INSTRUCTIONS FOR INSTALLATION

Removing the Old Water Heater

FIGURE 1.

4. Attach a hose to the water heater drain valve and put the other end in a floor 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 flow is directed away from any person, see Figures 1 and 4.

5. Disconnect the vent pipe from the draft hood where they connect 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 the 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. This will avoid cutting off pipes too short. Additional cuts can be made later if necessary. Disconnect the temperaturepressure 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, see Figure 5.

FIGURE 4.

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

If the main gas line Shut-off valve serving all gas appliances is used, also shut “OFF” the gas at each appliance. Leave all gas appliances shut “OFF” until the water heater installation is completed, see Figures 1 and 2.

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 1 and 3.

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 2.

FIGURE 3.

FIGURE 5.

If you have galvanized pipe 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 . 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, see Figure 6.

more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/ mentally handicapped. If anyone using hot water in your home fits 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 satisfies your hot water needs, a means such as a *Mixing Valve, shall 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 8. Valves for reducing point of use temperature by mixing cold and hot water are also available. Consult Maytag Customer Service (1-800-788-8899). Follow mixing valve manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual, see Figure 52 on page 31.

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

Toxic chemicals such as used for treatment of boilers or nonpotable water heating appliances shall never be introduced into a potable water space heating system.

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

NOTE: T o protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that di-electric unions or couplings be installed on the water heater when connected to copper pipe.

LOCATING THE NEW WATER HEATER

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:

• The location selected should be indoors as close as practical to the vent termination point, and as centralized with the water piping system as possible. The water heater, as all water heaters, will eventually leak. Do not install without adequate drainage provisions where water flow will cause damage.

• 40,000 BTU/HR INPUT MODELS - If vented through an outside wall or through the roof, the 3” vent piping cannot exceed a total of 115 feet (50 feet if optional 2” vent piping is used), including vertical and horizontal runs with one 90 are required, the venting distance must be reduced 5 feet for every 90 elbow, see p age 22 for vent chart.

• 70,000 and 75,000 BTU/HR INPUT MODELS -If vented through an outside wall or through the roof, the 3” vent piping cannot exceed a total of 70 feet (110 feet if optional 4” vent piping is used), including vertical and horizontal runs with one 90 If more elbows are required, the venting distance must be reduced 5 feet fro every 90 elbow, see p age 22 for vent chart.

• Vent piping cannot slope downward and horizontal runs require 1/8” per five foot rise. All horizontal runs require adequate support at 3 1/2 foot intervals and vertical runs supported at 5 foot intervals.

elbow. If more elbows

elbow.

Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor. 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 flow.

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.

• Devices that will turn off the gas supply to a gas water heater while at the same time shutting off its water supply.

• The water heater requires its own (separate) venting system. It cannot be connected to an existing vent pipe or chimney. It must terminate to the outdoors. Whenever possible terminate the vent on the leeward side of the building if vented through an outside wall. NOTE: Condensation may be created, at times,

as the combustion gases exit the vent cap and discoloration of surfaces in proximity to the vent cap may occur.

The power vent water heater requires its own (separate) venting system. It cannot be connected to an existing vent pipe or chimney. It must be terminated to the out doors. Failure to properly install the venting system can result in asphyxiation, a fire or explosion and can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.

• The water heater comes equipped with a 7 foot power cord which can be used to connect to a 110/120 volt power source if (1) local codes allow, and (2) there is a three prong recept acle available. This unit must have a grounded outlet to operate.

Do not use an extension cord. If there is not a suitable receptacle and/or local codes prohibit use of a power cord, field wiring must be provided.

Page 11

INST ALLA TIONS 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 flammable vapors which can be ignited by a gas water heater’s pilot light or main burner. The resulting flashback and fire can cause death or serious burns to anyone in the area, as well as property damage. If installation in such areas is your only option, then installation must be accomplished in a way that the pilot flame and main burner flame are elevated from the floor at least 18 inches. While this may reduce the chances of flammable vapors, from a floor spill being ignited, gasoline and other flammable substances should never be stored or used in the same room or area containing a gas water heater or other open flame or spark producing appliance. NOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.

