INSTALLATION INSTRUCTIONS

Removing the Old Water Heater

FIGURE 2.

4. Attach a hose to the water heater

drain valve and put the other end in a 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 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 shutoff valve

se r v i ng all gas appli a n c es 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 shut

off 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.

FIGURE 7.

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 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 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 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 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 ammable vapors which can be ignited by a gas water heater’s pilot light or main burner. The resulting ashback and re can cause death or serious burns to anyone in the area. Even though this water heater is a ammable vapors ignition resistant water heater and is designed to reduce the chances of ammable vapors being ignited, gasoline and other ammable substances should never be stored or used in the same vicinity or area containing a gas water heater or other open 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 oor must be covered by the panel. Failure to heed this warning may result in a re hazard.

FIGURE 9.

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.

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 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 conned area such as a closet, unless you provide air as shown in the Locating The New Water Heater section. Never obstruct the 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 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 identication of components mentioned below). Failure to follow these instructions can restrict the air ow required for proper combustion, potentially resulting in 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 oor

•

to prevent blockage of combustion air 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 ow.

Combustion Air and Ventilation for

AppliancesLocatedinUnconnedSpaces

UNCONFINED SPACE is space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kW) of the 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 unconned space.

In unconned spaces in buildings, inltration may be adequate to provide air for combustion, ventilation and dilution of 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 Conned Spaces.

Combustion Air and Ventilation for

AppliancesLocatedinConnedSpaces

The con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.

FIGURE 11.

CONFINED SPACE is a space whose volume is less than

50 cubic feet per 1,000 Btu per hour (4.8 m3 per kW) of the aggregate input rating of all appliances installed in that space.

A. ALL AIR FROM INSIDE BUILDINGS:

(See Figure 9 on page 9 and Figure 10 below)

The conned space shall be provided with two permanent

openings communicating directly with an additional room(s) of sufcient volume so that the combined volume of all spaces meets the criteria for an unconned space. The total input of all gas utilization equipment installed in the combined space shall be considered in making this determination. Each opening shall have a minimum free area of one square inch per 1,000 Btu per hour (22 cm2/kW) of the total input rating of all gas utilization equipment in the conned space, but not less than 100 square inches (645 cm2). One opening shall commence within 12 inches (30 cm) of the top and one commencing within 12 inches (30 cm) of the bottom of the enclosures.

• When directly communicating with the outdoors, each opening shall have a minimum free area of 1 square inch per 4,000 Btu per hour (5.5 cm2/kW) of total input rating of all equipment

in the enclosure. See Figure 12.

• When communicating with the outdoors through vertical ducts, each opening shall have a minimum free area of 1 square inch per 4,000 BTU per hour (5.5 cm2/kW) of total input rating of all equipment in the enclosure. See Figure 12.

FIGURE 10.

B. ALL AIR FROM OUTDOORS: (See Figures 9, 11,12 and 13)

FIGURE 12.

• When communicating with the outdoors through horizontal ducts, each opening shall have a minimum free area of 1 square inch per 2,000 BTU per hour (11 cm2/kW) of total input rating of all equipment in the enclosure. See Figure 13.

• When ducts are used, they shall be of the same cross-sectional area as the free area of the openings to which they connect.

The minimum short side dimension of rectangular air ducts

shall not be less than 3 inches (76.2 mm). See Figure 13.

FIGURE 13.

• 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 14.

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 inrm, or physically/mentally handicapped. If anyone using hot water in your home 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 satis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 15. 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.

FIGURE 14.

• 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 speci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 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 replaces may create conditions requiring special attention to avoid unsatisfactory operation of installed gas utilization equipment.

FIGURE 15.

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 have installed devices such as pressure reducing valves, check valves, back 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 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.

• Look at the top of the water heater. The cold water inlet is marked “COLD”. Put two or three turns of Teon tape around the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4” NPT threaded nipple. Using 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

NOTE: To protect against untimely corrosion of hot and cold

waterttings, it isstronglyrecommended that di-electric

unions or couplings be installed on this water heater when connected to copper pipe.

Figure 16 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 befo re att aching the ad apter to the cold water inlet connection. Do not solder the cold water supply line directly 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 Teon tape around the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4” NPT threaded nipple. Using exible connectors, connect the hot water pipe to the hot water outlet

on the water heater.

Temperature-Pressure Relief Valve

FIGURE 17.

This heater is provided with a properly certied combination temperature - pressure relief valve by the manufacturer.

