Lockout Reset
Furnace lockout is characterized by a non functioning furnace
(circulator blower may be running continuously) providing a
diagnostic LED code. Lockout results when a furnace control
detects abnormal conditions. If the furnace is in "lockout," it may
be reset by any of the following methods.
1-hour automatic reset. Control will automatically reset itself
and attempt to resume normal operations following a 1-hour
lockout period.
Power interruption. Interrupt 115-volt power to the furnace
for longer than 20 seconds.
Thermostat cycle. Interrupt thermostat signal to the furnace
for between 0 and 20 seconds.
If the condition which originally caused the lockout still exists, the
control will return to lockout. If your furnace frequently locks out,
a problem exists which must be corrected. Contact a qualified
servicer.
ROUTINE MAINTENANCE
Maintenance is to be performed by a qualified service technician
only. User maintenance is to be restricted to frequent air filter
changes and to ensure the warnings and notices found
elsewhere in this manual are followed. We recommend that at a
minimum, system maintenance be performed by a qualified
service technician prior to the beginning of each heating season,
and, if equipped with air conditioning, prior to air conditioning
season.
WARNING
Personal injury or death may result from improper
maintenance performed by untrained personnel. Call your
installing dealer or other qualified service companies to
perform the maintenance inspection.
WARNING
HIGH VOLTAGE!
Disconnect ALL power before servicing.
Multiple power sources may be present.
Failure to do so may cause property damage,
personal injury or death.
Annual Inspection
The furnace should be inspected and serviced at least once per
year by a qualified service technician. 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. Particular
attention should be paid to the following items. Repair as
necessary.
