FURNACE OPERATION INFORMATION

During the heating season, the opera-
tion of the furnace is fully automatic.

TO START THE FURNACE:

1. First read these instructions and
safety notices thoroughly.
2. Set the thermostat to the lowest
setting.
3. Ensure that all supply air registers
and return air grilles are open.
4. Turn off the electric power to the
furnace.
5. Remove the burner access door.
6. Ensure that the appliance manual
shut-off valve is in the "ON" posi-
tion. The valve handle is normally
in-line with the gas pipe and valve
body when it is in the "ON" posi-
tion; perpendicular to the gas pip-
ing and valve body when it is in
the "OFF" position.
7. Honeywell gas valve: no action
required. White-Rodgers
valve: turn the manual gas control
knob to the "OFF" position (see
Fig. 5).
8. Wait 5 minutes to clear out any
gas. If, after this time you smell
gas, STOP. Turn the appliance
manual shut-off valve to the "OFF"
position. If burning propane or
other LP gas, smell for gas near
the floor since propane and butane
are both heavier than air. If after
this time you do not smell gas,
continue to the next step.
9. Honeywell gas valve: Ensure that
the "Ignition System
Switch" is in the "ON" position (see
Fig. 4). White-Rodgers gas valve:
turn the manual gas control knob
to the "ON" position.
NEVER USE TOOLS TO TURN THE
MANUAL GAS CONTROL KNOB. IF
THE CONTROL KNOB WILL NOT
TURN BY HAND, DO NOT ATTEMPT
TO FORCE IT. DOING SO COULD
RESULT IN FIRE OR EXPLOSION
RESULTING
PERSONAL INJURY OR DEATH, OR
PROPERTY
QUALIFIED
CONTRACTOR, SERVICE AGENCY
OR GAS SUPPLIER.
10. Replace the burner access door,
ensuring that it is properly in place.
11. Restore the electric power to the
furnace.
12. Adjust the thermostat to the de-
sired setting. If the thermostat also
controls an air conditioning sys-
tem, ensure that the thermostat
system switch is in the "HEAT" or
gas
"AUTO" mode.

If this is the first time that the furnace
has undergone a trial ignition since
installation, or if there has been work
done on the gas lines, the furnace
might not light because of air trapped
in the gas supply line.

cedure and call your installer, service
