Horizontal Air Terminal Installation; Vertical Installation - Napoleon WHD31N Instructions D'installation Et D'opération

4.3.2 HORIZONTAL AIR TERMINAL INSTALLATION

Stretch the inner fl ex pipe to the required length taking into
A.
account the additional length needed for the fi nished wall
surface. Slip the vent pipe a minimum of 2" (50.8mm)
over the inner sleeve of the air terminal and secure
with 3 #8 screws. Apply a heavy bead of the high
temperature sealant W573-0007 Mill Pac (not
supplied).
Using the outer fl ex pipe, slide over the outer combustion
B.
air sleeve of the air terminal and secure with 3 #8 screws.
Seal using high temperature sealant W573-0002 (not
supplied).
Holding the air terminal (lettering in an upright, readable position),
C.
secure to the exterior wall and make weather tight by sealing
with caulking (not supplied).
If more vent pipe needs to be used to reach the fi replace, couple
D.
them together as illustrated. The vent system must be supported
approximately every 3 feet (0.9m) for both vertical and
horizontal runs. Use noncombustible strapping to maintain
the minimum clearance to combustibles.
The air terminal mounting plate may be recessed into the exterior wall or siding no greater than the depth
of its return fl ange.

4.3.3 VERTICAL INSTALLATION

This application occurs when venting through a roof. Installation kits for
various roof pitches are available from your authorized dealer / distributor. See
accessories to order specifi c kits required.
A. Determine the air terminal location, cut and frame a square opening as
illustrated in the ceiling and the roof to provide the minimum 1" (25mm)
clearance between the vent pipe and any combustible material. Try to center
the vent pipe location midway between two joists to prevent having to cut
them. Use a plumb bob to line up the center of the openings. A vent pipe
shield will prevent any materials such as insulation, from fi lling up the 1"
(25mm) air space around the pipe. Nail headers between the joist for
extra support.
B. Apply a bead of caulking (not supplied) to the framework or to the Wolf
Steel vent pipe shield plate or equivalent (in the case of a fi nished ceiling),
and secure over the opening in the ceiling. A fi restop must be placed on the
bottom of each framed opening in a roof or ceiling that the venting system passes
through. Apply a bead of caulking all around and place a fi restop spacer over
the vent shield to restrict cold air from being drawn into the room or around the
fi replace. Ensure that both spacer and shield maintain the required clearance to
combustibles. Once the vent pipe is installed in its fi nal position, apply sealant between the
pipe and the fi restop assembly.
C. In the attic, slide the vent pipe collar down to cover up the open end of the shield and
tighten. This will prevent any materials, such as insulation, from fi lling up the 1" (25mm) air
space around the pipe.
