American Standard A-3 Boiler

Hello Everyone

I have an old American Standard A-34 P 1B 31 Series Oil boiler. I think the previous owner had the wrong nozzle installed and now it is not firing correctly, it ignites from time to time. But other times it doesnt. The spark igniters are set correctly.

Would anyone know the ideal nozzle specification for this old workhorse? Gross Output 136MBh Water MBh 102 Firing Rate per Hour 1.35 gallons.

Thank you!

    Sounds like the igniter is going bad. What burner is on this boiler?
