Location Requirements Site location Select a location near the center of the water piping system. It must be installed indoors and in a vertical position on a level surface. The water heater should be located in an area not subject to freezing temperatures. Water heaters located in unconditioned spaces (i.e., attics, basements, etc.) May require the water piping and drain piping to be insulated to protect against freezing. The drain and controls must be easily accessible for operation and service. Do not use this water heater in conjunction with a spa or hot tub. Note: Local codes and requirements in your area may require the installation of your water heater be accomplished in a way that the bottom element is elevated from the floor at least 18 inches. Important: The water heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the water heater or to lower floors of the structure. Due to the normal corrosive action of the water, the tank will eventually leak after an extended period of time. It is recommended that a suitable drain pan be installed under the water heater as shown below. This pan is to protect the property from damage which may occur from normal condensate formation on the tank or leaks in the tank and pipe connections. The pan must limit the water level to a maximum depth of 2-1/2 inches and be two inches wider than the heater and piped to an adequate drain. Locate the water heater near a suitable indoor drain. Outside drains are subject to freezing temperatures which can obstruct the drain line. The piping should be at least 3/4" ID and pitched for proper drainage. Under no circumstance will the manufacturer be held liable for any water damage in connection with this water heater. 2 1/2" MAX t PIPE TO ADEQUATE DRAIN AT LEAST 2" INCHES GREATER THAN THE DIAMETER OF THE WATER HEATER. 4 FIGURE 1 RESIDENTIAL GARAGE INSTALLATION VEHICLE STOP DRAIN_ PAN DRAIN State of California Note: The water heater must be braced, anchored, or strapped to avoid moving during an earthquake.

If the indoor installation area is subject to freezing temperatures, the water piping must be protected by insulation. Water supply pressure should not exceed 80% of the working pressure of the water heater. The working pressure is stated on the water heater's data plate. If this occurs a pressure limiting valve with a bypass may need to be installed in the cold water supply line. This should be placed on the supply to the entire house in order to maintain equal hot and cold water pressures. Important: Heat cannot be applied to the water fittings on the heater as they may contain nonmetallic parts. If solder connections are used, solder the pipe to the adapter before attaching the adapter to the hot and cold water fittings. Important: Always use a good grade of joint compound and be certain that all fittings are drawn up tight. 1. Install the water piping and fittings as shown in the Figure 6. Connect the cold water supply (3/4 NPT) to the fitting marked "C". Connect the hot water supply (3/4 NPT) to the fitting marked "H". Important: Some models may contain energy saving heat traps to prevent the circulation of hot water within the pipes. Do not remove these inserts. 2. The installation of unions in both the hot and cold water supply lines are recommended for ease of removing the water heater for service or replacement. 3. The manufacturer of this water heater recommends installing a tempering valve in the domestic hot water line as shown in Figures 7 and 8. These valves reduce the point-of-use temperature of the hot water by mixing cold and hot water and are readily available. Contact a licensed plumber or the local plumbing authority. If installing the water heater in a closed water system, install a relief valve or expansion tank in the cold water line as specified under "Closed System/Thermal Expansion". 5. Install a shut off valve in the cold water inlet line. It should be located close to the water heater and be easily accessible. Know the location of this valve and how to shut off the water to the heater.

After piping has been properly connected to the water heater, open the nearest hot water faucet and allow the tank to completely fill with water. To purge the lines of any excess air and sediment, keep the hot water faucet open for 3 minutes after a constant flow of water is obtained. Close the faucet and check all connections for leaks. t TEMPERED WATER TO FIXTURES TEMPERING VALVE (SETTO 120 ° F) Please note the following: DO NOT install this water heater with iron piping. The system should be installed only with new piping that is suitable for potable (drinkable) water such as copper, CPVC, or polybutylene. DO NOT use PVC water piping. Temperature Relief Valve and Pressure DO NOT use any pumps, valves, or fittings that are not compatible with potable water. DO NOT use valves that may cause excessive restriction to water flow. Use full flow ball or gate valves only. DO NOT use 50/50 tin-lead solder (or any lead based solder) in potable water lines. Use 95/5 tin-antimony or other equivalent material. DO NOT tamper with the thermostat, heater elements, electrical connections, or temperature and pressure relief valve. Tampering voids all warranties. Only qualified technicians should service these components. DO NOT use with piping that has been treated with chromate's, boiler seal, or other chemicals. DO NOT add any chemicals to the system piping which will contaminate the potable water supply. Closed System/Thermal Expansion Periodic discharge of the temperature and pressure relief valve may be due to thermal expansion in a closed water supply system. The water utility supply meter may contain a check valve, backflow preventer or water pressure reducing valve. This will create a closed water system. During the heating cycle of the water heater, the water expands causing pressure inside the water heater to