Hi,

There is black smoke/fumes coming from the outside flu when the boiler is turned on. Before we noticed this the boiler seemed to be working ok. Any advise on what the problem could be?

Thanks
Chris

Call a heating engineer urgently. It could be that a service is long overdue, or could be more sinister.
Do not take chances.

You need an RGI ASAP.