Also, the water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle.

Propellants of aerosol sprays and volatile compounds, (cleaners, chlorine based chemicals, refrigerants, etc.) in addition to being highly flammable 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.

FIGURE 9.

• Do not obstruct water heater air intake with insulating blanket.

• Gas and carbon monoxide detectors are available.

• Install water heater in accordance with the instruction manual.

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 (76.2 mm) in any direction, or if the appliance is installed in an alcove or closet, the entire floor must be covered by the panel. Failure to heed this warning may result in a fire hazard.

A gas water heater cannot operate properly without the correct amount of air for combustion. Do not install in a confined area such as a closet, unless you provide air as shown in the Locating The New Water Heater section. Never obstruct the flow of ventilation air. If you have any doubt s or questions at all, call your gas supplier. Failure to provide the proper amount of combustion air can result in a fire or explosion and cause death, serious bodily injury, or property damage.

FIGURE 10.

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 from outside these areas.

Minimum clearances between the water heater and combustible construction are 0 inch at the sides and rear, 6 inches (152 mm) at the front, and 0 inches from the vent pipe. Clearance from the top of the jacket is 14 inches (356 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, see Figure 9.

• Install water heater in accordance with the instruction manual and NFPA 54.

• To avoid injury, combustion and ventilation air must be taken from outdoors.

• Do not place chemical vapor emitting products near water heater.

Insulation blankets available to the general public for external use on gas water heaters are not necessary with Maytag products. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Your Maytag 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.

Should you choose to apply an insulation blanket to this heater, you should follow these instructions (See Figure 7 for identification of components mentioned below). Failure to follow these instructions can restrict the air flow required for proper combustion, potentially resulting in fire, asphyxiation, serious personal injury or death.

UNCONFINED SP ACE is space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m

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 unconfined space.

In unconfined spaces in buildings, infiltration may be adequate to provide air for combustion, ventilation and dilution of flue 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 Confined Spaces.

Combustion Air and V entilation for Appliances Located in Confined Spaces

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.

FIGURE 20.

• 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 specified. 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 fixed 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 fireplaces may create conditions requiring special attention to avoid unsatisfactory operation of installed gas utilization equipment.

HOTTER WA TER 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 infirm, or physically/mentally handicapped. If anyone using hot water in your home fits 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

Page 15

addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a *mixing valve, shall 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 8 on page 9 and Figure 21 below. V alves for reducing point of use temperature by mixing cold and hot water are also available. Consult Maytag

Customer Service (1-800-788-8899). 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.

See Figure 21 for mixing valve usage.

Figure 22 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 3/4” NPT water connections for 40,000 Btuh models and 1 inch water connections for 70,000 and 75,000 Btuh models.

NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the cold water inlet connection. Do not solder the cold water supply line directly 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”. Connect the hot water pipe to the hot water outlet on the water heater.

• Look at the top of the water heater. The cold water inlet is marked “COLD”. 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.

FIGURE 21.

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

If a water heater installed in a closed water supply system; such as one having a back-flow preventer, check valve, water meter with a check valve, etc. . . in the cold water supply; means shall be provided to control thermal expansion. Contact the local utility or call Maytag Customer Service Center at

1-800-788-8899 for an authorized installer on how to control this situation.

NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that di-electric unions or couplings be installed on this water heater when connected to copper pipe.

FIGURE 23.

T emperature-Pressure Relief Valve

• Temperature-pressure relief valve must comply with ANSI Z21.22 and ASME code.

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, see Figure 24.

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 flow may cause property damage.

• Properly sized temperature-relief valve must be installed in opening provided.

• Can result in overheating and excessive tank pressure.

• Can cause serious injury or death.

This heater is provided with a properly certified 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 of materials as meeting the requirements for Relief V alves and Automatic Gas Shut-off Devices for Hot W ater 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 certified as indicated in the above paragraph.

The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 psi = 1,035 kPa) and a discharge capacity not less than the water heater input rate as shown on the model rating plate.

FIGURE 24.

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.

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 fitting 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 floor. Be certain that no cont act is made with any live electrical part. The discharge opening

• 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.

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

Page 17

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 temperature-pressure 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.

