IMPORTANT SAFETY INFORMATION. READ ALL INSTRUCTIONS BEFORE USING.

The chart shown above may be used as a guide in determining the proper water temperature for your home.

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

Maximum water temperatures occur just after burner has shut off. To find water temperature being delivered, turn on a hot water faucet and place a thermometer in the water stream and read the thermometer.

The temperature of the water in the heater can be regulated by setting the temperature dial on the front of the gas control (thermostat). To comply with safety regulations the thermostat was set at its lowest

setting before the water heater was shipped from the factory.

The illustration at the left details the approximate water temperature for each mark on the Gas Control (Thermostat) Temperature Dial.

DANGER: Hotter water increases the potential for

Hot Water SCALDS.

DANGER!

WATER TEMPERATURE SETTING

Safety and energy conservation are factors to be considered when selecting the water temperature setting of water heater’s thermostat. Water temperatures above 125°F. can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined on the label pictured below. This label is also located on the water heater.

Notice: 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.

DANGER

HOT

BURN

Water temperature over 125°F can cause severe burns instantly or death from scalds.

Children, disabled and elderly are at highest risk of being scalded.

See instruction manual before setting temperature at water heater.

Feel water before bathing or showering.

Temperature limiting valves are available, see manual.

LP and natural gas have an odorant added to aid in detecting a gas leak. Some people may not physically be able to smell or recognize this odorant. If you are unsure or unfamiliar with the smell of LP or natural gas, ask the gas supplier. Other conditions, such as “odorant fade”, which causes the odorant to diminish in intensity, can also hide or camouflage a gas leak.

DANGER!

LIQUEFIED PETROLEUM (LP - PROPANE OR BUTANE) AND NATURAL GAS MODELS

●●

This water heater is supplied with a thermostatic gas valve that is convertible to LP from natural gas. Be sure to read and carefully follow the Conversion Instructions included in this manual when converting the valve from one type of gas to another.

●●

After conversion, be certain that the gas supplied to the heater is the type that the valve has been converted for (LP for heaters converted to LP use, and natural gas for heaters converted to natural gas use). This water heater will not operate safely if connected to a fuel type other than the one the gas valve is converted for.

●●

LP gas must be used with great caution. It is heavier than air and will collect first in lower areas making it hard to detect at nose level.

●●

Before attempting to light the water heater, make sure to look and smell for gas leaks. Use a soapy solution to check all gas fittings and connections. Bubbling at a connection indicates a leak that must be corrected. When smelling to detect an LP leak, be sure to sniff near the floor also.

●●

Gas detectors are recommended in LP and natural gas applications and their installation should be in accordance with the manufacturer’s recommendations and/or local laws, rules, regulations or customs.

●●

It is recommended that more than one method, such as soapy solution, gas detectors, be used to detect leaks in LP gas applications.

DANGER: If a gas leak is present or

suspected:

●●

Do not attempt to find the cause yourself.

●●

Do not

try to light any appliance.

●●

Do not

touch any electrical switch.

●●

Do not

use any phone in your building.

●●

Leave the house immediately and make sure your family and pets leave also.

●●

Leave the doors open for ventilation and contact the gas supplier, a qualified service agency or the fire department.

●●

Stay away from the house (or building) until the service call has been made, the leak is corrected and a qualified agency has determined the area to be safe.

Have the installer show you the location of the gas shut-off valve and how to shut it off if necessary. Turn off the manual shut-off valve if the water heater has been subjected to overheating, fire, flood, physical damage or if the gas supply 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.

● Be sure your appliance is properly installed

by a qualified technician in accordance with the provided installation instructions.

Installing the water heater.

The installation of this water heater must be in accordance with the Manufactured Home Construction and Safety Standard (Title 24, CFR; Part 3280) and the following instructions; instructions supplied with the roof jack assembly, local codes, and utility company requirements governing the installation of water heaters in manufactured homes (mobile homes) and/or in the absence of local codes, the latest edition of The National Fuel Gas Code, ANSI Z223.1.

Location

This water heater must be installed within an enclosure so as to separate the water heater's combustion and venting system from the interior atmosphere of the manufactured home.

All air for combustion must be obtained from the outside atmosphere, and the products of combustion (flue gases) must be discharged directly to the outside atmosphere through the gas vent roof jack assembly. There must not be any door or other opening into the water heater enclosure from the inside of the manufactured home.

