The burner works as designed



second adjustment & working a bit better, I removed the metal shavings and grit that were still blocking some of the slits (mostly walnut shell particles that were hard to see when not lit, but very evident under flame)



THE FIRST FIRING
the original burner is back in place and adjusted (so glad I was able to keep it) and it works more than satisfactorily for its application , the burner took approx. 20 minutes to achieve 90psi from stone cold , there is 70 lbs. of steel & about 1.5 gal. of working usable water to heat up. although I'm confident this was not a factory build , it WAS built by someone who obviously knew what he was doing , everything is super heavy duty, "HEAVY" & well thought out. judging by some of the build materials I would put the age of this boiler in the late 1950's to early 1960's , the boiler side walls are 3/6" thick & the welded port bungs were done by someone with a high degree of competency. the base plate is 12.5" od & is 9/16" thick on the outer rim & approx. 1/2" thick where the boiler sits.
