Maintenance
WARNING
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: Ensure thread and opening are completely
free of debris. Use a nylon brush to clear away any
debris.
Step 5: 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 6: 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.
Step 7: 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.
WARNING
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 8: 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 9: 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 element and
property damage. Such damages ARE NOT
covered by warranty.
Draining and Flushing the Water Heater
CAUTION
Risk of Shock- Shut off power to the water
heater before draining water.
DANGER
Risk of Scald - Before manually operating
the relief valve, make certain no one will be
exposed to the hot water released by the
valve. The water drained from the tank may
be hot enough to present a scald hazard
and should be directed to a suitable drain
to prevent injury or damage.
A water heater's tank can act as a settling basin for
solids suspended in the water. It is therefore not
uncommon for hard water deposits to accumulate
in the bottom of the tank. To clean the tank of
these deposits, it is recommended to drain and
flush the water heater tank once a year. To drain
the water heater, follow these steps:
1. Turn off power to the unit. The electric heating
elements will become damaged if operated
without water.
2. Attach a garden hose to the drain valve located
at the bottom of the unit and direct that hose to
a drain. 3. Turn off the cold water supply.
4. Admit air to the tank by opening a hot water
faucet or lifting the handle on the relief valve.
5. Open the drain valve or plug.
