ABSTRACT:
A method for substantially maintaining an average heating temperature over a period of time without the aid of a temperature sensor. The method provides an apparatus which has an ignition device that is adapted to ignite a fuel. The apparatus may be a cooking appliance or practically any other device that is adapted to heat something. The fuel may be natural gas, propane gas, or practically any other fuel that may be ignited to provide heat. Conveyance means are provided for receiving the fuel from a source of the fuel and conveying the fuel to the ignition device. A valve is interposed on the conveyance means between the ignition device and the source of fuel. In order to substantially maintain the average heating temperature over the period of time, the valve is opened and closed in a predetermined pattern such that at least a portion of the fuel conveyed to the ignition device is ignited.
