1. A gas-operated outdoor grill comprising: a first set of gas nozzles for cooking food; a second set of gas nozzles disposed along the periphery of a grill surface for cleaning the grill, wherein the second set of gas nozzles allow a larger amount of gas flow than the first set of gas nozzles, thereby raising the temperature inside the grill high enough to convert the food residue to ash; a cleaning valve switch which can be positioned between a cook position, in which gas is delivered to the first set of nozzles, and a clean position, in which gas is delivered to the second set of nozzles; and a gas control valve which delivers a variable amount of gas to the first set of nozzles and a fixed amount of gas to the second set of nozzles; wherein, when the cleaning valve switch moves from the cook position to the clean position the gas control valve first opens gas flow to the second set of nozzles, and then closes the flow to the first set of nozzles, by first establishing flow in both the first set of nozzles and the second set of nozzles prior to shutting off the gas to the first set of nozzles the gas from the second set of nozzles is ignited by the already established flame of the first set of nozzles, when the gas control valve completes its full movement gas flow to the first set of nozzles is ceased specifically designed to raise the temperature in the grill sufficient to clean its interior. |
