Installation
Vertical Vent Installations
Vertical Terminations must be installed:
•
minimum 2' (two feet) above the highest point where
vent passes through the roof.
•
minimum 6' (six feet) from a mechanical air inlet
•
minimum 18" (1 1/2 feet) from a parapet wall.
Maximum vent height is 30 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 if the length of the offsets does not exceed 25% of the
vertical vent height, when measured center to center of piping.
Example:
Typical vent installation.
30' vertical vent
2 - 2' offsets required
25% of 30' = 7-1/2' max. offset allowed
This venting configuration meets requirements.
