ments for locating a fireplace within a room.

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.
Framing should be
constructed of 2 X 4
lumber or heavier.

D. ......... 25 5/8
Figure 3. Framing Dimensions
For minimum clearances, see the direct vent termination
clearance diagrams on pages 19 and 20 in this manual.
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.

* The clearance to the ceiling is measured from the top
of the unit, excluding the standoffs (see Figure 28).

The center of the hole is one
inch (25.4mm) above the center
of the horizontal vent pipe.

The distance from the unit to combustible construction is to
be measured from the unit outer wrap surface to the com-
bustible construction, NOT from the screw heads that se-
cure the unit together.
