When a device is overheated or a room temperature is abnormally increased, the microcomputer receives a signal from a room temperature detecting means 7, and when a room temperature exceeds a given temperature set at the interior of a room temperature deciding means 16, a signal from the room temperature deciding means 16 is inputted to the microcomputer 18. Combustion quantity is limited by means of a built-in heating output limit means 17, a signal is outputted to a combustion quantity limit means 15. As a result, a heating output is decreased to prevent overheating of a device and an abnormal increase of a room temperature.
