The water heater should be drained if being shut down during freezing temperatures. Also, periodic draining and cleaning of sediment from the tank may be necessary.
1.Turn off the gas to the water heater at the manual gas
2.Open a nearby hot water faucet until the water is no longer hot.
3.Close the cold water inlet valve.
4.Connect a hose to the drain valve and terminate it to an adequate drain or external to the building. (Make sure all connections are tight and that the water flow is directed away from people.)
5.Open the water heater drain valve and allow all the water to drain from the tank. Flush the tank with water as needed to remove sediment.
6.Close the drain valve, refill the tank, and restart the heater as directed by the lighting instructions on the front of the water heater.
If the water heater is going to be shut down for an extended period, the drain valve should be left open.
IMPORTANT: Condensation may occur when the cold tank is first heated and should not be confused with a tank leak.
Never use this water heater unless it is completely full of water. To prevent damage, the tank must be filled with water. Water must flow from the hot water faucet before lighting the water heater. NOTE: The hot water faucet used should be the one furthest from the water heater.
To fill the water heater with water:
1.Close the water heater drain valve.
2.Open the cold water supply shut off valve to the water heater.
3.To ensure complete filling of the tank, allow air to exit by opening the furthest hot water faucet. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping.
4.Check all new water piping for leaks. Repair as needed.
