Power Cord Installation in Furnace J-Box

NOTE: Power cords must be able to handle the electrical requirements listed in Table 6. Refer to power cord manufacturer’s listings.

1.Remove cover from J-Box.

2.Route listed power cord through 7/8-in. (22 mm) diameter hole in J-Box.

3.Secure power cord to J-Box bracket with a strain relief bushing or a connector approved for the type of cord used.

4.Secure field ground wire to green ground screw on J-Box bracket.

5.Connect line voltage leads as shown in Fig. 25.

6.Reinstall cover to J-Box. Do not pinch wires between cover and bracket.

BX Cable Installation in Furnace J-Box

1. Remove cover from J-Box.

2.Route BX cable into 7/8-in. (22 mm) diameter hole in J-Box.

3.Secure BX cable to J-Box bracket with connectors ap- proved for the type of cable used.

4.Secure field ground wire to green ground screw on J-Box bracket.

5.Connect line voltage leads as shown in Fig. 25.

6.Reinstall cover to J-Box. Do not pinch wires between cover and bracket.

24-V Wiring

Make field 24-v connections at the 24-v terminal strip. (See Fig.

25- 34.) Connect terminal Y/Y2 as shown in Fig. 27-34 for proper cooling operation. Use only AWG No. 18, color-coded, copper thermostat wire.

The 24-v circuit contains an automotive-type, 3-amp. fuse located on the control. Any direct shorts during installation, service, or maintenance could cause this fuse to blow. If fuse replacement is required, use ONLY a 3-amp. fuse of identical size.

ACCESSORIES

1.Electronic Air Cleaner (EAC)

Connect an accessory Electronic Air Cleaner (if used) us- ing 1/4-in female quick connect terminals to the two male 1/4-in quick-connect terminals on the control board 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. 26.)

2.Humidifier (HUM)

Connect an accessory 24 VAC, 0.5 amp. maximum hu- midifier (if used) to the 1/4-in male quick-connect HUM terminal and COM-24V screw terminal on the control board thermostat strip. The HUM terminal is energized when blower is energized in heating. (See Fig. 26.)

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

VENTING

The furnace shall be connected to a listed factory built chimney or vent, or a clay-tile lined masonry or concrete chimney. Venting into an unlined masonry chimney or concrete chimney is prohibited.

When an existing Category I furnace is removed or replaced, the original venting system, may no longer be sized to properly vent the 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, and spillage of combustion products into the living space.
