ISCELLANEOUS

FAULT R ECALL

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 F ROM L OCKOUT

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

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.

WARNING

ANNUAL I NSPECTION

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.

CAUTION

FILTER M AINTENANCE

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

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.
