Vertical Sidewall Installation

Step 1
Locate the vent opening on the wall. It may be neces-
sary to first position the fireplace and measure to
obtain hole location. Depending on whether the wall is
combustible or noncombustible, cut opening to correct
size. (Fig. 14) For combustible walls, first frame in
opening.
Combustible Walls: Cut a 9³⁄₈" x 9³⁄₈" (240mm x
240mm) hole through the exterior wall and frame as
shown. (Fig. 14)
Noncombustible Walls: Hole opening must be 7¹⁄₂"
(190mm) in diameter.
