Installation Instructions

FREEZE PROTECTION

FOR EXTERNAL PIPING

IMPORTANT!

With electrical power supplied to the water heater, it will not freeze in environments as cold as -30°F, when protected from direct wind exposure.

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 unit may be drained manually; however, we highly recommend that drain-down solenoid valves be installed that will automatically drain the unit if power is lost.

When the electrical power to the water heater fails, the 3/4″ solenoid valve closes (stopping the flow of water into the heater) and the 1/4″ solenoid valve opens (allowing the water heater and associated piping to drain). Ensure that you run the drain for the solenoids to the outside environment to prevent discharging water inside the building, which can cause water damage.

NOTE: If the unit is installed in an environment that can freeze, follow state and local codes and apply heat trace to ALL water pipes and fittings located outside (attic, crawl space or building structure).
