* The clearance to the ceiling is measured from the
top of the unit, excluding the stand-offs and collar.
See Figure 24 for further details.
(Center of 12 x 10)
Clearance Requirements
The top, back, and sides of the fi replace are defi ned by
stand-offs. The minimum clearance to a perpendicular wall
extending past the face of the fi replace is 4 inches (102
mm). The back of the fi replace may be recessed 23 (584
mm) inches (546 mm) into combustible construction.
Step 2. Framing the Fireplace
Fireplace framing can be built before or after the fi replace is
set in place. Framing should be positioned to accommodate
wall coverings and fi replace facing material. The diagram
below shows framing reference dimensions.
CAUTION: MEASURE FIREPLACE DIMENSIONS, AND
VERIFY FRAMING METHODS AND WALL COVERING
DETAILS, BEFORE FRAMING.
The distance from the unit to combustible construction is
to be measured from the unit outer wrap surface to the
combustible construction, NOT from the screw heads
that secure the unit together.