increase. This may cause the temperature and pressure relief valve to discharge small quantities of hot water. To prevent this from happening, there are two recommendations: , 2. Install a diaphragm-type expansion tank that is suitable for potable water on the cold water supply line. The expansion tank must have a minimum capacity of 1.5 U.S. gallons for every 50 gallons of stored water. Install a 125 PSI pressure relief valve in the cold water supply line. Make sure the discharge of this valve is directed to an open drain and protected from freezing. Contact the local water supplier or plumbing inspector for information on how to control this situation. Do not plug the temperature and pressure relief valve. Explosion Hazard If the temperature and pressure relief valve is dripping or leaking, have a licensed plumber repair it. Do not plug valve. Do not remove valve. Failure to follow these instructions result in death, or explosion. FIGURE 9 TEMPERATURE RELIEF VALVE AND PRESSURE INSTALLATION OPTIONAL F {_ LOCATION PRESSURE VALVE DISCHARGE LINE 3/4 INCH MIN. DO NOT DRAIN can CAP OR PLUG PAN [ DRAIN For protection against excessive pressures and temperatures, a temperature and pressure relief valve must be installed in the opening marked "T & P RELIEF VALVE" (See Figure 9). Caution: To reduce the risk of excessive pressures and temperatures in this water heater, install temperature and pressure relief protective equipment required by local codes, but no less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of the production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 - 1986. This valve must be marked with the maximum set pressure not to exceed the marked maximum working pressure of the water heater. Install the valve into an opening provided and marked for this purpose in the water heater, and orient it or provide tubing so that any discharge from the valve exits only within 6 inches above, or at any distance below, the structural floor, and does not contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstance.

OPERATING YOUR WATER HEATER Before operating the water heater, perform the following: 1. Make sure the water heater has been properly installed. 2. Water Temperature Regulation Completely fill the tank with water. (See Figure 2) 3. Apply power to the water heater only after the tank is completely filled with water. 4. Carefully read and understand the "Water Temperature Regulation" section of this manual. 5. Adjust the thermostat to the desired temperature setting as directed under "Adjusting the Thermostat/ High Limit Control". Important: Do not attempt to operate this water heater if the thermostat(s), or surrounding insulation has been exposed to water in any way. Immediately call a qualified service technician to inspect the water heater and replace any thermostat or insulation that has been exposed to water. Do not attempt to repair these parts. Water heaters subjected to flood conditions or any time the thermostat(s) have been submerged in water require replacement of the entire water heater. Safety Shut-off This water heater is designed to automatically shut-off in the event that the water temperature exceeds 170°F (77°C). A high limit control switch is used to shut off the power to the elements if the water temperature exceeds 170°F (77°C). The high limit control can be reset by firmly pushing in the red reset button located on the thermostat. Follow the instructions under "Adjusting the Thermostat/High Limit Control" to properly reset the high limit control. Water temperature over 125°F can cause severe burns instantly or death from scalds. Children, disabled and elderly highest risk of being scalded. are at See instructions manual before temperature at water heater. Feel water before Temperature bathing setting or showering. limiting valves are available. The thermostat is adjusted to a temperature setting of 120°F or lower when it is shipped from the factory. Water temperature can be regulated by adjusting the thermostat to the preferred setting as shown in "Adjusting the Thermostat/High limit Control." The preferred starting point is 120°F. There is a hot water scald potential if the thermostat is set too high. Important: Adjusting the thermostat past 120°F on the thermostat will increase the risk of scald injury. Hot water can produce first degree burns within: 120°F (49°C) more than 5 minutes 130°F (54°C) at 20 seconds 140°F (60°C) at 3 seconds 150°F (66°C) at 1-1/2 seconds 160°F (71°C) at less than 1 second During low demand periods when hot water is not being used, a lower thermostat setting will reduce energy losses and may satisfy your normal hot water needs. If hot water use is expected to be more than normal, a higher thermostat setting may be required to meet the increased demand. When leaving your home for extended periods (vacations, etc.) turn the thermostat to its lowest setting. This will maintain the water at low temperatures with minimum energy losses and prevent the tank from freezing during cold weather. Adjusting the Thermostat/High Limit Control This water heater is equipped with one or more adjustable temperature regulating thermostats and a manual reset high limit control. The following procedures must be performed when changing the temperature of the stored water or resetting the high limit control. Upper and lower thermostats must be adjusted to the same temperature. Before attempting to adjust the thermostat, make sure you read and understand the section of "Water Temperature Regulation". Any other adjustments must be made by qualified service personnel. 1. Shut-off the power to the water heater. 2. Remove the access cover(s) and fold the insulation outward and away from the thermostat(s). remove the plastic cover. Do not 3. Using a screwdriver to adjust the thermostat pointer, set the thermostat(s) to the desired water temperature. Be sure the RED reset button (High Limit Control) is properly set: push in firmly to reset. 