Abstract
An electrically operated line valve has its outlet connected to the inlet of the manifold for supplying the user actuated individual gas burner valves and a user actuated line power switch is closed before opening of any of the burner valves. A valve position detector signals an electronic controller which supplies power to the line switch only if a burner valve has been opened after closing of the line switch. A user actuatable manual override cable enables the line valve to be manually opened during periods of electrical power outage.
