If it is determined that is below the first set value, the combustion control unit 29 feeds back an out-of-fuel signal to the operation control unit 34, and the display unit 35 provided in the operation control unit 34 displays the out-of-fuel signal. Is notified to the user. After a predetermined time has elapsed, the pressure sensor 28
When it is detected that the liquid level H of the liquid fuel in 25 has become lower than a second set value which is set lower than the first set value, the liquid level H becomes lower than the second set value for a predetermined time. It is checked whether the liquid level is lower than the predetermined value, and if it is determined that the liquid level H is lower than the second set value even after the lapse of a predetermined time, the combustion control unit 29 stops driving the electromagnetic pump 30 and stops the combustion.
