Co Flexible metal conduit or flexible metallic tubing shall be
permitted for grounding if all the following conditions are
meg:
1 The length in any ground return path does not exceed
6 feet,
2,, The circuit conductors contained therein are protected
by overcurrent devices rated at 20 amperes or less.,
3 The conduit or tubing is terminated in fittings
approved for grounding.
For complete grounding details and all allowable exceptions,
refer to the current edition of the National Electrical Code,
4. A standard W' conduit opening has been made in the water

_IWARNING
WATER HEATERS EQUIPPED FOR ONE VOLTAGE
ONLY: This water heater is equipped for one type voltage
only. Check the rating plate near the bottom accesspanel
for the correct voltage. DO NOT use this water heater
with any voltage other than the one shownon the model
rating plate. Failure to use the correct voltage can cause
problems which can result in DEATH, SERIOUS BODILY
INJUR_, OR PROPERTY DAMAGE. if you have any ques-

_i, CAUTION
If wiring from your fuse box or circuit brealter box was
aluminum for your old water heater, replace it with cop-
per wire° If you wish to reuse the existing aluminum wire,
have the connection at the water heater made by a com-
petent electrician. Contact your Sears salesperson to
arrange for a professionalelectrician,
Wiring Diagrams (See Wiring Diagrams Section) have been
supplied showing the two most common types of connec-
tions between the water heater and the power supply, You can
easily see which type connection you have by removing the
junction box cover on top of the water heater,
A. Two W'tre Connection Diagrams: is the most common
requiring you to simply connect red to red, black ro black,
and the ground wire to the green ground screw in r_hejunc-
tion box of the water heater_
B. Three Wire Connection Diagram: is used when you are
connecting the water heater to power a supply that has a
_Time Clock" or "Off Peak" Meter. To malce these connec-
tions refer to block I or 2 in this wiring diagram for the type
of system you have.
NOTE: If you have purchased a three wire connection
water heater but you are not on a "Time Clock" or "Off
Pea.k" meter and have a standard two wire connection
lower supply, simply follow the connection diagram in
lock .3 of the Three Wire Connection Diagram_
t Provide a way to easily shut off the electric power when work-
ing on the water hearer_ This could be with a circuit breaker
or fuse block in the entrance box or a separate disconnect
switch
2, Install and connect a circuit directly from the main fuse or
circuit breal_er box,. This circuit must be the right size and
have its own fuse or circuit breaker,. Refer to the chart in the
"Product Specifications" section for the correct size wire and
fuse or circuit breaker_
6_
7,
Use wire nuts and connect the power supply wiring to the
wires inside the water heaters junct'on
The water heater must be electrically "grounded" by the
installer, A green ground screw has been provided on the
water heater's junction box° Connect ground wire to this
location,
8. Replace the wiring junction cover using the screw provided.
3. If'metal conduit is used for the grounding conductor:
A. The grounding electrode conductor shall be of copper,
aluminum, or copperclad aluminum. The material shall
be of one continuous length without a splice or joint.
B. Rigid metal conduit, intermediate metal Conduit, or elec-
trical metallic tubing may be used for the grounding
means if conduit or tubing is terminated in fittings
approved for grounding,
