Steps for Starting Your Furnace

!DANGER

ELECTRICAL SHOCK HAZARD HIGH VOLT- AGE AT IGNITER.

Severe electrical shock, personal injury, or death will 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 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:

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-
