4. Attach a hose to the water heater drain valve and put the other end in a ﬂ oor drain or outdoors. (See Figures 2 and 5.) Open the water heater drain valve.

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

FIGURE 5.

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.

1. Turn “OFF” the gas supply to the water heater.

If the main gas line shutoff 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.

FIGURE 3.

2. Open a nearby hot water faucet until the water is no longer hot. When the water has cooled, turn “OFF” the water supply to the water heater at the water shut off valve or water meter. Some installations require that the water be turned off to the entire house. See Figures 2

FIGURE 4.

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 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.

FIGURE 7.

Page 10

Facts to Consider About the Location

Carefully choose an indoor location for the new water heater. 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 metal drain pan should be installed under the water heater. Metal 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 than 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 vapor 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 metal drain pan piped to a drain. Unanticipated damage can be reduced or prevented by a leak detector or water shut-off device used in conjunction with a piped metal 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 metal drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected.

• Sensors mounted in the metal drain pan that turn off the water supply to the entire home when water is detected in the metal 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 11

Minimum clearances between the water heater and combustible surfaces 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 8 inches (203 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.

• 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.

Page 12

• 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.

Combustion Air and Ventilation for Appliances Located in Unconﬁ ned Spaces

The conﬁ ned space shall be provided with two permanent

openings, one commencing within 12 inches (30 cm) of the top and one commencing within 12 inches (30 cm) from the bottom of the enclosure. The openings shall communicate directly, or by ducts, with the outdoors or spaces (crawl or attic) that freely communicate with the outdoors.

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.

• 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 (7.3 cm²/kW) of total input rating of all equipment in the enclosure. See Figure 13A.

FIGURE 13A.

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. Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the Temperature Regulation section in this manual.

• Louvers and Grilles: In calculating free area, consideration shall be given to the blocking effect of louvers, grilles or screens protecting openings. Screens used shall not be smaller than 1/4 inch (6.4 mm) mesh. If the free area through a design of louver or grille is known, it should be used in calculating the size opening required to provide the free area speciﬁ ed. 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.

This water heater shall not be connected to any heating systems or component(s) used with a non-potable water heating appliance.

Toxic chemicals, such as those used for boiler treatment, shall not be introduced into this system.

The water supply pressure should not exceed 80 psi. If this occurs, a pressure reducing valve with a bypass should be installed in the cold water inlet line. This should be placed on the supply to the entire house in order to maintain equal hot and cold water pressures.

In addition, the water within the water heater tank expands as it is heated, increasing 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.

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 = 1,035kPa) and a discharge capacity not less than the water heater input rate as shown on the model rating plate.

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 (15.3 cm) 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.

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 the temperature-pressure relief valve, and the discharge pipe.

• Shall terminate a maximum of six inches above a ﬂ oor drain or external to the building. In cold climates, it is recommended that the discharge pipe be terminated at an adequate drain inside the building.

• Shall terminate at an adequate drain.

• Shall not have any valve between the relief valve and tank.

Page 16

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.

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 inserting a ﬂ at head screwdriver in the slot on the stem and turn 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.

• Check all water piping and connections for leaks. Repair as needed.

of any vent damper, consult your local Sears Service Center or the local gas supplier for further information.

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 preexisting venting is used, the venting must be inspected for obstructions and if deterioration is present, it must be replaced.

IMPORTANT: Do not common vent this water heater with any power vented appliance.

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.

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

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 the legs to top with sheet metal screws. See Figure 17.

• 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.

Obstructed or deteriorated vent systems may present serious health risk or asphyxiation.

Page 17

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.

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.

Gas Piping

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 surface. Fill and seal any clearance between single wall vent pipe and combustible surfaces with mortar mix, cement, or other noncombustible substance. For other than single wall, follow vent pipe manufacturer’s clearance speciﬁ cations. To ensure a tight ﬁ t of the vent pipe in a brick chimney, seal around the vent pipe with mortar mix cement.

Failure to have required clearances between vent piping and combustible surfaces 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.

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. If the gas control valve 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.

There must be:

• A readily accessible manual shut off valve in the gas supply line serving the water heater.

• 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.

Page 18

Sediment Traps

Water heaters covered in this manual have been tested and approved for installation at elevations up to 2,000 feet (610 m) above sea level. For installation above 2,000 feet (610 m), 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 2,000 feet (610 m) 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 the National Fuel Gas Code, 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.

D. Do not use this appliance if any part has been under

water. Immediately call a qualified service technician to inspect the appliance. Water heaters subjected to flood conditions or anytime the gas controls, main burner or pilot have been submerged in water require replacement of the entire water heater.

E. DO NOT USE THIS APPLIANCE IF THERE HAS BEEN AN

IGNITION OF VAPORS. Immediately call a qualified service technician to inspect the appliance. Water heaters subjected to a flammable vapors ignition will show a discoloration on the air intake grid (bottom of combustion chamber) and require replacement of the entire water heater.

