I could not locate it on the WB site . I think the part number is 7716190003

ok so the boiler is running. However there is still a flue issue. I helped install the flue 8 years ago with my uncle. At the bottom of the boiler there is a metal plate in between the start of the flue and the actual boiler. Exhaust fumes go up the middle round pipe and clean air gets drawn...

it was the original photocell, boiler has not been touched in 8 years. I recon the plumber knacked up on the setting or he tried to up the air settings higher to attempt to compensate for the flue issue. Boiler is running now but probably not at best settings and silver box is off.

unsure of the part number, however it is the same length as the old one as the old one is still here and the plumber showed me the old one compared to the new one.

maybe he has set the psi at 110 psi for 28.5kw thus air setting off 15 was too far out? I assume that would make sense in theory lol

nope but he had a pressure dial thingy on the pump on previous visit. according to the installation manual, if he has tried to set it for 32kw it should be approx. 130 psi and 15 air setting for RS But again I cannot verify that. its a sterling 40 burner

Well seems to be working for the moment , i will come back with the full story once its fixed properly. Thanks to All for the input. I have stuck with this guy because he done the service and was supposed to do the repair. I have only had one engineer to it. the burner has now been working...

That makes sense to me. But i don't understand how plumber did not figure it out. lol

yes he has the kit. he measured pump pressure and used gas analyser last time he was here(when new pump was put on). he never re-tested after he turned the screw down this visit. there is no black smoke and does not stink lol

he has turned the air screw down. ...fired up straight away. Was at 15 unsure what he turned it down too. There is still an issue, said he would have another look after xmas. Could not put the silver box on as it just choked.

But surely when plumber adjusts air/combustion he would know this? Are you saying the Air screw needs turned down??? if that's the case i assume the flame is not burning as hot/consistently and the photocell is not sensing the flame?

That's another half hour running, dropped the boiler thermostat down and it started up as it should when temp dropped. ill let the boiler cool down/turn it off and see what happens.

I have just turned it off ...been running for over 30 mins rads are hot. now turned it back on after a few mins. Requested heat after a few mins and fired up and running again, ill leave it running for a while again.

only restricted air for 20 secs or so then took hand off. ...its still running...can hear burner firing on and off as it gets to temp.

Uncle will not take any money from me. And he is a good distance away. I could have got it serviced free as well but just does not sit rite with me.
