FAULT RECALL

The ignition control is equipped with a momentary push-button switch that can be used to display the last six faults on the dual 7-segment LED’s. The control must be in Standby Mode (no thermostat inputs) to use the feature. Depress the switch for approximately 2 seconds. Release the switch when the LED’s are turned off. The last six faults will be displayed most recent to least recent on the dual 7-segment LED’s.

NOTE: Consecutively repeated faults are stored a maximum of

three times. Example: A clogged return air filter causes the furnace limit to trip repeatedly. The control will only store this fault the first three consecutive times the fault occurs.

RESETTING FROM LOCKOUT

Furnace lockout results when a furnace is unable to achieve ignition after three attempts during a single call for heat. It is characterized by a non-functioning furnace and a E 0 code dis- played on the dual 7-segment display. If the furnace is in “lock- out”, it will (or can be) reset in any of the following ways.

1.Automatic reset. The integrated control module will automatically reset itself and attempt to resume normal operations following a one hour lockout period.

2.Manual power interruption. Interrupt 115 volt power to the furnace.

3.Manual thermostat cycle. Lower the thermostat so that there is no longer a call for heat for 1 -20 seconds then reset to previous setting.

NOTE: If the condition which originally caused the lockout still exists, the control will return to lockout. Refer to the Diagnostic Chart for aid in determining the cause.

MAINTENANCE

WARNING

TO AVOID ELECTRICAL SHOCK, INJURY OR DEATH, DISCONNECT ELECTRICAL POWER BEFORE PERFORMING ANY MAINTENANCE. IF YOU MUST HANDLE THE IGNITER, HANDLE WITH CARE. TOUCHING THE IGNITER ELEMENT WITH BARE FINGERS, ROUGH HANDLING OR VIBRATION COULD DAMAGE THE IGNITER RESULTING IN PREMATURE FAILURE. ONLY A QUALIFIED SERVICER SHOULD EVER HANDLE THE IGNITER.

ANNUAL INSPECTION

The furnace should be inspected by a qualified installer, or ser- vice agency at least once per year. This check should be per- formed at the beginning of the heating season. This will ensure that all furnace components are in proper working order and that the heating system functions appropriately. Pay particular attention to the following items. Repair or service as neces- sary.

•Flue pipe system. Check for blockage and/or leakage. Check the outside termination and the connections at and internal to the furnace.

•Heat exchanger. Check for corrosion and/or buildup within the heat exchanger passageways.

•Burners. Check for proper ignition, burner flame, and flame sense.

•Drainage system. Check for blockage and/or leakage. Check hose connections at and internal to furnace.

•Wiring. Check electrical connections for tightness and/ or corrosion. Check wires for damage.

•Filters.

FILTERS

CAUTION

TO ENSURE PROPER UNIT PERFORMANCE, ADHERE TO THE FILTER SIZES GIVEN IN THE RECOMMENDED MINIMUM FILTER SIZE TABLE OR SPECIFICATION SHEET APPLICABLE TO YOUR MODEL.

FILTER MAINTENANCE

Improper filter maintenance is the most common cause of in- adequate heating or cooling performance. Filters should be cleaned (permanent) or replaced (disposable) every two months or as required. When replacing a filter, it must be replaced with a filter of the same type and size.

FILTER REMOVAL

Depending on the installation, differing filter arrangements can be applied. Filters can be installed in either the central return register or a side panel external filter rack (upflow only). A media air filter or electronic air cleaner can be used as an alter- nate filter. Follow the filter sizes given in the Recommended Minimum Filter size table to ensure proper unit performance.

To remove filters from an external filter rack in an upright upflow installation, follow the directions provided with external filter rack kit.

HORIZONTAL UNIT FILTER REMOVAL

Filters in horizontal installations are located in the central re- turn register or the ductwork near the furnace.

To remove:

1.Turn OFF electrical power to furnace.

2.Remove filter(s) from the central return register or ductwork.

3.Replace filter(s) by reversing the procedure for removal.

4.Turn ON electrical power to furnace.

MEDIA AIR FILTER OR ELECTRONIC AIR CLEANER REMOVAL

Follow the manufacturer’s directions for service.
