Control Box - Oil Fired Heaters
High /Low oil burners although following the general sequence as described below also have extra functional stages
related to air damper positions. Refer to burner manufacturers instructions for further detail.
(See also the Burner Manufacturer's Instructions)
2.2.1
The oil fired burner fitted to the heater is controlled by a fully automatic control box and photoelectric flame monitor unit.
This control ensures the safe start, ignition and stop sequence and also monitors the safe presence of a flame.
If the flame should fail, or fail to be monitored, then the control will go to the safety shut down lockout condition. The
button on the front of the control box will light to indicate this. This button will then need to be pressed in manually to
reset the control box to recommence the burner firing cycle.
This is a thermal control which, following a lockout condition, cannot be reset until the thermal element has cooled. This
takes approximately one minute.
2.2.2
Operating Sequence
The operating sequence of the oil fired control boxes are as shown in Figure 2.1.
WARNING:
The control should not be reset from lockout more than three times without identifying and correcting the
cause. Residual fuel oil in a combustion chamber is an explosion risk.
