WALL AND CEILING PROTECTION
FIGURE 16
HORIZONTAL INSTALLATION
This application occurs when venting through an exterior wall.
Having determined the air terminal location, cut and frame
a hole in an exterior wall with a minimum rectangle opening
of 10" x 9".
IMPORTANT: FOR OPTIMUM PERFORMANCE, THE
STOVE PIPE SHOULD RISE ¼" PER FOOT OF RUN.
1. Assemble the shield to the spacer as shown, using the
3 shorter screws supplied.
The shield is meant to protect combustible materials within
the wall. If the shield is deeper than the combustible portion
of the wall, cut to fi t.
2. Apply a bead of caulking all around and place the fi restop
spacer over the framework to restrict cold air from being drawn
into the room or around the stove. Ensure that both spacer
and shield maintain the required clearance to combustibles.
Secure the spacer in place using the 4 longer screws sup-
plied. Once the vent pipe is installed in its fi nal position, apply
sealant between the pipe and the fi restop spacer.

VERTICAL INSTALLATION
This application occurs
when venting through a
roof.
Installation kits for vari-
ous roof pitches are
available from your Na-
poleon dealer. See Ac-
cessories to order the
specifi c kit required.
1. Determine the air terminal location and move the stove into
position. Cut and frame 9" x 10" openings in the ceiling and
the roof to provide the minimum 1 inch clearance between
the stove pipe 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 MATE-
RIAL.

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 fi nished ceiling), and secure over the open-
ing 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 stove.
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 spacer.
3. In the attic, after the pipe
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 fi lling up the 1" air space
around the pipe.

A vent pipe shield will
prevent any materials
such as insulation, from
fi lling up the 1" air space
around the pipe. Nail
headers between the
joist for extra support.
