Installation

Horizontal Venting

Figure 11. Typical Top Vent installation. The solid sections can be used in

various combinations to obtain the desired vent run. The vent

run must fall within the limits set by the venting graph.

Figure 12. Extended Installation using a combination of solid and ﬂex

venting. Use the vent graph to determine your allowable

run, then select appropriate components.

90° Elbow

PEXT Section

Termination

Example 2:

Rigid sections and an elbow used in conjunction with 3 ft. ex section

(PFL-3) will, when extended in a ve foot chase, allow for a maximum

horizontal run of twelve and one-half feet from the centre of the replace

to outside wall and a minimum of 7'6" when retracted in opposite direction

(see Figure 12 and 13).

"C" ex sections and "D" rigid sections may be used in conjunction with

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.

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:

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.
