置。 In a device equipped with a capacity switching valve that changes the combustion capacity by increasing or decreasing the number of burned burners, and a proportional control valve that controls the gas pressure supplied to the burner, the gas when the minimum input is given to the proportional control valve at the minimum capacity. A combustion device characterized in that the pressure is set to a minimum gas pressure, and means is provided for limiting the input to the proportional control valve for each capacity so that the pressure does not fall below the minimum gas pressure.