Wiring

USE WITH POWER CORD

The water heater comes equipped with a 7 foot power cord which can be used to connect to a 110/120 volt power source if, (1) local codes allow, and (2) there is a three prong grounded receptacle available. This unit must have a grounded outlet to

operate.

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 filled with water. W ater must flow from the hot water faucet before turning “ON” gas to the water heater.

To fill 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.

FIGURE 25.

You must provide all wiring, (1) to a receptacle or, (2) between the water heater and junction box when power cord is not used.

Do not use an extension cord. If there is not a suitable receptacle and/or local codes prohibit use of a power cord, field wiring must be provided.

If you are not familiar with electric codes and practices, or if you have any doubt in your ability to connect the wiring to this water heater, obtain the service of a competent electrician or contact your local electric utility.

NOTE: The cold water supply valve must be left open when the water heater is in use.

• To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant flow 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.

If wiring from the fuse box or circuit breaker box was aluminum for the old water heater, replace it with copper wire. If you wish to reuse the existing aluminum wire, have the connection at the water heater made by competent electrician. Contact a local electrical contractor and/or the local electric utility.

Page 18

USE WITHOUT POWER CORD

If power cord cannot be used, then follow these wiring instructions.

• Provide a way to easily shut off the electric power when working on the water heater. This could be with a circuit breaker or fuse block in the entrance box or a separate disconnect switch.

• Install and connect a circuit directly from the main fuse or circuit breaker box. This circuit must be the right size and have its own fuse or circuit breaker.

A standard 1/2” conduit opening has been made in the water heater junction box for the conduit connection.

• Use wire nuts and connect the power supply wiring to the wires inside the water heater’s junction box.

• The water heater must be electrically “grounded” by the installer. The unit will not operate unless it is properly grounded. A green ground screw has been provided on the water heater’s junction box. Connect ground wire to this location. For complete grounding details and all allowable exceptions, refer to the current edition of the National Electrical Code, ANSI/NFPA 70.

After reading the manual and you have determined the location of the opening in the wall, (using the drawing below), cut a 2 1/2” hole for 2” vent piping, 3 1/2” hole for 3” vent piping or a 4 1/2” hole for 4” vent piping through an exterior wall.

NOTE: When determining location of the opening in the outside wall allow for the 1/8” rise per five feet that has taken place in the horizontal run.

Page 24

FIGURE 42.

FIGURE 44.

• If there is to be a vertical run of vent from blower, the 3” PVC, ABS or CPVC pipe must be attached to the blower using 3 sheet metal screws.

The 3” )or optional 2” or 4”) PVC, ABS or CPVC Schedule 40 vent pipe can be run from the water heater through the wall or from the wall to the water heater, whichever is most convenient. The vent pipe must extend a minimum of 1 1/2” through the exterior wall. Extending the vent cap as far as possible from the surface of the exterior wall will help minimize discoloration of the wall in this area which may be caused by the flue gases.

NOTE: that the inside collar must be slipped over the vent piping before locating the pipe through the wall. Before securing the inside and outside collars to the wall, use a silicone sealer between pipe and opening to insure a water and air tight seal.

Gas Piping

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

If a standard model is installed above 3,300 feet (1,006 m) or a high altitude model is installed above 5,500 feet (1,676 m) the input rating 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 orifice in accordance with National Fuel Gas Code ANSI Z223.1/NFPA 54. Contact Maytag Customer Service

Center at 1-800-788-8899 or your local gas supplier or call for further information.

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 (2.6kPa) for natural and propane (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 fire or explosion from leaking gas.

If the main gas line Shut-off 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 sufficient 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.

• A flexible gas connector or a ground joint union between the shut off valve and control valve to permit servicing of the unit.

Failure to replace the standard orifice with a high altitude orifice when installed at elevations above 3,300 feet (1,006 m) or above 5,500 feet (1,676 m) for high altitude model could result in improper and inefficient operation of the appliance, producing carbon monoxide gas in excess of safe limits, which could result in serious injury or death. Contact Maytag Customer

Service at 1-800-788-8899 or your local gas supplier for any specific changes which may be required in your area.

