Continueing on with my winter tune up on the oil burner, I was wondering if anyone knows the gap setting for the electrodes on the burner unit. It is a 85,000BTU Williamson with a Becket burner (model "A", "AF"). The nozzel is a .75 / 80* 'A'. Just a standard furnace. About 4 years old. I guess I'd like the distance between electrodes and probably the 'set back' from the nozzel. I have the manual but it gives no specs. Thanks a ton. pear4710

For a Beckett AF or AFG the electrode settings would be: 5/16" above the center of the nozzle; 1/16" ahead of the nozzle face; 5/32" gap.
