(305 mm) vertical run.
Combustible Walls (Fig. 15): Cut a 10³⁄₈"H x 9³⁄₈" W
(264 x 240 mm) hole through the exterior wall and
frame as shown.
Noncombustible Walls (Fig. 15): Hole opening must
be 7¹⁄₂" (190mm) in diameter.

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. 17)
STEP 4
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 18)
STEP 5
Guide the vent termination 4" collar into the 4" pipe then
the 7" collar into the 7" pipe. Do not force the venting
into position. If the pipes do not line up with the termi-
nation collars, disassemble pipes and reattach to the
fireplace collar. (Fig. 18)
STEP 6
Secure fireplace to floor through floor holes and adjust-
able frame drywall strip (nailing flange) to frame. (Refer
to Framing & Finishing Section).
