THIS MANUAL HAS BEEN PREPARED TO ACQUAINT

YOU WITH THE INSTALLATION, OPERATION AND

MAINTENANCE OF YOUR GAS WATER HEATER AND

TO PROVIDE IMPORTANT SAFETY INFORMATION.

WE URGE YOU TO READ ALL INSTRUCTIONS

THOROUGHLY before attempting installation or operation of your water heater. Keep these instructions for future reference.

The manufacturer of this water heater will not be liable for any damages caused by failure to comply with the installation and operating instructions outlined on the following pages. These instructions are a guide for the correct installation of your water heater. If you lack the necessary skills required or have difficulty following the directions, you should not proceed but get help from a qualified person for that part of the installation you do not understand. Your gas-fired water heater is designcertified by the American Gas Association Laboratories. The installation should conform with the local code or the authority having jurisdiction, or in the absence of such, the

National Gas Code. ANSI Z223.1 (NFPA 54) 1992. A copy of the 1992 edition of the Code can be purchased from A.G.A.

Order Processing, 1515 Wilson Boulevard, Arlington, VA

22209 (703) 841-8559. A rating plate identifying your water heater will be found next to the gas control valve (thermostat).

When referring to your water heater always have the information listed on the rating plate readily available.

PRESSURE BUILD-UP IN

CLOSED WATER SYSTEMS

The water utility supply meter may contain a check valve, back flow preventer or water pressure reducing valve. This will create a closed water system. During the heating cycle of the water heater, the water expands creating a pressure build-up in the water system. A temperature and pressure relief valve must be installed on the water heater (150 PSI maximum pressure setting. See Temperature and Pressure Relief Valve). To prevent the temperature and pressure relief valve from discharging hot water, loss of energy, and reduce the possible build-up of lime on the temperature and pressure relief valve seat.

AN EXPANSION TANK MUST BE INSTALLED on the cold water supply line. For every 50 U.S. gallons of stored water, the expansion tank must have a minimum capacity of 1.5

U.S. gallons.

If water heater is installed in a closed water system, contact the water supplier or local plumbing inspector on how to control this situation.

130931 Rev April ʻ07

LOCATION

Location selection should be as close to the stack or chimney as practical and as centralized with the piping system as possible. Water heater should be located in an area not subject to freezing temperatures.

The water heater should be located so that the controls and drain are easily accessible (at least 24 inches in front of the water heater). The heater should be located in an area where leakage of the tank or connections will not result in damage to the area adjacent to the water heater or to lower floors of the structure. When such locations cannot be provided, a suitable drain pan must be installed under the heater. Such pans must limit the water level to a maximum depth of 1 3/4 inches inside of pan, have a minimum length and width of at least two inches greater than the diameter of the heater, and must be piped to an adequate drain. The pan must not restrict combustion air flow. (Figure 6)

Under no circumstances is the manufacturer to be held liable for any water damage in connection with this water heater.

WARNING

When this heater is installed directly on carpeting, carpeting must be protected by a metal or wood panel beneath the appliance extending beyond the full width and depth of the appliance by at least 3 inches in any direction, or if the appliance is installed in an alcove or closet, the entire floor must be covered by the panel.

would include those areas where flammable liquids (such as gasoline, solvents, liquefied propane or butane, etc.) or other substances (such as adhesives, etc.) all of which emit flammable vapors, may be improperly stored or used. Because of natural air movement in a room or other enclosed space, flammable vapors can be carried some distance from where their liquids are being used or stored. The gas water heater pilot flame or main burner can ignite such vapors. The resulting flash-back and tire can cause death or serious burns to anyone in the area, as well as property damage.

For these reasons the water heater must not be installed in an area where there may be flammable vapors. If such flammables must be used, all gas burning appliances in the vicinity must be shut off, including their pilot lights, to avoid vapors igniting and open doors and windows for ventilation .

If installation in a garage is your only option, the 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

BUT NOT eliminate the chances of flammable vapors from a spill being ignited, gasoline or other flammable substances must never be stored or used in the same room or area containing a gas water heater or other open flame or spark-producing appliance.

