So I'm looking to plumb my rig with NG, and have the hose from the house to the rig. I'm going to be putting the manifold on soon (1/2" iron pipe) and want to know what size to go with on the hose leading from the manifold to the burner. I have 12 tip ~6" diameter NG burners. Also, let me know if anyone has had good luck with a flame control valve, or if a 1/2" NG ball valve will have good flame control. Thanks.
