Wall Sleeve Installation

Wall Opening Requirements

Before installing the unit, check the wall opening to be sure the
wall sleeve will slide into the opening unobstructed. For masonry
walls, a lintel must be used to provide support over each opening.

Figures 3 through 5 on the following pages illustrate typical wall
sleeve installations. After the wall sleeve has been set in place
anchor it in the opening as shown in Figure 2. It is recommended
that rubber isolation washers be used with the fasteners to mini­mize sound transmission from the equipment to the wall, at the
point of contact.

Wall Sleeve Installation — Thin Wall Construction

Applications utilizing field supplied louvers require additional
considerations:

Assuming the louver meets the manufacturer’ s criteria, as stated
previously, proceed to install the wall sleeve as follows:

1. Louvers supplied by others must have 70% free area or a
pressure drop not exceeding 0.05 in. w.g. at 300 fpm face

2. Position the wall sleeve into the w all so that it is flush with the
exterior wall. Important: If the wall sleeve has been installed

Installation of wall sleeves with continuous louvers is very

similar to that of applications with factory furnished louvers.

and outside perimeter. This can be done from the inside of
the building. Be careful not to plug the weep holes.

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 5.
The recommended installation procedure for this type of
construction is as follows:

1. Clean the opening of all debris that may interfere with instal-

lation.

2. Be sure the unit’s center of gravity falls within the load

bearing surface of the wall. The center of gr avity f or the unit is

3

approximately 10

/4" 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

1

room a minimum of 1

/8" 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" for stamped louvers and 11/4" for archi­tectural louvers. The louver should be flush to e xterior surface
when completed.

4. If a brickstop is employed (as shown in Figure 5), slide the
wall sleeve into the wall until the br ickstop 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

1

room a minimum of 1

/8" 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 suport 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 appropriate

5

fasteners (as shown in Figure 2, page 1). A

/16" hole is pro­vided on each side, 2" down from the top and 2” in from the
rear of the wall sleeve. It may be 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 inside
and outside perimeter using a resilient, non-hardening caulk
such as silicone. Be careful not to plug the weep holes.
