Chimney Connection - Napoleon Oakville Series Installation Manual

2.2

chimney connection

Chimney installation must conform to both national and local code requirements. The chimney must be lined with
one 3" (76mm) diameter liner for intake and one 3" (76mm) diameter liner for exhaust. The minimum and maximum
vent lengths are 10 feet (3m) and 45 feet (14m) respectively.
Recommended kits come in 4 lengths:
2-3" DOUBLE PLY ALUMINUM LINER-INLET AND EXHAUST:
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 and sealant.
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 flow symptoms. See
"troubleshooting" section for details. This appliance is approved for use
with a 3" (76mm) exhaust and air intake.
OUTSIDE: Slip the one end of a liner a minimum of 2" (51mm)
A.
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.
Gently stretch the liners to the required lengths and insert into the chimney. Trim and fit the flashing plate
B.
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).
INSIDE: Remove the securing screw from the front of the vent mounting plate. Pull the vent mounting
C.
plate only, back into the track, to the front stop. Start the slider back into position. Re-secure the screw.
The appliance may now be pushed into its final position inside the wood burning appliance, and the screw
tightened until the slider has been pulled tight to the front stop.
note:
Prior to sliding the appliance into
place, high temperature-rated insu-
lation should be packed around the
linear in the damper area to prevent
air flow from entering the chimney
from the home. Not doing so will
have a negative impact on the ef-
ficiency of the appliance.
Route the flex liners through the slider.
D.
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.
We recommend the following method of sealing
off the damper area around the liner:
Measure the throat of the appliance and mark this
shape on a piece of 24 gauge sheet metal (flue
cover). Cut a 6 3/4" (171mm) hole to lie directly
below the appliance flue opening. Allow 2" (50mm)
of material for a flange on all sides and cut to these
measurements. Bend down the flanges. If you have
never done this before, it might be a good idea to
make a cardboard pattern and test it first. Fasten
this flue cover in position as high as possible with
two masonry screws per side through the flanges
into the appliance.
