Due to safety considerations, the complexity of the components involved, as well as the level of disassembly required, we don’t allow conversions or provide conversion kits. Converting a Weber grill will actually void the warranty on the unit and might create an unsafe situation.
We do sell most of our gas grill models in both a propane version and a natural gas version, so if you're planning on purchasing a new grill, please make sure that you're selecting the appropriate model for the fuel type you plan on using.
We are very sorry for any disappointment this may cause, but the safety of our fans always comes first. You can read more about this in our blog on the subject here.
