Banjo burner

Question, I have a bayou classic banjo burner, the manufacturer claims it cannot be used with natural gas. Blichmann has a floor and the top tier burner that is the same burner and has the natural gas conversion kit, which is just the natural gas orifice. I installed this on the banjo burner and no problems. 10 gal hose water about 65 degrees to boil in 40 min. So what is the deal with all the other banjo burners out there that "cannot be converted for natural gas"? My grill is a dual fuel, just change the gas orifice and use NG. You don’t change anything else. Anyone else do this or am I the only one?

yep, its common around here to use the "cannot be converted for natural gas" banjo's for natty gas....I just drilled out the orifices a little at a time till the flame looked good
