INSTALLATION
NOTICE
Cabinet air leakage is less than 2% at 1.0 in. W.C. Cabinet air
leakage is less than 1.4% at 0.5 in. W.C. when tested in accor-
dance with ASHRAE Standard 193.
Upflow Installation
NOTE: The furnace must be pitched as shown in Fig. 26 for
proper condensate drainage.
Supply Air Connections
For a furnace not equipped with a cooling coil, the outlet duct shall
be provided with a removable access panel. This opening shall be
accessible when the furnace is installed and shall be of such a size
that the heat exchanger can be viewed for possible openings using
light assistance or a probe can be inserted for sampling the air
stream. The cover attachment shall prevent leaks.
Connect supply−air duct to flanges on furnace supply−air outlet.
Bend flange upward to 90_ with wide duct pliers. See Fig. 22. 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 supply−side
accessories MUST be connected to duct external to furnace main
casing.
