ment. the tank must be filled w_th water. Water must
flow from the hot water faucet before turning on power.
You must provide all wiring of the proper size outside of the
water heater. You must obey local codes and electric company
requirements when you install this wiring.
If you are not familiar with electric codes and practices, or if you
have any doubt, even the slightest doubt, in your ability to con-
nect the wiring to this water heater, obtain the service of a com-
petent electrician. Contact your Sears salesperson to arrange for
a professional electrician.
C. Flexible metal conduit or flexible metallic tubing shall be
permitted for grounding if all the following conditions are
met:
1. The length in any ground return path does not exceed
6 feet.
2. The circuit conductors
contained
therein are _rotected
by overcurrent
devices rated at 20 amperes or Jess.
3. The
conduit
or tubing
is terminated
in fittings
approved for grounding.
For complete grounding details and all allowable exceptions,
refer to the latest edition of the National Electrical Code.
4. A standard ½" conduit opening has been made in the water
heater junction box for the conduit connection.
AWARNING
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 shown on the model
rating plate. Failure to use the correct voltage can cause
problems which can result in DEATH. SERIOUS BODILY
INJURY,OR PROPERTY DAMAGE. If you have any ques-
tions or doubts consult your electric company.
ACAUTION
If wiring from your fuse box or circuit breaker box was
aluminum for your old water heater, replace it with cop-
per wire. If you wish to reuse the existing aluminum wire,
havethe 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 Ware Connection
Diagrams:
is the most common
requiring
you to simply connect
red to red, black to black,
and the ground wire to the green ground
screw in the junc-
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 make these connec-
tions refer to block 1 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
Peak" meter and have a standard
two wire connection
lower supply, simply follow the connection diagram in
lock 3. of the Three Wire Connection
Diagram.
1. Provide a way to easily shut off the electric power when work-
ing on the water heater. 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
breaker box. This circuit must be the right size and
have irs 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 heater's junction.
The water heater must be electrically "grounded"
by the
installer. A _reen 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.
