My fathers baxi 552 is making a rattling noise and it seems to be coming from underneath the fire.
It only happens when the boiler thermostat is turned up past one.
Any ideas what it might be and how to cure it?

These boilers have flue baffle plates fitted,one across the top and one in the centre of the heat exchanger.It could be that one of them is rattling.If it is them its nothing to worry about just annoying.
