Annual Fuel Utilization Efficiency (AFUE) numbers are determined in accordance with DOE Test procedures.

Wire size and over current protection must comply with the National Electrical Code (NFPA-70-latest edition) and all local codes. The furnace shall be installed so that the electrical components are protected from water.

FIGURE 17: Electrical Wiring

1.Provide a power supply separate from all other circuits. Install over- current protection and disconnect switch per local/national electrical codes. The switch should be close to the unit for convenience in servicing. With the disconnect or fused switch in the OFF position, check all wiring against the unit wiring label. Refer to the wiring dia- gram in this instruction.

2.Remove the wiring box cover screws. Route all power wiring through a conduit connector or other proper bushing that has been installed into the unit opening and the junction box. In the junction box there is a black wire, a white wire and a green ground screw. Connect the power supply as shown on the unit’s wiring label on the inside of the blower compartment door or the wiring schematic in this section. Connect the black wire to L1 (hot) from the power supply. Connect the white wired to neutral. Connect the ground wire (installer-supplied) to the green (equipment ground) screw. An alternate wiring method is to use a field-provided 2” (5.1 cm) x 4” (10.2 cm) box and cover on the outside of the furnace. Route the furnace leads into the box using a protective bushing where the wires pass through the furnace panel. After making the wiring con- nections replace the wiring box cover and screws. Refer to Figure 17.

3.The furnace's control system requires correct polarity of the power supply and a proper ground connection. Refer to Figure 17.

The power connection leads and wiring box may be relocated to the left side of the furnace. Remove the screws and cut wire tie holding excess wiring. Reposition on the left side of the furnace and fasten using holes provided.

LOW VOLTAGE CONTROL WIRING CONNECTIONS

Install the field-supplied thermostat by following the instructions that come with the thermostat. With the thermostat set in the OFF position and the main electrical source disconnected, connect the thermostat wiring from the wiring connections on the thermostat to the terminal board on the ignition module, as shown in Figure 17. Electronic thermo- stats may require the common wire to be connected. Apply strain relief to thermostat wires passing through cabinet. If air conditioning equip- ment is installed, use thermostat wiring to connect the Y and C termi- nals on the furnace control board to the proper wires on the condensing unit (unit outside).

Set the heat anticipator in the room thermostat to 0.4 amps. Setting it lower will cause short cycles. Setting it higher will cause the room temperature to exceed the set points.

Some electronic thermostats do not have adjustable heat anticipa- tors. They should be set to six cycles per hour. Follow the thermostat manufacturer's instructions.

The 24-volt, 40 VA transformer is sized for the furnace components only, and should not be connected to power auxiliary devices such as humidifiers, air cleaners, etc. The transformer may provide power for an air conditioning unit contactor.
