FOR INSTALLATIONS IN THE STATE OF CALIFORNIA

California Law requires that residential water heaters must be braced, anchored or strapped to resist falling or horizontal displacement due to earthquake motions. For residential water heaters up to 52 gallon capacity, a brochure with generic earthquake bracing instructions can be obtained from: Office of the State Architect, 400 P Street, Sacramento, CA 95814 or you may call 916-324-5315 or ask a water heater dealer.

However, applicable local codes shall govern installation. For residential water heaters of a capacity greater than 52 gallons, consult the local building jurisdiction for acceptable bracing procedures.

SAFETY PRECAUTIONS

Have the installer show you the location of the circuit breaker and how to shut it off if necessary. Turn off the circuit breaker if the water heater has been subjected to overheating, fire, flood, physical damage or if the ECO fails to shut off.

Read this manual entirely before installing or operating the water heater.

Use this appliance only for its intended purpose as described in this Use and Care

Manual.

Do not attempt to repair or replace any part of your water heater unless it is specifically recommended in this manual. All other servicing should be referred to a qualified technician.

Be sure your appliance is properly installed in accordance with local codes and the provided installation instructions.

READ AND FOLLOW THIS SAFETY INFORMATION

CAREFULLY.

SAVE THESE INSTRUCTIONS

Installing the water heater.

The location chosen for the water heater must take into consideration the following:

Local Installation Regulations

This water heater must be installed in accordance with these instructions, local codes, utility codes, utility company requirements or, in the absence of local codes, the latest edition of the National

Electrical Code. It is available from some local libraries or can be purchased from the National Fire Protection Association,

Batterymarch Park, Quincy, MA 02269 as booklet ANSI/NFPA 70.

Location

This water heater is designed to meet a wide range of applications. It fulfills a demand for a small water heater that can be installed in a limited space such as under countertops, in cabinets or in a closet.

Locate the water heater in a clean dry area as near as practical to hot water fixtures, or close to the water faucet most frequently used.

Locate the water heater in a clean dry area as near as practical to the area of greatest heated water demand. Long uninsulated hot water lines can waste energy and water.

Place the water heater in such a manner that the thermostat and element access panels can be removed to permit inspection and servicing such as removal of elements or checking controls.

The water heater and water lines should be protected from freezing temperatures. Do not install the water heater in outdoor, unprotected areas.

Make certain the floor underneath the water heater is strong enough to sufficiently support the weight of the water heater once it is filled with water.

CAUTION: The water heater should not be located in an area where leakage of the tank or connections will result in damage to the area adjacent to it or to lower floors of the structure. Where such areas cannot be avoided, it is recommended that a suitable catch pan, adequately drained, be installed under the water heater.

A—Diameter of water heater plus 2

B—Maximum 2

min.

A

NOTICE: Auxiliary catch pan MUST conform to local codes.

Catch Pan Kits are available from the store where the water heater was purchased, or any water heater distributor.

To open drain, line should be at least 3/4

ID and pitched for proper drainage.

Inspect Shipment

Inspect the water heater for possible damage. Check the markings on the rating plate of the water heater to be certain the power supply corresponds to the water heater requirements.

5

Installing the water heater.

Thermal Expansion

Determine if a check valve exists in the inlet water line.

It may have been installed in the cold water line as a separate back flow preventer, or it may be part of a pressure reducing valve, water meter or water softener.

A check valve located in the cold water inlet line can cause what is referred to as a “closed water system.” A cold water inlet line with no check valve or back flow prevention device is referred to as an “open” water system.

As water is heated, it expands in volume and creates an increase in pressure within the water system. This action is referred to as “thermal expansion.” In an “open” water system, expanding water which exceeds the capacity of the water heater flows back into the city main where the pressure is easily dissipated.

A “closed water system,” however, prevents the expanding water from flowing back into the main supply line, and the result of “thermal expansion” can create a rapid and dangerous pressure increase in the water heater and the system piping. This rapid pressure increase can quickly reach the safety setting of the relief valve, causing it to operate during each heating cycle. Thermal expansion, and the resulting rapid and repeated expansion and contraction of components in the water heater and piping system can cause premature failure of the relief valve, and possibly the heater itself. Replacing the relief valve will not correct the problem.

The suggested method of controlling thermal expansion is to install an expansion tank in the cold water line between the water heater and the check valve. The expansion tank is designed with an air cushion built in that compresses as the system pressure increases, thereby relieving the over pressure condition and eliminating the repeated operation of the relief valve. Other methods of controlling thermal expansion are also available. Contact your installing contractor, water supplier, or plumbing inspector for additional information regarding this subject.

NOTICE: Do not apply heat to the HOT or COLD water connections. If sweat connections are used, sweat tubing to adapter before fitting adapter to the water connections on heater.

Any heat applied to the water supply fittings will permanently damage the dip tube and/or heat traps.

