Vertical Vent Installations

Vertical Installations with a rise greater than 12' can be reduced

from 5/8 to 4/7 venting.

• 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 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 clear-

ance 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.

30' vertical vent

2 - 2' oﬀsets required

25% of 30' = 7-1/2' max. oﬀset allowed

This venting conﬁguration meets requirements.

1. Straight Vertical Installation

Figure 17. Straight, vertical venting. When the vent run is not

reduced use a PEL-90F/F elbow, which is connected
