A heater burner capable of automatically controlling a combustion amount is provided that is easy to design and can reliably stop its operation before room air is contaminated regardless of ventilating conditions of the room being heated. <??>The combustion-stop temperature decision means (10) defines a first combustion-stop temperature (Th1) as a temperature obtained by adding a predetermined first addition temperature (AT1) to an initial room temperature (To), a second combustion-stop temperature (Th2) as a temperature obtained by adding a predetermined second addition temperature (AT2), lower than the first addition temperature (AT1), to a set temperature (Ts), and a third combustion-stop temperature (Th3) as a temperature obtained by adding a predetermined third addition temperature (AT3), higher than the first addition temperature (AT1), to the initial room temperature (To). When the room temperature reaches a reference value determined by the combustion-stop temperature decision means (10), the combustion-stop command generation means (12) outputs a combustion-stop command to the control unit (5). Upon receipt of the combustion-stop command, the control unit (5) stops the fuel supply means (2) and the air supply fan (3) to stop combustion. <IMAGE> |
