Installing the Fireplace
Step 1. Locating the Fireplace
The diagram below shows space and clearance require-
ments for locating a fireplace within a room.

Figure 3. Fireplace Dimensions, Locations,
and Space Requirements
Clearance Requirements
The top and back of the fireplace are defined by stand-offs.
The minimum clearance to a perpendicular wall extending
past the face of the fireplace is 3 inches (76mm). The back
of the fireplace may be recessed 16 1/4 inches (413mm)
into combustible construction.
Minimum Clearances
from the Fireplace to Combustible Materials
Glass Front ........................ 36 .................... 914
Floor ................................... 0 ....................... 0
Rear ................................... 1/2 ..................... 13
Sides ................................. 1/2 ..................... 13
Top ................................... 1 1/2 ................... 38
Ceiling* .............................. 31 .................... 787
* The clearance to the ceiling is measured from the top
of the unit, excluding the standoffs (see Figure 36).
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.

For minimum clearances, see the direct vent termination
clearance diagrams on pages 26 and 27 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.
VENT
FRAMING
HOLE
Framing should be
constructed of 2 X 4
lumber or heavier.
The framing headers
may rest on the
fireplace stand-offs.
WARNING:
To ensure proper clearances
the front framing header must
be installed on its narrow edge
and to the front of the frame.
