Vertical Vent Installations
Vertical vent Installations.
• 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" (1½ feet) from a parapet wall.
 Maximum vent height is 32 feet above replace.
Note: Flame characteristics will change if the maximum vent height is used.
 Minimum clearance to combustible construction around the vent pipe
is 1" on all sides must be maintained, except on horizontal venting where the
top of the pipe must have a clearance of at least 2".
2. Oset Vertical Installations
A maximum of two osets (each oset has two 90° bends) may be made if
the length of the osets does not exceed 25% of the vertical vent height, when
measured center to center of piping.
Example: Typical vent installation.
32' vertical vent
2 - 2' osets required
25% of 30' = 7½' maximum oset allowed
This venting conguration meets requirements.
