WARNING! Risk of Fire!
Maintain speci
fi
ed air space
clearances to combustibles.
Failure to comply with
these instructions may cause a
fi
re or cause the appli-
ance to overheat.
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.
Note: It is acceptable to use a silicone sealant with
a minimum of 300 ºF continuous exposure rating to
adhere drywall to lower cover panel.
The
fi
nal
fi
replace installation can be accomplished by
either the Overlap Fit or Inside Fit method. Reference
Section 10.D regarding installation details associated
with the Inside Fit and Overlap Fit methods.
It is acceptable to pre-drill holes and use self-tapping
screws in the installed non-combustible board to attach
non-combustible backer board for tile, marble, etc. Refer
to Figure 10.2 for acceptable screw or metal lath location
and screw length requirements.
Do not drill or install screws which may penetrate the
lower cover panel as this will restrict required access
to the glass, battery-backup, and control module. See
Figure 10.2.
Note:
If the desired look is painted drywall, it is
recommended that no additional screws are installed into
the factory-provided non-combustible board. Only install
the screws provided into the pilot holes located in the
factory-provided non-combustible board.

NOTICE:
The location of the Passive Heat discharge
opening could allow for venting and other construction
materials to be visible. It is acceptable to paint the vent pipe
and other construction materials using a high temperature
paint with a minimum of 300 °F continuous exposure rating.
Hearth & Home Technologies recommends using black
touch up paint (part number TUP-GBK-12) available from
your Hearth & Home Technologies dealer.
Painting
If desired
fi
nishing includes a painted wall, a high-quality
100% acrylic latex paint with a high-quality latex primer
base coat are recommended around the appliance to limit
discoloration. Oil-based or standard acrylic paints may
be more prone to discoloration due to heat exposure.
Drywall Joint-Crack Prevention and Repair
Drywall joints around the
fi
replace will be a
ff
ected by ex-
posure to elevated temperatures, along with other envi-
ronmental, structural factors due to new construction, and
methods used to install and
fi
nish the drywall. If a crack
does emerge adjacent to the
fi
replace, it can be perma-
nently repaired by
fi
lling it with a paintable latex caulk,
followed by repainting.
Some movement of the screws used to secure the non-
combustible board to the appliance/surround framing is
expected. If a blemish begins to show over a screw head,
sand the surface to remove the blemish and repaint.
