  • Page 5: Typical Installation

    TYPICAL INSTALLATION INSTALL SUITABLE DRAIN PANS UNDER HEATERS TO PREVENT DAMAGE DUE TO LEAKAGE. REFER TO WATER HEATER LOCATION ON PAGE 8. INSTALL VACUUM RELIEF IN COLD WATER INLET LINE AS REQUIRED BY LOCAL CODES. FIGURE 1. INSTALL THERMAL EXPANSION TANK OR DEVICE IF WATER HEATER IS INSTALLED IN A CLOSED WATER SYSTEM.

  • Page 6: Mixing Valve Usage

    Water (Potable) Heating: All models are considered suitable for water (potable) heating only. LOCATING THE NEW WATER HEATER FACTS TO CONSIDER ABOUT THE LOCATION MIXING VALVE USAGE FIGURE 2. HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact.

  • Page 7: Locating The New Water Heater

    LOCATING THE NEW WATER HEATER 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.

  • Page 8: Water Piping Pressure Test

    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.

  • Page 9: Temperature-Pressure Relief Valve

    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 Valves and Automatic Gas Shut-off Devices for Hot Water Supply Systems, ANSI Z21.22 • CSA 4.4, and the code requirements of ASME.

    To 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.

    WIRING DIAGRAMS TURN OFF THE HEATER ELECTRICAL SUPPLY BEFORE SERVICING ANY ELECTRICAL COMPONENTS. FIGURE 7.

  • Page 12: Wiring

    Never use water heater unless it is completely full of water. To 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. You must provide all wiring of the proper size outside of the water heater.

  • Page 13: Temperature Regulation

    TEMPERATURE REGULATION Due to the nature of the typical water heater, the water temperature in certain situations may vary up to 30°F (16.7 °C) higher or lower at the point of use such as, bathtubs, showers, sink, etc. Any water heater’s intended purpose is to heat water. Hot water is needed for cleansing, cleaning, and sanitizing (bodies, dishes, clothing).

  • Page 14: For Your Information

    FOR YOUR INFORMATION THERMAL EXPANSION Water 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. to control these types of problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices cause the water system to be closed.

  • Page 15: Periodic Maintenance

    PERIODIC MAINTENANCE ANODE ROD INSPECTION The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod.

  • Page 16: Element Cleaning/Replacement

    Turn “OFF” the electric power supply to the water heater. Remove the outer door, insulation block and pad in the order they are installed. Models with lower thermostat without high limit: Lift out the tab as shown below to unclip the terminal cover from the thermostat.
  • Page 17 The water passing out of the drain valve may be extremely hot. To avoid scalding, make sure all connections are tight and that the water flow is directed away from any person. Remove the two screws securing the outer door, and remove door.

    LEAKAGE CHECKPOINTS FIGURE 24. 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.
