For my burner I just had some blackpipe with the blower on one end and made a elongated hole about 6" down the pipe so a bent piece of 3/8 pipe with a drilled brass plug soldered into it and drilled out for the orfice would spray down the center once inserted as I did not have a regulator for the propane the theory being the drill size would regulate the gas flow.
