LOCATING THE NEW WATER HEATER

FACTS TO CONSIDER ABOUT THE LOCA TION

HOTTER WA TER CAN SCALD: Water heaters are intended to produce hot water. W ater 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 local plumbing contractor. Consult a Qualified Installer or Service Agency. Follow mixing valve manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “T emperature Regulation” section in this manual.

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.

Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed:

1. Select a location indoors as close as practical or centralized to the water piping system as possible. The water heater should be located in an area not subject to freezing temperatures.

2. Selected location must provide adequate clearances (4”) for servicing parts such as the thermostats, drain valve and relief valve. Adequate clearance for servicing this appliance should be considered before installation, such as changing the anodes, etc.

LOCATING THE NEW WATER HEATER

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 from your local plumbing contractor. 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.

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 .

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

INSULA TION BLANKETS

Insulation blankets are available to the general public for external use on electric water heaters but are not necessary with this product. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Y our water heater meets or exceeds the National Appliance Energy Conversation 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 below. Failure to follow these instructions can result in fire, serious personal injury , or death.

•

Do not cover the temperature and pressure relief (T & P) valve with an insulation blanket.

•

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 for placement on the

•

blanket directly over the existing labels.

INSTALLING THE NEW WATER HEATER

WATER PIPING

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 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. V alves for reducing point of use temperature by mixing cold and hot water are also available.

Consult a Qualified Installer or Service Agency . Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “T emperature Regulation” section in this manual.

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

T oxic 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, 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 exp ands (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 or device to relieve the pressure built by thermal expansion in the water system. Expansion tanks are available for ordering through a local plumbing contractor. Contact the local water supplier and/or a

service agency for assistance in controlling these situations.

When testing the water ways, H.U.D. Standards state: “Water distribution system: All water piping in the water distribution system shall be subjected to a pressure test. The test shall be made by subjecting the system to air or water at 100 psi for 15 minutes without loss of pressure. When air pressure is used, the water heater

shall not be connected during the test.”

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 3 shows the typical attachment of the water piping to the water heater. The water heater is equipped with 3/4 inch NPT water connections.

NOTE: If using copper tubing, solder tubing to an adapter before attaching the adapter to the cold water inlet connection. Do not solder the cold water supply line directly to the cold water inlet, it will harm the dip tube and damage the tank.

• If water piping system is to be air pressure tested, the water heater must be disconnected from the water piping system.

• Failure to disconnect the water heater during air pressure testing of the water system could result in DEA TH, SERIOUS BODIL Y INJURY , OR PROPERTY DAMAGE.

FIGURE 3.

WA TER PIPING PRESSURE TEST

This section is only for the manufacturer installing the water heater when the installation is to comply with H.U.D. Standards.

FIGURE 4.

TEMPERATURE-PRESSURE RELIEF VAL VE

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 Water Supply Systems, ANSI Z21.22 • CSA 4.4, 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.

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 must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet (9.14 m), or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve.

No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6 inch air gap is provided. To prevent bodily injury , hazard to life, or property damage, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage.

The Discharge Pipe:

• Shall not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions.

• Shall not be plugged or blocked.

• Shall be of material listed for hot water distribution.

FIGURE 5.

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 HEA TER

• Shall be installed so as to allow complete drainage of both the temperature-pressure relief valve, and the discharge pipe.

• Shall terminate beneath the manufactured home.

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

The temperature-pressure relief valve must be manually operated at least once a year. Caution should be taken to ensure that (1) no one is in front of or around the outlet of the 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.

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. Water must flow from the hot water faucet before turning “ON” electrical supply to the water heater.

To fill the water heater with water:

1. 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.

2. 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.

3. T o 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.

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

T&P VALVE and PIPE INSULATION (On Selected Models)

Remove insulation for T&P V alve and pipe connections from carton. Fit pipe insulation over the incoming cold water line and the hot water

line. Make sure that the insulation is against the side jacket of the heater.

Secure all insulation using tape.

Fit T&P V alve insulation over valve. Make sure that the insulation does not interfere with the lever or outlet of the T&P valve.

for grounding if all the following conditions are met:

• The length in any ground return path does not exceed 6 feet.

• The circuit conductors contained therein are protected by overcurrent devices rated at 20 amperes or less.

• The conduit or tubing is terminated in fittings approved for grounding.

For complete grounding details and all allowable exceptions, refer to the current edition of the National Electrical Code NFPA 70.

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

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

6. The water heater must be electrically “grounded” by the installer. A green ground screw has been provided in the water heater’s junction box. Connect ground wire to this location.

WA TER HEA TERS EQUIPPED FOR ONE VOLT AGE ONL Y: This water heater is equipped for one type voltage only . Check the rating plate near the bottom access panel for the correct voltage. DO NOT use this water heater with any voltage other than the one shown on the model rating plate. Failure to use the correct voltage can cause problems which can result in DEATH, SERIOUS BODIL Y INJUR Y , OR PROPERTY DAMAGE. If you have any questions or doubts consult your electric company .

If wiring from your fuse box or circuit breaker box was aluminum for your 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 a competent electrician. Contact a local electrical contractor and/or the local electric utility.

7. Replace the wiring junction cover using the screws provided.

FIGURE 8.

TEMPERATURE REGULATION

Due to the nature of the typical water heater, the water temperature in certain situations may vary up to 30°F (16.7 °C) higher or lower at the point of use such as, bathtubs, showers, sink, etc.

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.

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, 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 from your local plumbing contractor. Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “T emperature Regulation” section in this manual.

TEMPERATURE ADJUSTMENT

T o change the temperature setting: NOTE: It is not necessary to adjust the upper thermostat. However, if it

is adjusted above the factory set point (120°F (49°C)/HOT) it is recommended that it not be set higher than the lower thermostat setting.

