5. Clean the area where the gasket fits to the tank. If
you are replacing the bottom element, remove the
accumulated sediment on the bottom of the tank.
6. Make sure the replacement element has the correct
voltage and wattage rating. Position the new gasket
on the element and insert it into the water heater tank
(Figure 9). Tighten the element by turning it clockwise
until secure.
7. Close the drain valve. Open all hot water faucets
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 constant flow
of water is obtained.
8. Close the faucet and check all connections for leaks.
Check for leaks around the element(s).
9. Connect the electric wires to the heater element.
Make sure the wires are secure and the attachment
points are engaged on the thermostat.
10. Replace the plastic thermostat cover, insulation,
and the access cover(s).
11. Make certain the tank is filled with water. Applying
electric current to heater elements not submerged in
water will destroy them.
12. Restore the electric power supply to the water
heater.
Replacement heating elements must be the same style
and voltage/wattage rating as what is presently found
in the water heater. This information can be found on
the flange or terminal block of the element or on the
unit rating plate.
1. Shut off electric power to the water heater.
2. Drain the water heater as directed under “Draining
and Flushing.”
3. Remove the access cover and fold the insulation
outward and away from the heater element(s).
Remove the plastic thermostat cover from the
thermostat, making sure to disengage the attachment
point from the thermostat.
4. Disconnect the electric wires from the heating
element (Figure 8) and remove the screw-in elements
by turning the element counterclockwise with a 1-1/2
inch socket wrench. Remove the existing gasket.
