I've got a fairly new (less than 5 years old), Beckett AFG oil
burner. I bought my house last year and the unit was all sooted up.
My friend, who is a commercial boiler tech, helped me change out all
of the filters, nozzle, electrodes, etc and I brushed and cleaned the
entire boiler. One problem we had last year, was that the unit would
only run with the air supply almost completely closed. Because of
this, the unit ran really rich all winter and I even have soot stains
on my roof. Does anyone know why this unit would shut off when I try
to add air into the mix. I think I was probably throwing money up the
flue so to speak last year.
Y need to get someone out there that cam measure the fuel pressure/flow
rate and otherwise has experience with the Beckett. I spent a week at a
Trane oil furnace school but that was many moons ago and the fuel delivery
suggestion is the only one I can give.
Shut off when the air shutters are opened, or loose flame and then shut
If the former, it makes me suspect a bad or misadjusted safety of some
sort, perhaps a draft sensor or a CAD cell that's misaligned, only
marginally detecting the flame and loosing the detection if more airflow
moves the flame attachment point. If the later, then I'm with the fuel

someone on what to check is fairly useless considering the complexities.
I used to be able to diagnose the Trane units using sight and sound.
