<P>PROBLEM TO BE SOLVED: To provide a combustion apparatus that can appropriately perform heat cleaning of a CO sensor with a just enough frequency according to actual situations such as degrees of air contamination at the periphery of the installation site of the apparatus or the like. <P>SOLUTION: The combustion apparatus A, which includes the CO sensor Sa for detecting CO concentration in exhaust gas and a control means 2 for controlling the performance of the heat cleaning of the CO sensor Sa at an interval of predetermined hours, or at an interval of the predetermined hours and each time predetermined conditions are satisfied, includes a filter-diagnostic means 20 that can evaluate the clogging condition of an air-supply filter 13 provided for a fan 11. The control means 2 modifies the predetermined hours according to the clogging condition of the air-supply filter 13 evaluated by the filter-diagnostic means 20. For example, in the case where the air-supply filter 13 is easy to clog, the predetermined hours are reduced relative to the case where the air-supply filter is difficult to clog. <P>COPYRIGHT: (C)2013,JPO&INPIT |
