4. Attach a hose to the water heater drain valve and put the other end in a fl oor drain or outdoors. Open the water heater drain valve. Open a nearby hot water faucet which will relieve pressure in the water heater and speed draining. The water passing out of the drain valve may be extremely hot. To avoid being scalded, make sure all connections are tight and that the water fl ow is directed away from any person, see Figures 2 and 5.
5. Disconnect the vent pipe from the draft hood where it connects to the water heater. In most installations the vent pipe can be lifted off after any screw or other attached devices are removed. Dispose of the draft hood. The new water heater has a draft hood which must be used for proper operation.
6. If you have copper piping to the water heater, the two copper water pipes can be cut with a hacksaw approximately four inches away from where they connect to the water heater, see Figure 6. This will avoid cutting off pipes too short. Additional cuts can be made later if necessary. Disconnect the temperature-pressure relief valve drain line. When the water heater is drained, disconnect the hose from the drain valve. Close the drain valve. The water heater is now completely disconnected and ready to be removed.
FIGURE 5.
1. Turn “OFF” the gas supply to the water heater.
If the main gas line shut-off valve
serving all gas appliances is used, also shut “OFF” the gas at each appliance. Leave all gas appliances shut “OFF” until the water heater installation is completed, see Figures 2 and 3.
2. Turn “OFF” the water supply to the water heater at the water shut­off valve or water meter. Some installations require that the water be turned off to the entire house, see Figures 2 and 4.
3. Check again to make sure the gas supply is “OFF” to the water heater. Then disconnect the gas supply connection from the gas control valve.
FIGURE 3.
FIGURE 4.
FIGURE 6.
If you have galvanized pipes to the water heater, loosen
the two galvanized pipes with a pipe wrench at the union in each line. Also disconnect the piping remaining to the water heater, see Figure 7. These pieces should be saved since they may be needed when reconnecting the new water heater. Disconnect the temperature-pressure relief valve drain line. When the water heater is drained, disconnect the hose from the drain valve. Close the drain valve. The water heater is now completely disconnected and ready to be removed. Mineral buildup or sediment may have accumulated in the old water heater. This causes the water heater to be much heavier than normal and this residue, if spilled out, could cause staining.

Facts to Consider About the Location
Carefully choose an indoor location for the new water heater, because the placement is a very important consideration for the safety of the occupants in the building and for the most economical use of the appliance. This water heater is not for use in
manufactured (mobile) homes or outdoor installation.
Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed:
• Select a location indoors as close as practical to the gas vent or chimney to which the water heater vent is going to be connected, and as centralized with the water piping system as possible.
• Selected location must provide adequate clearances for servicing and proper operation of the water heater.
Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the fl ow will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper fl oor. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are available at your local Sears or hardware store. 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. The pan must not restrict combustion air fl ow.
• Devices that will turn off the gas supply to a gas water heater while at the same time shutting off its water supply.
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS) ARE LIKELY TO BE PRESENT OR STORED (GARAGES, STORAGE AND UTILITY AREAS, ETC.): Flammable liquids (such as gasoline, solvents, propane [LP or butane, etc.] and other substances such as adhesives, etc.) emit fl ammable vapors which can be ignited by a gas water heater’s pilot light or main burner. The resulting fl ashback and fi re can cause death or serious burns to anyone in the area. Even though this water heater is a fl ammable vapors ignition resistant water heater and is designed to reduce the chances of fl ammable vapors being ignited, gasoline and other fl ammable substances should never be stored or used in the same vicinity or area containing a gas water heater or other open fl ame or spark producing appliance.
Also, the water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle.
Water heater life depends upon water quality, water pressure and the environment in which the water heater is installed. Water heaters are sometimes installed in locations where leakage may result in property damage, even with the use of a drain pan piped to a drain. However, unanticipated damage can be reduced or prevented by a leak detector or water shut-off device used in conjunction with a piped drain pan. These devices are available from some plumbing supply wholesalers and retailers, and detect and react to leakage in various ways:
• Sensors mounted in the drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected.
• Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan.
• Water supply shut-off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater.
This water heater must not be installed directly on carpeting. Carpeting must be protected by metal or wood panel beneath the appliance extending beyond the full width and depth of the appliance by at least 3 inches (76.2mm) in any direction, or if the appliance is installed in an alcove or closet, the entire fl oor must be covered by the panel. Failure to heed this warning may result in a fi re hazard.

