Finishing

A. Facing and Finishing Instructions
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.).
Splatter Guard
The splatter guard is a piece of corrugated mate-
rial used to protect the appliance during the installa-
tion process before fi nishing work on the whole hearth
is complete. A splatter guard is factory-installed on
CRAVE models. Splatter guards must be removed be-
fore appliance is fi red.
WARNING! Risk of Fire! Remove the splatter guard be-
fore lighting the appliance. Shut off gas to the appliance
when the splatter guard is in place to prevent accidental
operation.
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-in-
stalled 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
could cause fi re.
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.
WARNING! Risk of Fire! Maintain specifi ed air space
clearances to combustibles. Inadequate air space could
cause overheating and fi re.
Ensure that the one inch back clearance and one inch
side clearances are maintained.

Finishing Materials
NOTICE: This one inch maximum not only includes the
decorative fi nish materials (marble, tile, slate, etc) but also
the thin set, lath and adhesive used to attach the decorative
fi nish material.
WARNING! Risk of Fire! DO NOT use screws longer
than two inches when attaching fi nishing materials to
factory-installed non-combustible material. Screws lon-
ger than two inches will compromise clearance and could
cause overheating and fi re.
WARNING! Risk of Fire, Explosion or Asphyxiation!
DO NOT use screws more than one inch long on lower
cover panel. Longer screws may penetrate gas line or
damage valve or electrical components.
This section discusses installation details associated
with the Inside and Overlap Fit methods and specifi es
additional non-combustible materials required.
When fi nishing the wall around the fi replace, it is critical
that wall sheathing be fastened properly. Wall sheathing
fasteners, such as screws or nails, are not permitted in
some locations. See Figure 10.1.
It is acceptable to pre-drill holes and use self-tapped
screws in the factory-installed non-combustible board
which may be used to lathe (a backer for tile, marble,
etc.). Screws being installed through the factory-installed
non-combustible board should be self-tapping type with a
maximum length of 2 inches. See Figure 10.1.
When installing fi nish material on the lower cover panel,
DO NOT drill or install screws longer than one inch.
Screws longer than one inch could penetrate the lower
cover panel causing damage to components or penetrate
the gas line. One inch screws are included in the manual
bag assembly that are intended for use when attaching
fi nishing material to lower cover panel. See Figure 10.1.
