Minimum Clearances to Combustibles
The clearances listed below are minimum distances unless otherwise stated.
A major cause of fires is failure to maintain required clearances (airspace) to combustible materials. It is of the greatest importance that this decorative
gas appliance is installed only in accordance with these instructions.

• A non-combustible mantel may be installed at a lower height if the
framing is made of metal studs covered with a non-combustible board.
The non-combustible mantel, when installed at a lower overall height,
may not be lowerthan 6" (152 mm) from the top of the fireplace opening.
• All material used must be non-combustible.

Using Steel Studs and Concrete Board Over Masonry Brick Fireplace
The masonry front brick facing can be removed and replaced with non-combustible materials such as steel studs and concrete board/dura rock/micor board
as per diagram 1, only if safe to do so. Steel stud may also be placed in front of the masonry brick if left in place. This is the preferred method depending
on the condition of the masonry brick fireplace.
The opening between the front of the masonry firebox and non-combustible materials such as steel studs must be sealed so heat cannot
run between the face of the masonry fireplace and the refacing materials. Only finishing materials such as tile, stone, brick, or similar materials
that are non-combustible may be used. Use materials that are uniform so that when the unit is positioned, there are no visible gaps on the sides or top
of the surround.

Only people licensed to work with gas piping may
make the gas connections to this appliance.
1. If the appliance is installed into an existing chimney system, thoroughly
clean the masonry or factory -built fireplace.
2. The appliance hasan opening on the leftside of the control compartment.
A 3/8" NPT gas supply pipe must be brought near the opening.
3. Locate the centre point where the vent will pass through the chimney,
above the appliance. Move the appliance to the installation location.
Ensure that the insert is level.
4. Do not cut any sheet metal parts of the fireplace into which the gas
insert will be installed.
5. If the factory -built fireplace has no gas access hole(s), drill one of 1-1/2"
(37-1/2 mm) or less through the lower sides or bottom of the firebox.
The access hole must be plugged with non-combustible insulation after
the gas supply line is installed.
Vertical Venting
This appliance was tested and certified as a complete
system with the noted termination caps and flex liner.
Onlythe listed termination caps/flex liner noted below
can be used. Use of termination caps or flex liners
not listed in this manual will void the warranty and
certification of this appliance. It is also important notto
enclose the termination cap inside a masonry chimney
rain cap, or similar.
When attaching the two 3 inch (76 mm) liners to the termination
cap and prior to sliding them down the chimney, it is good practice
to mark the liners "exhaust" & "air intake". This prevents mixing up
• the liners at the flue collar connection of the appliance. If facing the
appliance from the front, the air intake is located on the left and the
exhaust flue on the right.

Gas & Electrical Connections
THE APPLIANCE MUST NOT BE CONNECTED TO A
CHIMNEY FLUE SERVING A SEPARATE SOLID FUEL
BURNING APPLIANCE.
INSTALLATION WITH 3" X 3" LINERS
This appliance is designed to attach to two 3" (76 mm) co -linear aluminum
flex running the full length of the chimney. The flue length must be a
minimum of 10' (3.05 m) and a maximum of 35' (10.7 m) long. See the
chart below for minimum distances from the roof. Periodically check that
the vent is unrestricted.
Masonry chimneys may take various contours which the flexible liner will
accommodate. However, keep the flexible liner as straight as possible (avoid
unnecessary bending).
Attach both the exhaust and intake flue liners to both the termination cap
& flue collar at the appliance with a minimum of three self -tapping screws.
Use Mil-Pac sealant to seal the pipes.
The air intake pipe must be attached to the inlet air collar of the termination
ca p.

The Gi25LE is also approved for use with a 2" liner for air intake and a
3" liner for exhaust. This would be suitable for a Class A wood burning
chimney with a minimum 6" round flue.
The chimney must be lined with one 2" diameter liner for intake and one
3" diameter liner for exhaust. The minimum vent length is 10' (3.05 m)
and maximum is 35' (10.7 m).
