Instruction Manual RESIDENTIAL ELECTRIC WATER HEATERS FOR POTABLE WATER HEATING ONLY NOT SUITABLE FOR SPACE HEATING LISTED GAMA certification applies to all residential electric water heaters with capacities of 20 to 120 gallons. Input rating of 12 Kw or less. ALL TECHNICAL AND WARRANTY QUESTIONS: SHOULD BE DIRECTED TO THE LOCAL DEALER FROM WHOM THE WATER HEATER WAS PURCHASED. IF YOU ARE UNSUCCESSFUL, PLEASE WRITE TO THE COMPANY LISTED ON THE RATING PLATE ON THE WATER HEATER.
SAFE INSTALLATION, USE AND SERVICE Your safety and the safety of others is extremely important in the installation, use and servicing of this water heater. Many safety-related messages and instructions have been provided in this manual and on your own water heater to warn you and others of a potential injury hazard. Read and obey all safety messages and instructions throughout this manual.
GENERAL SAFETY 3
INTRODUCTION Thank You for purchasing this water heater. Properly installed and maintained, it should give you years of trouble free service. 2. The installation must conform with these instructions and the local code authority having jurisdiction and the requirements of the power company. In the absence of code requirements follow NFPA-70 (latest edition). The National Electric Code which may be ordered from: National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269.

TYPICAL INSTALLATION LOWBOYS UPRIGHTS COMPACTS TABLE TOPS 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. INSTALL THERMAL EXPANSION TANK OR DEVICE IF WATER HEATER IS INSTALLED IN A CLOSED WATER SYSTEM. FIGURE 1.
MIXING VALVE USAGE FIGURE 2. Water (Potable) Heating: All models are considered suitable for water (potable) heating only. 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. Some people are more likely to be permanently injured by hot water than others.
LOCATING THE NEW WATER HEATER damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are available from your local plumbing contractor. Such a drain pan must have a minimum length and width of at least 2 inches (51 mm) greater that the water heater dimensions and must be piped to an adequate drain.
TEMPERATURE-PRESSURE RELIEF VALVE 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. This is an unacceptable condition and must be corrected.
The Discharge Pipe: 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. • 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.
WIRING DIAGRAMS TURN OFF THE HEATER ELECTRICAL SUPPLY BEFORE SERVICING ANY ELECTRICAL COMPONENTS. FIGURE 6.
WIRING 1. Provide a way to easily shut off the electric power when working on the water heater. This could be with a circuit breaker or fuse block in the entrance box or a separate disconnect switch. 2. Install and connect a circuit directly from the main fuse or circuit breaker box. This circuit must be the right size and have its own fuse or circuit breaker. 3. If metal conduit is used for the grounding conductor: Never use water heater unless it is completely full of water.
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. TEMPERATURE ADJUSTMENT Any water heater’s intended purpose is to heat water. Hot water is needed for cleansing, cleaning, and sanitizing (bodies, dishes, clothing). Untempered hot water can present a scald hazard.
FOR Y OUR INFORMA TION YOUR INFORMATION THERMAL EXPANSION “AIR” IN HOT WATER FAUCETS 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.
PERIODIC MAINTENANCE ANODE ROD INSPECTION 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. If the temperature-pressure relief valve on the appliance weeps or discharges periodically, this may be due to thermal expansion.
1. Turn “OFF” the electric power supply to the water heater. 4. Remove the two wires attached to the thermostat. 2. Remove the outer door, insulation block and pad in the order they are installed. 5. Remove the thermostat from behind the thermostat bracket. 3. A. 6. Disconnect wires from thermostat and slide out of the bracket. Models with lower thermostat without high limit: Lift out the tab as shown below to unclip the terminal cover from the thermostat.
The water passing out of the drain valve may be extremely hot. To avoid being scald, make sure all connections are tight and that the water flow is directed away from any person. B. 4. Remove the two screws securing the outer door, and remove door. Models with Upper or Lower Thermostat with High Limit: Lift out the tab as shown below to unclip the terminal cover from the thermostat. The terminal cover can now be removed from the thermostat. FIGURE 14. 5. Remove the insulation block and pad. FIGURE 17.
11. 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. 12.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. 13.To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping. FIGURE 21.
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. *B. The anode rod fitting may be leaking. C. Small amounts of water from temperature-pressure relief valve may be due to thermal expansion or high water pressure in your area.
TROUBLESHOOTING GUIDELINES These guidelines should be utilized by a qualified service agent. Problem Cause WATER LEAKS (See Leakage Checkpoints on 19) Improperly sealed, hot or cold supply connection, relief valve or drain valve. Tighten threaded connections. Leakage from other appliances or water lines. Inspect other appliances near water heater. Thermal expansion in closed water system. Install thermal expansion tank (DO NOT plug T&P valve). Improperly seated valve.
