Installation
Figure 12. Extended Installation using a combination of solid and ex
venting. Use the vent graph to determine your allowable
run, then select appropriate components.

(see Figure 12 and 13).

one another to obtain different possible horizontal length installations.
NOTE: Flex section with no vertical rise must not exceed maximum
horizontal length of 3 feet (see Figure 14). Flex runs over 3 feet must
fall within the limits set by the venting graph, and must have a minimum
verticalriseof3"perfootofex.

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:
• 35feetabovereplace.
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
4’ max.
