department before attempting to re-set the error.

BoileR tHeRMostat/tHeRMistoR FunCtion
The control thermostat on the boiler allows the householder
to vary temperature to central heating from a low of 60˚C
to 80˚C, depending on the model. Thermostats have a
tolerance of + 4˚C.
In accordance with EU boiler standards, your boiler is also
fitted with a safety high limit thermostat, fixed at 110˚C.
This system protects the boiler in the event of the control
thermostat failing and keeps the boiler safe.
The safety high limit thermostat will shut the boiler off
and will require the limit button to be pushed to restart
the boiler. It is recommended to call a service engineer to
establish the cause.
BuRneR loCKout
The boiler is factory fitted with a burner control box
lockout safety feature which operates automatically if a fault
occurs in the burner operation. Should this occur, the light
on the front of the burner will illuminate.
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 burner component.
e. Worn or dirty oil nozzle.
F. Incorrect flue installation.
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. This should be done by a service engineer.
