Annual Inspection

The furnace should be inspected by a qualified installer, or
service 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 necessary.
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.

Filter 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. When replacing a filter, it must be replaced
with a filter of the same type and size.

Burners

Visually inspect the burner flames periodically during the heating
season. Turn on the furnace at the thermostat and allow several
minutes for flames to stabilize, since any dislodged dust will
alter the flames normal appearance. Flames should be stable,
quiet, soft, and blue (dust may cause orange tips but they must
not be yellow). They should extend directly outward from the
burners without curling, floating, or lifting off. Flames must
not impinge on the sides of the heat exchanger firing tubes.

Induced Draft and Circulator Blowers

The bearings in the induced draft blower and circulator blow-
er motors are permanently lubricated by the manufacturer.
No further lubrication is required. Check motor windings for
accumulation of dust which may cause overheating. Clean as
necessary.
