WARNING
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.

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.

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.

return register or the ductwork near the furnace.
To remove:
1. Turn OFF electrical power to furnace.
2. Remove filter(s) from the central return register or
ductwork.

WARNING
Burner Flame
Figure 47
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 dis -
lodged dust will alter the flames normal appearance. Flames
should be stable, quiet, soft, and blue (dust may cause or -
ange 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.