Page 10
Minimum clearances between the water heater and combustible construction are 0 inch at the sides and rear, 4 inches (102 mm) at the front, and 6 inches (153 mm) from the vent pipe, see Figure 8. Clearance from the top of the jacket is 12 inches (305 mm) on most models. Note that a lesser dimension may be allowed on some models, refer to the label attached adjacent to the gas control valve on the water heater.
FIGURE 8.
FIGURE 9.
If this water heater will be used in beauty shops, barber shops, cleaning establishments, or self-service laundries with dry cleaning equipment, it is imperative that the water heater or water heaters be installed so that combustion and ventilation air be taken directly from outdoors (direct vent).
Propellants of aerosol sprays and volatile compounds, (cleaners, chlorine based chemicals, refrigerants, etc.) in addition to being highly fl ammable in many cases, will also change to corrosive hydrochloric acid when exposed to the combustion products of the water heater. The results can be hazardous, and also cause product failure.
Insulation Blankets
Insulation blankets available to the general public for external use on gas water heaters are not necessary with Kenmore products. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Your Kenmore water heater meets or exceeds the National Appliance Energy Conservation Act standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary.
A gas water heater cannot operate properly without the correct amount of air for combustion, see Figure 9. Do not install in a confi ned area such as a closet, unless you provide air as shown in the Locating The New Water Heater section. Never obstruct the fl ow of ventilation air. If you have any doubts or questions at all, call your gas supplier. Failure to provide the proper amount of combustion air can result in a fi re or explosion and cause death, serious bodily injury, or property damage.
WARNING
Should you choose to apply an insulation blanket to this heater, you should follow these instructions (See Figure 1 for identifi cation of components mentioned below). Failure to follow these instructions can restrict the air fl ow required for proper combustion, potentially resulting in fi re, asphyxiation, serious personal injury or death.

Page 11
• Do not apply insulation to the top of the water heater, as this will interfere with safe operation of the draft hood.
• Do not cover the outer door, thermostat or temperature & pressure relief valve.
• Do not allow insulation to come within 2” (50.8 mm) of the fl oor to prevent blockage of combustion air fl ow to the burner.
• Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.
• Do obtain new warning and instruction labels from Sears for placement on the blanket directly over the existing labels.
• Do inspect the insulation blanket frequently to make certain it does not sag, thereby obstructing combustion air fl ow.
within 12 inches (30 cm) of the top and one commencing within 12 inches (30 cm) of the bottom of the enclosures.
Combustion Air and Ventilation for Appliances Located in Unconfi ned Spaces
UNCONFINED SPACE is space whose volume is not less than
50 cubic feet per 1,000 Btu per hour (4.8 m aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed, through openings not furnished with doors, are considered a part of the unconfi ned space.
In unconfi ned spaces in buildings, infi ltration may be adequate to provide air for combustion, ventilation and dilution of fl ue gases. However, in buildings of tight construction (for example, weather stripping, heavily insulated, caulked, vapor barrier, etc.), additional air may need to be provided using the methods described in Combustion Air and Ventilation for Appliances Located in Confi ned Spaces.

If the design and free area is not known, it may be assumed that wood louvers will be 20-25 percent free area and metal louvers and grilles will have 60-75 percent free area. Louvers and grilles shall be fi xed in the open position or interlocked with the equipment so that they are opened automatically during equipment operation.
• Special Conditions Created by Mechanical Exhausting or Fireplaces: operation of exhaust fans, ventilation systems, clothes dryers or fi replaces may create conditions requiring special attention to avoid unsatisfactory operation of installed gas utilization equipment.
FIGURE 13A.
Water Piping
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 infi rm, or physically/mentally handicapped. If anyone using hot water in your home fi ts into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfi es your hot water needs, a means such as a *mixing valve should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores. See Figure 14. Valves for reducing point of use temperature by mixing cold and hot water are also available.
for installation of the valves. Before changing the factory setting on the thermostat, read the Temperature Regulation section in this manual.
Follow manufacturer’s instructions
• Alternatively, a single permanent opening may be used when communicating directly with the outdoors, or with spaces that freely communicate with the outdoors. The opening shall have a minimum free area of 1 square inch per 3,000 BTU per hour (8.3 cm²/kW) of total input rating of all equipment in the enclosure. See Figure 13A.

