INSTALLATION
WALL AND CEILING PROTECTION
FOR SAFE AND PROPER OPERATION OF THE FIREPLACE, FOLLOW THE VENTING INSTRUCTIONS EXACTLY.
HORIZONTAL INSTALLATION:
This application occurs when venting through
an exterior wall.
FIGURES 2a-c.
Having determined the air terminal location, cut and
frame a hole in an exterior wall with a minimum square or round opening of 9½".
(As an alternative to framing, a vent pipe shield may be installed, ensuring a 1"
clearance to combustibles.
See Figure 6
.)
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 framework or to the shield plate
(in the case of a finished wall) and
secure the shield through the open-
ing to the interior wall.
The final lo-
cation of the vent pipe shield should
maintain the required clearance to
the 7" vent pipe / liner. Do not fill this cavity with any type of material.
Apply
a bead of caulking all around and place a firestop spacer over the vent
shield to restrict cold air from being drawn into the room or around the
fireplace. Ensure that both spacer and shield maintain the required clear-
ance to combustibles. 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 3.
Installation kits for
various 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 9½ inch openings in the
ceiling and the roof to provide the minimum 1 inch clearance between the fireplace
pipe / liner and any combustible material. Try to center the exhaust pipe location
midway between two joist to prevent having to cut them. Use a plumb bob to line up
the center of the openings.
DO NOT FILL THIS SPACE WITH ANY TYPE OF MATERIAL.
A vent pipe shield will prevent any materials such as insulation, from filling up the 1"
air space around the pipe.

port.
2.
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 finished ceiling), and secure over the opening in the ceiling.
FIGURE 8.
A firestop must be placed on the
bottom of each framed opening in a roof or ceiling that the venting system passes
through.
FIGURE 7.
Apply a bead of caulking all around and place a firestop spacer
over the vent shield to restrict cold air from being drawn into the room or around the
fireplace. Ensure that both spacer and shield maintain the required clearance to
combustibles. Once the vent pipe / liner is installed in its final position, apply
sealant 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 prevent any
materials, such as insulation, from filling up the 1"
air space around the pipe.
