INDICATION LIGHTS

There are two indicator lights on the facia panel — POWER ON
and LOCKOUT.
The POWER ON light shows that there is an electrical power
supply to the electrical control panel. This will remain on at all times
provided there is an external electrical supply and the internal fuse
has not blown.
The LOCKOUT light illuminates if a burner ignition failure
occurs. The burner can be reset after two minutes by pressing the
illuminated lockout reset button located on the burner control box.
PLEASE NOTE: Do not attempt to repeatedly restart the boiler
as persistent lockout indicates a fault and you should consult a serv-
ice engineer.

OVERHEAT THERMOSTAT

Your boiler is fitted with a manual reset overheat thermostat. If
the burner fails to operate and the LOCKOUT indicator light is not
illuminated, check the overheat thermostat by pressing the reset but-
ton. The thermostat is located on the underside of the electrical panel
and is accessible by removing the boiler casing front panel. If the
problem continues after pressing the reset button, consult a service
engineer.
HOW TO OPERATE YOUR
BOILER
If your boiler is being operated for the very first time following
the installation your installer should have commissioned the system
as specified in the Installation Instructions.
