Wall Sleeve Installation
Thin Wall Construction
The standard wall sleeve is designed to be easily installed
in a variety of wall constructions. For panel wall and thin
wall construction, it is recommended that the optional top
angle be used and the wall sleeve be supplied with a turned
down ange (see Figures 9, 10 & 11).
The recommended procedure for installing units in panel
wall and thin wall construction is as follows:
1. Clean the opening of all debris that may interfere with
installation.
2. Recess the wall opening so that the louver is ush with
the exterior of the building. The center of gravity is ap-
proximately 10

⁄

" (273mm) from the rear face of the
standard wall sleeve. If a subbase is not used, eld sup-
port must be provided up to the center of gravity. This
support can be metal, wood or concrete.
3. Level wall sleeve side to side and pitch to outside 1/8"/ft.
to assure proper sleeve drainage to outside. Anchor with
appropriate fasteners. Use holes provided (see Figure 15,
page 12) or drill additional holes as required to secure
rmly.
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.
4. Caulk the wall sleeve to the wall opening on both the
inside and outside perimeter. This can be done from the
inside of the building. Be careful not to plug the weep
holes.
Note: When using recessed louver wall sleeve, level and plumb wall
sleeve using the top and sides of the sleeve and the chassis slide rails.
DO NOT level using the bottom of the wall sleeve as it has a built in
pitch to drain.
