ESETTING ROM OCKOUT
Furnace lockout results when a furnace is unable to achieve
ignition after three attempts. It is characterized by a non-func-
tioning furnace and a one flash diagnostic LED code from the
red LED. If the furnace is in "lockout", it will (or can be) reset in
any of the following ways.
1. Automatic reset. The integrated control module will
automatically reset itself and attempt to resume normal
operations following a one hour lockout period.
2. Manual power interruption. Interrupt 115 volt power to
the furnace for 1 - 20 seconds.
3. Manual thermostat cycle. Lower the thermostat so that
there is no longer a call for heat for 1 - 20 seconds then
reset to previous setting.
NOTE: If the condition which originally caused the lockout still
exists, the control will return to lockout. Refer to the Diagnostic
Chart for aid in determining the cause.

NNUAL INSPECTION
The furnace should be inspected by a qualified installer, or ser-
vice 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 neces-
sary.
• 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.

A return air filter is not supplied with this furnace; however,
there must be a means of filtering all of the return air. The in-
staller will supply filter(s) at the time of installation.

ILTER AINTENANCE
Improper filter maintenance is the most common cause of in-
adequate 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.

Become familiar with filter location and procedures for removal,

ILTER EMOVAL
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 alter-
nate filter. Follow the filter sizes given in the Recommended
Minimum Filter size table or instruction provided by the media
or electronic air cleaner manufacturer 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. For further details, see your distributor.

NDUCED RAFT AND
The bearings in the induced draft blower and circulator blower
motors are permanently lubricated by the manufacturer. No fur-
ther lubrication is required. Check motor windings for accumu-
lation of dust which may cause overheating. Clean as neces-
sary.
