WARNING: Failure to drain the water heater can cause serious damage to the water heater as well as personal injury.

NOTICE: DO NOT unplug the electric power supply cord for freeze protection.

Freeze Protection

Where the water heater may be exposed to freezing conditions, even for a short period of time, be sure to drain all water from the unit as instructed above.

Exposure to freezing conditions can occur from down draft of venting system or from installation in areas exposed to cold air.

The water heater is equipped with a Freeze Protection Electric Heater. As long as electricity is supplied to the water heater, it prevents freezing inside the water heater down to an ambient temperature of approximately minus 20°F (-28°C) (without wind conditions).

This device only protects the internal components of the water heater. It does NOT protect piping and valves. Therefore, piping and valves should be wrapped with insulation material as instructed on page 24.

Another method of freeze prevention is by running a small volume of water. Running water will protect the water heater, piping and valves.

Follow the steps below to ensure proper water flow through the water heater and piping:

Turn off the switch on the remote control.

Close the gas shut-off valve.

Open the hot water faucet slightly until a stream of approximately 1/8” (.32 cm) is flowing. Be sure to check the flow periodically.
