• Close the water shut-off valve.

• Find the water drain valve, the water filter and the water drain plug located at bottom of the water heater.

• Using a suitable container to catch the water, remove the water drain plug located at bottom of the water heater, the water drain valve from the base of the hot water outlet line, and the water filter from the base of the cold water inlet line.

• Connect a garden hose to the drain valve in the hot water outlet line and place the other end in a suitable drain. Open the drain valve until all the water has drained from the water heater. Leave water heater as is until placed back in service

CAUTION: Even when drained properly, a small amount of water will remain in the water heater. In cold weather conditions, this water can freeze. If this happens, allow the defrost protection on the water heater at least 30 minutes to melt the frozen water. The water heater will not work properly until this water is thawed.

To put the water heater back in service:

Standard Drain Method: Service isolator valve kits may be purchased from the manufacturer, distributor, or place of purchase. The kits include two full-port isolation valves to be used in the inlet and outlet water lines. These kits provide a means for full diagnostic testing and ease of system flushing and draining.

Freeze Protection

Running Water Freeze Protection

WARNING: Failure to drain the water heater can cause serious personal injury from scalding and/or product damage. Whenever the water heater may be exposed to freezing conditions, make sure to completely drain the water from the unit. See "Draining the Water Heater. Freezing conditions come from the ventilation system on direct-vent models and from exposure to cold air on outdoor models. All of these water heaters are equipped with a freeze protection electric heater. This heater prevents freezing inside the water heater down to an ambient temperature of approximately -22°F (-30°C). These temperatures are all based on temperatures without wind. The heater only protects the internal components of the water heater.

NOTICE: Unplugging or disconnecting the power supply to the water heater will also disconnect the power to the freeze protection electric heater. External piping and valves require additional freeze protection. One method is to wrap insulation around the piping and valves. Another method is to turn on a hot water faucet and leave a small amount of water running at a faucet. This will protect the water heater, piping, and valves from freezing.

Vacation and Extended Shutdown

• WARNING: Failure to drain the water heater can cause serious personal injury from scalding and/or product damage.
• If the water heater is to remain idle for an extended period of time, the power and water to the heater should be turned off.
• The water heater and piping should be drained if they might be subjected to freezing temperatures. See “Freeze Protection” section on this Use and Care Manual.
• After an extended shutdown, the water heater’s operation and controls should be checked by a qualified service technician.
