Installation & Servicing
Check the main burner responds correctly to manual on/off operations of
any controls fitted in the gas control circuit.
Check the operation of the flame failure safety system by lighting the
boiler and then turning the gas inlet cock off.
The Burner On light will go out and the controls will try to relight the
boiler. After a period of about 5 seconds, the Lockout light will be
illuminated.
Turn on the gas cock again and press in and release the Lockout button.
The boiler will relight.
ROUTINE OPERATION
Full instructions covering routine lighting and operation of the boiler are
given on the Lighting and Operation Instruction Label located on the inside
of the casing door.
Draw the attention of the boiler owner or his representative to the Lighting
and Operating Instruction Label on the inside of the casing door. Give a
practical demonstration of the lighting and shutting down of the boiler.

are adjusted and used.

IMPORTANT.

maintenance and cleaning, at least annually, in order to ensure reliable
and efficient operation. Regular attention will also prolong the life of the
