INSTALLATION
It is imperative that this unit is installed and operated with the designed airflow and electrical supply in
accordance with this manual. If there are any questions about any items, please call the service department
at 1-866-784-6900 for warranty and technical support issues.
Mechanical
WARNING: APPLY THE APPROPRIATE WATER PRESSURE AND TEMPERATURE TO ALL FITTINGS
TO PREVENT LEAKAGE AND COMPONENT FAILURE. SYSTEM MUST BE INSTALLED IN
CONDITIONED SPACE BETWEEN 320F AND 130OF
Ensure that the service clearance is 36" to the front of the panel. The panel must also be located in
an accessible area where the audible and visual alarms can be heard and seen.
IMPORTANT!!
CORE Protection water connection requires a supervised supply line. This must be connected
immediately downstream from the building main shut-off valve or building sprinkler system. The main
shut-off valve must be supervised. A minimum water operating pressure (while the hood is spraying)
must be achieved at the hood, refer to Table 3 through Table 7.
Self -Cleaning System Options
In self-cleaning mode, the hot water solenoid opens, allowing hot water to flow to the duct and plenum of
the hood. Surfactant injects at a rate of one second per minute of wash. The diagram below shows the
Hot Water side of the utility cabinet mounted manifold that is activated during the "wash" cycle. The CORE
sprinkler water solenoid remains closed during the wash cycle.
The Appliance solenoid remains closed on top of the hood preventing hot water from spraying on the
appliances. Hot Water only flows to the duct and plenum area during the self-cleaning cycle.
The hot water fully integrated self-cleaning system uses the basic manifold with the addition of a detergent
pump and timers to control the system. When the fan power switch is turned off, the system sprays and
injects surfactant into the plenum for cleaning. The length of the wash cycle and surfactant injection are
adjustable. It is recommended that the wash time be 3 minutes, and detergent injection is 1 second every
minute.
Operating water pressure for the self-cleaning function is dependent on the total equivalent length of hood,
and generally fall between 30 to 70 psi. The maximum static pressure is 125 psi. Hot water temperatures
must be between 140' F to 170'F.
CORE Total Flood Fire System Options
In a fire condition, the CORE water solenoid is open, allowing sprinkler water to flow through the manifold.
The surfactant is injected continuously throughout the fire system activation. The diagram below shows
the Sprinkler Water side of the utility cabinet mounted manifold that is activated during a "fire" condition.
The hot water solenoid remains closed during a fire condition. The appliance solenoid on top of the hood
opens, allowing water to flow to the duct, plenum, and appliance spray bar.
The primary water inlet for fire protection of commercial kitchen hoods must use a monitored sprinkler line
or dedicated domestic water line. Duct, plenum, and appliance fire system protection is provided by this
option per UL300. Appliance protection provided by total flood protection. Duct mounted sensor
electronically activates the water spray system to extinguish duct, plenum, and appliance fires. Operating
water pressure varies depending on the hood length and generally falls between 30-70 psi when water is
spraying. Max water static pressure is 125 psi.
IMPORTANT!!
Filters must be installed for proper system operation. Filters can be removed once the system is off.

