NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
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.

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 5 in. (127 mm) to 8-1/2 in. (216
mm) inboard of the exterior surface to which
the SV8HTS termination is to be attached, see
Figure 30 and Table 8.
If the terminus of the last section is not within
this distance, use the
telescopic vent section
SV8LA, as the last vent section. For wall thick-
nesses greater than that shown in Figure 30,
refer to Table 8 on Page 19. 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 - SV8RCH - provided with the
termination) to the vent section or telescoping
vent section), or elbow as shown in Figure 29
in the same manner as any SV vent component
(refer to Step E).
L. Install Firestop/Spacer at exterior wall
- When using the square termination, install
SV8HF 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 29, and nail into place.
(The Firestop/Spacer may also be installed
over the opening at the interior side of the
framing).
M. Install the square termination (SV8HTS)-
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 30.
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.
