Running a low volume of water through the water heater to prevent freezing

If the temperature exceeds the ability of the water heater to freeze protect itself, or if power is lost, the following steps may prevent the water heater and external piping from freezing. (Units connected with MSA or EZConnect should be drained to prevent freezing if not in use.)

1.Turn the water heater off.

2.Close the gas supply valve.

3.Reduce the flow to about 0.1 gal/min or to where the stream is about 0.2 inches thick.
