WARNING
DANGER
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 con-
nected with EZ Connect (2-unit link) should be drained to prevent
freezing if not in use.)
1) Turn the water heater off.
2) Close the gas supply valve.
3) Turn on a hot water tap to flow water about 0.1 gal/min or
where the stream is about 0.2 inches (5 mm) thick.
When the water heater or external piping has frozen
1) Do not operate the water heater if it or the external piping is
frozen.
2) Close the gas and water valves and turn off the power.
3) Wait until the water thaws. Check by opening the water supply
valve.
4) Check the water heater and the piping for leaks.
