WARNING

Do not adjust this water heater in any residential application above 120ºF. If this water heater is used in a commercial application where temperatures in excess of 120ºF are required, use an ASSE approved mixing device.

WARNING

This water heater is equipped with an energy cut out device to prevent overheating. Should overheating occur or the gas supply fails to shut off, turn off the manual gas control valve to the water heater, 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.

When multiple 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 main control will display diagnostic codes in the event the water heater needs service.

NOTICE

No more than four temperature controls may be connected to the EverHot® water heater.

NOTICE

The default temperature setting that will appear when the water heater is first connected to the electrical supply is 104ºF. In the event of a power interruption, the unit will retain its set temperature for up to 6 hours. If the power is interrupted for more than 6 hours, the unit will revert back to a temperature of 104°F.

Before installing optional remote controls, determine the most convenient locations(s). When deciding on the best location for the remote controls, please consider the following items:

1.Place the controls out of reach of small children.

2.Avoid locations where the control(s) will become hot, such as over a radiator, register, or other heat sources.

3.Avoid direct sunlight. The digital readout can be difficult to read in direct sunlight.

4.Avoid areas where the remote can be splashed with cooking water, oil, or sauce.

5.The remote control operates with low voltage.
