8. Clean the area around the element opening. Remove any
sediment from or around the element opening, inside the
tank.
9. If you are cleaning the element you have removed, do so by
scraping or soaking in vinegar or a de-liming solution.
Replacement elements must (1) be the same voltage and (2)
no greater wattage than listed on the model rating plate affixed
to the water heater.
10. A new gasket should be used in all cases to prevent a
possible water leak. (See Element Gasket in the “Parts Order
List ” Chart). Place the new element gasket on the thread
side of the cleaned or new element and screw into tank,
securing tightly using an element wrench.

11. Close the water heater drain valve by turning the handle to
the right (clockwise).
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.
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.
