ELECTRIC WIRING

All electrical wiring must be done in accordance with the

National Electrical Code. The code needs to be legally
authorized in the area where the installation is being
made. The circuit protector device must be located in a
convenient place near the furnace. No lighter than
14 AWG wire should be used in the furnace power
supply circuit. All furnaces covered by this manual and
installed in the United States of America operate on
115 Volts, 60 Cycle, 1-Phase Alternating Current with a
20 amp circuit protector device.

WARNING: Turn off electric power at
circuit protector device before making
any line voltage connections.

WIRING THE FURNACE

The furnace wiring is provided in harness form.

Mount the 4 x 4 junction box to the mounting bracket on
front of the furnace. See Fig. 4 & 5 (page 24)
Connect components as shown in wiring diagram on
page 28.

CAUTION: This furnace is not approved
for use with aluminum wire.

NOTE: 24 volt wires from the transformer/relay to
thermostat need not be enclosed in conduit.
