Abstract: The method detects the quantity of gas to remove the risk of explosion and pollution from remaining gas in the combustion chamber, also controls a burner motor (BM) for driving according to the quantity of gas. The apparatus comprises: a gas quantity sensor section (14) which detects a gas quantity by electric signal; a gas quantity output section (15) which compares the output signal from the sensor (14) with the reference voltage and sends the detection information to a micom.; a sensor driver (13) which supplies/cuts off a driving source for the sensor section (14) and the output section (15).
