PROBLEM TO BE SOLVED: To solve a problem in which, although it is necessary to set an aperture of a fire power adjusting part to an aperture corresponding to an ignition fire power for a next ignition when an extinction operation is performed, because electrification to a control part is started when an ignition operation is performed if an ignition/extinction operation is manually performed, fire power adjustment is operated by an electric actuator such as a motor, and an actuation power source is supplied by a battery, raw gas is leaked for a longer time period if an origin detecting operation is performed prior to the fire power adjusting operation, and if the ignition operation is performed during the origin detecting operation.SOLUTION: When an ignition operation is performed on an ignition/extinction function in the middle of the drive of a motor toward a stopper, an origin detection of a motor is stopped, and an aperture by the motor is reset to an aperture corresponding to an ignition fire power.SELECTED DRAWING: Figure 5 |
