or death. Table 13 shows the approximate time -to -
burn relationship for normal adult skin.
The temperature at which injury occurs varies with the person's
age and duration of exposure. The slower response time of
children, the elderly or disabled persons increases the hazards
to them. If anyone using hot water provided by the water heater
being installed fits into one of these groups or if there is a local
code or state law requiring a certain water temperature at the
point of use, then special precautions must be taken.
In addition to using the lowest possible temperature setting that
satisfies the demand of the application a mixing valve can be
installed at the water heater (see Figure 7 on page 14) or at
the hot water taps to further reduce system water temperature.
Never allow small children to use a hot water tap or draw their own
bath water. Never leave a child or disabled person unattended in
a bathtub or shower.
The water heater should be located in an area where the general
public does not have access to set temperatures.
Setting the Operating Set Point at 120*F (49'C) will reduce
the risk of scalds. Some States require settings at specific
lower temperatures.

(U.S. Government Memorandum, C.P.S.C., Peter L.Armstrong, Sept. 15,1978)
The water heaters covered in this manual are equipped with an
electronic control system to regulate water temperature inside
the storage tank. The control system senses temperature from
two factory installed temperature probes, one installed in the top
of the storage tank and one installed near the bottom, See Top
Views on page 8 and Figure 4 on page 9 for location.
The "Operating Set Point"is adjusted to regulate water temperature
inside the storage tank. This is an adjustable user setting in
the control system's "Temperatures Menu." This and all control
system menus are accessed through the UIM (user interface
module) located on the front of the water heater, see Figure 57.
The Operating Set Point is adjustable from 90'F (42'C) to 180* F
(82'C). The factory setting is 120*F (49*C). See Operating Set
Point And Differential Adjustment on page 48 for instructions
on how to adjust the Operating Set Point and other user settings.
Set the Operating Set Point at the lowest setting which produces
an acceptable hot water supply. This will always provide the most
energy efficient operation.
MODULATION
The water heaters covered by this manual are capable of
modulating their firing rate. The CC13 monitors the water
temperature in the tank and regulates the firing rate to achieve
the target temperature setpoint. The firing rate is dictated by
the hot water draw, proximity to the tank temperature setpoint.
and various other temperature limitations. Periodically, when the
heater is in modulation mode, the CCB will increase the blower
speed for a short period of time to dear out any condensation
that has accumulated in the heat exchanger then decreases
the blower speed back to the modulating firing rate required to
maintain the desired tank temperature setpoint. This ramping up
and down of the blower speed is considered normal operation of
the water heater.
HIGH TEMPERATURE APPLICATIONS
Higher operating temperatures cause more wear on all water
heaters and will decrease the life span of the water heater.
Consider installing a small booster water heater for high
temperature applications, such as commercial dishwashers, to
raise the outlet temperature from the larger primary water heater
to the desired point of use temperature.
Contact your local distributor or call the technical support phone
number listed on the back cover of this manual for further

OVERVIEW
The water heaters covered in this manual are equipped with an
electronic control system that regulates water temperature inside
the storage tank. Heating cycles and ignition are managed by the
control system. The ECO (energy cut out), flame sensor, pressure
switches and temperature probes are monitored by the control
system. The Combustion Blower, Spark Ignition Control, 24 Volt
Gas Valve and anode rods are all powered by the control system.
The main components of the control system are a UIM (user
interface module) and a CCB (central control board). The UIM
is located on the top front side of the water heater. The CCB 'is
mounted on top of the water heater inside a protective enclosure.
See Features And Components on page 7 for location of

Operating Set Point And Differential Adjustment
The Operating Set Point is adjustable from 90*F (42*C) to 180*F (82*C), The factory setting is 120'F (49'C). The Differential is
adjustable from 2' to 20*. The factory setting is 8*. These user settings are accessed from the Temperatures menu. The following
instructions will explain how to adjust these settings and navigate the control system menus.
When the water temperature sensed by the control system from the two (upper and lower) Temperature Probes reaches the Operating
Set Point the control system will end the heating cycle. A heating cycle will be activated again when the sensed water temperature
drops below the Operating Set Point minus the Differential setting.
NOTE: Lower Differential settings may cause excessive heating cycles (short -cycling) which can cause premature failure of heater
components. Set the Differential at the highest setting which produces an acceptable hot water supply. Set the Operating Set Point
to the lowest setting which produces an acceptable hot water supply for most efficient use.

