Claims (1)

[Scope of utility model registration request] Gas is supplied to the gas burner through a plurality of gas circuits with different amounts of gas passing through, and a solenoid valve V is connected to the gas circuit.
In a gas control device, a plurality of solenoid valves _V1 to _Vn are _inserted separately and the solenoid valves are opened individually to set the amount of gas supplied to the gas burner in a stepwise manner _. Operation switches S ₁ to _{S n} are provided to open and close each separately, and the amount of gas passing through a gas circuit equipped with one solenoid valve Vj is set to a gas amount suitable for ignition, and the valve opening signal of each operation switch is used to set the amount of gas passing through the gas circuit to a gas amount suitable for ignition. An ignition device 5 is provided which is in an operating state, and a switching means 6 is provided which is in an operating state while the ignition device 5 is in operation in response to a valve opening signal from an operating switch other than the operating switch Sj corresponding to the solenoid valve Vj. 6, in the operating state, the electric circuit to the solenoid valve Vj is made conductive regardless of the signal from the operation switch Sj, and the electric circuit to the other solenoid valves is cut off, and conversely, the electric circuit to the other solenoid valves is cut off, and the In the stopped state, the gas control device is set so that the electrical circuit connection state corresponds only to the signal state of each operation switch.
