Finishing

A. Facing Material
WARNING
Risk of Fire!
DO NOT apply combustible materials beyond the min-
imum clearances. Comply with all minimum clearanc-
es to combustibles as specifi ed in this manual. Ma-
terials overlapping into non-combustible zones could
ignite and will interfere with air fl ow through decorative
barrier fronts.
• Metal front of appliance may be covered with non-
combustible materials only.
• Facing and/or fi nishing materials must not interfere
with air fl ow through decorative barrier fronts, removal
of decorative barrier fronts or access for service.
• Facing and/or finishing materials must never
overhang into the glass opening.
• Observe all clearances when applying combustible
materials.
• Seal gaps between the fi nished wall and appliance
top and sides using a 300 ºF minimum sealant. Refer
to Figure 10.1 and Figure 10.2.
NOTICE: Surface temperatures around the appliance will
become warm while the appliance is in operation. Ensure
finishing materials used for all surfaces (floor, walls,
mantels, etc.) will withstand temperatures up to 190°F.
WARNING! Risk of Fire! Comply with all minimum clear-
ances to combustibles as specifi ed. 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
Heat & Glo • COSMO32-IFT-B, COSMO36-IFT-B, COSMO42-IFT-B Installation Manual • 2619-980 Rev. G • 7/20
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 fi nishing instruc-
tions to ensure proper placement of fi replace into the sur-
rounding framing/fi nishing materials.
Wall sheathing materials 1/2 in. thick are specifi ed 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-
combustibility standard (below).
Removal of factory-installed, non-combustible board and/
or use of materials not meeting the ASTM E 136 standard
may cause fi re.
• Facing and/or fi nishing materials must not interfere with
air fl ow through decorative barrier fronts.
• Facing and/or fi nishing 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 specifi ed in
this manual. Overlapping materials could ignite and will
interfere with proper operation of decorative barrier fronts.
WARNING! Risk of Fire! DO NOT install drywall or oth-
er combustible materials over 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 Section 10.D for Overlap Fit and Inside Fit require-
ments.
Non-Combustible Materials Specifi cation
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.
