1) The pilot flame is too small. Possibly a build up of debris on the injector.

2) The thermocouple is weak and needing replaced

3) The main gas vavle is needing replaced.

4) There is a problem with the flue. If the terminal is missing or incorrect wind will enter the flue and blow out the pilot.

Try getting the appliance serviced by a Corgi engineer. This should uncover the cause of your problem.