Plumbing Connections for CORE Total Flood Protection
Several field plumbing connections are required for proper self-cleaning with CORE Total Flood Protection
fire system hood operation. It is recommended that all plumbing connections be sealed with Teflon tape or
pipe dope. Use care not to contaminate the interior surfaces of the water lines when plumbing the unit, as
small particulate can clog the orifices of the spray nozzles.
1. All incoming plumbing connections are connected to the top of the CORE manifold via quick -seals,
or bell reducing couplings if the incoming pipe diameter is larger than the CORE manifold pipe
diameter. The hot water line can be PVC, copper, or stainless steel pipe only. If PVC is utilized,
there must be a minimum of 10 ft of copper or stainless steel pipe from the manifold to the PVC
connection. The CORE water line must be copper, stainless steel, or steel only. See Figure 1 and
Figure 4 for details.
2. Self-cleaning hoods with the WC option (Hot Water Wash) require a hot water connection at 140°F
to 170°F, and a minimum required PSI per Table 3 through Table 7. The maximum operating
pressure cannot exceed 70 psi. If the operating pressure is greater than 70 PSI, a water regulator
must be connected. Max water static pressure is 125 PSI. The typical water flow rate is 0.7 GPM
per foot of the hood. The spray lasts for a factory setting of 3 minutes every time the fans are
switched off.
3. A supervised water supply must be connected to the CORE inlet. This requires an unheated water
connection per the minimum required PSI, refer to Table 3 through Table 7. The maximum
operating pressure cannot exceed 70 psi. Water pressure may not drop below the minimum
recommended PSI while the hood is spraying. Pressure may not rise above 70 PSI when the hood
is spraying. If the operating pressure is greater than 70 PSI, a water regulator must be connected.
Max water static pressure is 125 PSI. The typical water flow rate is 1.5 GPM per foot of hood. The
water connection must be minimum 3/4" pipe. This must be connected to a water supply line
immediately downstream from the building's main shut-off valve or a fire sprinkler system. This
main valve must be continuously supervised. If the CORE water supply is connected to the building
sprinkler system, it is preferred that the connection come from the main sprinkler riser, or a branch
line as long as the CORE system is calculated in the overall sprinkler system capacity. For domestic
water supply, if other appliances are connected to the CORE water supply line, those appliances
must be operated during CORE system testing and taken into consideration when calculating the
size of the water pipe. Refer to Table 3 through Table 7 for hood length and pressure requirements.
4. If multiple hoods are arranged in an end -to -end or back-to-back arrangement, plumbing connecting
the hoods must be piped in the field. The plugged end of the Appliance and Plenum spray bars is
used to do this. Remove the plugs on the main hood and the adjacent hood and simply pipe the
Appliance spray bars together and Plenum spray bars together. It is important not to cross -connect
the spray bars.
5. If a remote mounted manifold is used with CORE Total Flood Protection, the appliance solenoid
will be installed at the plant.
6. There is also a non -pressurized 1-1/2 inch drain connection that must be piped. This allows water
to drain from the hood grease trough. It must be connected to the building grease trap. Hoods 10'
in length (or greater) will require 2 drains. 24" tall hoods with 20" filters will require 2 drains. All other
hoods will require 1 drain.
7. If a remote mounted manifold with a backflow preventer is used, the backflow preventer drain must
be piped according to the manufacturer's instructions.
8. Once all supply and drain lines are connected, remove one of the nozzles and flush the lines.
WARNING
All field connections between hoods, and incoming CORE Protection lines must be run with Steel,
Stainless Steel, or Copper pipe. Drain lines must be run with Brass, Stainless Steel, or Copper Pipe.
Plastic pipe cannot be used for drains, field connections between hoods, or CORE Protection
supply lines as it could fail and become hazardous.

Piping Loss Calculation for Wall Mount CORE Total Flood Protection Fire Systems
To ensure proper operation of the CORE Protective Fire System, the correct water pressure must be
achieved at the hood inlet per Minimum Operating Pressure for Lengths of Hood chart (refer to Table
3 through Table 7). For this to occur, proper sizing of the water line is required. Use the following steps
to calculate the minimum piping size.

1. Refer to Table 3 through Table 7 to
determine the CORE minimum psi
required at the hood inlet. Subtract this
value from the available psi at the panel
pressure gauge. Maximum panel
operating pressure is 70 psi. This will
be your maximum allowable pressure
drop for field -installed pipes between
the panel and the hood.
2. Most fittings add an equivalent pipe
length to the total run. Use the chart
below to calculate the equivalent pipe
length for installed fittings. If you have
multiple fittings of one type, simply
multiply the number below by the total
number of the fitting and add to the total
run length.
3. To calculate the total flowing pressure
drop between the panel and the hood,
take the total equivalent length found in
step 2 and add the total linear field -
installed pipe length. Multiply this
number by the value found in Table 2.
Gallons per minute is calculated by
multiplying the length of the hood by 1.5
GPM, this will be the friction pressure
drop between the hood and the panel.

4. Add in the pressure drop due to gravity. This must be evaluated to overcome any rise in pipe elevation
between the panel and the hood. There is .43 psi /ft of vertical rise of pressure drop.
5. Now, compare the maximum allowable pressure drop from step 1 to the calculated pressure drop from step
3. If the calculated pressure drop exceeds the maximum allowable pressure drop, increase the pipe size,
and recalculate steps 2 and 3. Continue this step until the calculated pressure drop is below the maximum
allowable.

Field Pipe Pressure Drop Calculation Example:
Wall mount panel installed with 30 feet of 3/4" linear pipe between panel and hood. (4) 90-degree elbows
are installed in the pipe run, and the pipe run has a vertical rise of 5 feet. The length of the end -to -end
hood system is 32 feet.
Hood System = 32 feet. Flow rate = 32 feet * 1.5 gpm = 48 gpm
Pressure required at hood = 44 psi.
Pressure at panel gauge = 50 psi.
Allowable pressure drop between panel and hoods: 50 psi - 44 psi = 6 psi
Equivalent length of pipe = 30 + 4 * 2.10 = 38.40 feet
Friction Pressure Drop through pipe = 38.40* 2.005 = 76.99 psi
Gravitational Pressure = 0.43 psi/ft * 5 feet = 2.15 psi
Total Pressure Drop in Field Pipe between panel and hood = 76.99 psi + 2.15 psi = 79.14 psi
Allowable pressure drop = 6 psi
This system will not work correctly because calculated pressure drop is greater than allowable
pressure drop. Pipe size will need to be change to 1-1/2 inch diameter.
Re -calculate with 1-1/2 inch pipe instead of %" pipe:
Equivalent length of pipe = 30 + 4 * 4.00 = 46 feet
Friction Pressure Drop through pipe = 46 * 0.078 = 3.58 psi
Gravitational Pressure = 0.43 psi/ft * 5 feet = 2.15 psi
Total Pressure Drop in Field Pipe between panel and hood = 3.58 psi + 2.15 psi = 5.74 psi
Allowable pressure drop = 6 psi
This system will work correctly because calculated pressure drop is less than allowable pressure
drop.

