During the operation of combustion, when the test switch(TSW) is on, the micom(10) is sensed the detecting mode of inflammation voltage for inspecting the burning condition. While the weak burning condition is set by the control of heat power setting switch(VR), the micom(10) estimates if the voltage of input port(PI3) input through the heat power setting means(12) is the setting of weak burning. If the inflammation voltage of weak burning is detected, the low level signal is output to the output port(PO2) of indication means(13) so as to turn on the ventilating lamp(L2). While the strong burning condition is set by the control of heat power setting switch(VR), the micom(10) estimates if the voltage of input port(PI3) input through the heat power setting means(12) is the setting of strong burning. If the condition is strong burning, the input through the inflammation voltage sense means(14) is detected, then is checked the inflammation voltage according strong burning. When the inflammation voltage according strong burning is detected, the low level signal is output to the output port(PO2) of indication means(13) so as to turn on the ventilating lamp(L2).
