range of exterior wall thicknesses.
HORIZONTAL VENT FIGURES/TABLES
NOTE:
Secure Vent
®
components (rigid vent pipe and terminal) are shown
in the figures;
Secure Flex
®
components (flexible vent pipe and terminal)
may also be used.
NOTE:
SV4.5VF (Secure Vent), SF4.5VF (Secure Flex) firestop/spacer must
be used anytime vent pipe passes through a combustible floor or ceiling.
SV4.5HF (Secure Vent), SF4.5HF (Secure Flex) firestop/spacer must be used
anytime vent pipe passes through a combustible wall.
NOTE:
Two 45 degree elbows may be used in place of one 90 degree elbow.
The same rise to run ratios, as shown in the venting figures for 90 elbows,
must be followed if 45 degree elbows are used.
NOTE:
It is very important that the horizontal/inclined run be maintained in
a straight (no dips) and recommended to be in a slightly elevated plane, in
a direction away from the fireplace of 1/4" rise per foot (20 mm per meter)
which is ideal, though rise per foot run ratios that are smaller are acceptable
all the way down to at or near level.

field shortening of the termination collar and adaptor may be required.

**NOTE:
To prevent water infiltration in wet
environments, we recommend the use of a
silicone sealant between the termination and
the wall. (Refer to

WARNING
Under no circumstances, may separate sections of con-
centric flexible vent pipe be joined together.
M. Install the desired termination -
1. Install the short square termination
(SV4.5HTSS) -
For the last step , from outside
the exterior wall, slide the collars of the ter-
mination into the adaptor
(see
Figure 4
)
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.
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 5
.
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 4
.
2. Install the square termination (SV4.5HTSS)
-
For the last step , from outside the exterior wall,
slide the collars of the termination onto the last
vent section
(see
Figure 5
)
until the termination
seats against the exterior wall surface to which
it will be attached.
