Standard horizontal metal duct covers with insulation come with the
unit and cover the horizontal duct openings. These can be left in place if
the units are converted to downflow.
Integrated Gas Control (IGC) board provides safe and efficient
control of heating and simplifies trouble-shooting through its built-in
diagnostic function.
Cabinets are constructed of heavy duty, phosphated, zinc-coated
prepainted steel capable of withstanding 500 hours in salt spray. Interior
surfaces of the evaporator/heat exchanger compartment are insulated
with cleanable semi-rigid insulation board, which keeps the conditioned
air from being affected by the outdoor ambient temperature and provides
improved indoor air quality. (Conforms to American Society of Heating,
Refrigeration and Air Conditioning Engineers 62.2.) The sloped drain
pan minimizes standing water in the drain. An external drain is provided.
