wirinG Never use the water heater unless it is completely full of water. To prevent damage to the tank and the heating element, the tank must be filled with water. Water must flow from the hot water faucet before turning on the power. You must provide all wiring of the proper size outside of the water heater. You must obey the local codes and the electric company requirements when you install this wiring. This water heater is supplied with a flexible, grounded power cord and connects to a standard three-wire 120 volt 60Hz, grounded type outlet. If an outlet is not within reach of the power cord, contact a local electrician/electrical contractor or the local electric utility to have a properly sized circuit (including outlet, wiring and breaker) installed. NOTE: Check the water heater ’s data plate for power requirements. If you are not familiar with the electric codes and practices, or if you have any doubt, even the slightest doubt, in your ability to connect the wiring to this water heater, obtain the service of a competent electrician. Contact a local electrical contractor and/or the local electric utility. WATER HEATERS EQUIPPED FOR ONE VOLTAGE ONLY: This water heater is equipped for one type voltage only. Check the rating plate near the bottom access panel for the correct voltage. DO NOT use this water heater with any voltage other than the one shown on the model rating plate. Failure to use the correct voltage can cause problems which can result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any questions or doubts consult your electric company. If wiring from your fuse box or circuit breaker box was aluminum for your old water heater, replace it with copper wire. If you wish to reuse the existing aluminum wire, have the connection at the water heater made by a competent electrician. Contact a local electrical contractor and/or the local electric utility.

3 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. As water is heated, it expands (thermal expansion) and closed systems do not allow for the expansion of heated water. 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. t he temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This is an unacceptable condition and must be corrected. It is recommended that any devices installed which could create a closed system have a by-pass and/or the system have an expansion tank or device to relieve the pressure built by thermal expansion in the water system. Expansion tanks are available for ordering through a local plumbing contractor. Contact the local water heater supplier or service agency for assistance in controlling these situations. stran Ge sounds Possible noises due to expansion and contraction of some metal parts during periods of heat-up and cool-down do not necessarily represent harmful or dangerous conditions. operational conditions w ater odor In each water heater there is installed at least one anode rod (see parts sections) for corrosion protection of the tank. Certain water conditions will cause a reaction between this rod and the water. The most common complaint associated with the anode rod is one of a “rotten egg smell” in the hot water. This odor is derived from hydrogen sulfide gas dissolved in the water. The smell is the result of four factors which must all be present for the odor to develop: A. A concentration of sulfate in the supply water. B. Little or no dissolved oxygen in the water. C. A sulfate reducing bacteria which has accumulated within the water heater (this harmless bacteria is nontoxic to humans). D. An excess of active hydrogen in the tank. This is caused by the corrosion protective action of the anode. Smelly water may be eliminated or reduced in some water heater models by replacing the anode(s) with one of less active material, and then chlorinating the water heater tank and all hot water lines. Contact the local water heater supplier or service agency for further information concerning an Anode Replacement Kit and this chlorination treatment. If the smelly water persists after the anode replacement and chlorination treatment, we can only suggest that chlorination or aeration of the water supply be considered to eliminate the water problem. d o not remove the anode leaving the tank unprotected. By doing so, all warranty on the water heater tank is voided. “air” in hot water faucets HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the possibility of injury under these conditions, we recommend the hot water faucet, located farthest away be opened for several minutes before any electrical appliances which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open. hi Gh water temperature shut off sYstem A non-adjustable high temperature limit control operates before steam temperatures are reached. The high limit switch must be reset manually when it operates. BECAUSE THE HIGH LIMIT OPERATES ONLY WHEN ABNORMALLY HIGH WATER TEMPERATURES ARE PRESENT, IT IS IMPORTANT THAT A QUALIFIED SERVICE AGENT BE CONTACTED TO DETERMINE THE REASON FOR OPERATION BEFORE RESETTING . • Turn off and unplug the water heater. Do not attempt to reset thermostat with power on. • Remove the front panel, see “Removing Front Panel” in the Periodic Maintenance section. • Remove the insulation to expose the reset button. • Reset the high limit by pushing in the red button. • Replace the insulation so that it completely covers the thermostat and element. • Replace the front panel. • Plug in and turn on the water heater. for Your information
not cause any property damage, as the water may be extremely hot, see Figure 7. fiGure 7. 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. You may have a check valve installed in the water line or a water meter with a check valve. Consult your local water supplier or service agency for further information. Do not plug or remove the temperature-pressure relief valve. draininG 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 off and unplug the water heater from the electrical outlet. 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. Disconnect water connections. Remove unit from wall. UNIT WILL BE HEAVY. Turn unit upside down and drain unit into a suitable drain or receptacle. removinG the front panel 1. Turn off and unplug the water heater from the electrical outlet and follow “DRAINING INSTRUCTIONS.” 2. Remove the temperature knob by pulling straight out. 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. This does not affect the water’s taste or color. The rod must be maintained to keep the tank in operating condition. NOTE: Artificially softened water is more 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. A n o d e d e t e r i o r a t i o n d e p e n d s o n w a t e r c o n d u c t i v i t y, n o t necessarily water condition. A corroded or pitted anode rod indicates high water conductivity and should be checked and/or replaced more often than an anode rod that appears to be intact. Replacement of a depleted anode rod can extend the life of your water heater. Inspection should be conducted by a qualified technician, and at a minimum should be checked every three years. The anode rod in this unit is attached to the element flange. For removal instructions, see “ EL EMENT CLEANING / R EPLACEMENT .” Ty p i c a l ( b u t n o t a l l ) s i g n s o f a d e p l e t e d a n o d e r o d a r e a s follows: • T he majority of the rods diameter is less than 3/8” • Significant sections of the support wire (approximately 1/3 or more o f the anode rod’s length) are visible. If the anode rod shows signs of either or both it should be replaced. NOTE: Whether re-installing or replacing the anode rod, check for any leaks and immediately correct if found. t emperature- pressure relief valve operation The temperature-pressure relief valve must be manually operated at least once a year. When checking the temperature-pressure relief valve operation, make sure that (1) no one is in front of or around the outlet of the temperature- pressure relief valve discharge line, and (2) that the water discharge will periodic maintenance

7 leaKaGe checKpoints Read this manual first. 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. If the valve is not piped to an open drain the released water could be mistaken for a leaking heater, see “Thermal Expansion” section. *C. The temperature-pressure relief valve may be leaking at the tank fitting. D. Water on the side of the tank may be condensation due to the panel or insulation not being in place. *E. Water in the water heater bottom or on the floor may be from condensation, loose connections, or the relief valve. DO NOT replace the water heater until a full inspection of all possible water sources is made and necessary corrective steps taken. Leakage from other appliances, water lines, or ground seepage should also be checked. * To check where threaded portion enters tank, insert cotton swab between jacket opening and fitting. If cotton is wet, follow “Draining” instructions in the “Periodic Maintenance” section and then remove fitting. Put pipe dope or teflon tape on the threads and replace. Then follow “Filling the Water Heater” instructions in the “Installing the New Water Heater” section. Key no. part description fiGure 12.
