Help with Burnham V8 issue

GrumblesGrumbles Member Posts: 3
I have a Burnham V8 boiler with a Beckett burner that I have been servicing since I moved into my house a few years ago. The thing has run great since I moved in but this heating season it has started to act up on me and I cant get to the bottom of the issue. About a month into using it this winter it went out on me and since then I can only get it to run for about a week before it goes out again. Every time it goes out I have to bleed it and it cranks right back up again and runs fine till it dies. I changed the nozzle and re-seated the filter to make sure everything looked good on that end and not general tweaking has seemed to make any difference.

    need more information. Inside oil tank?, outside oil tank?, single pipe?, two pipe? Sounds like an oil delivery problem.

    Get a pressure gage and a vacuum gage on the pump and we can help you troubleshoot

    Sorry busy end of the week, I couldn't get back to this before now. Its an inside tank. Delivery line is under the slab. Singe pipe. I have to get a some gauges that will fit and I can test. I think its a vacuum seal issue so the pump looses its prime when off too long. The house also uses wood to heat so sometimes it can take awhile before there is a demand for the boiler.

    I would test the fuel line first before blaming the fuel pump. More likely a vacuum leak in the line before bad pump seals.
    Both can be tested with pressure and vacuum gauges.

    Eliminate the oil line under the slab. Unless its sleeved, and if it leaks, you're asking the EPA to knock on your door. Run a new exposed, coated oil line.

    So I don't seem to have the right fittings on my pressure and vacuum gauges for this boiler. I haven't hooked them up to this one before and it seems to be a different size than the last boiler I had. I have some adapters ordered and am waiting. In the meantime I ran into a friend who services boilers and said he was willing to bet it was a tank issue and that I just have sludge built up in the tank outlet and that I should blow it out with low pressure air through the bleeder at the tank. I gave that a try and am waiting to see if it craps out on me again. I will update when I can hook my gauges up to it. The oil line appears to be sleeved, or it is at both ends. Not excited to deal with it if it is a leak in the line since the line goes from one corner of the house to the other.

    More than likely the line under the floor is plugged up. If the tank is on the same level as the burner it should flow gravity if there is a reasonable amount of oil in the tank.
