PROBLEM TO BE SOLVED: To provide a combustion equipment capable of accurately deciding a life of an implement by effectively judging a deteriorating situation of a combustion performance caused by clogging of a vent passage or the like of the implement even when an exhaust tube is extended. SOLUTION: In the combustion equipment comprising a combustion fan 5 for supplying and exhausting, and an air supply amount detecting sensor 23 for directly or indirectly detecting an air flow rate supplied to a burner by the fan to self-diagnose a deteriorated state of the combustion performance of a vent passage or the like of the implement, a criterion for judging the deterioration of the ventilation is corrected before entering the self-diagnosing operation according to an installation length of the means 51.
