H-Hot works fine but continues to smoke ( blue smoke) for 3 to 4 minutes at each start up and when burner re-fires.
I contacted Roger B but he told me to send him my burner head for check-out. Not practical for a full-timer.
The following have been replaced ; nozzle, filter, fuel solenoid, fuel pump, flame sensor, fuel pressure checked and found at 145 psi.
As a last resort, I borrowed and installed a confirmed working control box and control board.
Still getting smoke for 3-4 minutes.
Has anyone had an issue like this ?
Not sure what else I can do to correct.
Any ideas ?
