Electric Mini Tank Water Heater • 13
NOTICE: The tank must be completely
empty of air and full of water before
connec ng electrical power to avoid
“Dry Firing.” Dry Firing may result in
the element burning out. This is a
common installa on mistake. A er
you make the water connec ons,
but before you connect the electrical
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 hea ng element is an installa-
 on error and is not covered under
warranty.
If Dry Firing occurs, replace the heat-
ing element according to the instruc-
 ons on page 20.
Step 8: (6 Gal. Models)
Make electrical
connec ons (2.5 and 4
gallon models have a
power cord, plug into an
outlet)
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. If power is applied before the tank
is completely full of water, the 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 inside of water
heater’s bo om compartment 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).
4
Remove the cover on the electri-
cal junc on box on the back of the
water heater.
Figure 17 - The water heater’s electrical require-
ments can be determined from the data plate.
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
ensure that the green ground wire
is connected to the ground screw.
Connect yellow and green ground
wire to the supply ground wire. Connect
the supply line and supply neutral to the
water heater line (black wire) and neutral
(white wire). Use suitable wire connectors
or other approved means to make the
power connec ons.

WARNING! Be sure cover is secured to
reduce the risk of fi re and electric shock.