Use pipe joint compound or teflon 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 appliance and its individual Shut-off valve shall be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 pound per square inch (3.5kPa). It shall be isolated from the gas supply piping system by closing its individual manual Shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 pound per square inch (3.5kPa).

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 flame. Rinse off soapy solution and wipe dry.

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 49 and 50.

Page 27

Sediment Traps

• Contaminants in gas lines can cause fire or explosion.

• Clean all gas piping before installation.

• Install drip leg in accordance with NFP A 54.

Contaminants in the gas lines may cause improper operation

of the gas control valve that may result in fire or explosion. Before attaching the gas line be sure that all gas pipe is clean on the inside. To trap any dirt or foreign material in the gas supply line, a drip leg (sometimes called a sediment trap) must be incorporated in the piping. The drip leg must be readily accessible. Install in accordance with the Gas Piping section. Refer to the current edition of th

e 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 fitting with a capped nipple in the bottom outlet or other device recognized as an effective sediment trap. If a tee fitting is used, it shall be installed in conformance with one of the methods of installation, shown in Figures 49 and 50.

OPERATING INSTRUCTIONS

This water heater is equipped with an electronically operated venting system and electronic control. For the burner to come on, the water heater thermostat must call for heat. Then the system will begin sequencing, each section proving itself before gas is allowed to flow to the burner.

BEFORE THE WA TER HEA TER WILL OPERA TE:

1. The control system must be connected to a grounded 110/ 120 volt power supply. The control system has an overall rating of 2 amps. The water heater must be securely and adequately grounded in accordance with local codes and with the current edition of the National Electrical Code ANSI/ NFPA 70.

2. The ON/OFF rocker switch, located on the control box above the thermostat must be in the “ON” position for the electrical control system to operate allowing the gas portion to operate (ignite burner).

3. The venting manual reset switch must be in the closed position. See “Venting Manual Reset Switch” in the “Troubleshooting” section.

4. There is a non-resettable hi-limit switch in the thermostat, which must be good (closed) for the thermostat to be operated. See “High Temperature Limit Switch” in the “Troubleshooting” section.

OPERATION

When the thermostat calls for heat, gas is allowed to flow to a (N/O) pressure switch closing it. An electrical circuit is then made to the blower, turning it on. When the blower has achieved sufficient venting, the air pressure switch will close. A 120 volt circuit will be completed through the venting manual reset switch and on the 120 volt gas valve. The 120 volt gas valve will open allowing gas to flow to the burner. The hot surface ignitor will establish a main burner flame.

FIGURE 51.

Page 29

Operating

Propane gas is heavier than air. Should there be a leak in the

system, the gas will settle near the ground. Basements, crawl spaces, skirted areas under manufactured (mobile) homes (even when ventilated), closets and areas below ground level will serve as pockets for the accumulated gas in the area. Search for odor of gas by sniffing at ground level in the vicinity of the appliance. If odor is detected, follow steps indicated at “For Your Safety” on the cover of this manual then leave the premises.

Operating instructions are located on front of the water heater, above or to the side of the gas control valve, see page 30.

CHECK FOR LEAKS

Be sure to check all your gas pipes for leaks before operating your water heater. Use a soapy water solution, not a match or open flame. Check the factory gas fittings when the main burner is turned “ON”.

Temperature Regulation

Short repeated heating cycles caused by small hot water uses can cause temperatures at the point of use to exceed the thermostat by up to 30oF. If you experience this type of use you should consider using lower temperature settings to reduce scald hazards.

Any water heater’s intended purpose is to heat water. Hot water is needed for cleansing, cleaning, and sanitizing (bodies, dishes, clothing). Untempered hot water can present a scald hazard. Depending on the time element, and the people involved (adults, children, elderly , infirm, etc.) scalding may occur at different temperatures.

WA TER HEA TING IGNITION SEQUENCE (Make sure gas and electric power are connected properly)

1. The ignition control module is powered and monitors the system, waiting for a call for heat from the thermostat.

2. The thermostat calls for heat by reading a resistance value within a given range directly proportional to water temperature.