Turn “OFF” the heater electrical supply . Do not attempt to adjust

1. thermostat with power on.

2. Remove the thermostat outer doors and insulation covers from the thermostats. Do not remove the plastic personnel protectors covering the thermostats.

3. Using a flat tip screwdriver, rotate the adjustment knob to the desired temperature setting.

4. Replace the insulation covers and outer doors and turn “ON” heater electrical supply.

THIS WATER HEATER IS EQUIPPED WITH AN ADJUSTABLE THERMOSTAT TO CONTROL WATER TEMPERATURE. HOT WATER TEMPERATURES DESIRED FOR AUTOMATIC DISHWASHER AND LAUNDRY USE CAN CAUSE SCALDS RESULTING IN SERIOUS PERSONAL INJURY AND/OR DEATH. THE TEMPERA TURE A T WHICH INJURY OCCURS V ARIES WITH THE PERSON’S AGE AND THE TIME OF THE EXPOSURE. THE SLOWER RESPONSE TIME OF CHILDREN, AGED OR DISABLED PERSONS INCREASES THE HAZARDS TO THEM. NEVER ALLOW SMALL CHILDREN TO USE A HOT WA TER TAP , OR TO DRAW THEIR OWN BATH WATER. NEVER LEAVE A CHILD OR DISABLED PERSON UNA TTENDED IN A BA THTUB OR SHOWER.

It is recommended that lower water temperatures be used to avoid the risk of scalding. It is further recommended, in all cases, that the water temperature thermostat be set for the lowest temperature which satisfies your hot water needs, see Figure 9. This will also provide the most energy efficient operation of the water heater . Thermostat(s) are factory set at 120°F (49°C) unless specified differently by state requirements.

KEEPING THE THERMOSTA T SETTING AT 120°F (49°C) WILL REDUCE THE RISK OF SCALDS.

Figure 9 shows the approximate time-to-burn relationship for normal adult skin.

TEMPERA TURE SETTINGS

It is recommended that the dial be set lower whenever possible.

system. Expansion tanks are available for ordering through a

water

local plumbing contractor. Cont act the local water heater supplier or service agency 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 necessarily represent harmful or dangerous conditions.

“AIR” IN HOT WA TER F AUCETS

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 WA TER TEMPERATURE SHUT OFF SYSTEM

A non-adjustable high temperature limit control operates before steam temperatures are reached. The high limit is in the same area as the upper thermostat and must be reset manually when it operates. BECAUSE THE HIGH LIMIT OPERATES ONLY WHEN ABNORMALLY HIGH W A TER TEMPERA TURES ARE PRESENT, IT IS IMPORT ANT THAT A QUALIFIED SER VICE AGENT BE CONT ACTED TO DETERMINE THE REASON FOR OPERA TION BEFORE RESETTING.

OPERA TIONAL CONDITIONS

SMELL Y WA TER

In each water heater there is installed at least one anode rod (see parts sections) 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” in the hot water. 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. A concentration of sulfate in the supply water . B. Little or no dissolved oxygen in the water. C . A sulfate reducing bacteria which has accumulated within the water

heater (this harmless bacteria is nontoxic to humans).

D. 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 the local water heater supplier or service agency 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.

• Turn “OFF” the heater electrical supply. Do not attempt to reset thermostat with power on.

• Remove the two screws securing the outer door and remove door.

• Remove the insulation block and pad to expose the reset button opening.

• Reset the high limit by pushing in the red button marked “RESET”.

• Replace the insulation block and pad so that it completely covers the thermostat and element.

• Replace the outer door.

• Turn “ON” electric power to the water heater.

PERIODIC MAINTENANCE

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.

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 then 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, and at a minimum should be checked annually after the warranty period.

TEMPERA TURE-PRESSURE RELIEF VAL VE OPERATION

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 your local water supplier or service agency for further information. Do not plug the temperature-pressure relief valve.

DRAINING

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

1. Turn electrical supply “OFF”.

The temperature-pressure relief valve must be manually operated at least once a year.

When checking the temperature-pressure relief valve operation, make sure that (1) no one is in front of or around the outlet of the temperaturepressure 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 10.

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

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

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

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

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

6. Close the drain valve.

7. Follow the instructions in the “Filling the Water Heater” section.

SERVICE

If a condition persists or you are uncertain about the operation of the water heater contact a service agency .

Use this guide to check a “Leaking” water heater. Many suspected “Leakers” are not leaking tanks. Often the source of the water can be found and corrected.

If you are not thoroughly familiar with your water heater and safety practices, contact a qualified installer to check the water heater .

LEAKAGE CHECKPOINTS

Read this manual first. Then before checking the water heater make sure the electrical power supply has been turned “OFF” before checking the tank for leakage.

*A. Condensation and dripping may be seen on pipes if the water

temperature is low in humid weather or pipe connections may be leaking.

*B. The anode rod fitting may be leaking.

C . Small amounts of water from temperature-pressure relief valve

may be due to thermal expansion or high water pressure in your area. If the valve is not piped to an open drain the released water could be mistaken for a leaking heater .

FIGURE 24.

*D . The temperature-pressure relief valve may be leaking at the tank

fitting.

E . The element may be leaking at the tank fitting. Turn electrical power

“OFF”, remove outer door, insulation block and pad. If leaking around the element, follow proper draining instructions and remove element. Reposition or replace gasket on element. Place element into opening and tighten securely. Then follow “Filling the W ater Heater” instructions in the “Installing the New Water Heater” section.

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

condensation, loose connections, or the relief valve. DO NOT replace the water heater until a full inspection of all possible water sources is made and necessary corrective steps taken.

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

* T o check where threaded portion enters t ank, insert cotton swab

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