REMEMBER: Flammable vapors may be drawn to this water heater from other areas of the structure by air currents.

NOTE: HEATER SHALL BE LOCATED OR PROTECTED

SO IT IS NOT SUBJECT TO PHYSICAL DAMAGE BY

the gas valve inlet. Make certain that no pipe dope has become lodged in the inlet screen of the gas valve. This will restrict the flow of gas. When attachment of gas piping to gas valve inlet is made, extreme care must be taken to prevent pipe dope from entering the gas valve inlet and to avoid excessive torque to prevent cracking of the gas valve inlet housing. The suggested maximum torque is 31.5

ft. Ibs. The manufacturer of this water heater will not be liable for any damage or injury caused as a result of a cracked gas inlet from excessive torque.

After completing all gas connections, check each gas connection and fitting for leaks. Use a soap and water solution or a commercial leak detector fluid. NEVER USE MATCHES OR OPEN FLAME WHEN

CHECKING FOR GAS LEAKS.

The water heater and its individual gas shut off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (14”

W.C.) or 3.5 kPa.

The water heater must 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 psig (14” W.C.) or 3.5 kPa.

If the gas valve is subjected to pressure exceeding 1/2 psig, the damage to the gas valve could result in an extremely hazardous condition. If this has occurred, the gas valve must be replaced contact your dealer for service. It is recommended that all service work be done by qualified service agency.

INSTALLATION SAFETY WARNING

L. P. UNITS: Liquefied petroleum (L.P.) gas is heavier than air and will remain at floor level if there is a leak. Basements, crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting, sniff at floor level. IF

YOU SMELL GAS, follow applicable instructions on the front cover or on Page 8. DO NOT OPERATE APPLIANCE UNTIL LEAKAGE IS

CORRECTED.

The water heater must be connected to the chimney. The vent pipe from the heater to the chimney (vent connector) must be no less than the diameter of the drafthood outlet on the heater and should slope upward to the chimney at least 1/4 inch per linear foot. (Figure 6).

Due to great variances in installations, unforeseeable by the manufacturer of the water heater, increased size vent connectors and pipes may be necessary for proper venting. Consult your local utility. They will aid you in determining the proper venting for your heater from the vent tables in the American National Standards

Z223.1 (NFPA 54) “National Fuel Gas Code.”

Drafthood: If you are replacing an old heater be sure to use the new drafthood supplied with the new heater. Secure drafthood in place with screw provided.

GAS PIPING INSTALLATION

All piping must comply with local and state ordinances or with the

National Fuel Gas code ANSI Z223.1 (NFPA 54), whichever applies.

Use clean black iron pipe or equivalent material approved by local codes and ordinances for gas piping. Install a ground-joint-union in the supply line as close to the water heater as possible. A manual gas shut-off valve should be at least 5 feet above floor level and readily accessible. A drip leg (consisting of a pipe tee, 4 inch nipple, and a cap) should be installed as shown in Figure 6.

Make sure the gas supplied to the heater is the same type as listed on the rating plate. DO NOT ATTEMPT TO USE THIS WATER HEATER

WITH ANY GAS OTHER THAN THE TYPE LISTED ON THE RATING

TEMPERATURE AND

PRESSURE RELIEF VALVE

For protection against excessive pressures and/or temperatures, a temperature and pressure relief valve must be installed in the opening marked, “temperature and pressure relief valve” a design certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials, as meeting the requirements for Relief Valves and Automatic Gas Shut-Off

Devices for Hot Water Supply Systems,Z21.22. Pressure rating of the valve must not exceed the working pressure shown on the data plate of the water heater.

Relief piping must terminate 6 inches above a floor drain or external to the building. Do not thread, cap, or plug the end of this discharge line. Be certain that no contact is made with any live electrical part.

Do not connect discharge line directly to drain. (Figure 6).

