Anode Rod.
The anode rod is a sac-
ri
fi
cial metal rod that helps reduce
corrosion and premature failure (leaks)
in the tank. The anode rod is a consum-
able item. Inspect the anode rod a er
the
fi
rst six months of opera on when
you drain and
fl
ush the tank. Replace
the anode rod if it is substan ally worn
out or depleted. Therea er, inspect the
anode rod annually or more frequently
if needed. If you use a water so ener,
your anode rod will deplete faster than
normal. Inspect the anode rod more
frequently, replacing the anode rod as
needed. Obtain new anode rods from
your local plumbing supplier or have
a quali
fi
ed person replace it. (Anode
rods are a consumable item and are not
covered under warranty).

If the sediment was present
when the tank was drained,
fl
ush the tank by opening the
cold water supply valve and le ng the
water run un l no more sediment
drains from the tank. Close the drain
valve when you are done.
NOTICE:
Do not turn power back on
un l the tank is completely full of
water. For complete instruc ons on
fi
lling the tank, follow “Step 10:” in the
Installa on sec on.

Re
fi
ll the tank by opening the
cold water supply valve. Make
sure a hot water faucet is
open and the drain valve is closed.
Allow the hot water to run full for at
least three minutes to make sure the
tank has all the air removed and is
completely full of water. Failure to
perform this step can cause the upper
hea ng element to burn out. Once you
are certain the tank is completely full
of water, close the hot water faucet.

Restore power to the water
heater. It may take two hours
for the tank to heat up.
Replacing the Hea ng
