Upflow and Horizontal Furnaces
Connect supply-air duct to flanges on furnace supply-air outlet.
Bend flange upward to 90 ° with wide duct pliers. (See Fig. 14.)
The supply-air duct must be connected to ONLY the furnace
supply-outlet-air duct flanges or air conditioning coil casing
(when used). DO NOT cut main furnace casing side to attach
supply air duct, humidifier, or other accessories. All accessories
MUST be connected to duct external to furnace main casing.
NOTE: For horizontal applications, the top-most flange may be
bent past 90 ° to allow the evaporator coil to hang on the flange
temporarily while the remaining attachment and sealing of the
coil are performed.
Downflow Furnaces
Connect supply-air duct to supply-air outlet on furnace. Bend
flange inward past 90 ° with wide duct pliers. (See Fig. 14.) The
supply-air duct must be connected to ONLY the furnace
supplyoutlet or air conditioning coil casing (when used). When
installed on combustible material, supply-air duct must be
connected to ONLY the factory-approved accessory subbase or a
factory-approved air conditioning coil casing. DO NOT cut main