NOTE: These settings should only be used if the hot water
supply temperature varies greatly from the Operating Set
Point setting.
The Tank Probe Offset is used to calibrate control system
temperature sensing. This can improve the precision of
temperature control in the storage tank and at points of use.
This feature can also be used to compensate for building
recirculation loops (hot water returning to the storage tank)
that may cause the heating cycles to terminate prematurely.
Example: If the current sensed temperature from a
temperature probe is 120'F (49'C) and the Offset setting is
adjusted to a value other than 0', the control system would
calibrate or "offset" the sensed temperature from the probe
and the averaged tank temperature. Heating cycles would
be activated and deactivated based on the calibrated (offset)
temperature. A -5* setting results in +5' hotter water.
These settings are adjusted in the same way described for

SUPPLY GAS PRESSURE ADJUSTMENT
00
if
i re and Explosion Hazard
7F
Do not use water heater with any gas
other than the gas shown on the rating
label.
• Excessive gas pressure to gas valve can
cause serious injury or death.
• Turn off gas lines during installation.
• Contact a qualified installer or service
agency for installation and service.
Supply gas pressure shall be measured while the water heater is
not firing (static pressure) AND while the water heater is firing at
full capacity (dynamic pressure).
If the supply gas pressure to the water heater is not between the
required minimum and maximum values given in Table 3 on page
11 adjust the supply gas regulator as necessary. Adjust the supply
gas regulator(s) per the regulator manufacturer's instructions to
achieve the required "statid' and "dynamic" supply gas pressure.
Multiple Water Heater Installations:
In multiple water heater installations or in installations where
the installed water heater(s) share a common gas supply main
with other gas fired appliances; the supply gas pressures shall
be measured at each water heater with all gas fired appliances
connected to a common main firing at full capacity.
On multiple water heater installations the supply gas line
regulators shall be adjusted to provide gas pressure to each
water heater within the minimum and maximum supply pressure
requirements listed in Table 3 on page 11 with all gas fired
appliances connected to a common gas main firing at full capacity.
NOTE: A pressure drop of more than 1.5" W. C, (0.37 kPa) when
the Main Burner ignites is an indication of an inadequate supply
of gas and can lead to ignition failure, rough starts and/or rough
operation. If a drop of more than 1.5" W. C. (0.37 kPa) in supply
gas pressure occurs when the Main Burner ignites, ensure the
supply gas lines and regulator(s) are properly sized and installed.
See the requirements for Supply Gas Regulator and Gas Supply
Systems on page 13. See Supply Gas Line Installation on
page 40 and Supply Gas Regulator on page 13. Ensure all
requirements and installation instructions are maintained.
MANIFOLD GAS PRESSURE
The manifold pressure is non adjustable. The manifold gas
pressure is factory set and cannot be field adjusted. If the
manifold gas pressure readings taken on these models is off by
more than ± 0.3" W. C. from the listed values in Table 3 on page
11 call the technical support phone number listed on the back
cover of this manual for further assistance.
CHECKING THE FIRING RATE
If firing rate adjustment is required follow these instructions to
determine the actual firing rate of the water heater:
NOTE: The heaters covered by this manual are capable of
modulating their firing rate. The firing rate should be checked
with the heater operating at it's full firing rate.
1. Ensure there are no other gas fired appliances connected to
the gas meter firing during this test.
2. Contact the gas supplier to determine the heating value, in
Btu per cubic foot, of the gas supply.
3. Connect a manometer to the supply gas pressure tap. Follow
the instructions for Initial Start Up on page 53.
4. Start the water heater and ensure it is firing.
5. Check the supply gas pressure, refer to Table 3 on page
11 for correct pressure.
6. Locate the gas meter serving the water heater.
7. Time how long (in seconds) it takes for one cubic foot of gas
to be used while the water heater is firing with a stop watch.
8. Use the formula below to "clock" the gas meter and determine
the actual firing rate of the water heater based on the heating
value (Btu per cubic foot) of the gas supply:
3600 x H = Btu/hr
T
Example:
3"0 x 1050 = 300,000 Btu/hr (87.9 kW)
12.6
. 3600 = seconds in one hour.
T = time, in seconds, to burn one cubic foot of gas.
H = heating value of gas in Btu per cubic foot.
Btu/hr = actual firing rate of the water heater.
NOTE: 1050 Btu per cubic foot is a standard value for
natural gas. Standard propane gas Btu content is 2500
Btu per cubic foot. Btu values may change in certain
areas and at high elevations. Check with the local gas
utility company.
TO TURN OFF GAS
1 , Change the Operating Set Point to the lowest temperature
setting, see Operating Set Point And Differential Adjustment
on page 48.
2. When the water heater has completed its shutdown sequence
and enters the standby mode, turn the water heater's on/off
switch to the "off" position.
3. Close Main Gas Shutoff Valve, see Figure 54 on page 40.
HIGH ALTITUDE INSTALLATIONS