This water heater shall not be connected to any heating systems or component(s) used with a non-potable water heating appliance.
All piping components connected to this unit for space heating applications shall be suitable for use with potable water.
Toxic chemicals, such as those used for boiler treatment shall not be introduced into this system.
Water supply systems may, because of such events as high line pressure, frequent cut-offs or the effects of water hammer among others, have installed devices such as pressure reducing valves, check valves, back fl ow 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.
to the cold water inlet. It will harm the dip tube and damage the tank.
• Look at the top cover of the water heater. The water outlet is marked “HOT”. Put two or three turns of tefl on tape around the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4” NPT threaded nipple. Using fl exible connectors, connect the hot water pipe to the hot water outlet on the water heater.
• Look at the top of the water heater. The cold water inlet is marked “COLD”. Put two or three turns of tefl on tape around the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4” NPT threaded nipple. Using fl exible connectors, connect the cold water pipe to the cold water inlet of the water heater.
NOTE: This water heater is super insulated to minimize
heat loss from the tank. Further reduction in heat loss can be accomplished by insulating the hot water lines from the water heater.
INSTALLATION COMPLETED USING INSTALLATION KIT
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. 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 to relieve the pressure built by thermal expansion in the water system. Refer to the Thermal Expansion section under Troubleshooting Guide or contact local plumbing authority or local Sears Service Center on how to control this situation.
NOTE: To protect against untimely corrosion of hot and cold water fi ttings, it is strongly recommended that di-electric unions or couplings be installed on this water heater when connected to copper pipe.
FIGURE 15.
Figure 15 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 3/4” NPT water connections.
NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the cold water inlet connection. Do not solder the cold water supply line directly

