INSTALLATION
3
Open a hot water faucet and
allow the water to run un l it
fl 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 aerator.
6
Check inlet and outlet connec-
 ons 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 connec-
 ons and are not a tank leak.
Step 11:
Make electrical
connec ons
WARNING! Working on an ener-
gized 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 com-
pletely full of water. Although this water
heater is equipped with “Dry Fire” pro-
tec on, be certain all air is purged from
the tank before making any electrical
connec ons.
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.
3
This water heater requires a
240/208 VAC single phase 30
amp power supply, at 60Hz.
Check the water heater’s data plate
(see fi gure 23 on page 15) and ensure
that the home’s voltage, wiring size
(ampacity) and circuit breaker ra ng
and type are correct for this water
heater. Refer to the wiring diagram
located on the water heater for the cor-
rect electrical connec ons. Ensure that
wire sizes, type, and connec ons
comply with all applicable local codes.
In the absence of local codes, follow
NFPA-70 and the current edi on of the
Na onal Electric Code (NEC).

If metal conduit is used for the ground-
ing conductor:
• The grounding electrode conduc-
tor shall be of copper, aluminum,
or copperclad aluminum. The ma-
terial shall be of one con nuous
length without a splice or joint.
• Rigid metal conduit, intermedi-
ate metal conduit, or electrical
metallic tubing may be used for
the grounding means if conduit
or tubing is terminated in fi  ngs
approved for grounding.
• Flexible metal conduit or fl exible
metallic tubing shall be permi ed
for grounding if all the following
condi ons are met:
A. The length in any ground return
path does not exceed 6 feet.
B. The circuit conductors contained
therein are protected by overcurrent
devices rated at 30 amperes.
C. The conduit or tubing is terminated
in fi  ngs approved for grounding.
For complete grounding details and
all allowable excep ons, refer to the
current edi on of the Na onal Electric
Code NFPA 70.
Figure 23 - The water heater’s electrical
requirements can be determined from the
data plate.
4
Remove the cover on the
electrical junc on 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 nuts or
other approved means to make the
power connec ons.
7
Replace the junc on box
cover and secure with the
screw provided.
WARNING! Be sure cover is secured
to reduce the risk of fi re and electric
shock.
