Finishing

A. Facing Materials
WARNING! Risk of Fire! Comply with all minimum clear-
ances to combustibles as specified. Framing closer than the
minimums listed must be constructed entirely of noncom-
bustible materials (i.e., steel studs, concrete board, etc.)
The appliance is designed to accept 1/2 in. wall sheathing
materials such as drywall, plywood, wood composites, or
non-combustible materials. The type of material used
depends whether the installation is an Inside or Overlap
Fit Method. Refer to Section 10.D regarding installation
details associated with the Inside and Overlap Fit
methods.
The factory-supplied non-combustible board must be
used in all installations. It must be directly attached to
structural framing adjacent to the appliance. Screw fas-
teners should be installed in the pilot holes provided in
the outer perimeter of the non-combustible board. See
Figure 10.1 and Figure 10.2.
The factory-supplied board is designed such that its edg-
es will be at the approximate center of the adjacent fram-
ing, assuming it is 1-1/2 in. nominal thickness. This will
allow the wallboard joints to occur on the center of the
framing where the panels can be fastened properly. If the
framing thickness is less than 1-1/2 in. nominal, such as
with formed steel systems, then it may be necessary to
adjust the adjacent framing dimensions so that the non-
combustible board and wallboard joints are centered on
the framing.
Finishing Instructions
It is important to follow the framing and finishing instruc-
tions to ensure proper placement of fireplace into the sur-
rounding framing/finishing materials.
Wall sheathing materials 1/2 in. thick are specified in
this installation manual to properly align with the factory-
installed non-combustible material.
WARNING! Risk of Fire! DO NOT remove the factory-
installed non-combustible board or cover it with combus-
tible material, such as:
• Drywall (gypsum board)
• Plywood
• Materials that do not meet the ASTM E 136 Non-com-
bustibility standard (below).
Removal of factory-installed, non-combustible board and/
or use of materials not meeting the ASTM E 136 standard
may cause fire.
• Facing and/or finishing materials must not interfere with
air flow through decorative fronts.
• Facing and/or finishing materials must never overhang
into the glass opening.

• Observe all clearances when applying combustible
materials.
WARNING! Risk of Fire! DO NOT apply combustible
materials beyond the minimum clearances. Comply with
all minimum clearances to combustibles as specified in
this manual. Overlapping materials could ignite and will
interfere with proper operation of decorative fronts.
WARNING! Risk of Fire! DO NOT install drywall or other
combustible materials over the factory-installed non-com-
bustible board. Overlapping materials could ignite.
Decorative facing material thickness is measured from
the face of the factory-installed non-combustible board.
See Section 10.D for Overlap Fit and Inside Fit require-
ments.
Non-Combustible Materials Specification
Material which will not ignite and burn. Such materials are
those consisting entirely of steel, iron, brick, tile, concrete,
slate, glass or plasters, or any combination thereof.
Materials that are reported as passing ASTM E 136,
Standard Test Method for Behavior of Materials in a
Vertical Tube Furnace at 750 ºC.
