CAUTION
In climates where below freezing temperatures may occur, the water heater must be drained when
power is off to the water heater to prevent freeze damage to the heat exchanger. Drain solenoids are
recommended to prevent freeze damage during power failures in cold climate regions.
TURNING OFF THE WATER HEATER FOR AN EXTENDED PERIOD OF TIME
If the EVERHOT
® water heater is to be turned off for an extended period of time, the following steps
should be taken.
1. Turn the gas shutoff valve on the gas supply inlet to the OFF position (see operating
instructions).
2. Disconnect the electrical supply to the water heater.
3. Shut off the cold water supply to the water heater and open the drain valve to drain the water
heater. If the water heater was installed with drain solenoid freeze protection, the water heater
will drain automatically when power is disconnected.
TEMPERATURE ADJUSTMENT
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.
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.
Residential Models (See figure 48):
1. The outlet water temperature of the EVERHOT
® water heaters is adjusted using the Main Control
located on the front panel of the water heater. When a remote temperature control is installed,
the temperature can only be adjusted on the control that has the Priority Indicator Light glowing.
The temperature displayed on the control in use will also be displayed on all the other remote
controls.
