Maximum vent height is: 32 feet above fireplace.
Note: Flame characteristics will change if the maximum vent height
is used.
Minimum clearances 2" from vent to all combustible materials must
be maintained.
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.