4. Replace the insulation. Make sure the thermostat(s) are well covered. Replace the access cover(s). 5. Apply power to the water heater. FIGURE 10 THERMOSTAT THERMOSTAT/HIGH LIMIT CONTROL ® ® OPTIONAL DOOR RED RESET UTTON ® ® ACCESS COVERS ACCESS COVER SCREW SLOT 125o F DOUBLE ELEMENT HEATER 10 THERMOSTATSETTING AND ADJUSTMENT SINGLE ELEMENT HEATER Operation Conditions Anode Rod/Water Odor Each water heater contains at least one anode rod, which will slowly deplete while protecting the glass-lined tank from corrosion and prolonging the life of the water heater. Certain water conditions will cause a reaction between this rod and the water. Once the anode is depleted, the tank will start to corrode, eventually developing a leak. The most common complaint associated with the anode rod is a "rotten egg smell" produced from the presence of hydrogen sulfide gas dissolved in the water. Do not remove this rod permanently as it will void any warranties, stated or implied. The parts list includes a special anode that can be ordered if water odor or discoloration occurs. This rod may reduce but not eliminate water odor problems. The water supply system may require special filtration equipment from a water conditioning company to successfully eliminate all water odor problems. Artificially softened water is exceedingly corrosive because the process substitutes sodium ions for magnesium and calcium ions. The use of a water softener may decrease the life of the water heater tank. The anode rod should be removed from the water heater tank every 3 years for inspection. If the rod is more than 50% depleted, the anode rod should be replaced. For replacing the anode, shut-off the power to the water heater. Be sure the cold water supply to the heater is turned off. Open the hot water faucet to depressurize the water tank. Drain out 5 gallons of water from the drain valve at the bottom of the heater. Remove the anode rod. See the "Repair Parts Illustration" for anode rod location on page 15. Water Heater Sounds During the normal operation of the water heater, sounds or noises may be heard. These noises are common and may result from the following: 1. Normal expansion and contraction of metal parts during periods of heat-up and cool-down. 2. Sediment buildup in the tank bottom will create varying amounts of noise and may cause premature tank failure. Drain and flush the tank as directed under "Draining and Flushing". Maintenance Temperature Relief Valve and Pressure Explosion Hazard If the temperature and pressure relief valve is dripping or leaking, have a licensed plumber repair it. Do not plug valve. Do not remove valve. Failure to follow these instructions result in death, or explosion. can Manually operate the temperature and pressure relief valve at least once a year to make sure it is working properly. To prevent water FIGURE 11 damage, the valve must I TEMPERATURE AND PRESSURE be properly connected to I RELIEF VALVE a discharge line which terminates at an adequate drain. Standing clear of the outlet (discharged water may be hot), slowly lift and release the lever handle DISCHARGE LINE TO DRAIN on the temperature and pressure relief valve to allow the valve to operate freely and return to its closed position. If the valve fails to completely reset and continues to release water, immediately shut-off the electrical power and the cold water inlet valve and call a qualified service technician. Stacking Stacking occurs when a series of short draws of hot water (3 gallons or less) are taken from the water heater tank. This causes increased cycling of the heater elements and can result in increased water temperatures at the hot water outlet. An anti-scald device is recommended in the hot water supply line to reduce the risk of scald injury. 11 Draining and Flushing The water heater should be drained if being shut down during freezing temperatures. It is recommended that the tank be drained, and flushed every 6 months to remove sediment which may buildup during operation. To drain the tank perform the following steps: Heating Element Replacement Electrical 1. Turn off the power to water heater. Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock. 2. Close the cold water inlet valve and open a nearby hot water faucet. 3. Connect a hose to the drain valve and terminate it to an adequate drain. Important: Drain hose should be rated for at least 200°F. If the drain hose does not have this rating, open the cold water inlet valve and a nearby hot faucet until water is no longer hot 4. Open the water heater drain valve and the nearest hot water faucet. Allow all the water to drain from the tank. Flush the tank with water as needed to remove sediment. Shock Hazard Replacement heating elements must be of the same style and voltage/wattage rating as the ones presently in the water heater. This information can be found on the flange or terminal block of the element or on the water heater data plate. 1. Shut-off the electric power to the water heater. 5. Close the drain valve, refill the tank, and restore power. 2. Drain the water heater as directed under "Draining and Flushing". If the water heater is going to be shut down for an extended period, the drain valve should be left open. 3. Remove the access cover(s). Fold the insulation outward and away from the heater element(s). Remove the plastic thermostat cover from the thermostat(s) making sure to disengage the attachment point from the thermostat. 4. Disconnect the electric wires from the heating element (Figure 13). Remove the screw-in elements by turning the element counterclockwise with a 1-1/2 inch socket wrench. Remove the existing gasket. NOTE: When draining Table Top models, remove the screw securing the drain access cover. Remove the cover by pulling down and away from the water heater.