Press the gas control/temperature knob all the way in

and hold it in. The knob should travel in about 1/4 inch (6.35 mm) if it is set to "PILOT" correctly.

While holding the gas control/temperature knob in, click the igniter button continuously (about once a second) for up to 90 seconds or until Status Light begins to blink.

When the status light starts blinking, release the gas

control/temperature knob. Set the gas control/ temperature knob to the desired setting.

If the status light does not start blinking within 90 seconds, repeat steps 2 through 5 up to THREE (3) times, waiting 10 minutes between lighting attempts.

The circuitry in this advanced gas valve requires that you wait 10 minutes between lighting attempts.

If the status light turns solid red, release the gas control/temperature knob and repeat steps 2 through 5 (waiting 10 minutes before attempting to relight the pilot).

If the status light does not start blinking after three lighting attempts, turn the gas control/temperature knob to "OFF" and call a qualified service technician or your gas supplier.

TO TURN OFF GAS TO APPLIANCE

1. Turn the gas control/temperature knob counterclockwise to the "OFF" setting. The status light will stop blinking and stay on for a short time after the water heater is turned off.

Pilot

Page 20

Temperature Regulation

The thermostat is adjusted to the pilot position when it is shipped from the factory. Water temperature can be regulated by moving the temperature dial to the preferred setting. The preferred starting point is 120°F at the “HOT” setting. Align the knob with the desired water temperature as shown in Figure 22. There is a hot water scald potential if the thermostat is set too high. NOTE: Temperatures shown on the gas control valve/ thermostat are approximates. The actual temperature of the heated water may vary.

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.

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.

NOTE: A water temperature range of 120°F-140°F (49°C-60°C) is recommended by most dishwasher manufacturers.

IMPORTANT: Adjusting the thermostat past the 120°F bar on the temperature dial will increase the risk of scald injury. Hot water can produce first degree burns within:

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.

NOTE: 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 temperature dial to the vacation (VAC) setting. This will maintain the water at low temperatures with minimum energy losses and prevent the tank from freezing during cold weather.

Operating the Temperature Control System

Water Temperature Adjustment

The water temperature setting can be adjusted from 55°F to 155°F. Turn the Gas Control/Temperature Knob to the desired setting/temperature. See Figure 22 on page 20.

NOTE: The temperatures indicated are approximates. The actual temperature of the heated water may vary.

Operating Modes and Settings

• Standard Mode - The controller adjusts the water heater

to maintain the temperature set by the user.

• Vacation Setting - The Vacation Setting (VAC) sets

the controller at approximately 55°F. This setting is recommended when the water heater is not in use for a long period of time. This effectively turns the controller temperature setting down to a temperature that prevents the water in the water heater from freezing while still conserving energy.

SERVICE AND ADJUSTMENT

Vent System Inspection

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.

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 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 which 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 repair the unit! It must be replaced!

At least once a year, a visual inspection should be made of the main burner. See Figure 23.

Removing and Replacing the Gas Control Valve/Thermostat

Removing the Gas Control Valve/Thermostat:

1. Turn the gas control/temperature knob to the “OFF” position (Figure 22).

2. Turn off the gas at the manual shut-off valve on the gas supply pipe (Figure 2).

3. Drain the water heater. Refer to the section on “Draining and Flushing” and follow the procedure.

4. Disconnect the igniter wire from the igniter lead wire. Disconnect the temperature sensor wire, then use needle nose pliers to disconnect the red (+) and white (-) thermopile wires. Disconnect the pilot tube (7/16” wrench) and manifold tube (3/4” wrench) at the gas control valve/ thermostat (Figure 25).

5. Refer to “Gas Piping” (Figure 2) and disconnect the ground joint union in the gas piping. Disconnect the remaining pipe from the gas control valve/thermostat.

6. To remove the gas control valve/thermostat, thread a 4-inch section of gas pipe into the inlet and use it to turn the gas control valve/thermostat (counterclockwise.) Do not use a pipe wrench or equivalent to grip body. Damage may result. Do not insert any sharp objects into the inlet or outlet connections. Damage to the gas control valve/ thermostat may result.

Replacing the Gas Control Valve/Thermostat:

To replace the gas control valve/thermostat, reassemble in reverse order. When replacing the gas control valve/thermostat, thread a 4-inch section of gas pipe into the inlet and use it to turn the gas control valve/thermostat (clockwise.) DO NOT OVER TIGHTEN. Damage may result.

• Be sure to use approved Teflon® tape or pipe joint compound on the gas piping connections and fitting on the back of the gas control valve that screws into tank.

• Be sure to remove the pilot ferrule nut from the new gas control valve/thermostat.

• Turn the gas supply on and check for leaks. Test the water heater by brushing on an approved noncorrosive leak detection solution. Bubbles forming indicate a leak. Correct any leak found.

