L.
Install Firestop/Spacer at exterior wall.
Install SV4.5HF Firestop/Spacer, provided
with the power vent kit, over the opening at
the
exterior
side of the framing, long side
up, with the 3 inch spacer clearance at the
top as shown in
Figure 23
, and nail into
place.
(The Firestop/Spacer may also be installed
over the opening at the interior side of the
framing).
M.
Install the Power Vent termination.
For the last step, from outside the exterior
wall, slide the collars of the termination onto
the adaptor (the outer inside the outer and
the inner outside the inner) until the termi-
nation seats against the exterior wall sur-
face to which it will be attached. Orient the
housing of the termination with the arrow
pointed upwards. Secure the termination
to the exterior wall.
The termination must
not be recessed into the exterior wall or
siding
by more that the 1-1/4” (32 mm) as
shown in
Figure 24
.

The Power Vent termination has been
designed to perform in a wide range of
weather conditions. Our terminations meet
or exceed industry standards.
When selecting the location of your ter-
mination, do not place the termination
where water from eaves and adjoining
roof lines may create a heavy flow of
cascading water onto the terminations. If
the termination must be placed where the
possibility of cascading water exists, it is
the responsibility of the builder to direct
the water away from the termination cap
by using gutters or other means.
Take care to carefully follow the Installation
Instructions for the termination, including
the use of silicone caulking where required.
To help minimize water infiltration it is recom-
mended that the Firestop/Spacer (SV4.5HF) be
installed on the exterior side of the wall.

IMPORTANT: The vent termination is hot
while in operation and for a period of time
following the use of the fireplace. Young
children should be carefully supervised
when they are in the same area as a hot
termination.