Fire and Explosion Hazard
• Under no circumstances should the
input exceed the rate shown on the
water heater's rating label.
• Overfiring could result in fire or
explosion.
• Gas and carbon monoxide detectors are
available.
Breathim Hazard - Carbon Monoxide Gas
Under no circumstances should
the input exceed the rate shown
on the water heater's rating label.
Overfiring could result in damage to
the water heater and sooting.
Gas and carbon monoxide detectors
are available.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
The heater models covered by this manual are certified for use
without modification for altitudes up to 10, 100 feet (3,078 m).
Most gas utility companies de -rate their gas for high altitudes,
making it unnecessary to install high altitude orifices.
For installations above the certified elevations listed above
call the technical support phone number listed on the back
cover of this manual for further technical assistance. Call
the local gas or utility company to verify Btu per cubic foot
content before calling for technical assistance and have that
information available.
NOTE: The actual firing rate of the water heater must not
exceed the input rating on the water heater's rating label
under any circumstances.
NOTE: Due to the input rating reduction at high altitudes, the
output rating of the water heater is also reduced and should
be compensated for in the sizing of the equipment.

INSTALLATION CHECKLIST
The list below represents some of the most critical
installation requirements that, when overlooked, often result
in operational problems, down time and needless parts
replacement. This is not a complete list. Before performing
any troubleshooting procedures use the list below to check
for installation errors. Costs to correct installation errors are
not covered under the limited warranty. Ensure all installation
requirements and instructions in this manual have been
maintained and followed.
1. Ensure proper clearances to combustibles are maintained
and there is sufficient room to service the water heater. See
Clearance To Combustible Materials on page 12.
2. Ensure the area is free of corrosive elements and flammable
materials. See the instructions on page16.
k7#ZTkW1c1
1 . Ensure the intake air and/or vent (exhaust) piping i's
the correct size for the installed length. See Venting
Requirements on page 22.
2. Ensure the maximum equivalent feet of pipe has not been
exceeded for the intake air and/or vent pipe. See Table 6 on
page 23.
3. Ensure the maximum number of elbows has not been
exceeded in the intake air and/or vent pipe. See Venting
Requirements on page 22.
4. Ensure the intake air screen has been removed from the
intake air connection on the water heater when installing the
water heater in a Direct Vent configuration. See Figure 18
on page 25.
5. Ensure all exterior clearances for the intake air, vent,
concentric, and low profile terminations are maintained.
See Vertical Termination Installation on page 25,
Sidewall Termination Installation on page 27, Concentric
Termination Installation on page 30 and Low Profile
Termination Installation on page 34. These clearances and
those cited by local and national codes must be maintained.
GAS SUPPLY AND PIPING
1 . Ensure a supply gas regulator has been installed for each
water heater. See the requirements for a Supply Gas
Regulator on page 13.
2. Ensure the supply gas line to each water heater meets
the minimum supply gas line size requirements. See the
requirements for the Gas Supply Systems on page 13
and the installation instructions on page 40 and 41.
CONDENSATE DRAIN
Ensure the condensate drain is properly connected to the
exhaust elbow on the water heater and draining freely to a
suitable floor drain. See Figure 8 on page 16 and Condensate
Drain Installation on page 39.
ELECTRICAL CONNECTIONS
1 . Ensure the power supply connections to the water heater
are polarity correct. See the requirements for the Power
Supply on page 13 and Electrical Wiring on page 41.
2. Ensure the water heater is properly grounded. Flame
sensing requires an adequate earth ground. If the water
heater is not properly grounded it will cause Ignition Failure.
SEQUENCE OF OPERATION
Read the Sequence of Operation below before attempting to
