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. 19. 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.

Return Air Connections

FURNACE RELIABILITY HAZARD

Failure to follow this caution may result in unit component

damage.
Return air connections to either side of the furnace in the

horizontal position can result in nuisance limit switch tripping.

Use only the factory bottom opening of the furnace for the

return air connection.

CAUTION

The return--air duct can only be connected to bottom of the

furnace.

The sides of casing cannot be used for return air

connection. See Fig. 24.

Bottom Return Air Inlet

These furnaces are shipped with bottom closure panel installed in

bottom return--air opening. Remove and discard this panel when

bottom return air is used. To remove bottom closure panel, see Fig.

27 and 28.

Side Return Air Inlet

These furnaces are shipped with bottom closure panel installed in

bottom return--air opening. This panel MUST be in place when

side return air inlet(s) are used without a bottom return air inlet.

Not all horizontal furnaces are approved for side return air

connections See Fig. 24. Where required by code, seal bottom

closure to furnace with tape, mastic, or other durable sealing

method.

1 Lay furnace on the back or side
2 Remove the two (2) screws that secure the bottom

closure panel to the furnace casing and remove the

panel

Filter Arrangement

FIRE, CARBON MONOXIDE AND POISONING

HAZARD

Failure to follow this warning could result in fire, personal

injury or death.
Never operate a furnace without a filter or filtration device

installed. Never operate a furnace with filter or filtration

device access doors removed.

WARNING

The furnace may be used with an optional external media filter

cabinet. The optional media filter cabinet uses either a standard

1-in. (25 mm) filter or 4-in. (102 mm) wide media filter which can

be purchased separately. A field supplied accessory air cleaner may

also be used in place of the media cabinet.

The optional media cabinet is sized for bottom return applications

for use in upflow, downflow and horizontal applications. A 16--in.

(406 mm) media cabinet may be used with the 14--3/16-in. (360

mm) furnace and includes block-off plates

For upflow side return applications, the optional media cabinet (or

field supplied accessory air cleaner) can be installed on the side of

the furnace or side and bottom when a bottom plenum is used. See

Fig. 29 and 22.

For downflow applications, the optional media cabinet (or field

supplied accessory air cleaner) must only be connected to the

bottom opening on the furnace. See Fig. 29 and 23.

For horizontal applications, the optional media cabinet (or field

supplied accessory air cleaner) for all models can be connected to

the bottom opening on the furnace. For side return use in the

horizontal position, refer to Fig. 24. If both side and bottom

openings are used in Fig. 24, each opening used will require an

optional filter.
The optional media cabinet (or field supplied accessory air cleaner)

can also be installed in the common return duct prior to entering

the return air opening in any orientation.
