Can't get anyone to service it here on the Isle of Man - heating engineers are not interested unless they installed it or you need a new installation. Serviced it myself last autumn - oil pressure was fine, but I don't have equipment to do a CO2 test. Wondering if it might be a dirty photocell...

Hi all Wonder if anyone has an idea of what is going on with my eccentric Trianco oil boiler - which would have never worked at all if it hadn't been for the help I received on this forum. Thanks to those concerned. Anyway, the thing used to trip the little button under the control box at...

Thanks Tony, I'll give it a go. Cheers

Hello Chaps I have a Trianco Eurostar Combi 70 that was a so-and-so to get sorted last year (thanks to all that helped with advice on that), but I now have a problem with the Boiler Limit Stat cutting in after a few minutes and I have to wait for 10-20 minutes before I can press the button...

Thanks John sounds like a good theory, I'll check it out. Max

Hi Chaps, I finally managed to get my old Trianco Eurostar combi 70 going, but a least once a day the boiler limit stat shuts it down and the button on it has to be pressed. Does the stat need replacing of is something else causing it to trip? Also, anyone know why the DHW doesn't work...

Yes John, the combustion chamber was sooted up. The mixture is set correctly now and running clean. The Trianco manual says a pressure of 130psi but the tech guys at Riello say 8 bar, which, as you know is more like 125psi, coupled with the dubious quality of Manx Petroleum's kerosene and not...

Well then, after replacing almost everything (I even borrowed a control box). The so-and-so still wouldn't work. So, as a last ditch attempt, I stripped down the burner, cleaned everything (again). Noticed there was some soot in the box. Hmm? Could it be that it built up when it was running for...

I like your style John! I'll give that a go. If nothing else, sounds like my kind of fun! Makes sense too! Thanks Max :D :D

Hi Mandate There is evidence that oil is being discharged from the nozzle. As for a spark, with the burner cover off I can see a flash from down the back of the control box coming from up the business end (accompanied with a cloud of dirty smoke every time it tries to start (cough!)...

Thanks for your input John. Baffles were all clean and correct, but I will re do them again as it ran for a week after before this problem occurred so is probably mucky again now. Didn't get a flue analysis done when it ran as I can't find anyone to do it! This Island's a lovely place to...

Finally got the beast to run and was working fine for a week. Last Saturday morning had a lockout. Reset and... no joy. The burner starts and tries to make a flame. Pulled out the burner, cleaned everything, including photocell, reset electrodes, checked fuel flow (fine) back together and it did...

Thanks Oilhead - will do. I still don't understand how the DHW can work if the CH has the flow through the pump. Can anyone enliughten me? Cheers

Hello Folks Finally have my old Eurostar Combi 70 running (oil pressure gauge helped!) but have now discovered that the DHW is not hot when the CH in running. Turn off CH and plenty of hot water. Checking the the electrical connections to the 3 port pump I found that there was 230v on the...

Thanks for the advice. I'll check the pump setting. Cheers.

I thought about bypassing the boiler stat just to check, so I'll give that a go tomorrow (it does click at the lowest position). There is currently no room stat, although the manual says that the connections for one should be crossed if not required, so I'll check that out even though the...

Chapter 2... Pump stripped, all in order, rebuilt and refitted. Took the opportunity to tidy-up some dreadful plumbing (not sure if it was factory stuff) and replace the CH in/out shut-off valves. Anyway, turned the beast on and waited. Nothing, other than the pump cam on as soon as I...

Thanks John, good call. Yep, IOM is a great place to live (unless you want a heating engineer!)

Thanks. I'll strip the pump. I can hear it whirring away, but the impeller could be trashed, I suppose. Also, the body of the pump is getting v.hot. PS. anyone know what the factory setting should be on the oil pressure screw and airscrew. I can't get an engineer to look at it, here on Craggy...

Anyone know what is the correct arrangement of these? Currently cups facing up with a plate on the top ones and three a side in the flue box. Ta.
