• 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 FILTERS:
Before attempting to start
your furnace, be sure the furnace air filters are 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
the water supply valve.
3. Make sure blower access door is secured in place.
4. Set your room thermostat to the lowest temperature
setting. (See Fig. 5.)

5. Turn on electric power to the furnace. (See Fig. 6.)
6. Open the oil supply valve. (See Fig. 7.)

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
transformer energizes the fan control board. The fan
control energizes the ignition control. The ignition
control will automatically light the burner.
The electronic fan control automatically turns on
the blower after 60 sec. Fan on control is not adjust-
able. 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 a continuous ignition
control. If the main burner does not ignite within
30 sec from the call for heat, the control will lock
out. The red button on top of the control must be
depressed for 3 sec 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: Set-
ting the thermostat back a few degrees and compen-
sating for the difference 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 the tempera-
ture 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 2 selec-
tions, AUTO and ON. When thermostat is set to
AUTO, the furnace blower cycles on and off, con-
trolled by the thermostat. In ON mode, the furnace
blower runs continuously. This keeps the tempera-
