@SJB060685 @Best I've spoken with the manufacturer and you are both correct. They said no, that fire board shouldn't be there. It's supposed to be in the base of the combustion chamber. What's likely happened is that it has become dislodged in transit. I'm awaiting a response from the installer to see if either I can push it back down into place, or he can come look at it.
On another note, I had the heating system in for a while there (before I found out about this fire board) and the pressure actually increased slightly. I've not noticed any increase in pressure at all since I noticed the fault, unless I manually did it via the filling loop. I'll keep an eye on how much it drops over the next hour or two, then I'll try draining the system and checking the expansion vessel properly. Thanks again!

It was sealed. The only thing in the system that has been replaced is the boiler/burner. Everything else has remained the same. The boiler it replaced was extremely old and very hard on oil. This new(er) boiler is miles more efficient. Probably 3-4 times more I'd say.Registered gas engineer is no good for an oil boiler! Unless they do both.

Was your old system open vented or sealed?
