Wall Sleeve Installation —
Thick Wall Construction
A heavy-gauge, corrosion resistant wall sleeve is provided
for each unit. The wall sleeve is either shipped in a separate
carton or shipped in a multi-pack of 15.
Typical installation for masonry walls is shown in Figure
13. The recommended installation procedure for this type
of construction is as follows:
1. Clean the opening of all debris that may interfere with
installation.
2. Be sure the unit’s center of gravity falls within the load
bearing surface of the wall. The center of gravity for
the unit is approximately 10
3
⁄
4
" (273mm) from the rear
edge of the wall sleeve. If the center of gravity is not
within the load bearing surface, then additional support
such as wood, metal or concrete must be provided in
the field.
3. Place a thin pad of soft mortar on the bottom of the
opening.
Important:
Make certain the wall sleeve
protrudes into the room a minimum of 1
1
⁄
8
" (29mm)
beyond the finished wall surface to accommodate the
heat section and room cabinet. Be sure to recess the wall
sleeve enough to accommodate outside louver. This
recess is 3/8" (9.5mm) for stamped louvers and 1
1
⁄
4
"
(32mm) for architectural louvers. The louver should
be flush to exterior surface when completed.
4. If a brickstop is employed (as shown in Figure 5), slide
the wall sleeve into the wall until the brickstop contacts
the exterior bricks, as illustrated below. If a brickstop
is not used, slide the wall sleeve in the wall so that
it extends into the room a minimum of 1
1
⁄
8
" (29mm)
beyond the finished interior wall surface. This allows
room to attach the heat section and room cabinet. The
wall sleeve should also be recessed enough to accom-
modate the outside louver. Level wall sleeve side to
side and pitch to outside 1/8"/ft. to assure proper sleeve
drainage to outside.
5. After the mortar has dried, remove the masonry sup-
port from the wall sleeve.
Note:
The wall sleeve is not
intended to replace the lintel.
6. Anchor with appropriate fasteners (as shown in Figure
15, page 12). A 5/16" (8mm) hole is provided on each
side, 2" (51mm) down from the top and 2" (51mm)
in from the rear of the wall sleeve. It may necessary
to drill additional holes in the wall sleeve to firmly
secure it.
CAUTION
Do not drill holes in the base of the wall sleeve. Use shims
between the wall and the wall sleeve to prevent wall sleeve
distortion during anchoring.
Notes:
1. For dimensions

and
D
, see table on page 6.
2. Dimension
“X”
is “as required” and is usually sent to the factory
to be welded during wall sleeve fabrication.
3. Caulk entire perimeter of wall sleeve after installation.
4. Wall sleeve to extend a minimum of 1-1/4" past finished
sheetrock.
5. Wall sleeve should be installed recessed 1-1/4" from face of brick
so that when louver is installed it is flush with face of building.

7. Caulk the wall sleeve to the wall opening on both the
in-side and outside perimeter using a resilient, non-
hardening caulk such as silicone. Be careful
not
to
plug the weep holes.
