IMPORTANT
The vent termination is hot while
in operation and for a period of
time following the use of the fi re-
place. To prevent contact with hot
surfaces, we recommend the use
of a Termination Guard. See Items
12 and 13 on Page 31. This can be
purchased at your local dealer.
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 end of the last section is
within 5 in. (127 mm) to 9-1/4 in. (235 mm)
inboard of the exterior surface to which the
SV4.5HT-2 termination is to be attached, see
Figure 34. If the end of the last section is not
within this distance, use the telescopic vent sec-
tion SV4.5LA, as the last vent section. For wall
thicknesses greater than that shown in Figure
34, refer to Table 11 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 (SV4.5RCH - provided with the termi-
nation) to the vent section or telescoping vent
section), elbow or appliance collar as shown
in Figures 33 & 34 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
33, 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 (SV4.5HT-2)
Install the square termination - 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 34.

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 roofl ines may create a heavy fl ow 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.