Note: Water pressure may not drop below the minimum required psi while the hood is spraying hot
water or for CORE. Pressure may not rise above 70 psi when the hood is spraying. If the operating
pressure is greater than 70 psi, a water regulator must be connected.
The chart above is for continuous back to back and/or end to end hood installations. If the pipe
connecting any hood contains excessive elbows or complicated paths, additional pressure may be
required to overcome this pressure loss. Contact engineering for clarification in these
circumstances.
When additional nozzles are added to a CORE system, beyond the standard overlapping coverage,
each nozzle is equal to 1 gpm. Each nozzle is equivalent to adding 8 additional inches of hood. To
find the new pressure requirements, add the additional length to the base hood length, then refer
to the chart above based on the new equivalent hood length.
Example: When three (3) additional nozzles are added to a CORE system, the total consumption is
increased by 3 gpm. The minimum pressure requirements can be found in the chart above, by
adding 24 inches to the base hood length.
To determine the minimum pressure requirements when CORE Total Flood Protection is mixed with
CORE Duct & Plenum Coverage, it is necessary to recalculate the system total hood length. The
equivalent hood length of Duct & Plenum coverage is equal to 8 inches per 1 foot.
Example: If you have a 10'-0" Hood with CORE Total Flood protection and a 12'-0" Hood with CORE
Duct & Plenum coverage, the total equivalent hood length is 10'-0" + (12'-0" * 0.75) = 19'-0".
The discharge coefficient, or "K Factor," is used to calculate the actual GPM through the system when the
incoming pressure is above the minimum stated in the above tables. This K factor can be applied to the
completed hood assembly. The formula below will provide the Gallons per Minute discharge rate of the
hood fire system.
Total Flowrate = K Factor x Pressure0.44

Gas Valve Installation
Gas valves are designed to shut off the flow of gas to the kitchen appliances in the event of fire system
activation. Gas valves must be installed with an upstream strainer to prevent debris from prohibiting valve
function. New pipe, properly reamed and cleaned of metal burrs, is to be used. Proper care is needed to
ensure that the gas flow is in the same direction as indicated on the gas valve and strainer. Do not
overtighten pipe connections. Pipe dope is to be applied to the male threads only. If necessary, install a
drip leg in the gas line in accordance with the authority having jurisdiction.

CORE Total Flood Coverage
The CORE Protection System for appliances depends on the proper placement of the fire suppression
nozzles. The fire system can be tailored to suit the individual needs of the appliances. It is important to
remember that the nozzles will need an unobstructed path to the cooking surface for proper fire
suppression. The overall cooking surfaces of the appliances under the hood are called the hazard zone
and will determine the fire protection system.
Hazard Zone and Nozzle Placement
The Hazard Zone consists of the cooking surface of each appliance underneath each hood. All appliances
outlined in UL300 and on the chart on the following page are suitable to be covered with the CORE total
flood system. There are specific branch appliance drop requirements for upright charbroilers and
salamanders. The lowest and highest cooking surface will determine the height of the fire suppression
nozzles. This nozzle height can range between 30 and 55 inches. For applications where the appliance is
vertical, such as an upright charbroiler, the nozzle setup will need to be adjusted. The sections below
contain more detailed information about the Total Flood system.
Proper placement of the appliance hazard zone will maximize the performance of the fire system. There
are several factors that need to be accounted for when placing the appliances under the fire system, such
as the front and side overhang measurements of the hoods with respect to the hazard zone and the
appliance clearances to combustibles. The common line placement will depend on where the appliance
hazard zone is installed under the hood. The common line is a 3/4" NPT line typically installed 24" off the
back of the hood and will supply the nozzles. This line can be extended to additional CORE Protection
hoods to continue the coverage of the hazard zone to a maximum of 48 feet.
The nozzles must be positioned along the hood length to allow Total Flood of each appliance in the
hazard zone. The nozzles must be no more than 12-inches away from the end of the hazard zone, and
the nozzles cannot be spaced further than 36" from each other. The nozzle must be no more than 18-
inches away from the front or back of the hazard zone. The pipe for the nozzle drops cannot be sleeved
in stainless steel but can be made from polished stainless steel or polished chrome -plated black iron.
Refer to Figure 4.

Upright Broiler Protection
Upright broilers, chain broilers, and cheese-melters have specific coverage requirements. Unlike
appliances with an exposed flat cooking surface, these appliances have an internal cooking surface and
only have a small opening in the face or end of the appliance.
To cover the internal hazard posed by these appliances, a nozzle must be placed at the opening and aimed
at the opposite rear corner of the appliance. This nozzle must be branched off one of the nozzle drops and
piped to the appliance opening. The drawing below illustrates how this should be accomplished. Should
the cooking surface of the appliance exceed 675 in2, an additional nozzle will be required on the opposite
of the appliance for added fire protection.

