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

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/durarock/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 replace.
The opening between the front of the masonry rebox and non-combustible materials such as steel studs must be sealed so heat cannot run between
the face of the wood replace and the refacing materials. Only nishing 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.

Vertical Venting
THE APPLIANCE MUST NOT BE CONNECTED TO A
CHIMNEY FLUE SERVING A SEPARATE SOLID FUEL
BURNING APPLIANCE.
This appliance is designed to attach to two 3" (76 mm) co-linear aluminium
ex running the full length of the chimney. The ue length must be a
minimum of 8' (2.44 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 exible liner will
accommodate. However, keep the exible liner as straight as possible (avoid
unnecessary bending).
Attach both the exhaust and intake ue liners to both the termination cap
& ue 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
cap.
1. If the appliance is installed into an existing chimney system, thoroughly
clean the masonry or factory-built replace.
2. The appliance has an opening on the left side of the control compartment.
A 3/8" NPT gas supply pipe must be brought near the opening.
3. Locate the centerpoint 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 sheetmetal parts of the replace into which the gas
insert will be installed.
5. If the factory-built replace has no gas access hole(s), drill one of 1-1/2"
(37-1/2 mm) or less though the lower sides or bottom of the rebox.
The access hole must be plugged with non-combustible insulation after
the gas supply line is installed.
Gas & Electrical Connections
NOTES
• When attaching the two 3 inch (51-76 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 ue collar connection
of the appliance. If facing the appliance from the front, the air
intake is located on the left and the exhaust ue on the right.

• This appliance was tested and certied as a com-
plete system with the noted termination caps and
ex liner. Only the listed termination caps/ex liner
noted below can be used. Use of termination caps
or ex liners not listed in this manual will void the
warranty and certication of this appliance. It is
also important not to enclose the termination cap
inside of a masonry chimney rain cap, or similar.
The termination must be exposed on all four sides
and above to exhaust and draw air into the rebox.
IMPORTANT
• Only persons licensed to work with gas piping may
make the gas connections to this appliance.
