For optimum performance it is recommended that all
horizontal runs have a minimum 1/4 inch rise per foot
using flexible venting.
For safe and proper operation of the fireplace, follow the
venting instructions exactly.
This application occurs when
venting through an exterior wall.
Having determined the air termi-
nal location, cut and frame a hole
in an exterior wall with a minimum
square or round opening of
10½"*. (As an alternative to fram-
ing, a vent pipe shield may be in-
stalled, ensuring a 1" clearance
to combustibles.
Mark and cut the vent pipe shield to the determined depth
of the combustible wall. Apply a bead of caulking (not sup-
plied) to the framework or to the shield plate (in the case of
a finished wall) and secure the shield through the opening
to the interior wall. The final location of the vent pipe shield
should maintain the required clearance to the 8" 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 clearance to
combustibles. Once the vent pipe / liner is installed in its
final position, apply sealant (not supplied) between the
pipe / liner and the firestop spacer.

This application occurs when venting through a roof. In-
stallation kits for various roof pitches are available from
your Napoleon dealer. See Acces-
sories to order the specific kit
required.
1. Determine the air ter-
minal location, cut and
frame 10½ inch open-
ings in the ceiling and
the roof to provide the
minimum clearance
between the fireplace
pipe / liner and any com-
bustible material. Try to center
the exhaust pipe location midway between two joist to pre-
vent 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. Nail headers be-
tween the joist for ex-
tra support.
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 open-
ing in the ceiling. A firestop 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 firestop spacer over the vent shield to restrict
cold air from being drawn into the room or around the fire-
place. 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
(not supplied) 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.
