J. Assemble vent run to exterior wall - If not
previously measured, locate the center of the
vent at the exterior wall. Prepare an opening
as described in Step B. Assemble the vent
system to point where the terminus of the last
section is within 7" (178 mm) to 11-1/4" (286
mm) inboard of the exterior surface to which
the SV4.5 HT termination is to be attached, see
Figure 42. 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 thicknesses greater than that shown in
Figure 42, refer to Table 8 on page 25. This table
lists the additional venting components needed
(in addition to the termination and adaptor) for
a particular range of wall thicknesses.
K. Attach termination adaptor - Attach the
adaptor (adaptor - SV4.5RCH - provided with
the termination) to the vent section or telescop-
ing vent section), elbow or appliance collar as
shown in Figure 41 in the same manner as
any SV4.5 vent component (refer to Step E).
L. Install Firestop/Spacer at exterior wall
- When using the square termination, install
SV4.5HF (Secure Vent
®
Flex ) Firestop/Spacer 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 41, and nail into place.
(The Firestop/Spacer may also be installed over
the opening at the interior side of the framing.)
M. Install the desired termination -
1.Installthesquaretermination(SV4.5HT-2)-
For the last step , from outside the exterior
wall, slide the collars of the termination onto
the adaptor (the outer over the outer and the
inner inside 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
horizontal termination must not be recessed
into the exterior wall or siding by more than
the 1-1/4" (32 mm) as shown in Figure 42.
SVHRK Snorkel Cap –The snorkel cap is
designed to be fitted into a basement window
box. The SVHRK cap is for use with flex vent
The vertical distance between the inlet and outlet
of the cap is 28" (711 mm). pipe.
IMPORTANT: The vent termination is hot
while in operation and for a period of
time following the use of the fireplace.
To prevent contact with hot surfaces,
we recommend the use of a Termina-
tion Guard. See Page 41. This can be
purchased at your local dealer.

Horizontal terminations have been designed to perform in a wide range of weather
conditions. Our terminations meet or exceed industry standards.
When selecting the locations of your horizontal terminations, do not place the termination
where water from eaves and adjoining rooflines may create a heavy flow of cascading water
onto the termination cap. If the cap 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.
