how can I stop my ferroli modena 102 pilot light from going out and then coming back on every 10-15 seconds. How do I service this boiler ? What parts would I need? does running sentinel through my radiators help or is it a waste of time? That and many more questions.

right for the three people who have the same problem there is only one of four possibilities firstly and the most common is the fan is not removing the burnt gases quick enough causing the boiler to reach temperature to quickly to check this remove the front combustion cover if it stays on thats your problem secondly change the thermistors thirdly check the air pressure switch(very unusual) and last but not least sometimes the plug which goes on the thermistor is to slack not a good contact

best bet is call out british gas (or ya local boiler man/woman)
