C. Heating Element Replacement Procedure
If heating elements need replacement, it is very important to use
the same voltage, wattage, and construction. The element sheath
must be incoloy and the hex plug must be made of stainless steel.
STEP #1 - Turn off power to the water heater. Use a Phillips Head
screwdriver to remove the wires from the element.
Failure to disconnect the power from the water heater before
attempting heating element replacement will result in property
damage, severe personal injury, or death due to electric shock.
STEP #2 - Run hot water at a faucet in the system. When it runs cold,
shut off the faucet. Then shut off water at the main cold water inlet
or, if possible, valve off the water heater from the system. Drain the
water from the system, or just the water heater if it can be isolated
from the system.
Completely drain the water heater before removing and replacing
a heating element or elements. Failure to do so will result in a
leakage of water and property damage, and could possibly result
in moderate to severe personal injury or death.
Water drained from the water heater may be scalding hot. Take
care to avoid scalding. Wear gloves and safety glasses, and direct
water to a safe drainage location. Failure to comply with this
warning could result in property damage, severe personal injury,
or death.
DO NOT replace heating element with a generic heating element.
Only Westinghouse heating elements are approved for use with
this water heater. Failure to follow this warning will result in
premature product failure and VOID the warranty.
Step #3 - Remove the element with a 1 1/2" socket wrench or
element tool.
Step #4 - Inspect the removed element. Determine whether the
replacement element will need a square or circular gasket and
washer.

Step #5 - Ensure thread and opening are completely free of debris.
Use a nylon brush to clear away any debris.
Step #6 - Put a small amount of NSF approved lubricant and sealant
on the appropriate gasket and/or washer for the installation. Put the
gasket and/or washer on the element.
Step #7 - Screw the element clockwise into the tank, and tighten
with the 1 1/2" socket wrench or element tool. Be sure O-ring seats
properly.
