Abstract
Safety and stability of combustion are improved by a combustion controlling device that controls the operation of 2 or more burners and stops all the operation of the burners when combustion states of the burners satisfy a predetermined condition, and the predetermined condition includes a first shutoff condition for stopping the operation of the burners at the time of an initial startup to ignite a desired burner from a state in which none of the burners is ignited, and a second shutoff condition for stopping the operation of the burners in a normal operating state after the desired burner has been normally ignited by the initial startup.
