Installation Guide

Electric Mini Tank Water Heater • 5
According to a na onal standard:
American Society of Sanitary Engineering
(ASSE 1070) and most local plumbing codes,
the water heater’s thermostat should not
be used as the sole means to regulate water
temperature and avoid scalds.
Properly adjusted Thermosta c Mixing
Valves installed at each point-of-use allow
you to set the tank temperature to a higher
se ng without increasing risk of scalds.
Higher tank temperatures (140°F) also kill
bacteria that cause a condi on known as
“smelly water” and can reduce the levels of
bacteria that cause water-borne diseases.
Water Contamination Risk
Do not use chemicals that could contami-
nate the potable water supply. Do not use
piping that has been treated with chro-
mates, boiler seal, or other chemicals.
Fire Risk
To reduce the risk of a fire
that could destroy your
home and seriously injure
or kill people:
• D o not store things that can burn easily
such as paper or clothes next to the
water heater.
• Be sure the junction box cover and the
access door covers are in place. These
covers keep debris from entering and
potentially being ignited, and help keep
any internal fires from spreading.
• Keep the water heater from becoming
wet. Immediately shut the water heater
off and have it inspected by a quali-
fied person if you find that the wiring,
thermostat(s) or surrounding insulation
have been exposed to water in any way
(e.g., leaks from plumbing, leaks from
the water heater itself can damage
property and could cause a fire risk). If
the water heater is subjected to flood
conditions or the thermostat(s) have
been submerged in water, the entire
water heater must be replaced.
• For 6 gallon models, make electrical
connections properly, according to the
instructions on page 14. Use suit-
able twist on wire connectors or other
approved means to make the power
connections. Use a UL listed or CSA
approved strain relief. Connect ground
wire to ground screw.
Explosion Risk
High temperatures and
pressures in the water heater
tank can cause an explosion
resulting in property damage, serious
injury or death. A new Temperature and
Pressure (T&P) Relief Valve is included
with your water heater to reduce risk of
explosion by discharging hot water.
Additional temperature and pressure
protective equipment may be required by
local codes.
A nationally recognized testing laborato-
ry maintains periodic inspection of the
valve production process and certifies
that it meets the requirements for Relief
Valves for Hot Water Supply Systems,
ANSI Z21.22. The T&P Relief Valve’s relief
pressure must not exceed the working
pressure rating of the water heater as
stated on the rating plate.
Maintain the T&P Relief Valve properly.
Follow the maintenance instructions
provided by the manufacturer of the T&P
Relief Valve (label attached to T&P Relief
Valve) and the procedure that starts on
page 21.
An explosion could occur if the T&P Relief
Valve or discharge pipe is blocked. Do not
cap or plug the T&P Relief Valve or dis-
charge pipe.
Fire and Explosion Risk if Hot Water is Not
Used for Two Weeks or More
C AUTION! Hydrogen gas builds up in
a hot water system when it is not used
for a long period (two weeks or more).
Hydrogen gas is extremely fl ammable. If
the hot water system has not been used
for two weeks or more, open a hot water
faucet for several minutes at the kitchen
sink before using any electrical appliances
connected to the hot water system. Do
not smoke or have an open fl ame or other
igni on source near the faucet while it is
open.
