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 affi xed
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 Repair Parts
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.

the water heater.

NOTE: The cold water supply valve must be left open when the
water heater is in use.
13. To insure complete fi lling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to run until
a constant fl ow 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 fi lled with water. Water must fl ow 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 fi rmly against the surface
of the tank.
