摘要： PROBLEM TO BE SOLVED: To provide a gas combustion device capable of enhancing reliability of correspondence to accidental fire of a burner. SOLUTION: The gas combustion device includes a means 24 for corresponding/confirming the accidental fire. When the burner 1 is in a fire extinguishing state, the means 24 carries out control for forcibly starting a monitoring circuit 33 by a means 22 for forcibly starting the monitoring circuit, if a level of a detection signal of a thermocouple 6 is equal to or lower than a second accidental fire determination value, so as to execute a first accidental fire corresponding/confirming processing for detecting whether a transistor 31 becomes an OFF state of not. If the level of the detection signal of the thermocouple 6 is over the second accidental fire determination value, the means 24 carries out control for turning off the transistor 31 by a forcible off-control means 23 so as to execute a second accidental fire corresponding/confirming processing for detecting whether the transistor 31 becomes the OFF state of not. If the OFF state of the transistor 31 is not detected, the means 24 prohibits ignition processing of the burner 1. COPYRIGHT: (C)2011,JPO&INPIT
