diagnostic LED will then display the flash codes associated
with the last five detected faults. The order of display is the
most recent fault to the least recent fault.

ESETTING ROM OCKOUT
Furnace lockout results when a furnace is unable to achieve
ignition after three attempts during a single call for heat. It
is characterized by a non-functioning furnace and a one flash
diagnostic LED code. If the furnace is in "lockout", it 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 then reset to
previous setting. Interrupt thermostat signal to the
furnace for 1 - 20 seconds.
NOTE: If the condition which originally caused the lockout still
exists, the control will return to lockout. Refer to the
Troubleshooting Chart for aid in determining the cause.

NNUAL NSPECTION
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 atten-
tion 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.

Improper filter maintenance is the most common cause of inad-
equate 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.

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 me-
dia air filter or electronic air cleaner can be used as an alternate
filter. Follow the filter sizes given in the Recommended Mini-
mum 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.
