ƽ WARNING
Prevent combustion air contamination
Do not install unit in locations that can allow contamination
of combustion air. Refer to Table 1A for products and areas
which may cause contaminated combustion air.
Under no circumstances is the manufacturer to be held
responsible for water damage in connection with this appliance,
or any of its components. If flooding is possible, elevate the
boiler sufficiently to prevent water from reaching the boiler.
Outdoor vent / air intake location
The flue products discharged from the
flue outlet on the outdoor vent may be
very hot. Avoid touching or other direct
contact with the flue gases or the vent
termination assembly. These components
are hot and direct contact can result in
burns.
ƽ WARNING
To prevent recirculation of the flue products into the
combustion air inlet, follow all instructions in this section.
Flue gas condensate can condense on exterior walls or on the
vent. Some discoloration to exterior building or unit surfaces
can be expected. Adjacent brick or masonry surfaces should
be protected with a rust resistant sheet metal plate.
Maintain a minimum of 24" (610mm) clearance to the side
of the air inlet.
Locate the outdoor vent termination at least 48" (1.22m)
below and 48" (1.22m) horizontally from any window, door,
walkway or gravity air intake.
Locate outdoor unit at least 10 feet (3.05m) away from any
forced air inlet.
Multiple outdoor unit installations require 24" (.61m)
clearance between each vent termination.
Clearances around outdoor installations can change with
time. Do not allow the growth of trees, shrubs or other plants
to obstruct the proper operation of the outdoor vent system.
