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-resis-
tant 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.
The appliance is designed to mate with 1/2 in. wall
sheathing materials such as drywall, plywood, wood
composites, or non-combustible materials.
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 installed
non-combustible board. Overlapping materials could
ignite.

To Reduce the Risk of Sheetrock Cracking:
DO
Use all purpose joint
compound.
Use eggshell paint
(100% acrylic latex paint, gloss or semi-gloss).
To Avoid Sheetrock Cracking:
DO NOT
Use a quick set or light weight joint compound.
Use fl at paint.
In extreme cases, lab tests have shown yellow pigments
fading out of paints over time due to heat. Vent run and
installation location will have an effect on wall temperature
and fading. If fading occurs, consider avoiding paint that
contains yellow pigment.
In regards to the sheetrock mud, apply a smooth, even
layer, covering a wide area of the wall for the best results.
For best results, follow the tips below.
WARNING! Risk of Fire! DO NOT use screws longer
than two inches when attaching fi nishing materials to in-
stalled non-combustible material. Screws longer than two
inches will compromise clearance and could cause over-
heating and fi re.
WARNING! Risk of Fire, Explosion or Asphyxiation!
DO NOT use screws more than 3/4 of an inch long on
lower cover panel. Longer screws may penetrate gas line
or damage valve or electrical components.
