Does anyone know why an Riello RDB boiler would suddenly start pluming black smoke? Does it have anything to do with the needle valve in the fuel pump?

Have you been fiddling with the pressure regulator?
Pluming black smoke can be caused by a number of things. When was it last serviced? Has anyone been playing with it?

The longer it smokes black the more expensive it is to repair. That's how I work it.

Sounds like somebody's been fiddling! Run out of fuel?

I wholeheartedly agree mate, if left unattended this will cost more than a routine service.

Definitely, absolutely hate a sooted boiler, especially a steamer and even more so if it's been a case of somebody fiddling.

A sooted up toaster is bad enough, a sooted up steamer secondary HEX thats got the soot wet and set is horrible.

Ok. I suggest getting a reputable engineer in out to service it and give everything a look over.
Have you had a recent delivery of oil?

it seems to be getting too much oil to burn either the solonied is not shutting or the needle valve on oil pump is faulty or sticking its a fairly new burner probably 18 months old this behavior started very suddenly according to the owner
