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.

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 duct-
work above a counterflow furnace. A media air filter or elec-
tronic 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 infor-
mation for removal and installation of filters.
FILTER REMOVAL PROCEDURE
Media Air Filter or Electronic Air Cleaner Removal
Follow the manufacturer's directions for service.
Horizontal Unit Filter Removal
Filters in horizontal installations are located in the central
return register.
INDUCED DRAFT AND CIRCULATION BLOWERS
The bearings in the induced draft blower and circulator blower
motors are permanently lubricated by the manufacturer. No
further lubrication is required. Check motor windings for ac-
cumulation of dust which may cause overheating. Clean as
necessary.
