Natural gas, fuel oil(diesel) and propane. Mostly critical condition situations. Propane is only used until the diesel can get online. Usually no more than a 50lb cylinder attached to the system. Primarily if there is a earthquake or some odd disruption of gas service. Same holds with tri fuel generators, except they are natural gas, gasoline and propane. And of course the NOX certs for those as well.
