NOTICE:
The chase should be constructed in a manner
of all outside walls of the home to prevent cold air drafting
problems. The chase should not break the outside build-
ing envelope in any manner. Walls, ceiling, baseplate, and
cantilever floor of the chase should be insulated. Vapor
and air infiltration barriers should be installed in the chase
as per regional codes for the rest of the home. Addition-
ally, in regions where cold air infiltration maybe an is
-
sue, the inside surfaces may be drywalled and taped (or
equivalent method may be used) to achieve maximum air
tightness.
The appliance can be recessed into the wall. When in-
stalled in a recessed opening on an exterior wall in cooler
climates, a chase may be required by local building codes
to accommodate insulation.
NOTICE:
Insulation and other loose materials must be
secured to maintain the air clearance between the appli-
ance and interior envelope of the wall opening. This will
ensure that the appliance can circulate air to its room
temperature sensor for maximum performance of the
Thermostat function.