Refer to installation methods A, B or C as shown on page 9 of this manual. The water heater enclosure access panel (door) must be in the outside wall of the manufactured home. Any opening for piping must be sealed. Minimum ceiling height within enclosure is 6'6".

Install the water heater with minimum clearance from combustible construction of 0-inch sides and rear; 3 inches from front of control; 12 inches top. If clearances stated on Instruction/Warning label, located on front of heater, differ from the aforementioned clearances, install heater according to the clearances stated on the Instruction/Warning label.

The water heater may be installed on combustible flooring, but not directly on carpeting.

If the water heater must be installed on carpeting, place a wood or metal panel beneath the water heater extending beyond its full width and depth at least 3” in all directions. If the water heater is installed in an alcove or closet, the entire floor must be covered by the panel.

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

CAUTION: Provisions should be made so that in the event the water heater or one of its fittings were to leak, the resulting flow of water will not cause damage to the manufactured home.

CAUTION: DO NOT subject the water heater to any water distribution system air pressure test. The water heater should either be isolated with valves at the inlet and outlet water connections or disconnected during the test. Failure to properly isolate the water heater during an air pressure test presents a hazard to life and property. With a water pressure test the water heater need not be isolated.

WARNING: Combustible

construction refers to adjacent walls and ceilings and should not be confused with combustible or flammable products and materials. Combustible and/or flammable products and materials should never be stored in the vicinity of this or any gas appliance.

Installing the water heater.

Thermal Expansion

Determine if a check valve exists in the inlet water line. Check with your local water utility company. 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 the 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 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 (see illustration below). 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.

Water Supply Connections

Refer to the illustration on page 11 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 if

necessary. The HOT and COLD water connections are clearly marked and are 3/4” NPT on all models. Install a shut-off valve in the cold water line near the water heater.

IMPORTANT: 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 cold water connections on heater. Any heat applied to the cold water supply fittings will permanently damage the connection nipples.

Installing 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.

To Fill the Water Heater

Make certain that drain valve is closed, then 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.

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 temperatures.

Drops of water falling on the burner can produce a sizzling or pinging sound, and the water may also be seen beneath the water heater.

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.

Additional information on this subject may be found at www.rheem.com, under “Library”, scroll down to the Technical Service Bulletins 1400 Series Section and choose Bulletin #1402.

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 remain 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.

Relief Valve

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.

The BTUH rating of the relief valve must equal or exceed the BTUH input of the water heater as marked on its rating plate.

Position the outlet of the relief valve above a suitable open drain 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.

WARNING: Never use an open flame to test for gas leaks, as bodily injury, property damage or death could result.

Leak Testing

The water heater and its gas connections must be leak tested at normal operating pressures before it is placed in operation.

Turn on the manual gas shut-off valve near the water heater.

Use a soapy water solution to test for leaks at all connections and fittings. Bubbles indicate a gas leak that must be corrected.

The factory connections to the thermostat should also be leak tested after the water heater is placed in operation.

Pressure Testing the Gas Supply System

The water heater and its manual gas shut-off valve must be disconnected

from the gas supply piping system during any high pressure testing of that system at pressures in excess of 1/2 psi (14″ w.c.).

The water heater must be isolated from the gas piping system by closing the manual gas shut-off valve during any pressure testing of the gas supply piping at pressures equal to or less than 1/2 psi (14″ w.c.).

Gas Supply

Check the markings on the water heater’s rating plate to be certain the type of gas being furnished corresponds to that for which the water heater is built. The water heater can be converted from natural gas to LP or vice versa. See the Conversion Instructions section of this manual.

The branch gas supply line to the water heater should be clean 1/2″ black steel pipe or other approved gas piping material.

A ground joint union or ANSI design certified semi-rigid or flexible gas appliance connector should be installed in the gas line close to the water heater. A manual gas shut-off valve should be at least 5 ft. above the floor and readily accessible.

Compound used on the threaded joints of the gas piping must be of the type resistant to the action of LP gas. Use compound sparingly on male threads only.

A sediment trap should be installed at the bottom of the gas line.

Do not use excessive force (over 31.5 ft lbs.) in tightening the pipe joint at the thermostat inlet, particularly if teflon pipe compound is used, as the valve body may be damaged.

The inlet gas pressure to the water heater must not exceed 14″ w.c. for natural or LP gas. For purposes of input adjustment, the minimum inlet gas pressure (with main burner on) is shown on the water heater rating plate. If high or low gas pressures are present, contact your gas supplier for correction.

