Installation Of Vertical Vent DV
n 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.
n Maximum vent height is 30 feet above fireplace.
Note: Flame characteristics will change if the maximum vent height
is used.
n Minimum clearances 2" from vent to all combustible materials must
be maintained.
n 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
