Drywall Joint-Crack Prevention and Repair
Drywall joints around the fireplace will be affected by ex-
posure to elevated temperatures, along with other envi-
ronmental, structural factors due to new construction, and
methods used to install and finish the drywall. If a crack
does emerge adjacent to the fireplace, it can be perma-
nently repaired by filling 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.
WARNING! Risk of Fire! Maintain specified air space
clearances to combustibles. Inadequate air space could
cause overheating and fire.
WARNING! Risk of Fire! Maintain specified air space
clearances to combustibles. Failure to comply with
these instructions may cause a fire or cause the appli-
ance to overheat.
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.
