NORMAL SEQUENCES OF OPERATION
HEATING
This unit is equipped with an ignition control that automatically lights the main burner. DO NOT attempt to light the main burners by any other method.
1.Thermostat calls for heat. The induced draft blower energizes for a
2.The spark igniter and gas valve energizes for 7 seconds. NOTE: The igniter produces a very intense electrical spark that ignites the gas.
3.The
4.The unit delivers heat to the conditioned space until the thermostat is satisfied.
5.The gas valve deenergizes. The induced draft blower continues operation for a
6.Ignition control begins timing the HEAT FAN OFF delay. There is an adjustable HEAT FAN OFF delay of approximately 120/135/150 seconds (factory set at 150). After the HEAT FAN OFF delay time has elapsed, the blower will deenergize. This allows any additional heat in the heat exchanger to be transferred to the conditioned space.
COOLING
1.Thermostat calls for cooling. The compressor and outdoor fan are energized.
2.Approximately seven seconds later, the indoor fan starts.
3.The unit will deliver cooling to the conditioned space until the thermostat is satisfied.
4.The compressor and outdoor fan will be
5.The indoor fan continues to run for approximately 60 seconds after the thermostat is satisfied. This allows additional cooling from the indoor coil to be transferred to the conditioned space. Then, the indoor fan stops.

STARTUP, ADJUSTMENTS, AND CHECKS
HEATING STARTUP
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 instructions. If any sparking, odors, or unusual sounds are encountered, shut off electrical power and recheck for wiring errors, or obstructions in or near the blower motors. Duct covers must be removed before operating unit.
Heat Anticipator Setting
Set the heat anticipator on the room thermostat to 0.4 amps to obtain the proper number of heating cycles per hour and to prevent the room temperature from overshooting the room thermostat setting.
Rollout Protection Control
The rollout protection device opens, cutting power to the gas valve, if the flames from the burners are not properly 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.
