Generator Use - Voltage Requirements
•
The furnace requires 120 volts ± 10% (Range: 108 volts
to 132 volts)
• The furnace operates at 60 Hz ± 5% (Range: 57 Hz to
63 Hz)
• The furnace integrated control requires both proper
polarity and proper ground. Both polarity and proper
grounding should be checked before attempting to
operate the furnace on either permanent or temporary
power.
• Generator should have a wave form distortion of less
than 5% THD (total harmonic distortion).
terminals. If a humidifier rated at greater than one amp is
connected to this terminal, it is necessary to use an external
relay. See Figure 56 for control board configuration. This
terminal is energized in the heating mode when the
combustion air inducer is operating.
Install the room thermostat according to the instructions
provided with the thermostat. See Figure 53 for thermostat
designations. If the furnace is being matched with a heat
pump, refer to the FM21 installation instruction or appropriate
