Rear Wall Installations
STEP 1
Locate vent opening on the wall. To locate hole center
consult with appropriate fireplace dimensions, Page 4.
Frame as shown below.
Combustible Walls (Fig. 14): Cut a 10³⁄₈"H x 9³⁄₈" W
(264 x 240mm) hole through the exterior wall and
frame as shown.
Noncombustible Walls (Fig. 14): Hole opening must
be 7¹⁄₂" (190mm) in diameter.
STEP 2
Measure wall thickness and cut zero clearance sleeve
parts to proper length (MAXIMUM 12"/305mm). As-
semble sleeve and attach to firestop with #8 sheet
metal screws (supplied). (Fig. 15)
STEP 3
Measure from the fireplace collar or elbow face to face
of outside wall (add 2" for vent pipe overlap). Mark
pipes and cut to length. It is very important that the two
pipes are flush with the outside wall once the fireplace
is in its final location. (Fig. 16)

Slip 4" and 7" pipes onto respective flue collars. Make
sure to fix to the fireplace collar the 4" pipe with three
(3) screws before fixing the 7" pipe on the 7" collar.
Both pipes must be on a level plane. (Fig 17)
STEP 5
Guide the vent termination 4" collar into the 4" pipe
then the 7" collar into the 7" pipe. Do not force the

termination collars, disassemble pipes and reattach to
the fireplace collar. (Fig. 17)
