called to a non running delta elite f-25 with beckett afg ,after clean out and tune unit ran fine until it clanged and rumbled then ran fin again,homeowner said unit has done this since install,installer did not fix,while the smoke test was zero that was only with 85% excess air and low co2,i did replace the nozzle with what was in there
a.50 60a but later found it needs a.50 60b,can the nozzle be the root of all these problems
