Figure 13 Installing Power Vent Horizontal Termination
Installing Power Vent Termination
• Assemble vent run to exterior wall - If not
previously measured, locate the center of the
vent on the exterior wall. Prepare an opening
as described in the appliance installation
instructions. Assemble the vent system to a
point where the terminus of the last section
is within 8 inches of the outside wall surface
where the power vent is to be mounted (refer
to Figure 12 ).
If the terminus of the last section is not within
this distance, use the telescopic vent section
SV4.5LA, as the last vent section. For wall thick-
nesses greater than that shown in Figure 12,
refer to the appliance Installation Instructions
for the additional venting components needed
(in addition to the termination and adapter) for
a particular range of wall thicknesses.
• Attach termination adapter - Attach the
adapter (adapter - SV4.5RCH - provided with the
power vent kit - #12) to the vent section telescop-
ing vent section, or elbow or appliance collar, as
shown in Figure 13 in the same manner as any
SV4.5 vent component.
• Install Firestop/Spacer at exterior wall -
Install SV4.5HF Firestop/Spacer (#13), 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 13, and nail into place.
(The Firestop/Spacer may also be installed over
the opening at the interior side of the framing).
• Install the Power Vent termination (#10)
- For the last step, from outside the exterior
wall, slide the collars of the termination onto
the adapter (the outer inside the outer and the
inner outside the inner) until the termination
seats against the exterior wall surface 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 12.
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 termination, 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.