Salamander Protection
Salamanders have specific coverage requirements, unlike appliances with an exposed flat cooking surface,
these appliances have an internal cooking surface and only have a small opening in the face or end of the
appliance.
To cover the internal hazard posed by these appliances, a nozzle must be placed at the opening and aimed
at the opposite rear corner of the appliance. This nozzle must be branched off one of the nozzle drops with
a tee and piped to the appliance opening. No more than two nozzles can be utilized for a single drop.
Should the cooking surface of the appliance exceed 675 in2, an additional nozzle will be required on the
opposite side of the appliance for added fire protection.
An additional nozzle must be piped from a nozzle drop nearest the appliance, to cover the hazard
underneath the salamander. This nozzle is to be aimed at the centerline of the hazard zone, a minimum
of 30" away.

OPERATION
Prior to starting up or operating the system, check all fasteners for tightness. Ensure that the wiring is
installed properly and that all nozzles and panels are installed.
Self -Cleaning Hood
The self-cleaning hood is designed to use hot water to wash the hood plenum and immediate duct section
every time the fan switch is switched from the "ON" position on the main control panel. When the switching
action occurs, hot water sprays along the entire length of the hood and towards the back of the hood for a
factory setting of 3 minutes. During this time, surfactant is injected into the water stream for a duration of
1 second for each minute of wash time. Once the wash cycle is complete, water stops spraying, and the
hood filters are to be removed and cleaned.
Self -Cleaning System Overview
In self-cleaning mode, the hot water solenoid opens, allowing hot water to flow to the duct and plenum of
the hood. Surfactant is injected at a rate of one second per minute of wash. The diagram below shows the
Hot Water side of the wall -mounted manifold that is activated during the "wash" cycle. The CORE sprinkler
water solenoid remains closed during the wash cycle.

Check all nozzles to make sure they are installed and tight.
Install all hood filters per the filter installation configuration, see
Figure 23. There are drip blanks secured to the filters to prevent Figure 22 — CORE
water from exiting the hood between the filters. Pressure/Temperature Gauge
Open all water valves to the hood.
Fill surfactant tank with surfactant. The "Add Surfactant" light should
not be on, once the tank is full. Prime the surfactant pump with the
push-button on the face of the electrical control package.
There are 2 timers that control the water wash spray and the
surfactant injection. The wash timer, which is controlled by R3 on
the CORE printed circuit board and labeled WASH, is set to 3
minutes from the factory. The surfactant timer that is fixed and
factory set for 1 second of injection during each minute of wash time.
The injection occurs at the start of each minute. The Wash timer
setting should be verified. (See section "Self -Cleaning Water Wash
Timers" for information)
Turn the hood fan switch to the "ON" position. Fans should
operate. If they do not, check wiring. If the hood has the cold
water mist option, cold water should begin to spray.
To operate the wash cycle, simply turn the fan switch off. The wash
cycle energizes automatically and will remain on for the duration of
the wash timer setting. The wash cycle may not run if the minimum
fan run time has not been met.
Verify that the surfactant is being injected properly into the water stream.
Verify the pressure and temperature of the water via the
pressure/temperature gauge. See Figure 22. Self-cleaning pressure
should be between the required minimum psi, refer to Table 3 through
Table 7. The maximum operating pressure cannot exceed 70 psi.
Check all manifold pipe connections to ensure there are no water leaks.
Check all filters to make sure that no water is leaking back through the filters.

