This application occurs
when venting through
a roof. 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 or ½
inch openings in the ceil-
ing and the roof to provide the minimum 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 materi-
als such as insulation,
from filling up the 1" air
space around the pipe.
Nail headers between
the joist for extra sup-
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. 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 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.

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 ” x ”.
imPOrTANT: For optimum performance, The stove pipe
should rise ¼” per foot of run.
. 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 fit.
2. Apply a bead of caulking all around and place the firestop
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 final position, apply
sealant between the pipe and the firestop spacer.
HORIzONTAL INSTALLATION
For optimum performance it is recommended that all horizontal runs have a minimum ¼ inch rise per foot using
flexible venting.
For safe and proper operation of the fireplace, follow the venting instructions exactly.
Horizontal termination:
A clearance to combustibles of 2" must be maintained during the first 24” of vent-
ing when pentrating combustible walls. The firestop spacer (W500-0292) supplied with the unit should be used to
maintain this clearance. The first two feet of outer 7” diameter vent pipe, from the appliance must be wrapped in
the 1 inch thick insulation sleeve (supplied) as well as having a 1 inch air gap. Thereafter a 1” clearance to com-
bustibles may be maintained using firestop spacer (W615-0044 for use with flexible venting or rigid venting.)
