WARNING
To avoid electrical shock, injury or death, disconnect electrical power before performing any maintenance.
If you must handle the igniter, handle with care. Touching the igniter element with bare fingers, rough handling, or
vibration could damage the igniter resulting in premature failure. Only a qualified servicer should ever handle the
igniter.
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 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.
•
Wiring. Check electrical connections for tightness and/or corrosion. Check wires for damage.
•
Filters.

WARNING
To prevent death, personal injury or property damage due to fire, never operate furnace without a filter installed.
Dust and lint will build up on internal parts resulting in loss of efficiency, equipment damage and possible fire.
CAUTION
To ensure proper unit performance, adhere to the filter sizes given in the Specifications Sheet.
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.
