Problems with BF3...

in Oil Heating
Just about every part on this burner has been changed.  New motor, control, valve stem, coil and nozzle.  The burner starts up fine then every now and again the flame will immediatly drop out and come back on 10 seconds or so later.   I went through the reillo troubleshooting check list and everything checked out fine.   It has an ET-25 post purge controller on it and I'm not too familiar with them.  Could this be causing the flame drop out?  I used an oil watcher and saw no bubbles and vacuum reading was fine.  Any input would be appreciated.



Thanks.

    cad cell

    Neat trick i learned is to lay a Honeywell cad cell assembly in the air tube and run the leads out to where you can read it with an ohm meter. this will tell you if the flame is stable. Also allow you to set the burner up to the lowest cad cell reading by adjusting intake air/fuel pressure/ head position. Then do a combustion test and go from there. If the cad cell reading is too high the control will go into recycle and keep turning the burner on and off.
