NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
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 39. This can be
purchased at your local dealer.

Installing the Square Horizontal Termination (SV4.5HT-2)
M. Install the desired termination -
1. Install the square termination (SV4.5HT-2)-
For the last step , from outside the exterior wall,
slide the collars of the termination onto the
adapter (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 de-
signed 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 in. (711 mm). pipe.
K. Attach termination adapter - Attach the
adapter (adapter - SV4.5RCH - provided with the
termination) to the vent section or telescoping
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).
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 in. (178 mm) to 11-1/4 in. (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 23. This table
lists the additional venting components needed
(in addition to the termination and adapter) for
a particular range of wall thicknesses.
L. Install Firestop/Spacer at exterior wall
- When using the square termination, install
SV4.5HF (Secure Vent), SF4.5HF (Secure 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.)

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.
