- 6" to 9-1/4" Wall Thickness, SV4.5HTSS Terminations
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 up to 15-
3/4" (400mm). For distance greater than 15-1/4"
(400mm) use adaptor SV4.5RCHA and refer to
Table 1
. This table lists venting components
needed in addition to the termination adaptor.
Also refer to the vent section length chart in
the fireplace installation instructions manual
for help on selecting additional vent sections.
Square Horizontal Termination -
(Kit No. SV4.5-20SSWSK)
Assemble the venting system to a point where
the terminus of the last section is within 6"
(152mm) to 21-1/4" (540mm) inboard of the
exterior surface to which the termination is
to be attached, see
Figure 5
. Attach Adaptor
SV4.5RCHA as shown in
Figure 3
. Go to
Step
K
for cutting to length instructions.

Attach Termination Adaptor -
Square Horizontal Termination Kit SV4.5HTSS
(with short adaptor)
Attach adaptor
SV4.5RCH
(provided with the
termination kit), to the vent section or telescop-
ing vent section, elbow or appliance collar as
shown in
Figure 3
, in the same manner as any
SV4.5 vent component (refer to
Step E
).
Square Horizontal Termination Kit
SV4.5-20SSWSK (with short adaptor)
Attach adaptor
SV4.5RCHA
(provided with the
termination kit No. SV4.5-20SSWSK), to the
vent section or telescoping vent section, elbow
or appliance collar as shown in
Figure 3
, in
the same manner as any SV4.5 vent component
(refer to
Step E
).
d)
Proceed to mark the inner pipe using the
same dimension for the outer pipe, it is rec-
ommended to add 1/4" to the length to aid in
catching the mating pipe when inserting the
termination.

Install Firestop/Spacer at exterior wall
-
When using either of the
square
termina-
tions, install SV4.5HF (Secure Vent), or SF4.5HF
(Secure Flex) firestop/spacer over the opening
at the exterior side of the framing, long side up,
with the 3" spacer clearance at the top as shown
in
Figure 3
, and nail into place. (The Firestop/
Spacer may be installed over the opening at
the interior side of the framing).
It may be necessary to cut the excess length from
the adaptor. Measure the distance from the last
venting section to the exterior surface to which
the termination is to be attached, see
Figure 3
.
This is the total length the adaptor must be.
a)
Separate the inner and outer pipes from
the adaptor.
b)
Mark the desired length of the outer pipe
measured from the dimpled end towards the
plain end.
c)
Cut the excess material with sheet metal
scissors or similar tool.
