1.Remove two screws holding auxiliary J-box. (See Fig. 32.)

2.Rotate J-box 180_ and attach box to left side, using holes provided.

24-v wiring

Make field 24-v thermostat connections at 24-v terminal block on furnace control. Y wire from thermostat MUST be connected to Y/Y2 terminal on control, as shown in Fig. 19, for proper cooling operation. The 24-v terminal block is marked for easy connection of field wiring. (See Fig. 33.) The 24-v circuit contains a 3-amp, automotive-type fuse located on furnace control. (See Fig. 33.)

Any electrical shorts of 24-v wiring during installation, service, or maintenance may cause fuse to blow. If fuse replacement is required, use only a fuse of identical size (3 amp) and type. The furnace control will flash status code 24 when fuse needs replacement.

NOTE: Use AWG No. 18 color-coded copper thermostat wire for lengths up to 100 ft. (30.4M). For wire lengths over 100 ft., (30.4M) use AWG No. 16 wire.

NOTE: For additional thermostat connection diagrams, reference Fig. 52-59.

marked EAC-1 and EAC-2. The terminals are rated for

115VAC, 1.0 amps maximum and are energized during

blower motor operation. (See Fig. 33.)

NOTE: Low stage airflow may slightly increase the trace amount of ozone created by an electronic air cleaner. Individual sensitivity levels to ozone, along with other operating characteristics of electronic air cleaners may affect the amount noticed by an individual. Refer to the air cleaner manufacturer’s installation instructions for more information regarding ozone and ozone reduction methods available for your air cleaner.

!CAUTION

UNIT DAMAGE HAZARD

3.Install power entry hole filler plugs (factory-supplied loose parts bag) in unused power entry holes. (See Fig. 31.)

!WARNING

FIRE OR ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury, death, or property damage.

If manual disconnect switch is to be mounted on furnace, select a location where a drill or fastener will not contact electrical or gas components.

NOTE: If modulating dampers are used, blower motor automatically compensates for modulating dampers. If manual disconnect switch is to be mounted on furnace, select a location where a drill or fastener will not contact electrical or gas components.

Failure to follow this caution may result in unit component damage.

DO NOT connect furnace control HUM terminal to HUM (humidifier) terminal on Thermidistatt, Zone Controller or similar device. See Thermidistatt, Zone Controller, thermostat, or controller manufacturer’s instructions for proper connection.

2.Humidifier (HUM)

Connect an accessory 24 VAC, 0.5 amp maximum humid- ifier (if used) to the 1/4-in. male quick-connect HUM ter- minal and COM-24V screw terminal on the control board thermostat strip. The HUM terminal is energized when blower is energized in heating. (See Fig. 33.)

Removal of Existing Furnaces from Common Vent Systems

When an existing Category I furnace is removed or replaced, the original venting system may no longer be sized to properly vent the remaining attached appliances. An improperly sized Category I venting system could cause the formation of condensate in the furnace and vent, leakage of condensate and combustion products, spillage of combustion products into the living space, etc.
