Residenal Electric Water Heater Use and Care Guide • 17
INSTALLATION
INSTALLATION
3
Open a hot water faucet and
allow the water to run unl it
ows with a full stream.
4
Let the water run full stream
for three full minutes.
5
Close the hot water faucet
and replace the ow restrictor.
6
Check inlet and outlet
connecons and water pipes
for leaks. Dry all pipes so that
any drips or leaks will be apparent.
Repair any leaks. Almost all leaks occur
at connecons and are not a tank leak.
Step 14:
Make Electrical
Connecons
WARNING! Working on an
energized circuit can result in severe
injury or death from electrical shock.
NOTICE: Do not turn electrical power
on unless you are sure all of the air
is out of the tank and the tank is
completely full of water. Although this
water heater is equipped with “Dry-
Fire” protecon, be certain all air is
purged from the tank before making
any electrical connecons.
1
Be sure the electrical power
to the water heater is turned
OFF at the circuit breaker
panel (or remove the circuit’s fuses).
2
Using a non-contact circuit
tester, check the wiring to
make certain the power is OFF
and the circuit is not energized.
3
This water heater requires a
208/240 VAC single phase 30
amp power supply, at 50Hz or
60Hz. Check the water heater’s data
plate (Figure 22) and ensure that the
home’s voltage, wiring size (ampacity)
and circuit breaker rang and type are
correct for this water heater. Refer to
the wiring diagram located on the
water heater, and on page 38 of this
manual, for the correct electrical
connecons. Ensure that wire sizes,
type, and connecons comply with all
applicable local codes. In the absence
of local codes, follow NFPA-70 and the
current edion of the Naonal Electric
Code (NEC).

Figure 21 - Connecting the electrical wires
(bottom cover to electrical junction box removed
for clarity).
If metal conduit is used for the
grounding conductor:
• The grounding electrode conductor
shall be 10 gauge solid copper wire.
The copper wire shall be of one
connuous length without a splice
or joint.
• Rigid metal conduit, intermediate
metal conduit, or electrical metallic
tubing may be used for the
grounding means if conduit or tubing
is terminated in ngs approved for
grounding.
• Flexible metal conduit or exible
metallic tubing shall be permied
for grounding if all the following
condions are met:
I. The length in any ground return
path does not exceed 6 feet/1.8 m.
II. The circuit conductors contained
therein are protected by
overcurrent devices rated at 30
amperes.
III. The conduit or tubing is terminated
in ngs approved for grounding.
For complete grounding details and
all allowable excepons, refer to the
current edion of the Naonal Electric
Code NFPA-70.
Figure 22 - The water heater’s electrical
requirements can be determined from the data
plate.
4
Remove the top and boom
covers on the electrical
juncon box on the side of
the water heater.
5
Install wiring in an approved
conduit (if required by local
codes). Use a UL listed or CSA
approved strain relief to secure the
electrical wiring to the water heater.
6
Connect the ground wire to
the green ground screw.
Connect the home’s two
power wires to the water heater’s two
power wires. Use suitable wire
connectors or other approved means
to make the power connecons.
7
Replace the juncon box
covers and secure with the
screws provided.
WARNING! Be sure cover is secured
to reduce the risk of re and electric
shock.
