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.

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.