CORE Protection Fire System
The self-cleaning hood is required to be installed to achieve CORE Protection. The basic daily operation
of the CORE Protection system is identical to the self-cleaning hood. In the event of a hood fire, CORE
Protection is activated.
If the hood Firestat installed in the riser senses a temperature hotter than its internal setpoint or if the remote
manual actuation device (push/pull station) is pushed, an electric signal is sent to the appliance protection
fire system solenoid and the hood duct and plenum water system solenoid. Two electric water solenoids
are energized, allowing the flow of water to the hood duct and plenum and the appliance nozzles. At the
same time, the surfactant is continually injected into the water stream to help suppress the fire.
Once the fire system is activated, a "Fire System Activated" light is illuminated on the hood control panel
and an audible alarm sounds. All gas and electric appliances under the hood must be electrically
interlocked to shut off. This is achieved via a gas valve relay and/or a shunt trip breaker. A timer is also
energized upon fire system activation. The timer is factory set for 15 minutes and keeps the duct and
plenum water spray system running for a minimum of 15 minutes. The same timer also keeps the appliance
water spray running for a minimum of 15 minutes. This is necessary to ensure the complete extinguishment
of all fire potential.
The fire system is electrically operated and thus requires a battery backup system. In the event of a loss
of building electrical power, all gas and electric appliances under the hood must be electrically interlocked
to shut off. This is achieved via a gas valve relay and/or a shunt trip breaker. The battery backup will
automatically energize upon a loss of power. The battery backup will monitor the fire system circuit for up
to 24 hours and be able to operate the fire system circuit for a minimum of 30 minutes. Once power is
restored, the battery will automatically recharge.
CORE Protection Test Mode Overview
The CORE Protection System has an integrated option for testing. This test mode, when active, will shut
down the appliance coverage solenoid and prevent the water from spraying on the appliances. It will allow
activation of the fire system, including the water spray in the duct and plenum, audible alarm, shunt trip
breaker (if applicable), and shut -down of appliances via gas valve reset relay. This mode will also activate
any additional CORE package attached to the system, including any Pollution Control Unit CORE Protection
systems and other hood -mounted CORE Protection systems.
Please note that the appliances must be started before test mode is entered on any CORE Protection
package for proper demonstration of this function. If the CORE Protection System is left in Test Mode for
more than 15 minutes, the appliances will be shut down. This is to prevent cooking operations from
occurring while the appliances and ventilation system are not protected.
CORE Protection Reset Overview
There are multiple actions required to reset the fire system. First, the duct Firestat must be cooled to below
its internal set point, and the remote manual actuation device (push/pull station) must be reset by twisting
the button clockwise until it resets. Once both of these devices have been reset, the timer will automatically
stop the fire system once its time duration has ended. An alternative method to bypassing the timer is to
press the fire system reset button on the face of the electrical control package. This will de -energize the
timer and reset the system.
NOTE: The Firestat must be cool, and the remote manual actuation device (push/pull station) must
be reset for this button to work.
After a fire, full inspection by a certified professional must be conducted prior to restarting the fire
system.

Component Description
The following section lists the major controls and components used in the self-cleaning hood and the CORE
Protection fire system.
Self -Cleaning Spray Bar/CORE Duct and Plenum Coverage
The self-cleaning hood contains a spray bar that extends the entire length of the hood immediately behind
the filters in the hood. The bar is 3/4" brass fittings with nozzles that spray directly toward the back of the
hood. The same spray bar is used in hot water wash, cold water mist, and CORE Protection fire systems.
Water enters the spray bar through a 3/4" quick -seal. The other end of the spray bar is plugged. If hoods
are installed back-to-back or end -to -end, the plugged end of the spray bar can be unplugged and connected
to the next spray bar.
Figure 26 — Spray Bar Assembly
Notes
1. All pipe will be Copper. Pipe fittings will be Brass/Copper Pro -Press.
2. Sections of pipe and teas can be pre -assembled for use. The malorlty of
the length will use these parts.
3. Ends will be made using a Street elbow Inside a quick -seal. See Detail A
and El.
4. The Variable length section of pipe will be used to eompiete the spray
assembly.
S. an hoods 10' and longer, a tee wlI! he Instslled at the center at the spray
bar for support. This will ba a 314' x 314" NPT x 314" Pro -Press Tee with a
plugged quick -,seal. If this interferes with riser, move supports to both sides
of riser.
6- Riser plumbing will be 114" NPT- Brass. The placemernt of the elbow is
dependant on the riser location. 'rhe nozzle needs be tenterad, both
vertically and horizonially, within the riser. Riser nozzle must follow table to
right. Maintain 13" nozzle spacing.
7. When riser nozzle Is located directly under center of riser on spray bar,
main elbow must paint upwards-

CORE Protection Fire System Printed circuit board
The CORE Fire System printed circuit board is a microprocessor based controller that
provides all the necessary monitoring, timing, and supervision functions required for the
reliable operation of the CORE Protection Fire System.
Under normal conditions, the "Fire System Activated" light is flashing one brief flash every
3 seconds, indicating the CORE system is armed and ready. If a fault is detected
anywhere in the CORE system, the audible alarm will periodically sound, and the "Fire
System Activated" light will flash a fault code to indicate the fault that was detected. This
fault code consists of a series of flashes followed by a pause. Simply count the number
of flashes between the pauses and refer to the chart below to find the cause of the fault.
Any fault is extremely important and must be dealt with and rectified immediately to
ensure continued CORE protection.
The connections for building fire panels are located at AL1 and AL2 as dry contacts.
For remote mounted Ansul Automans, use terminals AU1 and AU2. This will provide a
dry contact connection point to provide power for activating the Ansul Automan.

