!

WARNING

24--V Wiring

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

36. Connect terminal Y as shown in Fig. 32 for proper cooling

operation. Use only AWG No. 18, color--coded, copper thermostat
wire.

NOTE

: Use AWG No. 18 color-coded copper thermostat wire for

lengths up to 100 ft. (31 M). For wire lengths over 100 ft., use
AWG No. 16 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. See Fig. 36.

Accessories

(See Fig. 37 and 36.)

1. Electronic Air Cleaner (EAC)

Connect an accessory Electronic Air Cleaner (if used) using
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.

2. Humidifier (HUM)

The HUM terminal is a 24 VAC output, energized when the gas

valve relay is operating during a call for heat.

Connect an accessory 24 VAC, 0.5 amp. maximum humidifier (if
used) to the

¼

--in. male quick--connect HUM terminal and

COM--24V screw terminal on the control board thermostat strip.

NOTE

: If the humidifier has its own 24 VAC power supply, an

isolation relay may be required. Connect the 24 VAC coil of the
isolation relay to the HUM and COM/24V screw terminal on the
control board thermostat strip. See Fig. 37.

Alternate Power Supplies

This furnace is designed to operate on utility generated power
which has a smooth sinusoidal waveform. If the furnace is to be

operated on a generator or other alternate power supply, the

alternate power supply must produce a smooth sinusoidal
waveform for compatibility with the furnace electronics. The

alternate power supply must generate the same voltage, phase, and
frequency (Hz) as shown in Table 11 or the furnace rating plate.
Contact the alternate power supply manufacturer for specifications
and details.
Power from an alternate power supply that is non-sinusoidal may

damage the furnace electronics or cause erratic operation.
