21 Housekeeping Vacuum around base of water heater for dust, dirt, and lint on a regular basis. AT LEAST ONCE EVERY SIX MONTHS A VISUAL INSPECTION SHOULD BE MADE OF THE AIR INTAKE SCREEN. CLEAN IF LINT ACCUMULATIONS ARE NOTICED. INSTALLED IN SUITABLE AREA: To insure sufficient ventilation and combustion air supply, proper clearances from the water heater must be maintained. See Facts to Consider About the Location section. Combustible materials such as clothing, cleaning materials, or flammable liquids, etc. must not be placed against or adjacent to the water heater because they could catch on fire. Anode Rod Each heater contains at least one anode rod, which will slowly deplete while protecting the glass-lined tank from c o r r o s i o n a n d p r o l o n g i n g t h e l i f e o f t h e w a t e r h e a t e r. Once the anode is depleted, the tank will start to corrode, eventually developing a leak. 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. The following are typical (but not all) signs of a depleted anode rod: • The majority of the rod’s diameter is less than 3/8”. • Significant sections of the support wire (approx. 1/3 or more of 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. In situations where clearance above the water heater is limited it may be necessary to bend the anode rod for removal. Flexible anode rods are available for replacement. In replacing the anode: 1. Turn off gas supply to the water heater. 2. Shut off the water supply and open a nearby hot water faucet to depressurize the water tank. 3. Drain approximately 5 gallons of water from tank (Refer to the “Draining and Flushing” section for proper procedures). Close drain valve. 4. Remove old anode rod. 5. Use Teflon ® tape or approved pipe sealant on threads and install new anode rod. 6. Turn on water supply and open nearby hot water faucet to purge air from water system. Check for any leaks and immediately correct any if found. 7. Restart the water heater as directed under the “Operating Your Water Heater” section. See the “Repair Parts Illustration” section for anode rod location. Temperature-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 not cause any property damage, as the water may be extremely hot, see Figure 25. FIGURE 25. 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.
22 Drain Valve Washer Replacement (See Figure 26) 1. Turn “OFF” gas supply to water heater. 2. Follow “Draining” instructions. 3. Turning counter clockwise ( ), remove the hex cap below the screw handle. 4. Remove the washer and put the new one in place. 5. Screw the handle and cap assembly back into the drain valve and retighten using a wrench. DO NOT OVER TIGHTEN. 6. Follow instructions in the Filling The Water Heater section. 7. Check for leaks. 8. Follow the lighting instructions in the Lighting section to restart the water heater. FIGURE 26. Service Before calling for repair service, read the Start Up Conditions and Operational Conditions found in the Troubleshooting Guide of this manual. If a condition persists or you are uncertain about the operation of the water heater, let the Sears Service Center check it out. Contact Sears Service Center at: 1-800-4-MY-HOME® (1-800-469-4663). 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 the Sears Service Center for further information. Do not plug 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 the gas control knob to the “OFF” position. 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. OPEN the water heater drain valve to allow for tank draining. NOTE: If the water heater is going to be shut down and drained for an extended period, the drain valve should be left open with hose connected allowing water to terminate to an adequate drain. 6. Close the drain valve. 7. Follow instructions in the Filling The Water heater section. 8. Follow the lighting instructions in the Lighting section to restart the water heater.
23 TROUBLESHOOTING GUIDE Start Up Conditions Thermal Expansion Water supply system may, because of such events as high line pressure, frequent cut-offs and the effects of water hammer 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 water heater’s temperature-pressure relief valve is reached, the valve will relief 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. 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. Thermal expansion tanks are available from Sears stores and through the Sears Service Centers. Contact the local plumbing inspector, water supplier and/or the Sears Service Center for assistance in controlling these situations, see Figure 27.

