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 5.
The recommended installation procedure for this type of con-
struction 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 open-ing.
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

" (9.5mm) for stamped
louvers and 1

" (32mm) for architectural louvers. The louver
should be flush to exterior surface when completed.
Wall Sleeve Installation — Thick Wall Construction
Figure 5. Wall sleeve installation using brickstops
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 accommodate the outside louver.
5. After the mortar has dried, remove the masonry support from
the wall sleeve. Note: The wall sleeve is not intended to
replace the lintel.
6. Level wall sleeve in all directions and anchor with appropri-
ate fasteners (as shown in Figure 23, page 11). A

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.
7. Caulk the wall sleeve to the wall opening on both the
in-side and outside perimeter using a resilient, nonhardening
caulk such as silicone. Be careful not to plug the weep holes.
Notes:
1. For dimensions B and D, see table on page 3.
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.
