SV4.5HF (Secure Vent), SF4.5HF (Secure Flex) firestop/spacer must be used anytime vent pipe passes through a combustible wall. • 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. • AN ELBOW IS ACCEPTABLE AS 1 FOOT OF VERTICAL RISE EXCEPT WHERE AN ELBOW IS THE ONLY VERTICAL COMPONENT IN THE SYSTEM (See Figure 37). WARNING Under no circumstances, may separate sections of concentric flexible vent pipe be joined together.

Example: If 20 feet total (H+H1) horizontal vent run is needed, then 4 feet minimum of (V) vertical vent will be required. vertical, you are allowed 5 feet of (H+H1) horizontal run up to a maximum total horizontal run of 20 feet. Example: If 20 feet total (H+H1) horizontal vent run is needed, then 4 feet minimum of (V) vertical vent will be required. This table shows a 1(V) to 5(H) ratio. For every 1 foot of (V) vertical, you are allowed 5 feet of (H+H1) horizontal run up to a maximum total horizontal run of 20 feet. An elbow is acceptable as 1 foot of vertical rise except where an elbow is the only vertical component in the system. See Figure 37.
