Temperature Adjustment
The temperature selector knob of the thermostat has been adjusted to its
lowest setting when shipped from the factory.
The detent on the thermostat temperature scale (shown below) is the
preferred starting point for setting the temperature control. For energy-
efficient operation of your water heater, the suggested initial temperature
setting is approximately 130°F (55°C). Households with small children or
invalids may require a 120°F (49°C) or lower temperature setting to reduce
the risk of scald injury. Some states require a lower temperature setting. Full

counterclockwise
rotation of the temperature selector knob is the
minimum temperature setting. Full clockwise
rotation of the
temperature selector knob is the maximum temperature setting. NOTE: The
lower the temperature setting, the greater the energy efficiency, both to heat
the water and to maintain its temperature during standby periods. Lower
water temperatures also extend tank life. Remember, no water heating
system will provide exact temperatures at all times. Allow a few days of
operation at this setting to determine the correct temperature setting
consistent with your needs. NOTE: This water heater, when set at a lower
temperature setting, is not capable of producing hot water of sufficient
temperature for sanitizing purposes.
During winter season or any cold period, you may desire a higher temperature
setting to adjust for the colder incoming water. This adjustment, however,
may cause additional condensation to form on the cooler tank surface. This
does not mean the tank is leaking. During summer months, the warmer
incoming water temperatures will benefit the performance of your water heater
and reduce the amount of condensation developed.
Condensation does not mean your tank is leaking. Over 40% of reported tank
leaks on installation are proven to be condensation. To avoid unnecessary
expense and inconvenience, make sure the tank is leaking before calling a
service person.
