STEP 1
Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 31) (For
combustible walls first frame in opening.)
NOTE: When using flex vent, the opening will have to
be measured according to the 1/2” (13 mm) rise in 12”
(305 mm) vent run.
Combustible Walls
(Fig. 31): Cut a 9³⁄₈”H x 9³⁄₈” W
(240 x 240 mm) hole through the exterior wall and
frame.
Noncombustible Walls
(Fig. 31): Hole opening must
be 7.5” (190 mm) in diameter.

Firestop
STEP 2
Measure wall thickness and cut adjustable zero clearance
sleeve parts to proper length (MAXIMUM 12”/305 mm).
Assemble sleeve and attach to firestop with #8 sheet metal
screws (supplied). Install firestop assembly. (Fig. 32)
Zero clearance sleeve is only required for
combustible walls.
STEP 3
Place fireplace into position. Measure the vertical height
(X) required from the base of the flue collars to the
center of the wall opening. (Fig. 33)
STEP 4
Apply a band of silicone to the inner and outer flue
collars of the fireplace and using appropriate length of
pipe section(s) attach to fireplace with three (3) screws.
Follow with the installation of the inner and outer elbow,
again secure joints with three (3) sheet metal screws.
Wipe off any excess silicone.
STEP 5
Measure the horizontal length requirement including a
2” (51 mm) overlap, i.e. from the elbow to the outside
wall finish plus 2”, or the distance required if installing a
second 90° elbow. (Fig. 24)
Always install horizontal venting on a level
plane.
STEP 6
Use appropriate length of pipe section - telescopic or
fixed - and install. The sections which go through the
wall are packaged with the starter kit, and can be cut to
suit if necessary.
Sealing vent pipe and firestop gaps with high tem
-
perature sealant will restrict cold air being drawn in
around fireplace.
