NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
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 and Figure 29. 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 30 and Table 9.
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
30, refer to Table 9 on Page 20. 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 (SV4.5RCH - provided with the termi-
nation) to the vent section or telescoping vent
section), elbow or appliance collar as shown in
Figure 29 in the same manner as any SV4.5
vent component (refer to Step E).
L. Install Firestop/Spacer at exterior wall -
When using the 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 29, and nail into place.
(The Firestop/Spacer may also be installed over
the opening at the interior side of framing).
M. Install the Termination (SV4.5HT-2)
For the last step, from outside the exterior
wall, slide the collars of the termination onto
the adaptor (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 30.
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 surfaces,
we recommend the use of a Termina-
tion Guard. See Page 36. This can be
purchased at your local dealer.
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.
