    Go to combustion 101.

    Start with your electrode settings, then your combustion air. 



    By sooting up, is it oily with coke on it or is it heavy powdery soot.  There is a difference.  Oily coke is a sign of unburnt fuel or incomplete combustion.  In that case I would look at the electrodes or a fouled nozzle.  If it is heavy powder soot, then look at the combustion air.



    What did the your combustion test numbers look like?  What was the smoke?
