I am a number 1 muti certificate holder for nat gas, propane, and oil. It means I can work any gas any size. But that is just the theory of how its supposed to work. Unless you have experience working in the field you can get lost real quick! Oh, and I forget stuff sometimes, so you do have to be careful, but thats cause I'm old TOO. IF I had to manufacture fuel lines I had to use (Approved Materials and Methods) if I didn't and someone died because what I did I went to jail. So I suppose all you fellas who built your own fall into that dark hole. BUT I could make any thing that held feon out of copper tubing or brass welded together with silfos or silver solder and they witheld pressures more than 300 lp. without leaks. Hmmmmm. Leak testing with dishsoap and water or store bought stuff was a given on everything made or ajusted and on bigger stuff they required a 24 hr press test at a set pressure. Get a reg that is ajustable and after the leak test is assured start with a very small pressure and see how it runs. every piece of equipment is different even in small ways and careful testing is needed. But when the flame is not sitting just a fraction from the burner or lifting off , your press IS TOO HIGH! And without a proper vent for the burnt gases to go to IT WILL SMELL!!!! Thats why kitchen ranges are limited to below 80 thou btus without a range hood with a sprinkler system to remove the burnt gases, like the ones at macdonalds. But theses are just the mussings of an OL" Fart
