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: 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 slightly elevated plane in a direction away from the
fireplace of ¹⁄₄ " rise per foot (20 mm per meter) of horizontal vent.
Note: SV4.5BF (Secure Vent), SF4.5BF (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.
WARNING:
UNDER NO CIRCUMSTANCES MAY SEPARATE SECTIONS OF
CONCENTRIC FLEXIBLE VENT PIPE BE JOINED TOGETHER.

*Note: See Figure 36 for wall thickness range reductions when using
SV4.5HTS termination.
Only the square termination (SV4.5HTS) may be used.
See Table 3 as an aid in venting component selection for a particular
range of exterior wall thicknesses.
