See full text

A controller memorizes an accumulated combustion time by accumulating combustion time of a burner, and is set in a first lower-limit and a second lower-limit higher than the first lower-limit as a lower-limit lower than an initial value of an excess air ratio when reducing an excess air limit of a mixture gas of combustion air and a fuel gas, and the former is the lower-limit in case the accumulated combustion time is under a predetermined set time and the latter is the one in case the accumulated combustion time is the predetermined set time and over.