correct any operational problems. Refer to the Features And
Components section beginning on page 7 for the location
of various water heater components described below. See the
Sequence Of Operation Flow Chart on page 58 also.
1 . When the control system is first powered, during boot
up, it will display water heater model information during
initialization. After a few moments the control system LCD
which is part of the UIM (user interface module) will display
the default screen known as the "Desktop" screen.
2. If the control system determines that the actual water
temperature inside the tank is below the programmed
Operating Set Point minus the Differential setting, a heating
cycle is activated.
3. The control system then performs selected diagnostic
system checks. This includes confirming the low gas
pressure, blocked exhaust, blocked intake and ECO (energy
cut out) switch contacts are closed. The Blower Prover
Switch contacts are confirmed open.
4. If all diagnostic checks are successfully passed, the control
system energizes the Combustion Blower for pre -purge.
5. The control system must confirm the Blower Prover Switch
contacts close after the Combustion Blower is energized.
6. If the Blower Prover Switch contacts are confirmed closed
the control system energizes the Spark Ignition Control.
7. The control system energizes the 24 Volt Gas Valve allowing
gas to flow to the Main Burner.
8. The control system monitors the flame sensor to confirm
a flame is present at the Main Burner. If a flame is not
verified during the ignition trial period the control system will
try for ignition up to two more times. If flame can not be
verified after three trials for ignition, the control system will
lock out and display the "Ignition Failure" Fault message.
9. If a flame is verified, the control system will enter the heating
mode where it will continue heating the water until the
Operating Set Point is reached. At this point, the control
system will de -energize the 24 Volt Gas Valve and enter the
post -purge cycle (approximately 30 seconds).
10. The control system cle-energizes the Spark Ignition Control.
11. The water heaters covered by this manual are capable of
modulating their firing rate. The firing rate is dictated by the
hot water draw and various other temperature limitations.
12. The Combustion Blower will run for the duration of the post -
purge cycle to purge the water heater of all combustion
gases. When the post -purge cycle is complete, the blower is
de -energized and will coast to a stop.
13. The control system now enters the standby mode while
continuing to monitor the internal storage tank water
temperature and the state of other system devices. If the
tank temperature drops below the Operating Set Point
minus the Differential setting, the control will automatically
return to Step 2 and repeat the operating cycle.

OPERATIONAL PROBLEMS
Read and understand this instruction
manual and the safety messages
herein before installing, operating or
servicing this water heater.
Failure to follow these instructions and
safety messages could result in death
or serious injury,
This manual must remain with the
water heater.
This section of the manual is intended to be an aid in correcting
common operational problems, it is not all inclusive. The installer
may be able to observe and correct certain problems which
might arise when the water heater is first put into operation or
when it is re -fired after a prolonged shutdown. However, only
qualified service agents, as defined in Qualifications on page

INSTALLATION ERRORS
Operational problems on new installations are often the result of
installation requirements that have been overlooked rather than
failed components. IE: A "Low Gas Pressure" Fault condition
is most often caused by low supply gas pressure rather than a
defective Low Gas Pressure switch. Rough starting and rough
operation are often caused by undersized supply gas lines and/
or the absence of a supply gas regulator at the water heater.
Prior to performing any operational checks inspect the water
heater installation to ensure all installation requirements and
instructions have been maintained and followed. See the
Installation Checklist on page 57

