PURPOSE:To facilitate the operation of a device and also facilitate the assembly of a safety device by a method wherein the control part composedof a motor and a gas pilot change-over switch is electronically controlled. CONSTITUTION:When a high combustion power and ignition button 34 is depressed, a motor 42 is rotated by a gas control part 30 under a control of an electronic control part 31. Then, a closing plug 40 opens, the gas passed from passage holes 43a-43g of a gas flow rate control unit 43 and reached to a gas burner 60 is ignited by an igniter 61. When a low combustion power and ignition button 33 is depressed, a rotary angle of a gas flow rate control unit 43 is confirmed, and the motor 42 rotates adjusting rotation in order that the control unit 43 is adjusted from the high combustion state under an ignition start to the low combustion state of the button 33. When the flame is to be extinguished, the button 32 is depressed to confirm that the control unit 43 and the closing plug 40 are placed at their combustion positions and those positions, and then the control unit 31 rotates the motor 42 and closes the closing plug 40. |
