Note: Flame characteristics will change if the maximum vent height is
used.
A maximum of two offsets (each offset has two 90° bends) may be
made and shall not exceed total length of 25% of the vertical vent
height, when measured center to center of piping.
Example: Typical vent installation.
20' vertical vent
2 - 2' offsets required
25% of 20' = 5' max. offset allowed
This venting configuration meets requirements.