NOTE: Contact your local distributor or call the parts department
phone number on the back cover of this manual to order a new
cleanout gasket. Have the new gasket available before removing
the cleanout cover.
For convenience, sediment removal and lime scale removal The cleanout opening is shown in Figure 64. To remove lime
should be performed at the same time. scale manually through the cleanout opening proceed as follows:
LIME SCALE REMOVAL
When water is heated dissolved minerals in the water such as
calcium and magnesium carbonate (lime scale) become less
soluble. As the water temperature rises these minerals will
precipitate or "fall out' of solution.
The amount of lime scale released from water is in direct
proportion to water temperature and usage. The higher the water
temperature or water usage, the more lime deposits are dropped
out of the water.
Water hardness also affects lime scale accumulation, With the
temperature and usage being the same, hard water will release
more lime scale than softer water.
Lime scale reduces heating efficiency as it accumulates inside
a water heater. Heating transfer surfaces become coated with
lime scale deposits which increases fuel costs to operate the
water heater. Lime scale deposits can also cause rumbling
and pounding noises as air molecules trapped in the lime scale
escape when heated. Lime scale accumulation also reduces the
life span of water heaters. For these reasons a regular schedule
for deliming should be set up.
The depth of lime accumulation in the bottom of the water
heater should be measured periodically. Inspect by removing
the cleanout cover once every 6 months at first. Deliming
maintenance should then be performed based on the time it
takes for 1 inch (2.5 cm) of lime to accumulate in the bottom of
the water heater.
Sediment and lime scale removal may be accomplished manually
through -the cleanout opening furnished on the water heater, see
Figure 64.
1. Turn off the electrical supply to the water heater.
2. The water heater must be drained, see Draining And Flushing
on page 63, follow the instructions on how to drain the water
heater.
3. Remove outer cleanout access plate from lower side of the
water heater jacket.
4. Remove the cleanout cover from cleanout opening.
5. Remove lime, scale and/or sediment using care not to
damage the glass -lining.
6. Install a new cleanout gasket if required.
7. Reinstall the cleanout cover. Be sure to draw plate up tight
by tightening screws securely.
8. Close the water heater drain valve.
9. Fill the water heater - see Filling The Water Heater on page 53.
10. Turn on the electrical supply to place the water heater back
in operation. See Initial Start Up on page 53.
11. Allow the water heater to complete several heating cycles to
ensure it is operating properly.
12. Check for water leakage.
13. Reinstall the cleanout access plate.
CHEMICAL LIME SCALE REMOVAL
To dissolve and remove more stubborn lime scale deposits, UN -
LIME@ Professional Delimer should be used.
UN-LIME8 Professional Delimer is an easy to handle patented
food grade acid formulated specifically for lime scale removal
from all types of water using equipment. Hydrochloric base acids
must not be used to delime the water heaters covered in this
manual.

It is recommended that the Temperature -Pressure Relief Valve
should be checked, to ensure that it is in operating condition
every 6 months.
When checking the Temperature -Pressure Relief Valve operation,
make sure that (1) no one is in front of or around the outlet of the

If the Temperature -Pressure Relief Valve on the water heater
weeps or discharges periodically, this may be due to thermal
expansion.
NOTE: Excessive water pressure is the most common cause of
Temperature -Pressure Relief Valve leakage. Excessive water
system pressure is most often caused by "thermal expansion"
in a "closed system." See Thermal Expansion and Closed Water
Systems on page 14. The Temperature -Pressure Relief Valve is
not intended for the constant relief of thermal expansion.
Temperature -Pressure Relief Valve leakage due to pressure build
up in a closed system that does not have a thermal expansion
tank installed is not covered under the limited warranty. Thermal
expansion tanks must be installed on all closed water systems.
DO NOT PLUG THE TEMPERATURE -PRESSURE RELIEF
