END USER INSTRUCTIONS - THERMOSTAT CONTROL & BURNER LOCKOUT
(ALL MODELS)
The boiler is factory fitted with a burner control box lockout safety feature which operates automatically if a fault occurs
in the burners operation. Should this occur, the red light on the front of the burner - see burner section page 40 or boiler
photo - will illuminate and its cause must be investigated. This could be caused by:
A. An interruption in the fuel supply (eg. empty oil supply tank).
B. An electrical supply fault.
C. A fault with the burner or its safety control system.
D. The failure of a component (eg. photo cell).
E. Worn or dirty oil nozzle.
Before attempting to restart the boiler the front panel and the burner cover should be removed and a visual check
made for any obvious problems such as oil leaks, loose connections etc.

TO RESTART THE BOILER:
1. Press reset button see burner section or boiler photo.
2. Ensure that the boiler thermostat, time switch (if fitted) and any external controls connected to the boiler are set
to call for heat.
3. Check that the oil supply valves and remote sensor fire valve are open and that there is sufficient oil in the tank.
4. Check that the burner lockout light is unlit and with the mains on, the boiler will be ready to commence its
start sequence.