The valve is certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment as meeting the requirements for Relief Valves and 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 certi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 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 oor, see Figure 17. 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.

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 at an adequate drain or external to the structure.

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

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 ow may cause property damage.

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 lled with water. Water must ow from the hot water faucet before turning “ON”

gas to the water heater.

To 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 insure complete lling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant ow is obtained. This will let air out of the water heater and the piping.

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.

To insure proper venting of this gas-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 ow must not be obstructed.

• 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-red water heaters having thermal efciency in excess of 80% may produce a relatively low ue gas temperature. Such temperatures may not be high enough to properly open thermally operated vent dampers. This would cause spillage of the ue gases and may cause carbon monoxide poisoning.

Vent dampers must bear evidence of certication as complying

with the current edition of the American National Standard

ANSI Z21.68 (ANSI Z21.66 & 67, respectively, cover electrically

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 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 18.

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

FIGURE 18.

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 19.

Be sure vent pipe is properly connected to prevent escape of dangerous ue gases which could cause deadly asphyxiation.

Chemical vapor corrosion of the 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 19.

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 specications. To insure a tight t of the vent pipe in a brick chimney, seal around the vent pipe with mortar mix cement.

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 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 suf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, 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.

Failure to have required clearances between vent piping and combustible material will result in a re hazard.

• A 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 ame. Rinse off soapy solution and wipe dry.

The minimum inlet gas pressure shown on the rating plate is that which will permit ring at the rated input.

Sediment Traps

Water heaters covered in this manual have been tested and approved for installation at elevations up to 7,700 feet (2,347m) 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 orice in accordance with the current edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54. Contact your local gas supplier for further information.

Failure to replace the standard orice with the proper high altitude orice when installed at elevations above 7,700 feet (2,347m) could result in improper and inef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 speci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 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 tting with a capped nipple in the bottom outlet or other device recognized as an effective sediment trap. If a tee tting is used, it shall be installed in conformance with one of the methods of installation, shown in

Figures 19 and 20.

Use pipe joint compound or Teon tape marked as being resistant to the action of petroleum (Propane [L.P.]) gases.

The appliance and its gas connection must be leak tested before placing the appliance in operation.

The applia nce and its individ ual shu toff 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 (3.5 kPa). 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 (3.5 kPa).

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 20 and 21.

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 inrm, or physically/mentally handicapped. If anyone using hot water in your home 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 satis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 thermostat setting, see Figures 22 and 23. Using the lowest hot water temperature that meets your needs will also provide the most energy efcient operation of the water heater.

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.

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 (PILOT LIGHTING). It is adjustable and must be reset to the desired temperature setting to reduce the risk of scald injury. The mark ( ) indicative of approximately 120°F (49°C) is preferred starting point. Some states have a requirement for

a lower setting.

Turn the water temperature dial clockwise ( ) to decrease the temperature, or counterclockwise ( ) to increase 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

Burner Inspection

Flood damage to a water heater may not be readily visible or immediately detectable. However, over a period of time a 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 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 and pilot burner. See Figure 24.

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 re causing death, serious injury, or property damage.

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 ow must not be obstructed.

• Damage or deterioration which could cause improper venting or leakage of combustion products.

• Rusted akes around top of water heater.

Be sure the vent piping is properly connected to prevent escape of dangerous ue gasses which could cause deadly asphyxiation.

Obstructions and deteriorated vent systems may present serious health risk or asphyxiation.

If when ins pecting the ven t syste m you find sooting or deterioration, something is wrong. Call the local gas supplier to correct the problem and clean or replace the ue and venting before resuming operation of the water heater.

FIGURE 24.

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 clockwise ( ) to the “OFF” position, depressing slightly.

NOTE: The knob cannot be turned from “PILOT” to “OFF” unless knob is depressed slightly. DO NOT FORCE.

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.

Housekeeping

Vacuum around base of water heater for dust, dirt, and lint on a regular basis.

AT LEAST ONCE EVERY SIX MONTHS A VISUAL INSPECTION SHOULD BE MADE OF THE AIR INTAKE SCREEN. CLEAN IF LINT ACCUMULATIONS ARE NOTICED.

INSTALLED IN SUITABLE AREA: To insure suf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 ammable liquids, etc. must not be placed against or adjacent to the water heater because they could catch on re.

rod, check for any leaks and immediately correct if found. In situations where clearance above the water heater is limited it may be necessary to bend the anode rod for removal. Flexible anode rods are available for replacement.

