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.
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.
Figure 7 - Heating Element Detail
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 gasket seats
properly.
NOTE: Repeat Steps 3 - 6 as Necessary for Multiple Elements
Step #8
- Open the main cold water inlet. If the water heater has
been isolated from the system, open the valves. Refill the tank with
cold water. Open a hot water faucet high in the system to bleed
any air pressure from the system. Water will flow freely when air is
completely bled.
When filling the water heater, open a hot water tap to release
air in the tank and piping. The tank must be full of water before
the heater is turned on. Failure to ensure the water heater is full
before turning it on will result in damage to the water heater,
and could result in property damage, serious personal injury, or
death. Such damages ARE NOT covered by water heater warranty.
STEP #9
- Pressure check the tank for leaks around element. If no
leaks are found, use a Phillips Head screwdriver to connect the
wires to the element.
STEP #10
- Turn power back on to the water heater.
Failure to refill the tank before restoring power to the water
heater will result in damage to the heating elements and property
damage. Such damages ARE NOT covered by warranty.
