MAINTENANCE

WARNING
TO AVOID ELECTRICAL SHOCK, INJURY OR DEATH,
DISCONNECT ELECTRICAL POWER BEFORE PER-
FORMING ANY MAINTENANCE.
CAUTION
IF YOU MUST HANDLE THE IGNITOR, HANDLE WITH
CARE. TOUCHING THE IGNITOR BODY WITH BARE FIN-
GERS, ROUGH HANDLING, OR VIBRATION COULD RE-
SULT IN EARLY IGNITOR FAILURE. ONLY A QUALIFIED
SERVICER SHOULD EVER HANDLE THE IGNITOR.
ANNUAL INSPECTION
The furnace should be inspected by a qualified installer, or
service agency at least once per year. This check should be
performed 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 necessary.
• Flue pipe system. Check for blockage and/or leak-
age. Check the outside termination and the connec-
tions at and internal to the furnace.
• Combustion air intake pipe system (where applicable).
Check for blockage and/or leakage. Check the out-
side termination and the connection at 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.
AIR FILTER
WARNING
NEVER OPERATE FURNACE WITHOUT A FILTER IN-
STALLED AS DUST AND LINT WILL BUILD UP ON IN-
TERNAL PARTS RESULTING IN LOSS OF EFFICIENCY,
EQUIPMENT DAMAGE, AND POSSIBLE FIRE.
Filters must be used with this furnace. Filters do not ship
with these furnaces but must be provided by the installer for
proper furnace for proper operation.
Remember that dirty filters are the most common cause of
inadequate heating or cooling performance.
WARNING
DISCONNECT THE ELECTRICAL POWER TO THE FUR-
NACE BEFORE REMOVING THE FILTER OR PERFORM-
ING ANY OTHER MAINTENANCE.
Maintenance
Improper filter maintenance is the most common cause of
inadequate heating or cooling performance. Filters should
be cleaned (permanent) or replaced (disposable) every two
months or as required. It is the owner's responsibility to keep
air filters clean. 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 the central return
register, the bottom of the blower compartment (upflow only),
a side panel external filter rack kit (upflow only), or the
ductwork above a counterflow furnace. A media air filter or
electronic air cleaner can be used as an alternate filter. The
filter sizes given in the Product Design section of this manual
or the product Specification Sheet must be followed to en-
sure proper unit performance. Refer to the following informa-
tion for removal and installation of filters.
Upright Upflow Filter Removal
To remove an internal filter from the bottom of the blower
compartment:
1. Set the thermostat to the OFF position or turn OFF elec-
trical power to furnace.
2. Remove blower compartment door.
3. Push back and up on the wire filter retainer to release it
from under the front lip of the furnace basepan. Do not
remove. To access the filter, tilt the wire filter retainer
upwards.
4. Slide filter forward and out. Vacuum blower compart-
ment.
5. Replace filter and secure retainer opposite of removal.
6. Replace blower compartment door and turn ON thermo-
stat or electrical power to furnace.
To remove filters from an external filter rack in an upright
upflow installation, follow the directions provided with exter-
nal filter rack kit.
To remove internal filter(s) from the retaining rails on the
side(s) of the blower compartment in an upright installation:
1. Set the thermostat to the OFF position or turn OFF elec-
trical power to furnace.
2. Remove the blower compartment door.
3. Grasping the lower portion of the filter, disengage the
filter from the lower railing by lifting it up and toward the
blower. Lower the filter down and pull outward.