NOTE: Expansion tanks are pre-charged with a 40 psi air charge. If the inlet water pressure is higher than 40 psi, the expansion tank’s air pressure must be adjusted to match that pressure, but must not be higher than 80 psi. FIGURE 27. Strange Sounds Possible noises due to expansion and contraction of some metal parts during periods of heat-up and cool-down do not represent harmful or dangerous conditions. Condensation causes sizzling and popping within the burner area during heating and cooling periods and should be considered normal. See Condensation section. Draft Hood Operation Check draft hood operation by performing a worst case depressurization of the building. With all doors and windows closed, and with all air handling equipment and exhaust fans operating such as furnaces, clothes dryers, range hoods and bathroom fans, a match flame should still be drawn into the draft hood of the water heater with its burner firing. If the flame is not drawn toward the draft hood, shut off water heater and make necessary air supply changes to correct.
24 Condensation Whenever the water heater is filled with cold water, some condensate will form while the burner is on. A water heater may appear to be leaking when in fact the water is condensation. This usually happens when: • A new water heater is filled with cold water for the first time. • Burning gas produces water vapor In water heaters, particularly high efficiency models where flue temperatures are lower. • Large amounts of hot water are used in a short time and the refill water in the tank is very cold. Moisture from the products of combustion condense on the cooler tank surfaces and form drops of water which may fall onto the burner or other hot surfaces to produce a “sizzling” or “frying” noise. Excessive condensation can cause pilot outage due to water running down the flue tube onto the main burner and putting out the pilot. Because of the suddenness and amount of water, condensation water may be diagnosed as a “tank leak”. After the water in the tank warms up (about 1-2 hours), the condition should disappear. Do not assume the water heater is leaking until there has been enough time for the water in the tank to warm up. An undersized water heater will cause more condensation. The water heater must be sized properly to meet the family’s demands for hot water including dishwashers, washing machines and shower heads. Excessive condensation may be noticed during the winter and early spring months when incoming water temperatures are at their lowest. Good venting is essential for a gas fired water heater to operate properly as well as to carry away products of combustion and water vapor. Smoke Odor It is not uncommon to experience a small amount of smoke and odor during the initial start-up. This is due to burning off of oil from metal parts, and will disappear in a short while. Operational Conditions Smelly Odor In each water heater there is installed at least one anode rod (see parts section) 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”. 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 concentration of sulfate in the supply water. • little or no dissolved oxygen in the water. • a sulfate reducing bacteria within the water heater. (This harmless bacteria is non-toxic to humans.) • 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 Sears Service for further information concerning an Anode Replacement Kit #9001453 and this Chlorination Treatment. Anode replacement and chlorination of the tank are not covered by the water heater’s limited warranty. If the smelly water persists after the anode replacement and chlorination treatment, it may be necessary to chlorinate or aerate your water supply to eliminate the problem. Do 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. High Temperature Shut Off System This water heater is equipped with an automatic gas shutoff system. This system works when high water temperatures are present. Turn “OFF” the entire gas supply to the water heater. The high temperature shutoff is built into the gas control valve. It is non-resettable. If the high temperature shutoff activates, the gas control valve must be replaced. Contact your gas supplier.
25 Operational Conditions (Continued) Leakage Checkpoints FIGURE 28. Read this manual first. Then before checking the water heater make sure the gas supply has been turned “OFF”, and never turn the gas “ON” before the tank is completely full of water. Never use this water heater unless it is completely filled with water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater, see Figure 28. A. Water at the draft hood is water vapor which has condensed out of the combustion products. This is caused by a problem in the vent. Contact the gas utility. B. *Condensation may be seen on pipes in humid weather or pipe connections may be leaking. C. *The anode rod fitting may be leaking. D. Small amounts of water from temperature-pressure relief valve may be due to thermal expansion or high water pressure in your area. E. *The temperature-pressure relief valve may be leaking at the tank fitting. F. Water from a drain valve may be due to the valve being slightly opened. G. *The drain valve may be leaking at the tank fitting. H. Combustion products contain water vapor which can condense on the cooler surfaces of the tank. Droplets form and drip onto the burner or run on the floor. This is common at the time of start-up after installation and when incoming water is cold. I. 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.
