能とする。The operation of the safety device for a water heater according to the present invention will be described based on the above configuration. When using the water heater, the sequencer 6 synchronizes with the ON of the burner to be operated, and the time measuring unit 4
Is started and the increment of the time measuring unit 4 is stopped when the burner is turned off. Then, the burner using the accumulated time accumulates in the dedicated area of the storage unit 5. In other words, the cumulative time is dedicated to the bath and hot water supply sides. When the integrated value exceeds a predetermined time as the life of the heat exchanger of the water heater, the sequencer 6 prohibits the burner ON processing on the side that has exceeded the cumulative time and disables it thereafter.
