Termination
SV4.5 HT-2
Termination
Horizontal terminations have been designed to perform in a wide range of weather condi-
tions. Our terminations meet or exceed industry standards.
When selecting the locations of your horizontal terminations, do not place the termina-
tion where water from eaves and adjoining rooflines may create a heavy flow of cascad-
ing 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.

To help minimize water infiltration it is
recommended that the Firestop/Spacer

side of the wall.

For thicknesses greater
than 10", see Table 7
It is important to maintain the required clear-
ances to combustibles: 1" (25 mm) at all
sides for all vertical runs; and 3" (76 mm) at
the top, 1" (25 mm) at sides, and 1" (25 mm)
at the bottom for all horizontal/inclined runs
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 6 in. (152 mm) to 9-1/4 in. (235 mm)
inboard of the exterior surface to which the
SV4.5 HT termination is to be attached, see
Figure 28. 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 28, refer to Table 7 on Page 19. This table
lists the additional venting components needed
(in addition to the termination and adapter) for
a particular range of wall thicknesses.
K. Attach termination adapter - Attach the
adapter (SV4.5RCH - provided with the termi
-
nation) to the vent section or telescoping vent
section), elbow or appliance collar as shown
in
Figure 27 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), 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
27, 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. 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 28.
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 sur-
faces, we recommend the use of
a Termination Guard. This can be
purchased at your local dealer.
