Clearance Requirements
The top, back, and sides of the fireplace are defined by
stand-offs. The minimum clearance to a perpendicular wall
extending past the face of the fireplace is one inch (25 mm).
The back of the fireplace may be recessed 21 1/2 inches
(546 mm) into combustible construction.
NOTE: When venting with a 90
0
elbow as the first vent
component, an area 3 above the horizontal vent, the
entire width and depth of the firebox must be free of
combustibles. (See Figure 3)
Framing should be
constructed of 2 X 4
lumber or heavier.

Framing
Dimensions
For minimum clearances, see the direct vent termination
clearance diagrams on pages 20 and 21 in this manual.
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.
Step 2. Framing the Fireplace
Fireplace framing can be built before or after the fireplace is
set in place. Framing should be positioned to accommo-
date wall coverings and fireplace facing material. The dia-
gram below shows framing reference dimensions.
CAUTION:
MEASURE FIREPLACE DIMENSIONS AND
VERIFY FRAMING METHODS AND WALL COVERING
DETAILS BEFORE FRAMING.
