Abstract
A dual mode downdraft gas range provides a number of substantial advantages, including operation in a powered burner mode and an atmospheric mode. In the powered burner mode, a plurality of powered open flame surface burners can provide even heat from each of the burners as a result of burner flames that provide substantially complete combustion close to the burner outlets in short, stable flames that are unaffected by an adjacent downdraft exhaust or other outside influences. In the atmospheric mode, the gas burners can operate without a downdraft exhaust. The gas range can meet agency requirements in both the powered mode and atmospheric mode of operation and can be inherently fail-safe in the event of a power failure in the downdraft exhaust system. The gas range can be economically and easily manufactured and assembled, with burner controls arranged for convenient operation at one side of the range box for the plurality of burners.
