Bradford-White Corp TGHE-160I-N(X) Turning OFF the Water Heater for AN Extended Period of Time

Page 58

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 Figure 39).

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 fails to shut off, turn off the manual gas control valve to the water heater and call a qualified service agent.

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.

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 (or optional remote controls). 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.
