FURNACE OPERATION
I_WARNING
ELECTRICAL COMPONENTS ARE CONTAINED IN BOTH COMPARTMENTS.
To
AVOID PERSONAL INJURY, ELECTRICAL SHOCK OR DEATH, DO NOT REMOVE
ANY INTERNAL COMPARTMENT COVERS. CONTACT A QUALIFIED SERVICER AT
ONCE IF AN ABNORMAL CONDITION tS NOTICED.
Keep both doors in place except for inspection and maintenance. An
interlock switch prevents furnace operation if the blower door is not
in place.
FURNACE START-UP
1. Close the external manual gas shut-off valve.
2. Turn off the electrical power to the furnace.
3. Set the room thermostat to the lowest possible setting.
4. Remove the burner compartment door.
5. This furnace is equipped with an ignition device which automati-
cally lights the burner. Do not try to light the burner by hand.
6. Move the furnace's gas valve ON/OFF switch to the OFF posi-
tion.
7. Wait five minutes to clear out any gas. Then smell for gas, in-
cluding near the floor as some types of gas are heavier than air.
8. If you smell gas following the five minute waiting period in step 7,
immediately follow the instructions on the cover of this manual.
If you do not smell gas after five minutes, move the furnace's
gas valve ON/OFF switch to the ON position.
9. Replace the burner compartment door.
10. Open the external manual gas shut-off valve.
11. Turn on the electrical power to the furnace.
12. Adjust the thermostat to a setting above room temperature.

FURNACE SHUT DOWN
To shut down your furnace, follow the steps listed below.
1. Set the thermostat to the lowest setting.
2. Integrated control closes gas valve extinguishing flame.
3. Induced draft blower is de-energized following a 15 second de-
lay. The circulator blower is de-energized following a 60, 90,
120, or 180 second delay period.
4. Remove the burner compartment door.
5. Move the furnace's gas valve ON/OFF switch to the OFF posi-
tion.
6. Close the external manual gas shut-off valve.
7. Replace the burner compartment door.
LOCKOUT RESET
Furnace lockout is characterized by a non-functioning furnace
(circulator blower may be running continuously) providing a one
flash 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. One hour automatic reset. Control will automatically reset itself
and attempt to resume normal operations following a one hour
lockout period.
2. Power interruption. Interrupt 115 volt power to the furnace for
between 0 and 20 seconds.
3. 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 be followed. We recommend that at a minimum
system maintenance be performed by a qualified service techni-
cian prior to the beginning of each heating season, and if equipped
with air conditioning prior to that season.
