See

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: 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.
Square termination (SV4.5HTS)
shown; Round Termination
(SV4.5HTR) may also be used.
Small Square termination
(SV4.5HTSS) may only be used
on DT-500 and D-500 models.
WARNING: UNDER NO CIRCUM-
STANCES MAY SEPARATE SECTIONS
OF CONCENTRIC FLEXIBLE VENT
PIPE BE JOINED TOGETHER.
Round Termination (SV4.5HTR) may not be used.
Round Termination (SV4.5HTR) may not be used.

(SV4.5HTSS) may only be used

See
Table 3 as an aid in venting component selection for a particular
range of exterior wall thicknesses.
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 (Se-
cure Flex) firestop/spacer must be used anytime
vent pipe passes through a combustible wall.
