Oil burner rumbling on start up and end

Marilyn_4

Beckett burner with a L 1 air tabulator on the nozzle assembly.3 section Lennox boiler. 1 pipe top feed to burner.



It started as a normal yearly cleaning. Changed oil filter, A strainer, .75 70A nozzle. Removed smoke stack, vacuumed chimney and boiler.



Started her up fine. Upon shut off there was additional oil from nozzle that caused a rumble in the boiler and smoke pipe.



Took out the nozzle to check again and noticed the air tabulator was coming apart. Replaced it with a new L 1. Same thing...extra oil after shut off and rumbling.



Smoke test was clean. Draft over flame was -.02 breach -.04



I moved the nozzle assembly forward which stopped the extra oil and rumbling but then I had a bad smoke reading. Draft over flame was +.03 -.04 breach.



I'm going to call Beckett today to get the right settings.



Any ideas why this would be happening and what I can do to stop it before calling Beckett?



Thanks,

Maz

I have used these with good success on different rumbling applications.

They screw-on in place of the nozzle filter and are sized according to your pumps pressure setting.

These are nozzles that you replace with the Typical Delvan nozzle?

That will cause problems. Where, if any, is the filter located?  Vacuum test?
