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.

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
located relative to the exterior surface to which
the termination is to be attached as shown in
Figure 36 and Table 8 on Page 21.
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
36, refer to Table 8 on Page 21. 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 (adapter - SV4.5RCH - provided with the
termination) to the vent section or telescoping
vent section), elbow or appliance collar as shown
in Figures 35 and 36 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 a
Firestop/Spacer (SV4.5HF) 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 35, and nail into place. The
Firestop/Spacer may also be installed over the
opening at the interior side of framing.
M. 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 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
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 36.
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. To prevent contact with hot
surfaces, we recommend the use of a
Termination Guard. See Page 33. This
can be purchased at your local dealer.
