CHIMNEY CONNECTION

Chimney installation must conform to both national and local code requirements. The chimney must be lined
with one 2" or 3" diameter liner for intake and one 3" diameter liner for exhaust. The minimum and maximum
vent lengths are 10 and 35 feet respectively. Recommended kits come in 3 lengths:
1-2" & 1-3" DOUBLE PLY ALUMINUM LINER-INLET AND EXHAUST & 2-3" TO 2" REDUCER:
While the liners must be continuous from the appliance to the terminal, to achieve the needed length, they may be
coupled, using an approved coupler.
We recommend that exhaust vents that pass through unheated spaces,
such as tall exterior chimneys, be wrapped in a protective sleeve to minimize
condensation and reverse fl ow symptoms. See Trouble Shooting for details.
This appliance is approved for use with a 2" liner for air intake and a 3" liner
for exhaust. For best performance, however, it is recommended to use two 3"
liners.
If a 2" liner is used for the intake, it may be necessary to adjust the primary air
shutter.
A. OUTSIDE: Slip the one end of a liner a minimum of 2" over the
sleeve of the air terminal. Secure using 3 screws. Then seal the
joint and screw heads with high temperature sealant. Repeat
with the other liner.
NOTE: We recommend that the other end of the exhaust
liner be marked to eliminate the exhaust liner being
connected to the intake collar at the appliance.
B. Gently stretch the liners to the required lengths and insert into
the chimney. Trim and fi t the fl ashing plate to suit the chimney
termination. Place the air terminal onto the top of the chimney.
Make weather tight by sealing with caulking (not supplied).
Fasten to the chimney with screws and plugs (not
supplied).
C. INSIDE:
connection assembly using the same procedure as before,
ensuring that the marked exhaust liner is attached to the
exhaust collar.
D.
Detach the two screws from the back of the fi rebox and remove
the panel, as illustrated.
E.
Reaching in through the appliance, manoeuvre the vent
connection assembly through the openings in the
fi rebox top, taking care not to damage the gasket. In
case of a low ceiling fi replace, the extension should
be removed and reinstalled after the vent connection
is secured to the fi rebox. Attach the restrictor plate
to the centre stud and secure the assembly using
the three studs and ¼-20 hex nuts.
