WALL AND CEILING PROTECTION

For safe and proper operation of the fireplace, fol-
low the venting instructions exactly.
HORIZONTAL INSTALLATION:
This application occurs
when venting through an
exterior wall. FIGURES
4a-d. Having determined
the air terminal location,
cut and frame a hole in
an exterior wall with a
minimum square
round opening of 11½".
(As an alternative to fram-
ing, a vent pipe shield
may be installed, ensur-
ing a 2" clearance to
combustibles.
OR
FIGURE 25
1. Mark and cut the vent pipe shield to the determined
depth of the combustible wall. Apply a bead of caulking
(not supplied) to the shield plate, centre a firestop spacer
over it and secure the shield to the firestop spacer. Apply a
bead of caulking all around the framed opening of the vent
shield or the firestop spacer. Place the spacer/shield as-
sembly over the framed opening in the wall and secure.
This will restrict cold air from being drawn into the room or
around the fireplace. The location of the vent pipe shield /
firestop assembly must maintain the required (2") clear-
ance to the 7" vent pipe / liner. Do not fill this cavity with any
type of material. Once the vent pipe / liner is installed in its
final position, apply sealant between the pipe / liner and
the firestop spacer.

VERTICAL INSTALLATION: This application occurs when
venting through a roof. FIGURE 2. Installation kits for vari-
ous roof pitches are available from your Napoleon dealer.
See Accessories to order the specific kit required.
1. Determine the air terminal location, cut and frame
11½ inch openings in the ceiling and the roof to provide the
minimum 2 inch clearance between the fireplace pipe /
liner and any combustible material. Try to centre the ex-
haust pipe location midway between two joist to prevent
having to cut them. Use a plumb bob to line up the centre of
the openings.
Do not fill this space with any type of material.
A vent pipe shield will
prevent any materi-
als such as insula-
tion, from filling up
the 1" air space
around the pipe. Nail
headers between
the joist for extra
support.
2. Apply a bead of caulking (not supplied) all around the
vent shield and place onto the firestop spacer. Secure.
Apply a bead of caulking to the framework and secure over
the opening in the ceiling. FIGURE 27. Ensure that both
spacer and shield maintain the required clearance to
combustibles. Place over the framed opening and secure.
This will restrict cold air from being drawn into the room or
around the fireplace. A firestop must be placed on the bot-
tom of each framed opening in a roof or ceiling that the
venting system passes through. FIGURE 28. Once the
vent pipe / liner is installed in its final position, apply seal-
ant between the pipe / liner and the firestop spacer.
3. In the attic, after the pipe /
liner has been installed, slide
the vent pipe collar down to
cover up the open end of the
shield and tighten. This will pre-
vent any materials, such as in-
sulation, from filling up the 1" air
space around the pipe.
