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 " 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.
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.
WARNING: UNDER NO CIRCUMSTANCES MAY SEPARATE
SECTIONS OF CONCENTRIC FLEXIBLE VENT PIPE BE JOINED
TOGETHER.
