Installation Of Vertical Vent DV

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 clearance to combustible construction around the

vent pipe is 1" on all sides must be maintained, except on hori-

zontal venting where the top of the pipe must have a clearance of

at least 2".

A maximum of two oﬀsets (each oset 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.
