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: 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.

WARNING: UNDER NO CIRCUM- STANCES MAY SEPARATE SECTIONS OF CONCENTRIC FLEXIBLE VENT PIPE BE JOINED TOGETHER.

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.
