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 located relative to the exterior surface
to which the termination is to be attached as
shown in Figure 34.
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
35, refer to Table 8 on Page 22. 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
Figures 34 and 35 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
34, 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 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 35.
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 34. This
can be purchased at your local dealer.
See Figures 11 and 12 on Pages 10 and
11 for Min. Distance to Base of Appliance.

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 silicon caulking where required.
