TEMPERATURE CONTROLS
The front panel temperature control allows the customer to set the hot water supply temperature and will
display certain fault functions of the water heater if there is a malfunction. Residential models can also
have the option of up to two remote temperature controls located near bathroom fixtures for convenient
control of bath and shower temperatures.
Residential Models:
The Main Control is integrally mounted to project through the front panel of the water heater. The
adjustment range for all residential model water heater controls is 98-160
°
F.
DANGER
Hotter water increases the risk of scald injury. Scalding may occur within 5 seconds at a temperature
setting of 140
°
F (60
°
C). To protect against hot water injury, install a mixing valve in the water system.
This valve will reduce point of discharge temperature by mixing cold and hot water in branch water lines.
A licensed plumbing professional or local plumbing authority should be consulted.
CAUTION
This water heater, when set at a lower temperature setting is not capable of producing hot water of
sufficient temperature for sanitizing purposes.
Always check water temperature by hand before entering the shower or bath. The temperature may have
been changed.
Test the temperature of the water with your hand or elbow before placing a child in the bath or shower.
Do not leave a child or an infirm person in the bath unsupervised.
NOTICE
This water heater is equipped with an energy cut out device to prevent overheating. Should overheating
occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance and call a
qualified service agency.
NOTICE
The lower the temperature setting, the greater the energy efficiency to heat the water. Lower water
temperatures also extend the heat exchanger 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 the requirements for the installation.
In addition, all models may have up to two optional additional controls (P/N 239-44509-00) installed in
bathrooms or other remote locations to control the temperature for showers and sinks. When these
controls are used, depressing the Priority Button will override the Main Control and display the setpoint of
the Remote Control in use. Both the Remote Controls and the front panel Main Control will display fault
codes in the event the water heater needs service.
NOTICE
No more than three temperature controls may be connected to the Everhot water heater.
NOTICE
The default temperature setting displayed for residential controls that will appear when the water heater is
first connected to the electrical supply or in the event of a power interruption is 120°F.