Setting switch 8 to its Closed (On) position connects a 120 Ohm

terminating resistor to the interlock network. This switch must be
Closed if this unit is at either physical end of the interlock network
cable, otherwise it must be Open (Off).
• Each unit has a unique address based on the DIP switch 1-4 settings, 15 units max on a network.
• If address is 0 (all switches off), the unit will not accept or send any network traffic.
• The unit that has switch 5 on will be the "master" and be in charge of polling all the units below it
and waiting for a reply. The lack of 3 replies in a row will cause an "interlock network supervision
fault." All units will be polled in a burst every 3 seconds.
• For all non -master units, the lack of being polled for 10 seconds will cause an "interlock network
supervision fault."
• Any unit detecting a fire condition will broadcast the notification once every second for as long as
the condition persists.
• When the Fire condition is cleared, 10 notifications will be sent, one every second.
• Any unit detecting a supervisory fault will broadcast the notification every 2 seconds until the
condition is cleared.
• When the supervisory fault condition is cleared, 10 notifications will be sent, one every 2 seconds

Local Alarm Muting
Depressing the fire system reset button can mute the local alarm. This will disable the sounder for 4 hours
under specific conditions. The table above shows which errors can be muted. It should be noted that the
fault will not clear until the fault condition is corrected.
CORE Appliance Test Mode
The CORE Appliance Test Mode allows the hood to be tested with operational appliances without
discharging the system on the appliances. Once the appliances are started, test mode can be entered
without the appliances shutting down for 15 minutes. However, once the fire system is activated, the shunt
trip (electric appliances) and the gas valve will be locked out until test mode is deactivated.
"During AC power failure, all gas appliances will be shut down. Electrical appliances will shut down on
building power loss.

CORE Protection Supervised Loops
NOTE: There must be adequate clearance above the hood to access components. Service
clearance of 18-inches is recommended.
The supervised loops are integral to proper operation and activation of the CORE protection system. All
CORE protection systems have two supervised loops; each loop consists of two conductors, one positive
and one negative. One loop is dedicated to all sensors, while the other is dedicated to all manual actuation
devices (push/pull stations). The supervised loop connections are located at the front edge of the hoods
for accessibility. Connections beyond the hood, like the connections at the manual actuation device, must
be made with a plenum -rated wire. It is recommended to use a two -conductor Belden 6320UL, 18 AWG,
wire, or similar for these connections.

CORE Protection Firestat
NOTE: There must be adequate clearance above the hood to access components. Service
clearance of 18-inches is recommended.
The Firestat is a device installed in the riser of the hood, at the duct connection, that measures temperature.
The standard temperature setting is 360oF. Depending on heat produced by appliance, a higher rated
temperature Firestat will be required. If a temperature higher than the setpoint is sensed, the Firestat
contacts will close and energize the electrical control board. The fire system will activate, the system will
run for a minimum of 15 minutes and then recheck the temperature. If the temperature is still higher than
the setpoint, the process restarts immediately.
The Firestat has 2 black wires and 2 white wires, these wires must be connected into the supervised loop.
Use high -temperature wiring when installing Firestat components. High -temperature wire -nuts or terminal
blocks must be used. There must be one sensor installed for every 12 feet of hood length.
Multiple sensors are wired in parallel in the supervised loop. The Firestat may be installed on the opposite
side of the quick seal for access in the duct.
Non -Solid Fuel Appliances (Rated 450°F)
Non -solid fuel appliances rated for 450°F will not require additional firestats, regardless of the configuration
and length of ductwork.
Non -Solid Fuel Appliances (Rated 600°F)
Non -solid fuel appliances rated for 600°F will require downstream detection if the duct run contains any
horizontal section over 25 feet in length. Downstream detection should be installed at the end of a
horizontal section. Duct layouts that include less than 25 feet of horizontal ductwork will not require
additional detection.
Solid Fuel Appliances (Rated 700°F)
Solid fuel appliances produce effluents that can accumulate inside the duct, especially in long horizontal
duct runs. Sparks from solid fuel appliances can travel into the ductwork and create fires that occur beyond
the point where the hood riser Firestat can detect them. Additional downstream Firestats ensure that these
duct fires are detected, and the fire system actuates. Solid fuel applications require 600°F rated Firestats
and SOLO filters.
In addition to the 600°F rated Firestat, located in the hood riser, a second Firestat is required at the duct
discharge for solid fuel applications when the ductwork exceeds 10 feet in length or contains horizontal
runs. Even if the entire duct run is inaccessible, this additional Firestat is still needed. Mounting a Firestat
in the fan may be an option. On duct runs longer than 50 feet, a third Firestat will be required somewhere
in the duct run, ideally at the end of a horizontal run, if present. Duct runs longer than 100 feet will require
additional Firestats, contact Factory Service Department for more information.
Note: When additional Firestats are required, install in an accessible location near an access door,
hood riser, or fan. The door will provide access to install, clean, and replace the Firestat when
needed. If a PCU is equipped with electronic detection, PCU Firestats can serve as downstream
detectors, if present. The temperature rating of the Firestat in the duct should match the temperature
rating of the Firestat in the riser.

