This application occurs
when venting through a
roof. Installation kits for
various roof pitches are
available from your Na-
poleon dealer. See Ac-
cessories 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 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 open-
ings.
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 between
the joist for extra sup-
port.
2.
Apply a bead of caulking (not supplied) to the frame-
work or to the Wolf Steel vent pipe shield plate or equiva-
lent (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.
For optimum performance, it is recommended that
horizontal runs have a minimum ¼ inch rise per foot
when using
Simpson Dura-Vent or
Wolf Steel rigid vent
components and a minimum 1 inch rise per foot when
using Wolf Steel flexible vent components
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 the
required minimum opening
listed in
TABLE 2

.
(As an alternative to framing, a
vent pipe shield may be in-
stalled, ensuring the correct
clearance to combustibles.
)
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
opening to the interior wall.
The final location 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.
