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. This application has been listed as complying with UL Standard for safety UL174. Abbreviations Found In This Instruction Manual: 2. The installation must conform with these instructions and the local code authority having jurisdiction and the requirements of the power company.
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. INSTALL THERMAL EXPANSION TANK OR DEVICE IF WATER HEATER IS INSTALLED IN A CLOSED WATER SYSTEM. FIGURE 1. MIXING VALVE USAGE Water (Potable) Heating: All models are considered suitable for water (potable) heating only. contractor. Consult a Qualified Installer or Service Agency.
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.
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, cleaning 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. These include the elderly, children, the infirm, or physically/mentally handicapped.
If replaced, the valve must meet the requirements of local codes, but not less than a combination temperature and pressure relief valve certified as indicated in the above paragraph. Figure 7 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 3/4 inch NPT water connections.
The temperature-pressure relief valve must be manually operated at least once a year. Caution should be taken to ensure that (1) no one is in front of or around the outlet of the temperature-pressure relief valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot.
WIRING DIAGRAMS TURN OFF THE HEATER ELECTRICAL SUPPLY BEFORE SERVICING ANY ELECTRICAL COMPONENTS. OPTIONAL CORD SET WIRING (120 Volt and 240 Volt) There may be a cord set supplied with the water heater at the time of manufacture. If not one can be ordered through the Parts Department; see “Repair Parts List” section. Refer to Figure 9 for wiring diagrams. 120 VOLT WIRING 120 VOLT WIRING 240 VOLT WIRING FIGURE 9.
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: A. The grounding electrode conductor shall be of copper, aluminum, or copperclad aluminum.
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 YOUR INFORMATION bleach as needed. On systems where the odor is mild and does not occur too rapidly, a monthly flushing may be sufficient. In more severe cases, a system feeder would be more appropriate. 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.
PERIODIC MAINTENANCE TEMPERATURE-PRESSURE RELIEF VALVE OPERATION 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. 3. OPEN a nearby hot water faucet and leave open to allow for draining. 4. Connect a hose to the drain valve and terminate to an adequate drain. 5.
4. Remove the two wires attached to the thermostat. 5. Remove the thermostat from behind the thermostat bracket. 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. 6. Disconnect wires from thermostat and slide out of the bracket. 4. Remove the two screws securing the outer door, and remove door. 7.
8. Clean the area around the element opening. Remove any sediment from or around the element opening and inside the tank. 16. Replace terminal cover on thermostat making sure the locking tabs on the terminal cover are in place. 9. If you are cleaning the element you have removed, do so by scraping or soaking in vinegar or a deliming solution. 17. Fold back the insulation so that it covers the thermostat and element. 18. Replace outer door.
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. 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 17) 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.
