WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY:
This water heater is equipped for one type voltage only.
Check the rating plate near the bottom access panel 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 questions or doubts
consult your electric company.
If wiring from your fuse box or circuit breaker box was
aluminum for your old water heater, replace it with copper
wire. If you wish to reuse the existing aluminum wire, have
the connection at the water heater made by a competent
electrician. Contact your Sears salesperson to arrange for
a professional electrician.
1. Provide a way to easily shut off the electric power when
working 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 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.
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
electrical metallic tubing may be used for the grounding
means if conduit or tubing is terminated in fittings
approved for grounding.
C. Flexible metal conduit or flexible metallic tubing shall
be permitted for grounding if all the following conditions
are met:
• The length in any ground return path does not
exceed 6 feet.
• The circuit conductors contained therein are protected
by overcurrent devices rated at 20 amperes or less.
• 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 NEC - National Electrical
Code NFPA 70.
4. A standard 1/2” conduit opening has been made in the
water heater junction box for the conduit connection.
5. Use wire nuts and connect the power supply wiring to the
wires inside the water heater’s junction box.
6. 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.
7. Replace the wiring junction cover using the screw provided.