T & P Valve and Pipe Insulation
Remove insulation for T & P valve and pipe connections from carton.
FIGURE 15A.
Fit pipe insulation over the incoming cold water line and the hot water line. Make sure that the insulation is against the top cover of the heater.
Fit T & P valve insulation over valve. Make sure that the insulation does not interfere with the lever of the T & P valve.
Secure all insulation using tape.
For safe operation of the water heater, the relief valve must not be removed from its designated opening nor plugged.
The temperature-pressure relief valve must be installed directly into the fi tting of the water heater designed for the relief valve. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches (153 mm) above, or at any distance below the structural fl oor, see Figure 16. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet (9.14 m), or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6 inch air gap is provided. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water fl ow may cause property damage.
Temperature-Pressure Relief Valve
This heater is provided with a properly certifi ed combination temperature - pressure relief valve by the manufacturer.
The valve is certifi ed by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment as meeting the requirements for Relief Valves for Hot Water Supply Systems, ANSI Z21.22 and the code requirements of ASME.
If replaced, the valve must meet the requirements of local codes, but not less than a combination temperature and pressure relief valve certifi ed as indicated in the above paragraph.
The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater input rate as shown on the model rating plate.
FIGURE 16.
The Discharge Pipe:
• 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.
• Shall be of material listed for hot water distribution.
• Shall be installed so as to allow complete drainage of both
14
Page 15
the temperature-pressure relief valve, and the discharge pipe.
• Shall terminate at an adequate drain.
• Shall not have any valve between the relief valve and tank.
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 temperature­pressure 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.
• Check all water piping and connections for leaks. Repair as needed.
Venting
VENT DAMPERS - Any vent damper, whether it is operated thermally or otherwise must be removed if its use inhibits proper drafting of the water heater.
Thermally Operated Vent Dampers: Gas-fi red water heaters having thermal effi ciency in excess of 80% may produce a relatively low fl ue gas temperature. Such temperatures may not be high enough to properly open thermally operated vent dampers. This would cause spillage of the fl ue gases and may cause carbon monoxide poisoning.
Vent dampers must bear evidence of certifi cation as complying with the current edition of the American National Standard ANSI Z21.68 (ANSI Z21.66 & 67, respectively, cover electrically and mechanically actuated vent dampers). Before installation of any vent damper, consult your local Sears Service Center or the local gas supplier for further information.
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.
Filling the Water Heater
Never use this water heater unless it is completely full of water. To prevent damage to the tank, the tank must be fi lled with water. Water must fl ow from the hot water faucet before turning “ON” gas to the water heater.
To fi ll the water heater with water:
• 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.
• 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.
• To ensure complete fi lling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant fl ow is obtained. This will let air out of the water heater and the piping.
To ensure proper venting of this gas-fi red water heater, the correct vent pipe diameter must be utilized. Any additions or deletions of other gas appliances on a common vent with this water heater may adversely affect the operation of the water heater. Consult your gas supplier if any such changes are planned. For replacement heater installations where using pre­existing venting, venting must be inspected for obstructions and if deterioration is present, venting must be replaced.
For proper venting in certain installations, a larger diameter vent pipe may be necessary. Consult your local Sears Service Center or gas supplier to aid you in determining the proper venting for your water heater from the vent tables in the current edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54.
Periodically check the venting system for signs of obstruction or deterioration and replace if needed.
The combustion and ventilation air flow must not be obstructed.
15
Page 16
The water heater with draft hood installed must be connected to a chimney or listed vent pipe system, which terminates to the outdoors. Never operate the water heater unless it is vented to the outdoors and has adequate air supply to avoid risks of improper operation, explosion or asphyxiation.
• For proper draft hood attachment, the draft hood legs may be angled slightly inward.
• Place the draft hood legs in the receiving holes on the top of the water heater. The legs will snap in the holes to give a tight fi t. Secure two legs to top with sheet metal screws.
• Place the vent pipe over the draft hood. With the vent pipe in position, drill a small hole through both the vent pipe and draft hood. Secure them together with a sheet metal screw. See Figure 17.
Obstructed or deteriorated vent systems may present serious health risk or asphyxiation.
Failure to have required clearances between vent piping and combustible material will result in a fi re hazard. Be sure vent pipe is properly connected to prevent escape of dangerous fl ue gases which could cause deadly asphyxiation. Chemical vapor corrosion of the fl ue and vent system may occur if air for combustion contains certain chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes, bleach and process chemicals are typical
compounds which are potentially corrosive.
FIGURE 17.
The vent pipe from the water heater must be no less than the diameter of the draft hood outlet on the water heater and must slope upward at least 1/4 inch per linear foot (21 mm per meter). See Figure 18.
FIGURE 18.
All vent gases must be completely vented to the outdoors of the
structure (dwelling). Install only the draft hood provided with the new water heater and no other draft hood.
Vent pipes must be secured at each joint with sheet metal screws.
There must be a minimum of 6 inches (153 mm) clearance between single wall vent pipe and any combustible material. Fill and seal any clearance between single wall vent pipe and combustible material with mortar mix, cement, or other noncombustible substance. For other than single wall, follow vent pipe manufacturer’s clearance specifi cations. To insure a tight fi t of the vent pipe in a brick chimney, seal around the vent pipe with mortar mix cement.
Gas Piping
Make sure the gas supplied is the same type listed on the model rating plate. The inlet gas pressure must not exceed 14 inch water column (3.5kPa) for natural and propane gas (L.P.) gas. The minimum inlet gas pressure listed on the rating plate is for the purpose of input adjustment. is subjected to pressures exceeding 1/2 pound per square inch (3.5kPa), the damage to the gas control valve could result in a fi re or explosion from leaking gas.
If the main gas line shutoff serving all gas appliances is used, also turn “OFF” the gas at each appliance. Leave all gas appliances shut “OFF” until the water heater installation is complete.
A gas line of suffi cient size must be run to the water heater. Consult the current edition of National Fuel Gas Code ANSI Z223.1/NFPA 54 and your gas supplier concerning pipe size.
16
If the gas control valve
Page 17
There must be:
• A readily accessible manual shut off valve in the gas supply line serving the water heater, and
• A drip leg (sediment trap) ahead of the gas control valve to help prevent dirt and foreign materials from entering the gas control valve.
• A fl exible gas connector or a ground joint union between the shut off valve and control valve to permit servicing of the unit.
Be sure to check all the gas piping for leaks before lighting the water heater. Use a soapy water solution, not a match or open fl ame. Rinse off soapy solution and wipe dry.
The minimum inlet gas pressure shown on the rating plate is that which will permit fi ring at the rated input.
The appliance and its gas connection must be leak tested before placing the appliance in operation.
The appliance and its individual shutoff valve shall be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 pound per square inch (3.5kPa). It shall be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 pound per square inch (3.5kPa).
Connecting the gas piping to the gas control valve of the water heater can be accomplished by either of the two methods shown in Figures 19 and 20.
Sediment Traps
Water heaters covered in this manual have been tested and approved for installation at elevations up to 7,700 feet (2,347 m) above sea level. For installation above 7,700 feet (2,347m), the water heater’s Btu input should be reduced at the rate of 4 percent for each 1,000 feet (305 m) above sea level which requires replacement of the burner orifi ce in accordance with the National Fuel Gas Code ANSI Z223.1/NFPA 54. Contact your local gas supplier for further information.
Failure to replace the standard orifi ce with the proper high altitude orifi ce when installed at elevations above 7,700 feet (2,347m) could result in improper and ineffi cient operation of the appliance, producing carbon monoxide gas in excess of the safe limits. This could result in serious injury or death. Contact your local gas supplier for any specifi c changes that may be required in your area.
Contaminants in the gas lines may cause improper operation of the gas control valve that may result in fi re or explosion. Before attaching the gas line be sure that all gas pipe is clean on the inside. To trap any dirt or foreign material in the gas supply line, a drip leg (sometimes called a sediment trap) must be incorporated in the piping. The drip leg must be readily accessible. Install in accordance with the Gas Piping section. Refer to the current edition of th
ANSI Z223.1/NFPA 54.
A sediment trap shall be installed as close to the inlet of the water heater as practical at the time of water heater installation. The sediment trap shall be either a tee fi tting with a capped nipple in the bottom outlet or other device recognized as an effective sediment trap. If a tee fi tting is used, it shall be installed in conformance with one of the methods of installation, shown in Figures 19 and 20.

