Burnham V13AT boiler

What is the right nozzle for my V13AT boiler? The oil GPH is .75, water MBH is 76.5

    Depends on what burner you have. The oil pressure adjustment also comes into play

    There's more to changing a nozzle than changing a nozzle.

    Is the burner a Sunray, Wayne, Carlin or Beckett? All four have been used on V-1 series boilers.

    Do you have a way to test the combustion results after you change the nozzle?
    Assuming you are a qualified professional with the proper instrumentation to check the combustion results after replacing the nozzle, this is what Beckett publishes on the V13 boiler if it is equipped with a Beckett AFG burner.

    you can look here for the same results
    If you are a DYI mechanic, I urge you to get someone with experience on oil burner adjustment with the proper combustion analyzer.

    if your boiler is equipped with a different burner, then don't read this post, it may be all wrong!

    The best answer for someone who has to change a clogged nozzle but isn’t going to be able to adjust the combustion knowledgeably is “use the same as the nozzle that’s in it now” the same flow rate, spray angle, droplet pattern, and brand. Make sure the burner end cone, blower wheel and air inlet slots are clean. Check to make sure the electrodes are still sharply well pointed. If they’re burned back to a rounded end they need to be changed, If you’ve never done it it’s not difficult but if you don’t position them accurately you can cost yourself more oil than the price of a service call.
