PURPOSE: To prevent the local overheating of a cooking vessel even when the number of operated burners is small by a method wherein respective, flame ports of a multitude of burners, which can be on-off controlled independently, are arranged in one plane while the amount of combustion of a range can be controlled by the number of burners burnt at the rated capacities thereof. CONSTITUTION: A range is constituted so that respective fuel gas supplying routes 5 of a multitude of burners 1a-1e are provided with solenoid valves 6 respectively while the opening and closing of these solenoid valves 6 is controlled independently by a control device 7 to control the ON-OFF of the burners 1a-1e. Accordingly, combustion under the rated amount of combustion of a range or the maximum amount of combustion can be effected by burning all of the burners 1a-1e under the rated amount of combustion respectively. The amount of combustion can be reduced stepwise by reducing the number of burners 1a-1e to be burnt. According to this method, the local overheating of a cooking vessel 3 can be prevented even when the number of burners to be burnt is small.