Water Supply Connections

Refer to the illustrations on the following page for suggested typical installation. The installation of unions or flexible copper connectors is recommended on the hot and cold water connections so that the water heater may be easily disconnected for servicing. Connect cold water supply line to

3/4” pipe connection near bottom of water heater on the 6 gallon and 20 gallon models.

Install a shut-off valve and a drain valve

(not supplied with heater, except 2 1/2 gal.

models) in cold water line near water heater.

Connect hot water line to 3/4” pipe connection marked HOT on side near top of water heater. On the 2 1/2 gallon models, the hot and cold water connections are 1/2” pipe connections and are located on top of the heater. Local codes may require an antisiphon device on the water inlet of a side connect water heater.

A new combination temperature and pressure relief valve, complying with the Standard for Relief

Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22, is supplied and must be installed in the opening provided and marked for the purpose on the water heater. No valve of any type should be installed between the relief valve and the tank. Local codes shall govern the installation of relief valves.

WARNING: The pressure rating of the relief valve must not exceed 150 PSI, the maximum working pressure of the water heater as marked on the rating plate.

Relief Valve

The Btuh rating of the relief valve must not be less than the input rating of the water heater as indicated on the rating label located on the front of the heater

(1 watt=3.412 Btuh).

Connect the outlet of the relief valve to a suitable open drain so that the discharge water cannot contact live electrical parts or persons and to eliminate potential water damage.

Piping used should be of a type approved for hot water distribution. The discharge line must be no smaller than the outlet of the valve and must pitch downward from the valve to allow complete drainage (by gravity) of the relief valve and discharge line. The end of the discharge line should not be threaded or concealed and should be protected from freezing. No valve of any type, restriction or reducer coupling should be installed in the discharge line.

To Fill the Water Heater

WARNING: The tank must be full of water before heater is turned on. The water heater warranty does not cover damage or failure resulting from operation with an empty or partially empty tank.

Make certain the drain valve is completely closed.

Open the shut-off valve in the cold water supply line.

Open each hot water faucet slowly to allow the air to vent from the water heater and piping.

A steady flow of water from the hot water faucet(s) indicates a full water heater.

Installing the water heater.

Condensation

Condensation can form on the tank when it is first filled with water. Condensation might also occur with a heavy water draw and very cold inlet water temperature.

This condition is not unusual, and will disappear after the water becomes heated.

If, however, the condensation continues, examine the piping and fittings for possible leaks.

CAUTION: The presence of water in the piping and water heater does not provide sufficient conduction for a ground. Non-metallic piping, dielectric unions, flexible connectors etc. can cause the water heater to be electrically isolated.

NOTICE: This guide recommends minimum branch circuit sizing and wire size based on National

Electric Code. Refer to wiring diagrams in this manual for field wiring connections.

Additional information on this subject may be found at www.rheem.com under

“Library”. Scroll down to the Technical

Service Bulletins 1300 Series Section and choose Bulletin #1303.

Operating the water heater.

CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipe as the water begins to flow. Do not smoke or use an open flame near the faucet at the time it is open.

Safety Precautions

Do turn off power to water heater if it has been subjected to over heating, fire, flood, physical damage.

Do Not turn on water heater unless it is filled with water.

Do Not turn on water heater if cold water supply shut-off valve is closed.

If there is any difficulty in understanding or following the

Operating Instructions or the

Care and Cleaning section, it is recommended that a qualified person or serviceman perform the work.

CAUTION: The cause of the high temperature condition must be investigated by qualified service technician and corrective action must be taken before placing the water heater in service again.

Safety Controls

The water heater is equipped with a combination thermostat and temperature limiting control (ECO) that is located above the heating element in contact with the tank surface. If for any reason the water temperature becomes excessively high, the temperature limiting control (ECO) breaks the power circuit to the heating element.

Once the control opens, it must be reset manually.

To reset the temperature limiting control:

Turn off the power to the water heater.

Remove the jacket access panel(s) and insulation.

The thermostat protective cover should not be removed.

Press the red RESET button.

Replace the insulation and jacket access panel(s) before turning on the power to the water heater.

Emergency Instructions

WARNING: If the water heater has been subjected to flood, fire, or physical damage, turn off power and water to the water heater.

Do not operate the water heater again until it has been thoroughly checked by qualified service personnel.

12

DANGER: There is a hot water scald potential if the thermostat is set too high.

Households with small children, disabled, or elderly persons may require a 120°F or lower thermostat setting to prevent contact with HOT water.

Water Temperature Setting

The temperature of the water in the water heater can be regulated by setting the temperature dial of the adjustable surface mounted thermostat(s) located behind the jacket access panel(s).

Dual element heaters have two thermostats.

Safety and energy conservation are factors to be considered when selecting the water temperature setting of the water heater’s thermostat(s). The lower the temperature setting, the greater the savings in energy and operating costs.

To comply with safety regulations the thermostat(s) are factory set at 120°F or less where local codes require. This is the recommended starting point.

