Publication number: 20230250965Abstract: A system for igniting a grill can include a solenoid valve, a flame rectification sensor, an igniter, and a control circuit connected to the solenoid valve and the flame rectification sensor. The solenoid valve controls flow of gas to the grill's burner and includes a switch that closes when a handle connected to the switch opens the solenoid valve. The control circuit sends current to the solenoid valve when the switch is closed to hold the solenoid valve open. After the switch closes, the igniter is ignited. After ignition, the control circuit monitors the presence of a flame with a flame rectification sensor. If no flame is detected after a certain amount of time, the control circuit stops sending current to the solenoid valve to close the solenoid valve.Type: ApplicationFiled: April 19, 2023Publication date: August 10, 2023Inventors: John T. FRENCH, Randall Lee DAWSON

Patent number: 5553603Abstract: A sealed-combustion chamber fireplace includes a combustion air to fuel adjustment device comprising an primary air-fuel mixing body having a fuel source inlet at one end and at least one combustion air inlet port disposed through a wall portion of the body. The air-fuel mixture body may be configured in the form of an air-fuel venturi, burner tube and the like to effect mixing together of the air and fuel to form a combustible air-fuel mixture. An air inlet port cover is movably disposed adjacent the air-fuel mixing body and forms an adjustable air combustion aperture by placement of the cover adjacent the air inlet port. Movement of the cover about the body effects opening or closing of the aperture, thereby effecting adjustment of the primary air to fuel ratio of the air-fuel mixture combusted in the combustion chamber.Type: GrantFiled: April 25, 1995Date of Patent: September 10, 1996Assignee: Superior Fireplace CompanyInventors: Samir E.
