Method for setting the performance of gas-operated cooking devices as well as a cooking device using this method

A method for setting the performance of a gas operating cooking device by setting a complete combustion of the fuel gas/air mixture supplied to the gas burner of the cooking device. The method includes determining a calorific output of the gas burner and the air ratio required for complete combustion, setting the air quantity supplied to the gas burner dependent on the identified calorific output of the identified air ratio, setting the specific air ratio via a setting of the combustion gas quantity supplied to the gas burner given a constant feed of the air quantity, delivering a combustion gas in a quantity so that the combustion gas/air mixture lies below a lower ignition limit and subsequently raising the amount of delivered combustion gas in steps with further ignition attempts until a successful ignition occurs to acquire the quantity of combustion gas supplied at the ignition point for the combustion gas/air mixture, the calorific value of the combustion gas is obtained from the acquired supply quantity of combustion gas and the combustion gas quantity needed for complete combustion is determined for the obtained calorific value.
