8 FACTS TO CONSIDER ABOUT THE LOCA TION Carefully choose an indoor location for the new water heater , because the placement is a very important consideration for the safety of the occupants in the building and for the most economical use of the appliance.
9 The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of the water heater’s temperature-pressure relief valve is reached, the valve will relieve the excess pressure. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion.
10 The Discharge Pipe: • Shall not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions. • Shall not be plugged or blocked.
11 KEEPING THE THERMOST A T SETTING A T 120°F WILL REDUCE THE RISK OF SCALDS. Figure 7 shows the approximate time-to-burn relationship for normal adult skin. The thermostats on your water heater have a linear relationship between degrees of angular rotation and the corresponding change in temperature.
12 THERMAL EXP ANSION W ater supply systems may , because of such events as high line pressure, frequent cut-offs, the effects of water hammer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, etc.
13 The water heater should be drained if being shut down during freezing temperatures. Also periodic draining and cleaning of sediment from the tank may be necessary . 1 . Turn electrical supply “OFF”. 2 . CLOSE the cold water inlet valve to the water heater .
14 LEAKAGE CHECKPOINTS Read this manual first. Then before checking the water heater make sure the electrical power supply has been turned “OFF” before checking the tank for leakage. *A. Condensation and dripping may be seen on pipes if the water temperature is low in humid weather or pipe connections may be leaking.
