Lennox ELITE Series Installation Instructions Manual page 38

One 24V "H" 1/4" spade terminal is provided on the furnace
integrated control. See figure 58 for integrated control con-
figuration. The terminal is energized in the heating mode
when the combustion air inducer is operating and the pres-
sure switch is closed. Any humidifier rated up to 0.5 amp
can be connected to this terminal with the ground leg of the
circuit connected to ground or the "C" terminal.

Install the room thermostat according to the instruc-
tions provided with the thermostat. See figure 55 for
thermostat designations. If the furnace is being
matched with a heat pump, refer to the FM21 installa-
tion instruction or appropriate dual fuel thermostat in-
structions.
Indoor Blower Speeds
1 − When the thermostat is set to FAN ON," the indoor
blower will run continuously on the fan speed when
there is no cooling or heating demand.
2 − When the EL195UH is running in the heating mode, the
indoor blower will run on the heating speed.
3 − When there is a cooling demand, the indoor blower will
run on the cooling speed.
Generator Use − Voltage Requirements
The following requirements must be kept in mind when
specifying a generator for use with this equipment:
D The furnace requires 120 volts + 10% (Range: 108
volts to 132 volts).
D The furnace operates at 60 Hz + 5% (Range: 57 Hz to
63 Hz).
D The furnace integrated control requires both polarity
and proper ground. Both polarity and proper grounding
should be checked before attempting to operate the
furnace on either permanent or temporary power.
D Generator should have a wave form distortion of less
than 5% THD (total harmonic distortion).
