PURPOSE: To make it easy to select the position of mounting a manipulation part and to perform adjustment of the amount of combustion and switching of the amount of combustion by providing a control circuit which moves the wick up and down by rotating forwardly or reversely a motor according to a preset motion in response to a key input.
CONSTITUTION: A motor 6 which drives a wick lifting mechanism 3 and can be rotated forwardly or reversely is set through a reduction mechanism, 7 to mesh removably with a gear 4 of a wick lifting shaft 5. A control circuit 8 outputs the output which is beforehand determined according to the content in an input from individual output ports in a microcomputer 8a. Input switches I1WI8 of the microcomputer 8a are connected to input ports I1WI8. By pressing down the key switch, H signal is inputted and by releasing the key switch, L signal is inputted. According to the input of the key a specified output is outputted to the output ports O1 and O2. In a motor driving circuit 20 which drives the motor forwardly or reversely, the motor is driven forwardly or reversely according to the output of the output port O1 and O2 of the microcomputer 8a.
