OCKOUT
Furnace lockout results when a furnace is unable to achieve igni-
tion after three attempts. It is characterized by a non-functioning
furnace and a one flash diagnostic LED code. 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 0 - 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 0 - 20 seconds.
NOTE: If the condition which originally caused the lockout still
exists, the control will return to lockout. Refer to Section XVIII,
Troubleshooting - Diagnostic Chart for aid in determining the cause.

A
NNUAL 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 fur-
nace components are in proper working order and that the heating
system functions appropriately. Pay particular attention to the fol-
lowing 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.
*NOTE: Please contact your distributor or our website for the applicable product data book referred to in this manual.

AINTENANCE
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 re-
quired. 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 media air filter or
electronic air cleaner can be used as an alternate filter. Follow the
filter sizes given 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. To remove internal filters see Internal Filter Removal section.
Internal filters are an accessory item and are not included with
your furnace. For further details, see your distributor.

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 filter(s) from the central return register or ductwork.
3. Replace filter(s) by reversing the procedure for removal.
4. Turn ON electrical power to furnace.

URNERS
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 dislodged dust will alter
the flames 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 with-
out curling, floating, or lifting off. Flames must not impinge on the
sides of the heat exchanger firing tubes.

The bearings in the induced draft blower and circulator blower
