11.Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater.

12.Open the cold water supply valve to the water heater.

NOTE: The cold water supply valve must be left open when the water heater is in use.

13.To insure complete filling of the tank, allow air to exit by opening the nearest 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.

Never use this water heater unless it is completely full of water. To prevent damage to the tank and heating element, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” power. The manufacturer will not warrant any elements damaged by failure to follow instructions.

14.Check element for water leaks. If leakage occurs, tighten element or repeat Steps 2 and 3, remove element and reposition gasket. Then repeat Steps 10 through 14.

15.Reconnect the two wires to the element and then check to make sure the thermostat remains firmly against the surface of the tank.
