5. Clean the area where the gasket fits to the tank. If

you are replacing the bottom element, remove any

accumulated sediment on the bottom of the tank.

6. Make sure the replacement element has the correct

voltage and wattage rating by matching it to the rating

plate on the water heater. Position the new gasket on

the element and insert it into the water heater tank

(Figure 16). Tighten the element until it is secure by

turning it clockwise with a 1-1/2 inch socket wrench.

7. Close the drain valve. Open the nearest hot water

faucet and allow the tank to fill completely with water.

To purge the lines of any excess air and sediment,

keep the hot water faucet open for 3 minutes after a

constant flow of water is obtained.

8. Check for leaks around the element.

9. Reconnect the electrical wires to the element and

securely tighten the screws. Replace the plastic

thermostat cover making sure the attachment points

are engaged on the thermostat.

10. Replace the access cover.

11. Make certain the tank is filled with water. Applying

electric current to heater elements not submerged in

water will destroy them.

12. Reconnect electrical power to the water heater.