Installing the water heater.

High Altitude

Ratings of gas appliances are based on sea level operation and need not be changed for installations at elevations up to 2,000 feet.

For installations above 2,000 feet, reduce the input per the the National Gas Fuel Code for each 1,00 feet above sea level. Contact the local gas supplier for further information.

WARNING: Failure to install a water heater suitable for the altitude at the location it is intended to serve, can result in improper operation of the appliance resulting in property damage and/or, producing carbon monoxide gas, which could result in personal injury, or death.

For increased energy efficiency, some water heaters have been supplied with two 24” sections of pipe insulation.

Please install the insulation, according to the illustrations above, that best meets your requirements.

The wide reference mark near WARM on the rim of the temperature dial, represents an approximate water temperature of 120°F.

The long wide reference mark, to the left, represents an approximate water temperature of 130°F.

Each reference mark above or below these points indicates an approximate change of 10°F.

To adjust the temperature, turn the temperature dial to an initial setting of 120°F.

A condition known as “stacking” or “layering” can occur when a series of short and frequent hot water draws are taken.

The hottest temperature water will be at the top of the tank, closest to the outlet pipe delivering hot water to the home.

Stacking can cause this top layer of water to be hotter than the water toward the bottom of the tank near the gas control (thermostat).

Therefore, always remember to test the water temperature with your hand before use and remember that hotter water increases the risk of scald injury.

Also, always supervise young children or others who are incapacitated.

The gas control (thermostat) is constructed with a built in safety shut-off device designed to shut off the gas supply to the burner if the pilot flame is extinguished for any reason.

The gas control (thermostat) is also equipped with a single use gas shut off device that will shut off the gas supply to the burner if the water heater exceeds normal operating temperatures. Refer to the (Before You Call For Service) section of this manual, or contact your dealer.

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

If the water heater has been subjected to fire, flood or physical damage, turn off the manual gas control (shut-off) valve, and do not operate the water heater again until it has been checked by qualified personnel.

WARNING

READ ALL INSTRUCTIONS BEFORE LIGHTING

Care and cleaning of the water heater.

Draining the Water Heater

CAUTION: Shut off gas to the water heater at the thermostat gas cock or manual shut-off valve 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.

Routine Preventative Maintenance

Properly maintained, your water heater will provide years of dependable trouble-free service.

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

It is further recommended that a periodic inspection of the thermostat, burner, relief valve, internal flue-way and venting system should be made by service personnel qualified in gas appliance repair.

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.

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.

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.

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.

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

Inspect air inlet assembly beneath mobile home (if applicable) to make certain flow of air to the water heater for adequate combustion (proper burner operation) and ventilation is not obstructed.

Housekeeping

To insure sufficient ventilation and combustion air supply, proper clearances must be maintained.

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.

DANGER: Failure to perform the recommended Routine Preventative Maintenance can harm the proper operation of this water heater, which can cause carbon monoxide dangers, excessive hot water temperatures and other potentially hazardous conditions.

DANGER: Hotter water increases the potential for Hot Water Scalds.

DANGER: Combustible materials, such as clothing, cleaning materials, or flammable liquids, etc., must not be placed against or next to the water heater.

Venting System Inspection

It is recommended the water heater’s internal flue be inspected annually to be certain it is clean by removing the draft hood and flue baffle.

When reinstalling the flue baffle make certain it is hung securely by its hanger at the top of the flue way.

Remove any scale that may have fallen on the burner or floor shield and reinstall the draft hood.

Make certain the draft hood is fastened to the water heater top pan and roof jack vent is properly positioned and securely attached with sheet metal screws.

If after inspection of the vent system you found sooting or deterioration call the local gas utility to correct the problem and clean or replace the flue baffle and venting before resuming operation of the water heater.

Test for spillage at the draft hood relief opening after 5 minutes of burner operation. Use a flame of a match or candle or smoke.

Burner Inspection

Visually inspect the burners annually.

Through the site glass, inspect the pilot burner flame with the main burner off and inspect the main burner while firing.

If any unusual burner operation is noted, the water heater should be shut off until qualified service assistance can be obtained.

For cleaning, remove the burner from the water heater. A vacuum cleaner can be used on the burner and floor shield inside the water heater. The burner can also be cleaned by scrubbing with mild detergent.

CAUTION: For your safety, cleaning of

the main burner should be performed only by qualified service personnel.