Temperature Regulation
Due to the nature of the typical gas water heater, the water temperature in certain situations may vary up to 30F° (16.7 C°) higher or lower at the point of use such as, bathtubs, showers, sink, etc.
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. These include the elderly, children, the infi rm, or physically/mentally handicapped. If anyone using hot water in your home fi ts into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfi es your hot water needs, a means such as a mixing valve should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, see Figures 21 and 22.
THE WATER HEATER SHOULD BE LOCATED IN AN AREA WHERE THE GENERAL PUBLIC DOES NOT HAVE ACCESS. IF A SUITABLE AREA IS NOT AVAILABLE, A COVER SHOULD BE INSTALLED OVER THE THERMOSTAT TO PREVENT TAMPERING. Suitable covers are available through the Sears Service Center.
Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person unattended in a bathtub or shower.
It is recommended that lower water temperatures be used to avoid the risk of scalding. It is further recommended, in all cases, that the water temperature be set for the lowest temperature which satisfi es your hot water needs. This will also provide the most energy effi cient operation of the water heater.
NOTE: A water temperature range of 120°F-140°F (49°C-60°C) is recommended by most dishwasher manufacturers.
The thermostat of this water heater has been factory set at its lowest position (OFF). It is adjustable and must be reset to the desired temperature setting. The faceplate of the thermostat is marked with approximate temperature settings. The preferred starting point is approximately 120°F (49°C). Align the knob with the desired water temperature as shown in Figure 21. There is a hot water scald potential if the thermostat is set too high. Some states have a requirement for a lower setting.
Turn the water temperature dial clockwise ( the temperature, or counterclockwise (
) to increase
) to decrease the
temperature.
Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.

