stream of water to a suitable drain where it will cause no damage.. Leave water heater as is until next use..

To put the water heater back into operation after draining, follow the steps below..

Reinstall the drain plug and water filter.. Close the hot water outlet drain valve..

Open the water shut-off valve and close again after making sure that water comes out from hot water faucets.. (This step is to remove air from the water lines..)

Plug into an electrical outlet, fully open the gas shut-off valve and the water shut-off valve..

NOTICE: The water heater may not operate unless the above procedure is followed correctly..

WARNING: Failure to follow these instructions while draining the water heater can cause serious damage to the water heater as well as personal injury, including scalding.

Optional Maintenance Method

Isolator valve kits may be purchased as optional items from manufacturer, distributor or place of purchase.. They allow for one person full

diagnostic testing and ease of flushing the system..

The kit includes two full port isolation valves, one for the cold side and one for the hot side..

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 heater at least 30 minutes to melt the frozen water or the water heater may not work properly.

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 -30°F (-34°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 23..

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..
