3. The spark igniter and gas valve energizes for 7
seconds. NOTE: The igniter produces a very intense
electrical spark that ignites the gas.
4. Main burners light and control detects presence of
ÀDPH
5. The 30-second HEAT FAN ON delay time begins after
the main burners light.
6. The unit delivers heat to the conditioned space until

7. The gas valve de-energizes. The induced draft blower
continues operation for a 29-second post-purge.
Two-Stage Models:
If the call is for low stage heat, the induced draft blower
switches to low speed and the high stage gas valve closes
5 seconds after the main burners light. If call is for high
stage heat, induced draft blower remains at high speed and
high stage gas valve remains open.
There is an adjustable HEAT FAN OFF delay of approxi-

moved, the blower will operate for 30 seconds at high heat
speed then switch to low heat speed for the remainder of
the selected HEAT FAN OFF delay.

1. Thermostat calls for cooling. The compressor and
outdoor fan are energized.
Two-Stage Models:
If the thermostat call is for low stage cooling, the com-
pressor and outdoor fan are energized at low stage. If the
thermostat call is for high stage cooling, the compressor
and outdoor fan are energized at high stage.
2. Approximately seven seconds later, the indoor fan
starts.
3. The unit will deliver cooling to the conditioned space

1. Thermostat calls for FAN ONLY by energizing “G”.
2. Approximately seven seconds later, the indoor fan
starts.
Two-Stage Models:
Indoor fan is energized at low heat speed.
3. The indoor fan continues to run for approximately 60
seconds after “G” is de-energized.
Two-Stage Models:
The indoor fan is immediately de-energized once the ther-
mostat “G” is de-energized.

This unit is equipped with an electronic ignition device to
automatically light the main burners. It also has a power
vent blower to exhaust combustion products.
On new installations, or if a major component has been
replaced, the operation of the unit must be checked.
Check unit operation as outlined in the following instruc-
tions. If any sparking, odors, or unusual sounds are en-

errors, or obstructions in or near the blower motors. Duct
covers must be removed before operating unit.
Rollout Protection Control
The rollout protection device opens, cutting power to the
JDVYDOYHLIWKHÀDPHVIURPWKHEXUQHUVDUHQRWSURSHU-
ly drawn into the heat exchanger. The rollout protection
device is located on the burner bracket. The reason for
elevated temperatures at the control should be determined
and repaired prior to resetting this manual reset control.
