Abstract: A conversion assembly for converting a gas burner of a multi-burner gas operated cooking range of a recreational vehicle to an electric burner for operation by the electrical generator of the vehicle or by an external campground electrical power supply so that the range is both electrically and gas operable includes an electric heating element sized for insertion into the recess of the recreational vehicle range deck in place of a removed gas burner, an electrical control mountable on the range control panel in place of the removed gas control valve of the removed burner and a spring clip engageable with a radial support for the heating element for securing the element in the recess. A threaded plug is provided for plugging the hole in the range gas line left by removal of the gas control valve. A cover is provided for placement over the electric control for preventing spillage from damaging the control and wiring thereof.
