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 disconnects).
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
Figure 23 on page 17) and ensure that
the home’s voltage, wiring size (ampac-
ity) 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 correct 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).

Connecting the electrical wires.
If metal conduit is used for the grounding
conductor:
•
The grounding electrode conductor
shall be of copper, aluminum, or
copperclad aluminum. The material
shall be of one con nuous length
without a splice or joint.
•
Rigid metal conduit, intermediate
metal conduit, or electrical metallic
tubing may be used for the ground-
ing 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.

The water heater’s electrical re-
quirements 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.
