Beckett Burner Ignition Transformer melting
I'm sorry I am not familiar with the term refractory. Do yo mean the lining in the chamber? Also according to my friend he has a 12"x 12" duct for fresh air. I mentioned the chimney may be obstructed. He told me he checked and cleaned out the base but maybe the chimney lining is falling apart blocking the flue gases. He had a service tech check it out adjusted air mixture as well as barometric damper. I haven't had a chance to get there yet but something told me experince it has to do with some kind of air or lack of.One other thing to mention he took jacket apart and cleaned out the sections which were plugged solid.Do the air shutters need to be adjusted.What is the ideal color flame for oil burners????
