What does the flow meter alarm set button do? What does 990 mean?

Flow Meter Alarm Button

The flow meter alarm1 set button lets you set an alarm for a volume of water that passes through your heater. The alarm has settings from 10 to 100 gallons. 990 is the default setting, which means that the alarm is off. The flow meter alarm1 does not automatically shut off water flow. It is merely a signal for the user to manually shut off the water.

Additional detail can be found in the owners guide located at http://support.noritz.com/technical-literature.php
