Residen  al Electric Water Heater Use and Care Guide • 5

requiring a certain water temperature 
at the hot water tap, then these precau-

 ons are par  cularly important. 

According to a na  onal standard 
American Society of San  ary Engineer-
ing (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 al-
low you to set the tank temperature to 
a higher se   ng without increasing risk 
of scalds. A higher temperature se   ng 
allows the tank to provide much more 
hot water and can help provide proper 
water temperatures for appliances such 
as dishwashers and washing machines. 
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 Contamina  on Risk
Do not use chemicals that could con-
taminate the potable water supply. Do 
not use piping that has been treated 
with chromates, boiler seal, or other 
chemicals.

Fire Risk 
To reduce the risk of a 
fi re that could destroy 
your home and seriously 

injure or kill people:

•  Do not store things that can burn 

easily such as paper or clothes next to 
the water heater.

•  Be sure the junc  on box cover and 

the access door covers are in place. 
These covers keep debris from enter-
ing and poten  ally being ignited, 

and help keep any internal fi res from 
spreading.

•  Keep the water heater from becom-

ing wet. Immediately shut the water 
heater off  and have it inspected by a 
qualifi ed person if you fi nd that the 
wiring, thermostat(s) or surrounding 
insula  on have been exposed to wa-
ter in any way (e.g., leaks from plumb-
ing, leaks from the water heater 
itself can damage property and could 
cause a fi re risk). If the water heater 
is subjected to fl ood condi  ons or the 
thermostat(s) have been submerged 
in water, the en  re water heater must 
be replaced.

•  Make electrical connec  ons properly, 

according to the instruc  ons on page 
14.  Use 10 gauge solid copper wire.  
Use a UL listed or CSA approved strain 
relief.  Connect ground wire to green 
ground screw.

Explosion Risk
High temperatures and 
pressures in the water 
heater tank can cause an 

explosion resul  ng in property damage, 
serious injury or death.  A new Tem-
perature and Pressure (T&P) Relief 
Valve is included with your water heater 
to reduce risk of explosion by discharg-
ing hot water. Addi  onal temperature 
and pressure protec  ve equipment may 
be required by local codes.

A na  onally recognized tes  ng labo-
ratory maintains periodic inspec  on 
of the valve produc  on process and 
cer  fi es 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 ra  ng of the wa-
ter heater as stated on the ra  ng plate.

Maintain the T&P Relief Valve properly. 
Follow the maintenance instruc  ons 
provided by the manufacturer of the 
T&P Relief Valve (label a  ached to T&P 
Relief Valve) and the procedure that 
starts on page 24.

An explosion could occur if the T&P Re-
lief Valve or discharge pipe is blocked. 
Do not cap or plug the T&P Relief Valve 
or discharge pipe.
