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.
