Horizontal terminations have been designed to perform in a wide range of weather
conditions. Our terminations meet or exceed industry standards.
When selecting the locations of your horizontal terminations, do not place the
termination where water from eaves and adjoining rooflines may create a heavy flow
of cascading 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.

Installing the Square Horizontal Termination (SV4.5HT-2)
O. Install the desired termination -
1. 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 over the outer and the inner
inside 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 28.
SVHRK Snorkel Cap –The snorkel cap is de-
signed to be fitted into a basement window box.
The SVHRK cap is for use with flex vent. The
vertical distance between the inlet and outlet of
the cap is 28 in. (711 mm). pipe.
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
28, refer to Table 3 on page 18. This table lists
the additional venting components needed (in
addition to the termination and adapter) for a
particular range of wall thicknesses.
M. Attach termination adapter - Attach the
adapter (SV4.5RCH - provided with the termi-
nation) to the vent section or telescoping vent
section), elbow as shown in
Figure 27 in the
same manner as any SV4.5 vent component
(refer to Step F).
N. Install Firestop/Spacer at exterior wall -
When using the square termination, install
the SV4.5HF (Secure Vent) or SF4.5HF (Se-
cure Flex) Firestop/Spacer over the open-
ing at the exterior side of the framing (long
side up) as shown in
Figure 27, and fasten
into place. Ensure 5" clearance is main-
tained by framing above the vent run for
MPLDV35/40/45 when center line of the
run is lower than 48" (12119 mm) above
the fireplace top wrapper surface.
(The Firestop/Spacer may also be installed
over the opening at the interior side of the
framing.)
IMPORTANT: The vent termination is
hot while in operation and for a period of
time following use of the fireplace. To
prevent contact with hot surfaces, we
recommend the use of a Termination
Guard. This can be purchased at your
local dealer.
Firestop/Spacer provided with the
termination shown on the exterior
side of the wall. It may also be
installed on the interior side.