CORE Protection Manual Actuation Device
The push/pull station is a remote manual actuation device to activate the fire system.
This remote manual actuation device (push/pull station) contains one set of normally
open contacts, and mounts to any standard junction box. When the front button is
pressed, the electrical connection to the fire system is completed, thus activating the fire
system.
The remote manual actuation device (push/pull station) should be mounted at a point of
egress and positioned at a height determined by the authority having jurisdiction (AHJ).
This position is usually 10 to 20 feet from hood and 42 to 48 inches above the floor.
Multiple remote manual actuation devices (push/pull stations) are acceptable to use in the
CORE system and are wired in parallel per the electrical schematic. The remote manual
actuation device (push/pull station) is reset by twisting the push button clockwise until the
internal latch is released.
The clear protective cover must be installed to protect the device from accidental
activations. This cover is provided as part of the manual actuation device. Below are the

The surfactant tank used on the CORE protection system
has a capacity of 2 gallons. The tank contains a low
surfactant switch to retain 1 gallon for CORE protection by
disabling injection during the self-cleaning cycle. In the event
of a fire, the surfactant is continuously injected into the water
spray to help suppress the fire. One gallon of surfactant will
last for approximately 15 minutes of fire protection. If the low-
level sensor is activated, an "Add Surfactant' light will
illuminate on the control panel. To reset light, simply fill the
surfactant tank with surfactant.

CORE Protection Waterline Supervision
The CORE Total Flood manifold is listed for use with water pressures
up to and including 70 psi (operating pressure) and 125 psi (static
pressure). When the inlet connection to the manifold exceeds the
max listed pressures, a pressure reducing valve water pressure
regulator must be installed. The pressure reducing valve is capable
of reducing the wet pipe sprinkler line supply pressure and flow rate
down to the CORE control package requirements. Since the valve
is capable of shutting down the water flow, it must be monitored to
ensure the valve is open. The pressure reducing valve is an Elkhart
Brass UR series and is supervised by a Potter PCVS2 Switch. The
valve is available in 1-1/2" NPT (UR-20-Series) and 2-1/2" NPT
(URFA-Series). The pressure reducing valves are rated for use up to
and including 400 psi.
The Pressure Supervision Switch, part number PL is used to verify
incoming water pressure. This switch is preset at 40 psi, but is
adjustable, up to 60 psi, to account for different length hood systems.
This switch should not be used if the minimum required pressure is
greater than 60 psi.

The CORE panel contains two isolated inputs for auxiliary supervision of pressure reducing valves and
pressure switches. Each Supervision device above has two single -pole, double -throw switches. These
switches may be wired in parallel to the CORE panel terminals H1 D and 39. When a fault is detected, the
CORE board will shut down the gas valve and shunt trip, trigger a local trouble signal, and alert all attached
CORE packages. Alternatively, the switches from each device could be connected to the trouble input of
the building fire alarm panel to indicate a trouble condition. Both methods are shown below.

Battery Backup
The CORE system contains a battery backup. During a power loss, the "Fire System Activated" light will
flash 11 times between pauses indicating the power loss.
The batteries must be replaced every 2 years, from the date of fire system commissioning. Part number
PS-1270-F2, two required. Although the batteries are hot-swappable, which means they can be replaced
while there is input power to the control. For your safety, all sources of power must be removed from the
control before replacing the batteries. To replace the batteries, unplug the battery cable from the J1
connector on the CORE printed circuit board. Then remove the retaining strap holding the batteries in place.
Remove the batteries from the cabinet. Transfer the fuse and cable set from the old batteries to the new
batteries being extremely careful to observe the RED and BLACK lead and terminal colors. Reinstall the
batteries in the cabinet and reconnect the battery plug to J1. The batteries are lead -acid type and are
recyclable; please dispose of the old batteries properly.
During extended periods of inactivity where the CORE system will be without AC power for more than 2
days, such as a shutdown or natural disaster, it is best to decommission the CORE system by disconnecting
the batteries. This will prevent any damage to the batteries through complete discharge. When the system
becomes active again, commission the system by reconnecting the batteries and allowing them to charge
for 48 Hrs.
Figure 49 — Battery Backup
Power Supply Adjustment Figure 50 —
To properly charge the batteries, the power supply must be adjusted to output 27.5V Power Supply
DC. This can be checked with an accurate digital voltmeter placed across Terminals �.
H 1 D and N 1 D. To adjust the output voltage, place a small flat -bladed screwdriver into
the yellow dial. By turning this clockwise, you will increase the voltage.

