In the event of a power failure at temperatures below freezing, the water heater should be drained of all water to prevent freezing damage. The unit may be drained manually or through the installation of the Optional solenoid valves as shown. The electrical connections for the two solenoid valves should be tied to the 120 V power terminals provided on the PC Board of the water heater.When the electrical power to the water heater fails, the cold water supply solenoid valve closes, heater, and the drain down solenoid valve opens, allowing the water heater and associated piping to drain. Ensure that you run the drain for the solenoids per local codes.
