	Note: Historical data is stored in the CCB's memory. If this
	CCB is replaced during servicing the historical data on the
	CCB being replaced will be lost. The data stored in the new
	circuit board will no longer reflect the entire history of the
	water heater.
	The Elapsed Time, Burner On Time and Cycle Count indicate
	age, usage and wear.
	If the Cycle Count per day is high (divide cycle count by
	days to determine cycles per day) or the cycle duration is
	short (determine burner on time total minutes, divide burner
	on time total minutes by cycle count) consider rasing the
	Differential setting to avoid short cycling and excessive
	component wear, see Operating Set Point And Differential
	Adjustment on page 47.
	This historical data can also be used to assist facilities
	managers in forecasting planned replacement of equipment
	to help avoid lengthy and costly hot water supply interruptions.
