    I'm no burner man but

    I am a plumber/pipefitter and sub out the burner work, but when the fuel source is in question you can prove it by supplying the boiler with a small can and a short tube.

    Need more info. Oil coming out of nozzle line? Air setting? (to far open) Ignitor working? Proper nozzle in and tight? Electrodes set properly? etc.

    How Old

    How old is this Vitorond 100 ? A couple of years ago now they had some big issues with the NX burner. Does your boiler have the stainless steel insert for the combustion chamber ?  You could always contact RW Beckett.