3. The control module: a. Checks the pressure switch for an open circuit.

b. Energizes the blower. c. Checks the pressure switch for a closed circuit to prove

draft.

d. Sends line voltage to the hot surface igniter with a

20-second warm up period.

e. Opens the gas valve and checks the sensing rod for flame.

4. The burner heats the water to the desired thermostat setting. a. The resistance in the thermostat rises to the value

selected by the temperature control knob.

b. The control module closes the gas valve and 5 seconds

later, removes power from the blower.

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 infirm, or physically/mentally handicapped. If anyone using hot water in your home fits 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 satisfies your hot water needs, a means such as a mixing valve, shall 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 8 on page 9 and Figure 21 on page 15. Valves for reducing point of use temperature by mixing cold and hot water

Page 30

are also available. Consult Maytag Customer Service (1-800-788-8899). 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, see Figure 52.

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, to reduce the risk of scald injury . It is adjustable and must be reset to the desired temperature setting. The mark ( ) HOT indicative of approximately 120°F (49°C) is preferred starting point. Some states have a requirement for a lower setting. If you need hotter water, follow directions for temperature adjustment, but beware of the warnings in this section.

b.To increase the temperature press and release the

“HOTTER” button until the desired setting is reached.

NOTE: Holding down the button will not continue to lower or raise the temperature setting. The button must be pressed and released for each temperature change desired.

Pressing the “COOLER” pressing the “HOTTER”

button decreases temperature and

button increases the temperatures.

Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.

To avoid any unintentional changes in water temperature settings, the control has a tamper resistant feature for changing the temperature setting. To change the temperature setting follow these instructions:

1. “Wake Up” the temperature indicators by holding down both “COOLER” and “HOTTER” temperature adjustment buttons at the same time for one second, see Figure 49. One or two of the temperature indicators will light up. These indicators will only remain on for 30 seconds if no further buttons are pressed. Af ter 30 seconds the control will go back to “Sleep” mode.

2. Release both temperature adjustment buttons. a.To decrease the temperature press and release the

“COOLER” button until the desired setting is reached.

Tank (Sediment) Cleaning

Sediment build-up on the tank bottom may create varying amount of noise, if left in the tank will cause permanent tank failure. In some water areas, sediment can be removed by draining off approximately one gallon of water each month.

Vent System Inspection

• Flue gases may escape if vent pipe is not connected.

• Be alert for obstructed, sooted or deteriorated vent system to avoid serious injury or death.

• Do not store corrosive chemicals in vicinity of water heater.

• Chemical corrosion of flue and vent system can cause serious injury or death

Burner Inspection

Flood damage to a water heater may not be readily visible or immediately detectable. However, over a period of time a flooded water heater will create dangerous conditions which

can cause DEATH, SERIOUS BODIL Y INJURY , OR PROPERT Y DAMAGE. Contact the Maytag dealer from whom the appliance was purchased or call Maytag Customer Service at

At least once a year a visual inspection should be made of the main burner and pilot burner, see Figure 50.

Y ou should check for sooting. Soot is not normal and will imp air 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 fire causing death, serious injury, or property damage.

If improper flame characteristics are not evident, check for accumulation of lint or other foreign material that restricts or blocks the air openings in the heater or burner. Also check Combustion Air and Ventilation Requirements.

repair the unit! It

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 flow must not be obstructed.

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

• Rusted flakes around top of water heater.

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

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

Chemical vapor corrosion of the flue and vent system may occur if air for combustion contains certain chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes, bleach and process chemicals are typical compounds which are potentially corrosive.

If after inspection of the vent system you found sooting or deterioration, something is wrong. Call Maytag Customer

Service at 1-800-788-8899 for an authorized servicer or your local gas supplier to correct the problem and clean or replace the flue and venting before resuming operation of the water heater.

FIGURE 53.

Burner Cleaning

NOTE: Burner assembly must be handled carefully to avoid damaging the hot surface ignitor.

In the event your burner needs cleaning, following these instructions:

If inspection of the burner shows that cleaning is required, turn the “ON/OFF” rocker switch located on the control box to “OFF” position and allow the burner to cool.