Water temperatures above 125°F can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined in this manual and on the label on the water heater. This label is located on the water heater near the thermostat access panel.

Mixing valves are available for reducing point of use water temperature by mixing hot and cold water in branch water lines.

Contact a licensed plumber or the local plumbing authority for further information.

Care and cleaning of the water heater.

Draining the Water Heater

CAUTION: Shut off power to the water heater before draining water.

DANGER: Before manually operating the relief valve, make certain no one will be exposed to the hot water released by the valve. The water drained from the tank may be hot enough to present a scald hazard and should be directed to a suitable drain to prevent injury or damage.

In order to drain the water heater, turn off the cold water supply. Open a hot water faucet or lift the handle on the relief valve to admit air to the tank.

Attach a garden hose to the drain valve on the water heater and direct the stream of water to a drain. Open the valve.

DANGER: Before manually operating the relief valve, make certain no one will be exposed to the danger of coming in contact with the hot water released by the valve.

The water may be hot enough to create a scald hazard. The water should be released into a suitable drain to prevent injury or property damage.

NOTICE: If the temperature and pressure relief valve on the hot water heater discharges periodically, this may be due to thermal expansion in a closed water system. Contact the water supplier or your plumbing contractor on how to correct this. Do not plug the relief valve outlet.

Routine Preventative Maintenance

Properly maintained, your water heater will provide years of dependable troublefree service.

It is suggested that a routine preventive maintenance program be established and followed by the user.

A water heater’s tank can act as a setting basin for solids suspended in the water.It

is therefore not uncommon for hard water deposits to accumulate in the bottom of the tank. It is suggested that a few quarts of water be drained from the water heater’s tank every month to clean the tank of these deposits.

It is further recommended that a periodic inspection of the operating controls, heating element and wiring should be made by service personnel qualified in electric appliance repair.

Most electrical appliances, even when new, make some sound when in operation.

If the hissing or singing sound level increases excessively, the electric heating element may require cleaning. Contact a qualified installer or plumbing contract to inspect.

Rapid closing of faucets or solenoid valves in automatic water using appliances can cause a banging noise heard in a water pipe. Strategically located risers in the water pipe system or water hammer arresting devices can be used to minimize the problem.

The anode rod should be removed from the water heater’s tank annually for inspection and replaced when more than 6

″ of core wire is exposed at either end of the rod.

At least once a year, lift and release the lever handle on the temperature pressure relief valve, located near the top of the water heater, to make certain the valve operates freely. Allow several gallons to flush through the discharge line to an open drain.

Make sure the cold water supply is turned off before removing anode rod.

NOTICE: Do not remove the anode rod from the water heater’s tank, except for inspection and/or replacement, as operation with the anode rod removed will shorten the life of the glass lined tank and will exclude warranty coverage.

NOTICE: Refer to the

Hydrogen Gas Caution in the

Operating Instructions.

Vacation and Extended Shut-Down

If the water heater is to remain idle for an extended period of time, the power and water to the appliance should be turned off to conserve energy and prevent a build-up of dangerous hydrogen gas.

After a long shut-down period, the water heater’s operation and controls should be checked by qualified service personnel.

Make certain the water heater is completely filled again before placing it in operation.

Before You Call For Service…

Troubleshooting Tips

Save time and money! Review the chart on this page first and you may not need to call for service.

Problem

Rumbling noise

Relief valve producing popping noise or draining

Rattling noise during periods of water usage

Not enough or no hot water

Water is too hot

Possible Causes

Water conditions in your home caused a build up of scale or mineral deposits on the heating elements.

Pressure build up caused by thermal expansion in a closed system.

Internal heat trap fittings in operation.

Water usage may have exceeded the capacity of the water heater.

A fuse is blown or a circuit breaker tripped.

Electric supply may be off.

The thermostat may be set set too low.

Leaking or open hot water faucets.

Electric service to your home may be interrupted.

Improper wiring.

Manual reset limit (ECO)

Cold water inlet temperature may be colder during the winter months.

The thermostat is set too high.

What To Do

Remove and clean the heating elements.

This is an unacceptable condition and must be corrected. Contact the water supplier or plumbing contractor on how to correct this. Do not plug the relief valve outlet.

● This is normal for heat trap fittings when in operation and does not indicate a need for service.

Wait for the water heater to recover after an abnormal demand.

Replace fuse or reset circuit breaker.

Make sure electric supply to water heater and disconnect switch, if used, are in the ON position.

See the Temperature regulation of the water heater section of this manual.

Make sure all faucets are closed.

Contact the local electric utility.

See the Installing the water heater section of this manual.

See the Temperature regulation of the water heater section of this manual.

This is normal. The colder inlet water takes longer to heat.

See the Temperature regulation of the water heater section of this manual.

CAUTION: For your safety DO NOT attempt repair of electrical wiring, thermostats, heating elements or other safety devices. Refer repairs to qualified service personnel.
