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.

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 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 ensure proper unit performance. Refer to
the following information for removal and installation of fil-
ters.
FILTER REMOVAL PROCEDURE

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.
