Masonry Construction
1. Cut or build a wall opening in the masonry
wall similar to the frame construction (refer to
Step 2 of Thru-the-WaU Installation for a wall
thickness greater than 8-1/2").
.
Secure cabinet in place using masonry nails, or
the right masonry anchor screws. (Another
way to do this is to build an in-between frame
of 2x4's (51 mm x 102 mm) as shown in the
Step 2 Prepare Wall illustrations-- but make it
double framed on either side, and install
between masonry wall opening and cabinet.
Frame must be securely anchored to masonry
wall opening.)This way gives very good
louver clearance on either side of cabinet.
3. Install a lintel to support masonry wall above
cabinet. Existing holes in cabinet can be used
and/or additional holes can be drilled to fasten
cabinet at various positions. Be sure that side
louver clearance is in accordance with Step 1
above.
4. Install exterior cabinet support brackets as
shown in Step 2 of Thru-the-Wall Installation.
Caulk or flash if needed, to provide a weather-
tight seal around top and sides of cabinet.
5. To complete installation, apply wood trim
molding around room side projection of
cabinet.