Loose deposits on or around the burner can be removed by carefully using the hose of a vacuum cleaner inserted through the access door of the water heater. If the burner needs to be removed for additional cleaning, call the local gas utility or qualified service agent to remove and clean the burner with a soft brush. Clean main burner orifice with a suitable soft material. Correct the problem that requires the burner to be cleaned.

L.P. Gas Control Valve & Burner Assembly Replacement Information

For Propane (L.P.) Models Only

Your water heater is equipped with a Propane (L.P.) gas control valve and a main burner assembly with left hand threads for the following fittings and their connections.

• The connection between the manifold and the gas control valve (A and B) are left hand threads.

• The connection between the main burner orifice and the manifold (C to D) are left hand threads.

For ordering these replacement parts, please refer to the “Repair Parts List” section of this manual.

INSTALLED IN SUIT ABLE AREA: To insure sufficient ventilation and combustion air supply, proper clearances from the water heater must be maintained. See Facts to Consider About the Location section. Combustible materials such as clothing, cleaning materials, or flammable liquids, etc. must not be placed against or adjacent to the water heater which can cause a fire.

Anode Rod Inspection

The anode rod is used to protect the tank from corrosion. Most hot water tanks are equipped with an anode rod. The submerged rod sacrifices itself to protect the tank. Instead of corroding the tank, water ions attack and eat away the anode rod. This does not affect the water’s taste or color. The rod must be maintained to keep the tank in operating condition.

FIGURE 54.

Housekeeping

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

Anode deterioration depends on water conductivity, not necessarily water condition. A corroded or pitted anode rod indicates high water conductivity and should be checked and/ or replaced more often than an anode rod that appears to be intact. Replacement of a depleted anode rod can extend the life of your water heater. Inspection should be conducted by a qualified technician. At a minimum, the anode(s) should be checked annually after the warranty period.

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.

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

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

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

• Connect a hose to the drain valve and terminate to an adequate drain.

• OPEN the water heater drain valve to allow for tank draining.

Page 34

NOTE: If the water heater is going to be shut down and drained for an extended period, the drain valve should be left open with hose connected allowing water to terminate to an adequate drain.

• CLOSE the drain valve.

• Follow instructions in the Filling The Water heater section.

• Follow the lighting instructions in the Operation section to restart the water heater.

TROUBLESHOOTING

Start Up Conditions

Condensation

Whenever the water heater is filled with cold water, some condensate will form while the burner is on. A water heater may appear to be leaking when in fact the water is condensation. This usually happens when:

• A new water heater is filled with cold water for the first time.

• Burning gas produces water vapor In water heaters, particularly high efficiency models where flue temperatures are lower.

• Large amounts of hot water are used in a short time and the refill water in the tank is very cold.

Moisture from the products of combustion condense on the cooler tank surfaces and form drops of water which may fall onto the burner or other hot surfaces to produce a “sizzling” or “frying” noise.

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.

Water supply system may, because of such events as high line pressure, frequent cut-offs, the effects of water hammer among others, have installed devices such as pressure reducing valves, check valves, back flow preventers, etc., to control these types of problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices cause the water system to be closed. As water is heated, it expands (thermal expansion) and closed systems do not allow for the expansion of heated water.

The water within the water heater tank expands as it is heated and increases the pressure of the water system. If the relieving point of water heater’s temperature-pressure relief valve is reached, the valve will relief the excess pressure. The

temperature-pressure relief valve is not intended for the constant relief of thermal expansion. This is an unacceptable

condition and must be corrected. It is recommended that any devices installed which could create

a closed system have a by-pass and/or the system have an expansion tank or device to relieve the pressure built by thermal expansion in the water system. Thermal expansion tanks are available for ordering through the Maytag Customer Service Center (1-800-788-8899). Contact the local plumbing inspector, water supplier and/or call Maytag Customer Service at

1-800-788-8899 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.

Operational Conditions

Good venting is essential for a gas fired water heater to operate properly as well as to carry away products of combustion and water vapor.

Smoke / Odor

It is not uncommon to experience a small amount of smoke and odor during the initial start-up. This is due to burning off of oil from metal parts, and will disappear in a short while.

