mm) vertical run.

x 40 mm) hole through the exterior wall and frame as
shown.
Noncombustible Walls (Fig. 17): Hole opening must be
7¹⁄₂" (190 mm) in diameter.

STEP 3
Measure from the fireplace collar or elbow face to face
of outside wall (add " 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. 19)
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 0)
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 termination
collars, disassemble pipes and reattach to the fireplace
collar. (Fig. 1)
STEP 6
Secure fireplace to floor through floor holes and adjust-
able frame drywall strip (nailing flange) to frame. (Refer to
Framing & Finishing Section).
