Electrical Connections
Turn off electric power at the breaker box or service panel before
making any electical connections. The ground connection must be
completed before making line voltage connections. Failure to do so
can result in electrical shock, severe personal injury, or death.
The furnace cabinet must be permanently grounded. A ground screw
is provided in the junction box for this purpose. Failure to properly
ground the furnace cabinet can result in fire, electrical shock,
personal injury, or death.
Electrical Supply
IMPORTANT: All electrical work must conform
to local codes and ordinances or with the
National Electrical Code. If unfamiliar with wiring
and codes, have a licensed electrician perform
the electrical connection.
The electrical supply to the furnace should be
from a 120V, 15 amp protected circuit. Make all
connections inside box (1):
•
Black wire to black wire
•
White wire to white wire
•
Ground wire (green) to ground terminal.
Thermostat
A thermostat is not included with the A-MAIZE-
ING HEAT
®
furnace. Read and follow all
directions included with the thermostat. The
location of the thermostat has an important
effect on the overall performance of the furnace.
The thermostat relay (2) is located above the
electrical supply connection box. Connect the
thermostat wires to terminals “R” and “W” on the
relay.
The relay terminal markings are as follows:
•
“R” - 24V power supply to thermostat
•
“W” - Heat signal from thermostat
•
“G” - Fan full time signal from thermostat
