A:Answer Parts required for propane use do come with it. The gas regulator which comes with it is used for either natural gas (NG) or propane (LP)… the regulator comes setup for NG but to change it for LP use, it's simply matter of opening it, reversing the orifice and closing it back up. It also comes with a selection of orifices suitable for LP use. It's simply a matter of selecting the proper one based on consulting a chart in the instruction manual referencing the BTU output of each individual burner. The orifices simply screw in and out using a small screwdriver.
