Gas Connection
• Only persons 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 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 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 though 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
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
flex running the full length of the chimney. The flue 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 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
cap.

• This appliance was tested and certified as a com-
plete system with the noted termination caps and
flex liner. Only the 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 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 firebox.

• 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 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.
