 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".

2. Offset Vertical Installations

A maximum oftwo 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.
