If your furnace does not start
CHECK YOUR THERMOSTAT
Set the thermostat 5 degrees above the room temperature. If it is a clock thermostat, make sure it is timed correctly.
CHECK ELECTRIC SWITCHES
Make sure that all switches affecting the oil burner are “ON”
PRESS OR TURN THE RECYCLING BUTTON
This is on the burner control box which is usually located on the chimney stack, but may be on the burner itself. Caution If the burner runs for a minute or two and shuts off again, DO NOT PRESS THE RECYCLING BUTTON AGAIN.
EXAMINE ELECTRIC FUSE
Check for blown fuses in the meter box and main burner switch box. Replace blown fuses with a new (15 ampere capacity). Screw in tightly
CHECK BOILER WATER LEVEL
If your boiler is equipped with a low water cut-off make sure that the water in the boiler gauge is at the “water line” (usually about half way up the glass) If the level is low, open the water feed valve until correct level is restored. Then close valve tightly.
CHECK PRESSURE GAUGE
(With hot water boiler, check thermometer) If the pressure or temperature is high, the limit control may have stopped the burner. If so burner should re-start when pressure or temperature drops.
CHECK YOUR OIL TANK
Be sure there is oil in the tank and the oil line valve is open.
