WARNING
AnnuAl inSpeCtion
The furnace should be inspected by a qualied 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 or-
der 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 ame, and
ame signal.
• Wiring. Check electrical connections for tightness
and/or corrosion. Check wires for damage.
• Filters.

CAUTION
filter mAintenAnCe
Improper lter maintenance is the most common cause of
inadequate heating or cooling performance. Filters should
be cleaned (permanent) or replaced (disposable) as required.
filter removAl
Depending on the installation, differing lter arrangements can
be applied. Filters can be installed in either the central return
register or a side panel external lter rack (upow only). A
media air lter or electronic air cleaner can be used as an al-
ternate lter. Follow the lter sizes given in the Recommended
Minimum Filter size table to ensure proper unit performance.
To remove lters from an external lter rack in an upright up-
ow installation, follow the directions provided with external
lter rack kit.
horizontal unit filter remoVal
Filters in horizontal installations are located in the central
return register or the ductwork near the furnace.
To remove:
1. Turn OFF electrical power to furnace.
2. Remove lter(s) from the central return register or
ductwork.
3. Replace lter(s) by reversing the procedure for removal.
4. Turn ON electrical power to furnace.
media air filter or eleCtroniC air Cleaner remoVal
Follow the manufacturer’s directions for service.
burnerS
Visually inspect the burner ames periodically during the heat-
ing season. Turn on the furnace at the thermostat and allow
several minutes for ames to stabilize, since any dislodged
dust will alter the ames 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, oating, or lifting off.
Flames must not impinge on the sides of the heat exchanger
ring 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.
flAme SenSor (quAlified ServiCer only)
Under some conditions, the fuel or air supply can create a
nearly invisible coating on the ame sensor. This coating acts
as an insulator causing a drop in the ame sense signal. If the
ame sense signal drops too low the furnace will not sense
ame and will lock out. The ame sensor should be carefully
cleaned by a qualied servicer using steel wool. Following
cleaning, the ame sense signal should be as indicated in the
Specications Sheet.
flue pASSAgeS (quAlified ServiCer only)
The heat exchanger ue passageways should be inspected
at the beginning of each heating season.
before leaVing an inStallation
• Cycle the furnace with the thermostat at least three
times. Verify cooling and fan only operation.
• Review the Owner’s Manual with the homeowner and
discuss proper furnace operation and maintenance.
• Leave literature packet near furnace.
