Finishing
A. Facing and Finishing Instructions
WARNING! Risk of Fire!
Comply with all minimum clear-
ances to combustibles as speci
fi
ed. Framing closer than the
minimums listed must be constructed entirely of noncom-
bustible materials (i.e., steel studs, concrete board, etc.).
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
RED40 and RED40ST models. Splatter guards must
be removed before 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 speci
fi
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
may cause
fi
re.
Non-Combustible Materials Speci
fi
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! DO NOT
use screws longer
than two inches when attaching
fi
nishing materials to
non-combustible material. Screws longer than two inches
will compromise clearance and may cause overheating
and
fi
re.
CAUTION! Risk of Glass Damage and Cuts!
DO NOT
drill or install any type of screw or fastener into the lower
cover panel. Sharp screw or fastener tips may penetrate
and break the glass or cause cuts.
The RED40 comes standard with a mesh front. The
fi
nal
fi
replace installation can be accomplished by either the
“overlap” or “inside-
fi
t” method. This section discusses
installation details associated with the Inside and Overlap
Fit methods.
If the
fi
nal
fi
replace installation uses the Overlap Method,
wall sheathing material 1/2 in thick is speci
fi
ed and can
be installed tight to the side
fi
nishing
fl
anges and factory-
supplied non-combustible board. If the
fi
nal
fi
replace
installation uses the Inside-Fit Method, additional
clearance must be maintained between combustible 1/2
in. thick wall sheathing material and the side
fi
nishing
fl
anges. This section discusses installation details
associated with the Inside and Overlap Fit methods and
speci
fi
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. Do not drill or install screws
which may penetrate the lower cover panel as this will
restrict required access to the glass and lower control
chamber. See Figure 10.1.
The appliance is designed to mate with 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. This section discusses
installation details associated with the Inside an Overlap
Fit methods.
Verify that the lower cover panel is installed correctly, and
that there are no screws used to attach drywall to the panel.
WARNING! Risk of Fire!
Maintain speci
fi
ed air space
clearances to combustibles.
Inadequate air space may cause overheating and
fi
re.
Ensure that the one inch back clearance and one inch
side clearances are maintained
