MAINTENANCE

HIGH VOLTAGE
To avoid personal injury or death due to
electrical shock, disconnect electrical
power before performing any service or
maintenance.
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 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.

• Filters.

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.
FILTERS
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.
WARNING
WARNING
To ensure proper unit performance, adhere to the filter
sizes given in the recommended Minimum Filter Size Table or
Specification Sheet applicable to your model.
Filter Removal
Depending on the installation, differing filter arrangements
can be applied. Filters can be installed in either the central
return register or a side panel external filter rack (upflow
only). A media air filter or electronic air cleaner can be used
as an alternate filter. Follow the filter sizes give n in the
Recommended Minimum Filter size table to ensure proper
unit performance.
To remove filters from an external filter rack in an upright
upflow installation, follow the directions provided with
external filter rack kit.
