51CAUTIONIn climates where below freezing temperatures may occur, the water heater must be drained whenpower is off to the water heater to prevent freeze damage to the heat exchanger. Drain solenoids arerecommended to prevent freeze damage during power failures in cold climate regions.TURNING OFF THE WATER HEATER FOR AN EXTENDED PERIOD OF TIMEIf the EVERHOT® water heater is to be turned off for an extended period of time, the following stepsshould be taken.1. Turn the gas shutoff valve on the gas supply inlet to the OFF position (see operatinginstructions).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 waterheater. If the water heater was installed with drain solenoid freeze protection, the water heaterwill drain automatically when power is disconnected.TEMPERATURE ADJUSTMENTDANGERHotter water increases the risk of scald injury. Scalding may occur within 5 seconds at a temperaturesetting 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 waterlines. A licensed plumbing professional or local plumbing authority should be consulted.CAUTIONThis water heater, when set at a lower temperature setting is not capable of producing hot water ofsufficient temperature for sanitizing purposes.Always check water temperature by hand before entering the shower or bath. The temperature mayhave been changed.NOTICEThis water heater is equipped with an energy cut out device to prevent overheating. Shouldoverheating occur or the gas supply fail to shut off, turn off the manual gas control valve to theappliance and call a qualified service agency.NOTICEThe lower the temperature setting, the greater the energy efficiency to heat the water. Lower watertemperatures also extend the heat exchanger life. Remember, no water heating system will provideexact temperatures at all times. Allow a few days of operation at this setting to determine the correcttemperature 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 Controllocated 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 remotecontrols.
