A maximum of two offsets
(each offset has two 90° bends)
may be made if
the length of the offsets does not exceed 25% of the vertical vent height, when
measured center to center of piping.
Using this vent installation example:
• 30' vertical vent
• 2 - 2' offsets required
Maximum offset allowed = 25% of 30'or 71/2'.
This venting configuration meets requirements.
