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 degrees 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 supply

outlet 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 furnace
casing to attach supply side air duct, humidifier, or other

accessories. All accessories MUST be connected to duct external

to furnace casing.
