Painting
If desired 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 replace 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 nish the drywall. If a crack
does emerge adjacent to the replace, it can be perma-
nently repaired by 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.
Wall Extension
Wall extension must be sealed to existing masonry wall.
See Figure 3.11. Framing studs may not sit ush against
existing masonry wall. In order to keep heat from escap-
ing behind the wall this transition must be sealed.
• Seal with a high temperature silicone 300 °F.
and / or
• Packing insulation into voids between the masonry wall
and steel studs is acceptable.
Note: Combustible materials may be used to seal wall
extension to existing masonry wall as long as it is out-
side the non-combustible zone.
NOTE: Concealed sections of 3 in. ex pipe must
be contained inside existing masonary replace
ue vent or installed into an existing wood burn-
ing vent system.