• Be sure tank is completely filled with water before lighting and activating the water heater. Follow the “Lighting Instructions” in the “Operating Instructions” section.

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 FLAME ARRESTOR. CLEAN IF LINT ACCUMULATIONS ARE NOTICED.

INSTALLED IN SUITABLE AREA: To ensure 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.

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. The anode rod should be checked after a maximum of three years of use, then annually until the condition of the anode rod dictates the replacement of it. NOTE: Artiﬁ cially softened water requires the anode rod to be inspected annually.

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 33.

FIGURE 33.

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

It is recommended that the tank be drained and ﬂ ushed every 6 months to remove sediment which may build up during operation. The water heater should be drained if being shut down during freezing temperatures. To drain the tank, perform the following steps:

Turn off the gas to the water heater at the manual gas 1. shut-off valve.

Open a nearby hot water faucet until the water is no longer hot.2.

Close the cold water inlet valve.3.

Connect a hose to the drain valve and terminate it to an 4.

adequate drain or external to the building.

Open the water heater drain valve and allow all of the water 5.

to drain from the tank. Flush the tank with water as needed to remove sediment.

Close the drain valve, reﬁ ll the tank, and restart the heater 6.

as directed in this manual.

If the water heater is going to be shut down for an extended period, the drain valve should be left open.

IMPORTANT: Condensation may occur when reﬁ lling the tank and should not be confused with a tank leak.

Follow the lighting instructions in the Lighting section to restart the water heater.

TROUBLESHOOTING GUIDE

Start Up Conditions

Thermal Expansion

As water is heated, it expands (thermal expansion). In a closed system, the volume of water will grow. As the volume of water grows, there will be a corresponding increase in water pressure due to thermal expansion. Thermal expansion can cause premature tank failure (leakage). This type of failure is not covered under the limited warranty. Thermal expansion can also cause intermittent temperature-pressure relief valve operation: water discharged from the valve due to excessive pressure build up. The temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This condition is not covered under the limited warranty.

A properly-sized thermal expansion tank should be installed on all closed systems to control the harmful effects of thermal expansion. Contact a plumbing service agency or your retail supplier regarding the installation of a thermal expansion tank.

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

WARNING

Burn Hazard

Do not touch vent.

Doing so can result in burns.

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 after 15 minutes of burner operation, shut off water heater and make necessary air supply changes to correct.

Page 29

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:

• 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.

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.

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.

Water Temperature 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 burner and can result in increased water temperatures at the hot water outlet.

This water heater’s temperature control has been designed to accurately regulate the water temperature. However, under certain operating conditions, the water temperature may temporarily exceed the dial setting. Consequently, in addition to setting the temperature no higher than 120°F, we recommend the installation of a mixing valve or an anti-scald device in the hot water supply line or at the point of use to further reduce the risk of scald injury. These devices can be obtained from a plumbing service agency or your retail supplier.

“AIR” In Hot Water Faucets

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 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

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.

Safety Shut-Off

This water heater is equipped with an automatic gas shutoff system. This system works when high water temperatures are present. 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. Turn “OFF” the entire gas supply to the water heater and contact your gas supplier.

This water heater is designed to automatically shut-off in the event of the following:

1. The pilot flame is extinguished for any reason.

Page 30

2. The water temperature exceeds 189°F (87°C).

6” MAXIMUM AIR GAP

A C

3. Excessive contaminants in the combustion chamber.

4. The ignition of flammable vapors.

A thermopile is used to determine if a pilot ﬂ ame is present and will shut off the gas supply to the main burner and pilot if the ﬂ ame is absent. This unit is also equipped with a combustion chamber temperature sensor. This sensor will shut off the gas supply to the burner if lint, dust, or other contaminants pollute the burner. If the gas control valve/thermostat shuts off the gas supply, check the diagnostic ﬂ ash code and refer to the “Status Light Troubleshooting Chart.” If necessary, also refer to the “Troubleshooting Guide.”

Also, a temperature limit switch or ECO (Energy Cut Off) sensor located in the gas control valve\thermostat is used to shut off the water heater if the water temperature exceeds 189°F (87°C). The Diagnostic Status Light will flash a code indicating an “Overheat Failure” (4 Flashes). See “Operating the Temperature Control System.” If the ECO has functioned, the gas control valve/thermostat should be replaced by a qualified technician. Contact Sears Service for service information.

If the Diagnostic Status Light indicates an “LDO Occurrence” (10 Flashes), refer to the “Status Light Troubleshooting Chart.”

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.

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 a qualiﬁ ed technician.

Leakage Checkpoints

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.

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.

FIGURE 36.

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 “Draining” section and then remove ﬁ tting. Put pipe dope or teﬂ on tape on the threads and replace. When you are ﬁ nished, follow the steps in “Filling the Water Heater” in the Installation Instructions earlier in this manual.
