PROBLEM POSSIBLE CAUSE POSSIBLE ACTION(S)
Burner ignites and Burner shuts off on
reset sometime later during the day or
night.
1. There is air in the fuel supply.
2. The primary control is not
receiving the proper ohm signal
from the cad cell.
3. There is insufficient air pressure.
4. The heater block is cold.
5. The electrodes are fouled.
1. Prime the pump. If the pump will
not prime or there is air in the oil
stream from the pump bleeder,
follow the steps in the next
problem (“Pump will not prime.”)
2. Check for proper ohm signal.
Follow the procedures in the
previous problem (top, page 11-4)
3. Follow the instructions in Section
5 to adjust the air regulator for
proper air pressure. DO NOT turn
the air compressor off while the
boiler is operating. If you turn the
air compressor off at night, turn
the wall thermostat or aquastat
OFF so the burner will not run.
4. DO NOT shut off power to the
boiler overnight, or the heater
block will cool down, and the
burner will not re-start the next
morning. To turn the boiler “off”
overnight, turn the wall thermostat
or aquastat OFF. The heater
block will stay hot.
5. If oil residues have built up on the
electrodes and retention head,
follow the instructions in Section 8
to check for proper draft over fire.
Clean the electrodes and
retention head.