In replacing the anode:

1. Turn off gas supply to the water heater.

2. Shut off the water supply and open a nearby hot water faucet to depressurize the water tank.

3. Drain approximately 5 gallons of water from tank (Refer to the “Draining and Flushing” section for proper procedures). Close drain valve.

4. Remove old anode rod.

5. Use Teon® tape or approved pipe sealant on threads and

install new anode rod.

6. Turn on water supply and open nearby hot water faucet to purge air from water system. Check for any leaks and

immediately correct any if found.

7. Restart the water heater as directed under the “Operating Your Water Heater” section. See the “Repair Parts Illustration”

section for anode rod location.

Temperature-Pressure Relief Valve Operation

The temperature-pressure relief valve must be manually operated

at least once a year.

Anode Rod

Each heater contains at least one anode rod, which will slowly deplete while protecting the glass-lined tank from co rrosi o n and pr o longi ng the li fe of th e water heater. Once the anode is depleted, the tank will start to corrode, eventually developing a leak. The use of a water softener may decrease the life of the water heater tank. The anode rod should be removed from the water heater tank every 3 years for inspection. The following are typical (but not all) signs of a depleted anode rod:

• The majority of the rod’s diameter is less than 3/8”.

• Signicant sections of the support wire (approx. 1/3 or more of the anode rod’s length) are visible.

If the anode rod shows signs of either or both it should be replaced. NOTE: Whether re-installing or replacing the anode

When checking the temperature-pressure relief valve operation, make sure that (1) no one is in front of or around the outlet of the temperature-pressure relief valve discharge line, and (2) that the water discharge will not cause any property damage, as the water may be extremely hot, see Figure 25.

FIGURE 25.

If 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.

Drain Valve Washer Replacement

(See Figure 26)

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

Draining

The water heater should be drained if being shut down during freezing temperatures. Also periodic draining and cleaning of sediment from the tank may be necessary.

1. Turn the gas control knob to the “OFF” position.

2. CLOSE the cold water inlet valve to the water heater.

3. OPEN a nearby hot water faucet and leave open to allow for

TROUBLESHOOTING GUIDE

Start Up Conditions

Thermal Expansion

Water supply system may, because of such events as high line pressure, frequent cut-offs and the effects of water hammer have installed devices such as pressure reducing valves, check valves, back 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.

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.

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,

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 ame should still be drawn into the draft hood of the water heater with its burner ring. If the ame is not drawn toward the draft hood, shut off water heater and make necessary air supply changes to correct.

Condensation

• a concentration of sulfate in the supply water.

Whenever the water heater is 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 lled with cold water for the rst time.

• Burn ing gas pr oduces water vapor In water heate rs, particularly high efciency models where ue temperatures

are lower.

• Large amounts of hot water are used in a short time and the

re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 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.

• little or no dissolved oxygen in the water.

• a sulfate reducing bacteria within the water heater. (This harmless bacteria is non-toxic to humans.)

• an excess of active hydrogen in the tank. This is caused by the corrosion protective action of the anode.

Smelly water may be eliminated or reduced in some water heater models by replacing the anode(s) with one of less active material, and then chlorinating the water heater tank and all hot water lines. Contact Sears Service for further information concerning an Anode Replacement Kit #9001453 and this Chlorination Treatment. Anode replacement and chlorination of the tank are not covered by the water heater’s limited warranty.

If the smelly water persists after the anode replacement and chlorination treatment, it may be necessary to chlorinate or aerate your water supply to eliminate the problem.

Do not remove the anode leaving the tank unprotected. By doing so, all warranty on the water heater tank is voided.

“AIR” In Hot Water Faucets

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 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 sulde gas dissolved in the water. The smell is the result of four factors which must all be present for the odor to develop:

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 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 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 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 lled with water. To prevent damage to the tank, the tank must be lled with water. Water must ow from the hot water faucet before turning “ON” gas to the water heater, see Figure 28.

A. Water at the draft hood is water vapor which has condensed

out of the combustion products. This is caused by a problem in the vent. Contact the gas utility.

B. *Condensation may be seen on pipes in humid weather or

pipe connections may be leaking.

C. *The anode rod 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 tting.

FIGURE 28.

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 tting.

H. Co mbust ion 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 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 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 tting. If cotton is wet, follow

“Draining” instructions in the Periodic Maintenance section

and then remove tting. Put pipe dope or Teon tape on the threads and replace. Then follow Filling the Water Heater

instructions in the Installing the New Water Heater section.
