Verify that the lower cover panel is installed correctly,
and that there are no screws used to attach drywall to
the panel.

Note: It is acceptable to use a high temperature silicone
sealant to adhere drywall to lower cover panel.
Finish and Sealing Joints
All joints between the fi nished wall sheathing and the ap-
pliance must be sealed with non-combustible materials.
Sealants, such as caulk or mastic used to seal the gap
between the wall and the fi replace, should be rated at a
minimum continuous exposure to 300ºF.
Finishing Around Opening with Gypsum Wallboard
Gypsum wallboard (drywall) joints adjacent to the fi re-
place opening, including the non-combustible board on
the appliance, require special attention to minimize crack-
ing. When installing gypsum wallboard around the fi re-
place, install the hole for the fi replace opening in a single
wallboard sheet, if possible. This will minimize the joints
adjacent to the fi replace opening.
Tape wall board joints around the fi replace opening with
fi berglass-mesh tape. It will provide a more crack-re-
sistant joint than paper tape. Fill, smooth and fi nish wall
joints with chemically setting-type joint compound. It will
provide a more crack-resistant joint than air-drying light-
weight compound.
Painting
If desired fi nishing includes a painted wall, 100% acrylic
latex with compatible primer is recommended around this
appliance. Oil-based or standard acrylic paints may dis-
color due to heat exposure.

Facing Material
• Facing and/or fi nishing materials must not interfere with
air fl ow through louvers, operation of louvers or doors,
or access for service.
• Facing and/or fi nishing materials must never overhang

WARNING! Risk of Fire! DO NOT apply combustible
materials beyond the minimum clearances. Comply with
all minimum clearances to combustibles as specifi ed in
this manual. Overlapping materials could ignite and will
interfere with proper operation of doors and louvers.
WARNING! Risk of Fire! DO NOT install drywall or
other combustible materials directly onto the factory-
installed non-combustible board. Overlapping materials
could ignite.
Decorative facing material thickness is measured from
the face of the factory-installed non-combustible board.
See Figure 10.2.
The mesh front can be installed such that it overlaps non-
combustible materials up to 1-1/4 in. thick. See Figure 10.3.
Refer to Section 1.E and 1.F of this manual for defi nition
