GAS DOWNDRAFT RANGE WITH SELECTIVELY INTERCHANGEABLE BURNERS

摘要

A gas cooking appliance is provided which is operable with interchangeable burners. An appliance housing includes a burner box mounting an upwardly facing non-removable burner pan. A gas supply system includes gas valves arranged to provide gas to inlet fittings having orifice hoods mounted on the burner pan with the orifice hoods and burner pan being adapted to interchangeably receive first and second burners. A proximity ventilation system has an exhaust intake adjacent the burner pan and a motor driven blower for inducing airflow into the exhaust intake. A first switch is mounted on the burner pan and is operated by only one of the burners. A second switch is associated with the gas valves and is in circuit with the first switch. The switches are cooperable on operation of the gas valves to provide automatic blower operation with only one of the first and second burners.
