I have a Ferroli F30 about 3-4 years old and just noticed that after the heating system gets up to temp, and the boiler refires up the burners light up as they should but soon after (15-30 secs) they are dropped out again and then relit a few seconds later it is as if the burner is being regulated too low to maintain a flame.... Is this normal ?
I noticed this after replacing the DHW and CH temp thermistor due to poor DWH temperature regulation. The burners also do this when running DHW but again only after the CH and boiler have all got warm untill then the burners appear to regulate fine without going out. I have checked the over temp/safety stat on the boiler heat exchanger pipes and they seem to be fine.
Any help/advice appreciated