Thermal Expansion

Smelly Water

In each water heater there is installed at least one anode rod

(see parts section) for corrosion protection of the tank. Certain water conditions will cause a reaction between this rod and the water. The most common complaint associated with the anode rod is one of a “rotten egg smell”. This odor is derived from hydrogen sulfide gas dissolved in the water. The smell is the result of four factors which must all be present for the odor to develop:

• a concentration of sulfate in the supply water.

• little or no dissolved oxygen in the water.

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

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

Smelly water may be eliminated or reduced in some water heater models by replacing the anode(s) with one of less active material, and then chlorinating the water heater tank and all

Page 36

hot water lines. Contact Maytag Customer Service at

1-800-788-8899 for further information concerning an Anode Replacement Kit and this Chlorination Treatment.

If the smelly water persists after the anode replacement and chlorination treatment, we can only suggest that chlorination or aeration of the water supply be considered to eliminate the water problem.

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

FIGURE 57.

Not Enough or No 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 flammable and explosive. To prevent the possibility of injury under these conditions, we recommend the hot water faucet, located farthest away, be opened for several minutes before any electrical appliances which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.

High Temperature Limit Switch (Single-Use Type Energy Cut Off)

The thermostat has a built-in limit switch which will actuate in case of excessive water temperatures. The heater cannot be relit until the gas control valve is replaced. It is important that a serviceman be called to determine the reason for limit operation and thus avoid repeated thermostat replacement. Lower the temperature adjustment setting on new control. Call Maytag

Customer Service at 1-800-788-8899 for an authorized servicer.

Should overheating occur or the gas supply fail to shut off, turn “OFF” the manual gas control valve to the appliance.

1. Check the manual gas shut off valve to be sure it is open.

2. The ON/OFF switch on the control box must be “ON”.

3. The temperature button adjustment may be set too low. See the Temperature Regulation” section.

4. The gas company can check the gas input to see if it is correct. An under-fired water heater will not heat water as quickly.

5. Look for leaking or open hot water faucets. Make sure all are closed.

6. The cold water inlet temperature may be colder during the winter months. It will take longer to heat the water and seem like less hot water.

7. If you cannot find what is wrong, call Maytag Customer

Service 1-800-788-8899 for an authorized servicer.

There is a venting manual reset switch located on the draft hood. If the venting manual reset switch is activated, it will not reset itself. Before resetting this venting manual reset switch, check for flue blockage and propriety of the venting system. To reset the venting manual reset switch, press the red reset button.

NOTE: A period of time is necessary after an adjustment has been made for the water temperature to reach the new temperature setting.

2. If lower temperature settings will not lower the water temperature, call Maytag Customer Service 1-800-788-8899 for an authorized servicer.

Leakage Checkpoints

Read this manual first. Then before checking the water heater make sure the gas supply has been turned “OFF”, and never turn the gas “ON” before the tank is completely full of water.

Never use this water heater unless it is completely filled with water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater, see Figure 58.

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. Call Maytag Customer Service at

1-800-788-8899 for an authorized servicer.

Leakage from other appliances, water lines, or ground seepage should also be checked.

* To check where threaded portion enters tank, insert cotton

swab between jacket opening and fitting. If cotton is wet, follow “Draining” instructions in the Periodic Maintenance section and then remove fitting. Put pipe dope or teflon tape on the threads and replace. Then follow Filling the Water Heater instructions in the Installation Instructions section.

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

pipe connections may be leaking. C. *The primary anode rod fitting may be leaking. D. Small amounts of water from temperature-pressure relief

valve may be due to thermal expansion or high water

pressure in your area. E. *The temperature-pressure relief valve may be leaking at

the tank fitting. F. Water from a drain valve may be due to the valve being

slightly opened. G. *The drain valve may be leaking at the tank fitting. H. Combustion products contain water vapor which can

condense on the cooler surfaces of the tank. Droplets form

and drip onto the burner or run on the floor. This is common

at the time of start-up after installation and when incoming

water is cold. I. Water in the water heater bottom or on the floor may be from

condensation, loose connections, or the relief valve.

DO NOT replace the water heater until a full inspection of all

possible water sources is made and necessary corrective

steps taken.
