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. 43)
For combustible walls first frame in opening.
Combustible Walls:
(Fig. 43) Cut a 9³⁄₈”H x 9³⁄₈”W (240
x 240 mm) hole through the exterior wall and frame as
shown.
Noncombustible Walls:
(Fig. 43) Hole opening must
be 7¹⁄₂” (190 mm) in diameter.
