Installation Instructions
Attach a hose to the water heater
drain valve and put the other end in
a floor drain or outdoors. Open the
water heater drain valve. Open a
nearby hot water faucet which will
relieve pressure in the water heater
and speed draining.
Check again to make sure the electrical supply is
turned “OFF” to the water heater. Then disconnect
the electrical supply connection from the water
heater junction box.

a. If you have copper piping to the water heater, the
two copper water pipes can be cut with a
hacksaw approximately four inches away from
where they connect to the water heater. This will
avoid cutting off the pipes too short. Additional
cuts can be made later if necessary. Disconnect
the temperature-pressure relief valve drain line.
When the water heater is drained, disconnect the
hose from the drain valve. Close the drain valve.
The water heater is now completely disconnected
and ready to be removed.
b. If you have galvanized pipe to the
water heater, loosen the two
galvanized pipes with a pipe wrench
at the union in each line. Also
disconnect the piping remaining to the
water heater. These pieces should be
saved since they may be needed
when reconnecting the new water
heater. Disconnect the temperature-
pressure relief valve discharge pipe.
When the water heater is drained,
disconnect the hose from the drain
valve. Close the drain valve. The
water heater is now completely
disconnected and ready to be
removed.

Removing the Old Water Heater
WARNING
The water passing out of the drain valve
may be extremely hot. To avoid being
scalded, make sure all connections are
tight and that the water flow is directed
away from any person.
CAUTION
Mineral buildup or sediment may have accumulated in
the old water heater. This causes the water heater to be
much heavier than normal and this residue, if spilled out,
could cause staining.
