6 MIXING VAL VE USAGE FIGURE 2. W ater (Pot able) Heating: All models are considered suitable for water (potable) heating only . HOTTER W A TER CAN SCALD: W ater heaters are intended to produce hot water.
7 Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor .
8 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.
9 The valve is certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment of materials as meeting the requirements for Relief V alves and Automatic Gas Shut-off Devices for Hot Water Supply Systems, ANSI Z21.
10 T o fill the water heater with water: 1. Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater . 2. Open the cold water supply valve to the water heater . NOTE: The cold water supply valve must be left open when the water heater is in use.
11 WIRING DIAGRAMS TURN OFF THE HEA TER ELECTRICAL SUPPL Y BEFORE SERVICING ANY ELECTRICAL COMPONENTS. FIGURE 7..
12 WIRING Never use water heater unless it is completely full of water . T o prevent damage to the tank and heating element, the tank must be filled with water . Water must flow from the hot water faucet before turning on power . Y ou must provide all wiring of the proper size outside of the water heater .
13 TEMPERA TURE ADJUSTMENT T o change the temperature setting: NOTE: It is not necessary to adjust the upper thermostat. However , if it is adjusted above the factory set point (120°F (49°C)/HOT) it is recommended that it not be set higher than the lower thermostat setting.
14 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.
15 If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater , follow the draining instructions, and replace the temperature-pressure relief valve with a new one.
16 1 . Turn “OFF” the electric power supply to the water heater . 2 . Remove the outer door , insulation block and pad in the order they are installed. 3. A . Models with lower thermostat without high limit: Lift out the tab as shown below to unclip the terminal cover from the thermostat.
17 The water passing out of the drain valve may be extremely hot. T o avoid scalding, make sure all connections are tight and that the water flow is directed away from any person. 4 . Remove the two screws securing the outer door , and remove door . FIGURE 15.
18 1 1. Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater . 1 2 . Open the cold water supply valve to the water heater . NOTE: The cold water supply valve must be left open when the water heater is in use.
19 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.
20 These guidelines should be utilized by a qualified service agent. TROUBLESHOOTING GUIDELINES Improperly sealed, hot or cold supply connection, relief valve or drain valve. Leakage from other appliances or water lines. Thermal expansion in closed water system.
