Oil Burner BANG! on start.

No, Its swinging. Its hard to explain really, basically it sits on these little bends in the metal. But over the years it has worn out a bit. The screws stop it from sliding up and out of its little tracks. I have been watching it flap open and closed when it starts / stops and it looks ok.

    I have what I think is called in the field a HARD START issue with my oil burner. It does it about 4 out of 5 times or so. There seems to be too much fuel in it when it lights. It only started to do this after it was serviced. What is the likely cause of this? Nozzle size was the same as what came out they told me. They did adjust the distance of the electrodes and they did some other adjustments when they pulled the burner out but they did not write them down.

    Bang is Not Good ,Chaz. *~/:)

    trust me,you need to give them a call tell them that you are needing to know the stack temp and oil pressure and co2 readings the last time they came out. then you need to say that you require them to come back by (as evidently you have noticed that the system starts with a bang )and you are certain Bang is not good. who knows maybe a part failed unlikely buh it could happen. i hazard that it is a leaky nozzle as a guess.

    It is a Slant Fin Liberty Circa 1991. Its a 120K BTU, not sure of the exact model. It has a Beckett Oil Burner on it.

    I will call them today to have them out. I think I may actualy have the readings. Ill post them when I find the paper.

    Is it a Beckett AFG? Nozzle about 1 gph?

    Yes, I beleive it is an AFG. I dunno what the nozzel size is. The Oil company at this point thinks Im nuts cause I call them so much. In actuality, this is my third call. The first one was for some leaky valves that they replaced. After they replaced the valves I had pressure issues and called them back. I subsequently fixed the pressure issue myself by adjusting the autofill..

    I want to upgrade the controls to something a little smarter and replace onbe zone with cast iron and add an indirect hot water heater with a circulator etc.. They think Im bonkers.

    Any good plumbers in Danbury Ct?

    I feel a bit stupid but all it was was the damper. It was stuck. The service guy stuck a couple of screws in it and said it should be fine now.

    Doh!

    Thanks Everybody!

    Uhhh, Chas

    This damper is the swinging disc in the smoke pipe, right? Why did he stick a couple of screws in it, to hold it closed? If so, that's wrong and you could still have a dangerous condition- get a REAL pro in there.

    Well, It probably needs replacing. They sure dont like to put new parts on when you have a service contract though. Doesnt someone make this out of stainless? Like I said earlier, its a nice little boiler. Id like to upgrade the controls and get an electric damper etc. I really want a new Indirect too. Just cant seem to find a company to do the work.

    auto fill

    before you adjusted the boiler feed , was the pressure too high, or too low ?

    Boiler Feed

    The pressure was a bit too high. It was 16 - 19 PSI. I got it down to 15 - 17 PSI. I used the guage on the front to do it but the tech had one of those hose mounted ones and he was getting similar readings.
