ELECTRICAL OPERATION HAZARD
Failure to follow this warning could result in personal injury
or death.
HIGH VOLTAGE AT IGNITER. Severe electrical shock,
could result.
• If a suspected malfunction occurs with your oil control system,
such as the burner not lighting when it should, refer to the
"Shutting Down Your Furnace" section and call your dealer as
soon as possible.
• Check Air Filter: Before attempting to start your furnace, be
sure the furnace air filter is clean and in place. See "Performing
Routine Maintenance" section in this manual. Then proceed as
follows:
Steps for Starting Your Furnace
1. Open all warm air registers and make sure that all return-air
grills are unobstructed.
2. If a humidifier is installed with your system, open water
supply valve.
3. Make sure blower access door is secured in place.
4. Set your room thermostat to lowest temperature setting.
5. Turn on electric power to furnace.

6. Open oil supply valve.
7. Check all connections to ensure there are no leaks.
8. Set room thermostat to a temperature slightly above room
temperature. This will automatically signal the furnace to
start.

9. When the thermostat calls for heat, power from the trans-
former energizes the fan control board. The fan control en-
ergizes the ignition control. The ignition control will auto-
matically light the burner.
The electronic fan control automatically turns on the
blower. The air moved over the heat exchanger by the
blower is warmed and passes through the ducts to the room
registers.
This unit is equipped with continuous ignition control. If
the main burner does not ignite within 30 seconds from the
call for heat, the control will lock out. The red button on
top of the control must be depressed for three (3) seconds in
order to reset the control. The control CANNOT be reset
from the room thermostat.
10. Set your thermostat to the temperature that satisfies your
comfort requirements. SUGGESTION: Setting the ther-
mostat back a few degrees and compensating for the differ-
ence with warmer clothing can make a big difference in
your fuel consumption on extremely cold days. The few
degrees at the top of your thermostat "comfort level" are the
most costly degrees to obtain.
When room temperature drops below temperature selected on the
thermostat, the furnace will be switched on automatically. When
room temperature reaches the degree selected on the thermostat, the
furnace will be switched off automatically.
Some thermostats have a FAN mode with two (2) selections,
AUTO and ON. When thermostat is set to AUTO. the furnace
blower cycles on and off, controlled by the thermostat. In ON
mode. the furnace blower runs continuously. This keeps the
temperature level in your home more evenly balanced. It also
continuously filters indoor air.
NOTE: Constant low-speed blower operation can also be
achieved by turning on the constant blower rocker switch located
on the front right side of the furnace. Regardless of room
thermostat setting, blower will run continuously in low speed to
provide constant air circulation. This keeps the temperature level
in your home more evenly balanced. It also continuously filters
indoor air. If constant blower rocker switch is turned off, room
thermostat will control blower operation.
SHUTTING DOWN YOUR FURNACE
Should you need to shut down your furnace for service or
maintenance, you will need to turn the furnace off. The following
procedures must be followed.
1. Set thermostat to lowest setting.
2. Turn off all electrical power to the furnace.
3. Close oil supply valve.
