The chart shown above may be used as a guide in determining the proper water temperature for your home.
Water Heater Temperature Setpoint
The water heater temperature setting strongly impacts the amount of usable hot water available for showers
and baths.
•
Energy consumption/savings and efficiency testing of water heaters is performed according to the
Department of Energy (DOE) requirements specified at the date of manufacture.
•
Safety regulations require a factory setting of 120°F to 125°F (49°C to 52°C) maximum for all new
water heaters. Therefore, if the water heater is currently set at 130°F (54°C) or above and the new
water heater is installed with a factory set setpoint of 120°F (49°C), the new water heater may seem to
provide lower capacity than the existing water heater.
•
The user can adjust the temperature setting to meet their needs.
•
Always read and understand the safety instructions contained in the Installation and Operation Manual
before adjusting the temperature setpoint.

Check the markings on the rating plate of the water heater to be certain the power supply corresponds to
the water heater requirements.

208V installations may experience lower recovery performance.
Locating the Water Heater
WARNING
Water heaters are heat producing appliances. To avoid damage or injury, there shall be no material stored
against the water heater and proper care shall be taken to avoid unnecessary contact (especially by
children) with the water heater.
UNDER NO CIRCUMSTANCES SHOULD FLAMMABLE MATERIALS, SUCH AS GASOLINE OR
PAINT THINNER BE USED OR STORED IN THE VICINITY OF THIS WATER HEATER OR ANY
LOCATION FROM WHICH FUMES COULD REACH THE WATER HEATER.
This water heater MUST be installed indoors out of the wind and weather.
The water heater should NOT be located in an area where leakage of the tank or connections will
result in damage to the area adjacent to it or to lower floors of the structure. Where such areas
cannot be avoided, it is recommended that a suitable catch pan, adequately drained, be installed
under the water heater.
