Gas-Fired Barbeque Grill Cooking Systems

A gas-fired barbecue grill cooking system comprising:

• a firebox;
• a burner assembly mounted within the firebox, the burner assembly having a first burner tube defining a first cooking zone and a second burner tube defining a second cooking zone;
• and
• a gas control assembly having a gas control valve and a control actuator;
• the gas control valve having a manifold, a first valve head, a second valve head, a primary gear, a first secondary gear and a second secondary gear;
• the manifold having a first valve receptacle, a second valve receptacle, and an inlet port, a first outlet port and a second outlet port, the inlet port in fluid communication with the first outlet port and the second outlet port;
• the first valve head, extending into the first valve receptacle, having a first gas flow passage formed therethrough, the second valve head, extending into the second valve receptacle, having a second gas flow passage formed therethrough;
• the first valve head being configured to rotate in response to rotation of the first secondary gear, the second valve head being configured to rotate in response to rotation of the second secondary gear;
• primary gear being configured to selectively engage at least one of the first secondary gear and the second secondary gear;
• wherein the gas control valve is configured, in response to positioning of the control actuator, to selectively control a first flow of gas to the first burner tube and a second flow of gas to the second burner tube such that the first cooking zone and the second cooking zone are operable to be heated independently in a first mode, in which only one of the first cooking zone and the second cooking zone is heated, and heated simultaneously in a second mode.
