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
completely full of water. If power is
applied before the tank is completely
full of water, the upper element will
burn out (Dry Fire).
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
Check the water heater’s
data plate 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 correct electrical connec ons.
Ensure that wire sizes, type, and
connec ons comply with all appli-
cable local codes. In the absence of
local codes, follow NFPA-70 and the
current edi on of the Na onal Electric
Code (NEC).
4
Remove the cover on the
electrical junc on box on the
top 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
four power wires (black to black, red
to red). Use suitable wire nuts or
other approved means to make the
power connec ons.
NOTICE: The tank must be com-
pletely empty of air and full of
water before connec ng electrical
power to avoid “Dry Firing.” Dry
Firing may result in the upper ele-
ment burning out. This is a com-
mon installa on mistake. A er
you make the water connec ons,
but before you connect the electri-
cal power, open a hot water faucet
and let the water run full un l all
the air is removed. Let the “hot”
water run full for three minutes
or longer before connec ng any
electrical wires. A Dry Fired upper
hea ng element is an installa on
error and is not covered under
warranty.
If Dry Firing occurs, replace the up-
per hea ng element according to
the instruc ons on page 30.
Step 9:
The water heater’s electrical requirements can
be determined from the data plate.