SERVICE AND ADJUSTMENT
Tank (Sediment) Cleaning
Sediment build-up on the tank bottom may create varying amount of noise, and if left in the tank will cause permanent tank failure. In some water areas, you may not be able to drain all sediment deposits by simply draining the tank. In these cases Mag-Erad (part no. 23600) can be used to help remove the sediment deposits. This may be ordered from the Sears Service Center. For ordering, refer to the Parts Order List section.
Vent System Inspection
• Flue gases may escape if vent pipe is not connected.
• Be alert for obstructed, sooted or deteriorated vent system to avoid serious injury or death.
• Do not store corrosive chemicals in vicinity of water heater.
Burner Inspection
Flood damage to a water heater may not be readily visible or immediately detectable. However, over a period of time a fl ooded water heater will create dangerous conditions
can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Contact a Sears Service Center to replace a fl ooded water heater. Do not attempt to
replaced!
At least once a year a visual inspection should be made of the main burner and pilot burner. See Figure 23.
You should check for sooting. Soot is not normal and will impair proper combustion.
Soot build-up indicates a problem that requires correction before further use. Turn “OFF” gas to water heater and leave off until repairs are made, because failure to correct the cause of the sooting can result in a fi re causing death, serious injury, or property damage.

which
• Chemical corrosion of fl ue and vent system can cause serious injury or death
At least once a year a visual inspection should be made of the venting system. You should look for:
• Obstructions which could cause improper venting. The combustion and ventilation air fl ow must not be obstructed.
• Damage or deterioration which could cause improper venting or leakage of combustion products.
• Rusted fl akes around top of water heater.
Be sure the vent piping is properly connected to prevent escape of dangerous fl ue gasses which could cause deadly asphyxiation.
Obstructions and deteriorated vent systems may present serious health risk or asphyxiation.
Chemical vapor corrosion of the fl ue and vent system may occur if air for combustion contains certain chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes, bleach and process chemicals are typical compounds which are potentially corrosive.
If when inspecting the vent system you find sooting or deterioration, something is wrong. Call the local gas supplier to correct the problem and clean or replace the fl ue and venting before resuming operation of the water heater.

Burner Cleaning
In the event your burner needs cleaning, following these instructions:
If inspection of the burner shows that cleaning is required, turn the gas control knob counter-clockwise ( depressing slightly.
The burner needs to be removed for cleaning. Call the Sears Service Center to remove and clean the burner and correct the problem that required the burner to be cleaned.

Page 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.
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 24.
INSTALLED IN SUITABLE AREA: To insure suffi cient 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 fl ammable liquids, etc. must not be placed against or adjacent to the water heater because they could catch on fi re.
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 deteriorates 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.
FIGURE 24.
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 the Sears Service Center for further information. Do not plug the temperature­pressure relief valve.
Draining
Anode deterioration depends on water conductivity, not 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 calling the Sears Service Center for an authorized contractor. At a minimum, the anode(s) should be checked annually after the warranty period.
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.
21

2. CLOSE the cold water inlet valve to the water heater.
4. Remove the washer and put the new one in place.
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.

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 fl ow 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 26.
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.

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 fl ame should still be drawn into the draft hood of the water heater with its burner fi ring. If the fl ame is not drawn toward the draft hood, shut off water heater and make necessary air supply changes to correct.
23
Page 24
Condensation
Whenever the water heater is fi lled 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:
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 new water heater is fi lled with cold water for the fi rst time.
• Burning gas produces water vapor In water heaters, particularly high effi ciency models where fl ue temperatures are lower.
• Large amounts of hot water are used in a short time and the refi ll 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 fl ue 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.
• 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
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 fi red 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 sulfi de gas dissolved in the water. The smell is
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 fl ammable 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 fl ame 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.

Operational Conditions (Continued)
Leakage Checkpoints
Read this manual fi rst. 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 fi lled with water. To prevent damage to the tank, the tank must be fi lled with water. Water must fl ow from the hot water faucet before turning “ON” gas to the water heater. See Figure 27.
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 fi tting 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 fi tting.
FIGURE 27.
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 fi tting.
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 fl oor. 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 fl oor 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 fi tting. If cotton is wet, follow “Draining” instructions in the Periodic Maintenance section and then remove fi tting. Put pipe dope or tefl on tape on the threads and replace. Then follow Filling the Water Heater instructions in the Installing the New Water Heater section.