Heat Recovery Coil (Optional)
An optional heat recovery coil is available with CORE hoods. The coils are factory -installed under each
hood duct (riser) connection. Warm exhaust air passes through the coils and heats the water running
through the coils. The water is used to pre -heat the water supply to the hot water heater(s) for the facility.
The self-cleaning function of the hood continually cleans the surface of the coil to ensure proper heat
transfer. It is very important to ensure that the high -efficiency hood filters remain in use in the hood.
Each hood equipped with a coil system has a 3/4 inch NPT inlet and outlet connection. If multiple hoods
are on the same system, they should be piped in series, before the water heater, to maximize energy
recovery. If the coil pressure drop is excessive for an "in series" configuration, the coils may be piped in
parallel to reduce water pressure drop. It is important to keep the piping runs similar when piping in parallel
to keep flow rates through all coils similar. Field pipe size must be sized to provide adequate hot water for
the building appliance usage, including the self-cleaning operation of the hood. If the hood covers multiple
appliances, the coil performance will be best if the water enters the end of the hood that covers the lower
temp appliance first. The max static water pressure in the system should be 150 psi.
It is recommended that an expansion chamber, check valves, ball valves, and pressure relief valves are
field installed in the system, as shown in the diagram below. As the water heats up in the system, the water
volume can increase, therefore causing the pressure to increase.

Each coil is factory installed and is equipped with manual shut off valves on both the inlet and outlet for
service. With these valves in the off position, no water will flow through the coils. The coils are also
constructed with brass union connections, so the coil can be removed for further cleaning or service. When
removing a coil, break the unions loose and allow the water to drain into the hood trough to empty the coil.
It is recommended that a second water supply be piped directly to the hot water heater, as shown in the
diagram above so that the facility will have hot water during coil service. Check valves and ball valves
should be field installed, as illustrated to allow for proper service.
Inlet and outlet pressure/temperature gauges are installed to monitor the performance of the coil. With
water flowing and the hoods operating over hot appliances, there should be a 5-30°F temperature rise
noticed from the coil inlet to the outlet. Air pressure drop through the coil is negligible but can be estimated
with the formula below. Water pressure drop is more significant and can be estimated with the formula
below or from the lookup table below:
Coil Air Pressure Drop (in. w.c.) = 1.25E-8 x CFM2
Coil Water Pressure Drop (psi) = 0.054 x GPM2
Coil Water Pressure Drop (FT. H2O) = 0.125 x GPM2
Water temperature can also be remotely monitored. Thermistors are installed on both the entering and
leaving side of each coil for temperature monitoring. Thermistors are rated at 10Kohm and have a 2 wire
connection. These get connected to the packaged prewire controller or building monitoring system.
Reference the CASI_ink manual for more information regarding sensor wiring.

MAINTENANCE
To guarantee trouble -free operation of this system, the manufacturer suggests following these guidelines. Most
problems associated with unit failures are directly related to poor service and maintenance. Record any
maintenance or service performed on this equipment in the documentation section located at the end of this
manual.
General Maintenance
1. Hood filters must be maintained on a daily basis to ensure proper airflow and grease extraction.
2. All water connections must be verified for tightness and leak -free operation.
3. The "Add Surfactant" indicating light will illuminate when the surfactant tank is'/2 empty. Surfactant must
be added immediately to guarantee proper cleaning of the hood duct and plenum and proper fire
protection.
NOTE: Filters must be removed from the hood every 3-months. Inspect and clean filters per the
recommendations in the Hood Installation, Operation, and Maintenance Manual.
ATTENTION!!
When servicing or cleaning ductwork, all Hood CORE, PCU CORE, and interlocked fire
systems must be placed in test mode to prevent accidental discharge.
Every 6 months
1. Clean all duct sensors in hood duct connections (if equipped), inspect the hood duct and plenum areas
for excess buildup of grease/creosote.
2. The mainline strainers in the manifold must be cleaned.
3. Verify proper system activation via the supervised loops. This includes all firestats, pull stations, and any
other activation points in the supervised loop.
4. Check surfactant injection and battery backup.
5. Check all nozzles for proper and evenly distributed water flow. If nozzles are clogged, clean or replace.
6. Check drain(s) on hood to verify there is no blockage. Improper drainage could cause hood leaks or
water to back up into trough and overflow onto appliances.
7. Inspect the surfactant pump for proper operation and ensure liquid level sensor in the surfactant tank is
operational. Test by manually lowering the sensor to verify if the "Add Surfactant' light illuminates.
8. Verify the system has proper water pressure and temperature per the labels on the unit.
9. Check gas valve operation to ensure the gas valve fully closes during system activation. Also, clean the
strainer upstream of gas valve.
10. Fill surfactant tank with surfactant.
Every 2 Years
1. Replace batteries for the CORE Protection Systems. The replacement battery part number is PS-1270-
F2; two are required. Once the battery is disconnected, the connected equipment is not protected from
power outages. The new battery must be installed immediately. Refer to the replacement battery
installation guide for more details.
2. Inspect the condition of all wires and plumbing. Plumbing should be free of corrosion, and wire insulation
must be in good condition.
Decommissioning
If it should become necessary to disconnect the CORE system from AC power for an extended period of
time (more than 2 days), the batteries should be disconnected to prevent them from being damaged due
to complete discharge.
After A Fire
1. Inspect and/or Replace all nozzles.
2. Inspect all piping connections for tightness.
3. Inspect all hood lights for proper seals and security.
4. Inspect all wiring and Hood insulation to ensure all are in good condition.
