Safety Precautions
DO turn off power to water heater if
it has been subjected to over heating,
fire, flood, physical damage.
DO NOT turn on water heater unless
it is filled with water.
DO NOT turn on water heater if cold
water supply shut-off valve is closed.
If there is any difficulty in
understanding or following the
Operating Instructions or the
Care and Cleaning section, it is
recommended that a qualified person
or serviceman perform the work.
The unit must be completely filled
with water before turning on the
power.
Operating the water heater.
Safety Controls
The water heater is equipped with a
combination thermostat and temperature
limiting control (ECO) that is located
above the heating element in the upper
control box. If for any reason the water
temperature becomes excessively high, the
temperature limiting control (ECO) breaks
the power circuit to the heating element.
Once the control opens, it must be reset
manually.
CAUTION: The cause of the high
temperature condition must be investigated
by qualified service technician and
corrective action must be taken before
placing the water heater in service again.
To reset the temperature limiting control:
Turn off the power to the water
heater.
Remove the jacket access panel(s)
and insulation from the top control
box.
The thermostat protective cover
should not be removed.
Press the red RESET button.
Replace the insulation and jacket
access panel(s) before turning on the
power to the water heater.
WARNING: If the water
heater has been subjected to
flood, fire, or physical damage,
turn off power and water to
the water heater.
DO NOT operate the water
heater again until it has
been thoroughly checked by
qualified service personnel.
!
DANGER: There is a hot
water scald potential if the
thermostat is set too high.
Households with small
children, disabled, or elderly
persons may require a 120°F
(49°C) or lower thermostat
setting to prevent contact with
HOT water.
Water Temperature Setting
The temperature of the water in the water
heater can be regulated by setting the
temperature dial of the adjustable surface
mounted thermostat(s) located behind the
jacket access panel(s).
Dual element heaters have two thermostats.
Safety and energy conservation are factors
to be considered when selecting the water
temperature setting of the water heater’s
thermostat(s). The lower the temperature
setting, the greater the savings in energy and
operating costs.
However, for the best first hour hot water
delivery, the following thermostat settings are
recommended:
Upper Thermostat: 125° F - 130° F
Lower Thermostat: 120° F
To comply with industry standards the
thermostat(s) are factory set at 120°F or less
where local codes require. Canadian models
are set to 140° F (60° C). These are the
recommended starting points.
Contact (such as at the water use fixture)
with water temperatures above 125°F
(51°C) can cause severe burns or death from
scalding. Be sure to read and follow the
warnings outlined in this manual and on the
label on the water heater. This label is located
on the water heater near the thermostat
access panel.
Mixing valves are recommended for
reducing point of use water temperature by
mixing hot and cold water in branch water
lines. It is recommended that a mixing
valve complying with the Standard for
Temperature Actuated Mixing Valves for
Hot Water Distribution Systems, ASSE 1017
be installed. See page 3 for more details
and contact a licensed plumber or the local
plumbing authority for further information.
The chart on the next page may be used
as a guide in determining the proper water
temperature for your home.
!
DANGER: The water
heater will experience the
highest water temperatures the
first time the unit is operated
as it is conditioned and the
temperature stabilizes.
NOTICE: It is important
that the fiberglass insulation
is replaced to maintain water
heater's performance.
