CAUTION
! !
The wall sleeve is not intended as the sole support for
the unit. Therefore, additional support must be provided
by a rigid structure that bears the weight of the unit and
provides an interface for “return air” ducting.
In certain jurisdiction, combustible material is not
allowed to be exposed to return air. For those
municipalities, a support structure can be constructed
using either OPTION 2 or OPTION 3 concepts as per
the material availability.
a. Carefully measure the unit and choose a strong
building material for the support structure.
b. The unit should be additionally supported for
leveling purposes.
• First, the supporting platform must be built, see
(FIG. 15). It can be constructed of plywood and
framing lumber. FIG. 16 is showing alignment of the
platform top with the base panel of the wall sleeve.
Before building support structure,
consider the following:
