Vertical Vent Figures/Tables
NOTE: If the parameters of your vent run fall outside the parameters described herein, consider installing the Power Vent Kit.
NOTE: Rise per foot run ratios are acceptable all the way to level. For best results, maintain the horizontal/inclined
run in a straight (no dips), slightly elevated plane of approximately 1/4" per 1 ft (20 mm per 1 m).
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 (2) 45° elbows may be used in place of one (1) 90° elbow. The same rise to run ratios, as shown in the
venting figures for 90° elbows, must be followed if 45° elbows are used.
NOTE: An elbow is acceptable as 1 ft of vertical rise, except where an elbow is the only vertical component in
the system.
Do NOT join separate sections of concentric flexible vent pipe.
