Installation
Figure 13.
Retracted Installation using a combination of solid and flex
venting. Use the vent graph to determine your allowable
run, then select appropriate components.

B. Vertical (Through-The-Roof) Installations
5/8" with option for 4/7" (on applicable models)
Vertical rise >12' can be reduced (on applicable models).
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:
32 feet above fireplace.
35 feet above fireplace.
35 feet above fireplace.
Note: Flame characteristics will change if the maximum vent height
is used.
Minimum clearances 2" from vent to all combustible materials must
be maintained.

A maximum of two offsets
(each offset has two 90° bends)
may be
made and shall not exceed total length of 25% of the vertical vent
height, when measured center to center of piping.
Example:
Typical vent installation.
20' vertical vent
2 - 2' offsets required
25% of 20' = 5' max. offset allowed
This venting configuration meets requirements.
