Installing Wall Sleeve
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
flange (see
Figure 8, 9 & 10
).
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 flush with
the exterior of the building. The center of gravity is
approximately 10-3/4" (273mm) from the rear face of
the standard wall sleeve. If a subbase is not used, field
support 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 1/4"/ft.
to assure proper sleeve drainage to outside. Anchor with
appropriate fasteners. Use holes provided (see
Figure
14 on page 12
) or drill additional holes as required to
secure firmly.
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.
