A fault in the electrical supply i.e. very low voltage.2. An interruption in the fuel supply.3. Faulty operation of the Burner or its safety control system.4. A component failure.5. A fault in heating system control external to Boiler.Before attempting to restart the Boiler, remove the front panel of the Boiler and look forany obvious problems i.e. oil leaks.Restart Procedure:-1. Check that there is sufficient oil in the tank and that the supply valves are open.2. Check that the Boiler thermostat, time switch or programmer and any other systemcontrols are set to call for heat.3. Press and release the red glowing plunger Reset button on the Burner control box.The red light will extinguish and the Burner will commence the start sequence.After 15 seconds, the Burner should fire normally.If the Burner does not fire, the lockout symptoms will persist and the Burner control boxReset button will again glow.4.

Servicing at the stated intervals is a prerequisite of the Boiler Warranty.A competent engineer should be sought to carry out the servicing at the requiredintervals. An OFTEC trained and registered engineer would be a good choice.SERVICE INTERVALFUEL - 28 Second Viscosity Class C Kerosene - Service required once a year.FUEL - 35 Second Viscosity Class D Heating Oil - Service required twice a year.33333
