3.2
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 Napoleon 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 chimney cap, 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 condensa-
tion 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.
3.2.1
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.
3.2.2
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 sup-
plied). Fasten to the chimney with screws and
plugs (not supplied).
3.2.3
INSIDE: Remove the securing screw from the
front of the vent mounting plate. Pull the vent
mounting plate only, back into the track, to the
front stop. Start the slider back into position.
Re-secure the screw. The insert may now be
pushed into its fi nal position inside the wood
burning appliance, and the screw tightened until
the slider has been pulled tight to the front stop.
3.2.4
Route the fl ex liners through the slider. Attach
and secure the liners to the vent mounting plate
using the same procedure as before, ensuring
that the marked exhaust liner is attached to the exhaust collar.
