Sorry my bad, I've spent a LOT of unnecessary money because I used BG14 Banjo burners, I'm only trying to prevent someone else from doing the same. It's not that the bg14 banjo burners will not work on low pressure LP just don't expect them to put out the rated BTUs. I have a 10 gallon system, it would take close to an hour to get 13 gallons of 160 degree wort to boil, that's just too long.
I will post my results of my upgrades this Sunday as I'm brewing tomorrow, hopefully everything works out. I've ordered a jet burner so in can test a different burner, if it works better then expect to see two bg14 banjo burners come up for sale.
My upgrades consist of plumbing my regulator, which is a duel stage low pressure 1/2" outlet 200,000 BTU regulator, directly to my gas rail as close to the honeywell valve as I can as well as making the burner supply 1/2" ID lines as short as possible.
