Boiler pilot light keeps going out help!!!!!!!

[dp.simpson]

Hi I have recently had my boiler moved and a new shower and sink put in close by. After the plumber who reinstalled the boiler drained the system the pilot light will only stay on for about half an hour. unfortunately my plumber has gone on holiday for two weeks. The pilot is only going out when in central heating mode . any posts would be gratefully accepted as it is really bloody cold up north!
Many thanks Paul( boiler is ravenheat csi 85a)

Your boiler does not have a pilot light but the burner itself will go out when boiler is up to temp,this is probably what it is doing after half possibly because of air lock in the system preventing the circulation of the hot water to the rads.
