Rear Wall Vent Installation -
Flex Vent Pipe
Follow Steps 1 and 2 on Page 13.
Step 3
Install the 4” (102 mm) flex vent pipe to the appliance
collars described in “General Information Assembling
Vent Pipes”, Page 12. If the installation requires a 45°
angle, grasp the vent pipe close to the appliance collar
and bend to 45°. DO NOT exceed 45°. (Fig. 18)
Install the 7” vent pipe in the same manner as Step 2.

Since it is very important that the vent-
ing system maintain its balance between
the combustion air intake and the flue
gas exhaust, certain limitations as to vent
configurations apply and must be strictly
adhered to.

When vent termination exits through foundations less
than 20” (508 mm ) below siding outcrop, the vent pipe
must flush up with the siding. It is always best to locate
the fireplace in such a way that minimizes the number
of offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the flue collar of the fireplace to the face of
the outer wall.
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.

If a 90° elbow is used in the horizontal vent run
(level height maintained) the maximum horizontal
vent length is reduced by 36” (914 mm). (Fig. 21)
This does not apply if the 90° elbows are used to
increase or redirect a vertical rise. (Fig. 22)

Example: According to the chart the maximum hori-
zontal vent length in a system with a 7.5’ (2.3 m) verti-
cal rise is 20’ (6 m) and if a 90° elbow is required in
the horizontal vent it must be reduced to 17’ (5.2 m).
In Figure 21 Dimension A plus B must not be greater
than 17’ (5.2 m).
