Replacement heating elements must be of the same

style and voltage/wattage rating as the ones originally

in the water heater. This information can be found on

the fl ange or terminal block of the element or on the

water heater data plate.
1.  

Turn off the electric power to the water heater.

2.    Drain the water heater as directed under “Draining

 

 and Flushing” section.

3.    Remove the access cover(s), then remove the insula- 

 

 tion and element cover(s). Remove the plastic guard  

 

 covering electric wiring.

 

 

4.    Disconnect the electric wires from the heating

 

 element (See Figure 13). Remove the screw-in 

 

 element by turning the element counterclockwise  

 

 with an SAE 1-

1/2

 inch socket wrench or use an ele- 

 

 ment wrench. Remove the existing gasket.

5.    Clean the area with a soft cloth to remove any debris  

 

 where the gasket fi ts to the tank. If replacing the bot- 

 

 tom element, remove the accumulated sediment on  

 

 the bottom of the tank. Refer to “Draining and Flush- 

  

ing.”

6.    Make sure the replacement element has the correct

 

 voltage and wattage rating. Lubricate the new gasket  

 

 with a few drops of dishwashing soap, position the  

 

 new gasket on the element and insert it into the water  

 

 heater tank (See Figure 14). Tighten the element by  

 

 turning it clockwise until secure.

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

 

 faucet and allow the tank to fi ll completely with

 

 water. To purge the lines of any excess air and

 

 sediment debris, keep the hot water faucet open for

 

 3 minutes after a constant fl ow of water is obtained.  

 

 Close the faucet.

8.    Check for leaks around element(s) and other connec- 

 

 tions.

9.    Connect the electric wires to the heater element.

 

 make sure all wires are secure. Reinstall plastic guard  

 

 covering wiring.

10.  Replace the insulation and access door(s).

: Operation of this water heater without 

access doors or insulation could result in much higher

temperatures than the desired set point, increasing the

risk of scald injury. Do not operate water heater with the

access doors or insulation removed.

11.   Reconnect the electric power to the water heater. 
12.   Turn the electrical power on to turn the water heater  

        on.  NOTE: the water heater will conduct a system  

 

 diagnostic prior to operation.
