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 specified in this manual. Ma-
terials overlapping into non-combustible zones could
ignite and will interfere with air flow through decora-
tive barrier fronts.
• Metal front of appliance may be covered with non-
combustible materials only.
• Facing and/or finishing materials must not interfere
with air flow 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 finished wall and appliance
top and sides using a 300 ºF minimum sealant. Refer
to Figure 10.1.
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.
If using vinyl flooring, refer to Section 3.E.

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.).
Splatter Guard
The splatter guard is a piece of corrugated mate-
rial used to protect the appliance during the installa-
tion process before finishing work on the whole hearth
is complete. A splatter guard is factory-installed on
CRAVE-C models. Splatter guards must be removed
before appliance is fired.
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 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-
included non-combustible material.
WARNING! Risk of Fire! Factory-included non-combus-
tible board MUST be installed. DO NOT remove or cover
it with combustible material, such as:
• Drywall (gypsum board)
• Plywood
• Materials that do not meet the ASTM E 136 Non-com-
bustibility standard (below).
Removal of installed, non-combustible board and/or use
of materials not meeting the ASTM E 136 standard could
cause fire.
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.
WARNING! Risk of Fire! Maintain specified air space
clearances to combustibles. Inadequate air space could
cause overheating and fire.
Finishing Materials
NOTICE: The maximum finishing material not only includes
the decorative finish materials (marble, tile, slate, etc) but
also the thin set, lath, and adhesive used to attach the
decorative finish material.
NOTICE: Hearth & Home Technologies recommends
using multiple pieces of decorative finish material around
the opening of the appliance to reduce the chances of
the material cracking. A single piece of decorative finish
material (such as marble or granite) is more susceptible
to cracking due to uneven heating and cooling which
causes temperature differentials within the material itself.
The use of multiple pieces will reduce the temperature
differentials in each piece and reduce the likelihood of
cracks. In addition to using multiple pieces of decorative
finish material, the installation of the Passive Heat optional
heat management system will also reduce the chances of
cracking.
