STEPS TO INSTALL YOUR
If the factory setting is satisfactory for your needs, replace the
front panel and turn on the electric supply to the water heater.
CAUTION: BE SURE THE WATER HEATERIS COMPLETELY
FULL OF WATER BEFORE TURNING ON THE ELECTRICITY
(SEE STEP 7 ON PAGE&) Be sure the cold water supply to
the water heater is fully on.
If you want to set the water heater to a higher temperature,
DO NOT TURN ON THE ELECTRIC POWER. FIRST READ
THE TEMPERATURE CONTROLS SECTION AND ALL
WARNINGS.
WARNING
WATER TEMPERATURE OVER 125 DEGREES
FAHRENHEIT CAN CAUSE BURNS OR DEATH FROM
SCALDS. CHILDREN, DISABLED AND ELDERLY ARE
AT HIGHER RISK OF BEING SCALDED. ALWAYS FEEL
WATER BEFORE BATHING OR SHOWERING.
TEMPERATURE LIMITING VALVESWITH INSTRUCTIONS
ARE AVAILABLE FROM PLUMBING SUPPLY AND
HARDWARE STORES.
THERMAL EXPANSION
Water supply systems may, because of high line pressure,
frequent cut-offs, the effects of water hammer and others,
have installed devices such as pressure-reducing valves,
check valves, back flow preventors, etc.., to control these
types of problems. When these devices are not equipped with
an internal by-pass, and no other measures are taken, the
devices cause the water system to be closed. As water is
heated, it expands (thermal expansion) and closed systems
do not allow for the expansion of heated water.
The water within the water heater tank expands as it is heated
and increases the pressure of the water system. If the relieving
point of the water heater's temperature and pressure relief
valve is reached, the temperature and pressure relief valve will
relieve the excess pressure. The temperature and pressure
relief valve is not intended for the constant relief of thermal
expansion. This is an unacceptable condition and must be
corrected. Do not plug the temperature and pressure relief
valve.
If the system has any devices installed which could create a
closed system, install a by-pass and/or an expansion tank to
relieve the pressure built by thermal expansion in the water
system. Expansion tanks are available for ordering through
the Sears Service Center. Contact the local water supplier
and/or Sears Service Center for assistance in controlling these
situations.
TEMPERATURE AND PRESSURE
RELIEF VALVE
The relief valve, located on top of the water heater, protects
against dangerously excessive temperature and/or pressure
buildup insidethe water heater. The relief valve automatically
opens, if temperature or pressure gets too high, to relieve
hot water and/or pressure to the drain. SEE VALVE
REQUIREMENTS ON PAGE 4, AND YEARLY CARE FOR
THE VALVEON PAGE 10 AND 11.

TEMPERATURE CONTROLS
The upper,and lower heating elements have the same kind of
temperature control thermostats. MODEL NUMBER
449.314410 HAS ONLY A LOWER HEATING ELEMENTAND
CONTROL THERMOSTAT.The thermostat(s) are factory set to
keep the water at approximately 120 degrees Fahrenheit. At
120 degrees Fahrenheit, water is hot enough for most
household needs.
Safety and energy conservation are factors to be considered
when selecting the water temperature setting of water heater's
thermostat. Water temperatures above 120° E can cause
severe burns or death from scalding. Be sure to read and
follow the warnings outlined below.
Maximum water temperatures occur just after the elements
have shut off. To find hot water temperature being delivered,
turn on a hot water faucet and place a thermometer in the hot
water stream and read the thermometer.
The following chart may be used as a guide in determining the
proper water temperature for your home.