To prevent bodily injury, hazard to life or damage to property, the relief valve must be allowed to discharge water in the event of excessive temperature or pressure developing in the water heater. The function of the temperature and pressure relief valve is to discharge water in large quantities should circumstances demand. If the discharge pipe is not directed to the drain as shown in Figure 6 or other suitable means, the water flow may cause property damage.

130931 Rev April ʻ07

The discharge line:

(1) Must not be smaller than the pipe size of the relief valve,

(2) Must not be plugged or blocked,

(3) Must be of material capable of withstanding 210°F without distortion,

(4) Must be installed so as to allow complete drainage of both the temperature and pressure relief valve and discharge line,

(5) Must terminate at an adequate drain,

(6) Must not have any valve between the relief valve and the heater.

Failure to install and maintain a new properly listed temperature and pressure relief valve will release the manufacturer from any claims which might result from excessive temperature or water pressure.

MANUAL RELIEF LEVER

DISCHARGE LINE TO DRAIN

WARNING

Do not attempt to operate this water heater with cold water inlet valve closed. Manually operate the temperature and pressure relief valve at least once a year. To prevent water damage, discharge line must terminate at an adequate drain. Standing clear of the outlet

(discharge water may be hot), lift and release the lever handle on the temperature and pressure relief valve to make the valve operate freely.

If the heater is installed in a closed system, the temperature and pressure relief valve may drip at times. If the temperature and pressure relief valve discharges a full stream of water, have the system checked. See “Pressure Build-Up in Water System”.

If the temperature and pressure relief valve on the appliance discharges periodically, this may be due to thermal expansion in a closed water supply system (see “Pressure Build-Up in Water

System”). Contact the water supplier of local plumbing inspector on how to correct this situation. Do not plug the temperature and pressure relief valve.

DO NOT use this water heater as a replacement for an existing boiler installation.

DO NOT use with piping that has been treated with chromates, boiler seal or other chemicals.

DO NOT add boiler treatment or any chemicals to any heat piping, since the piping contains potable water.

DO NOT use with ferrous piping. The system should be installed only with new piping that is suitable for potable water, such as copper or polybutylene. DO NOT use with

PVC piping.

DO NOT use any pumps, valves, or fittings that are not com-pletely compatible with potable water piping.

DO NOT use valves that may cause excessive restriction to water flow. USE FULL FLOW BALL OR GATE VALVES

ONLY.

DO NOT tamper with the thermostat, gas valve, ignitor control or temperature and pressure relief valve. Tampering with any of these components is DANGEROUS and can result in property damage or severe injury. Tampering voids all warranties. Only qualified personnel should service these components.

DO NOT use 50/50 solder in potable water lines.

IF THE S PACE HEATING system requires water temperature in excess of 120°F, a mixing valve or other means should be installed in the domestic (potable) hot water supply to limit the RISK OF SCALD DAMAGE. (See Figure 6)

S OME JURl S Dl CTl ONS may require a backflow preventer in the incoming cold water line to the water heater.

In such cases, the temperature and pressure relief valve on the water heater may weep or relieve due to expansion of the heated water.

A diaphragm-type expansion tank (such as TACO or

EXTROL) will normally eliminate this weeping condition.

Please read and follow the manufacturer’s instructions for installation of such tanks.

COMBINATION SPACE HEATING /

POTABLE WATER HEATING SYSTEM

If this water heater is to be used to supply both space heating and domestic potable (drinking) water heating, the instructions listed below must be followed. Be sure to follow manual(s) shipped with air handler system.

Toxic chemicals, such as those used for boiler treatment, shall

NEVER

be introduced into this system.

This unit may

NEVER

be connected to any existing heating system or component(s) previously used with a non-potable water heating appliance.

WATER PIPING

Pipes and fittings should be installed in compliance with the installation drawing. Check for dip tube in cold water fitting before connection of hot and cold water lines. If the indoor installation area is subject to freezing temperatures, water piping must be protected. The water heater should be drained if being shut down during freezing temperatures.

Have the installer show you where the cold water inlet valve for the water heater is installed so that you know where and how to shut the water off. It is recommended that such a valve be located in close proximity to the cold water inlet of the water heater. See installation drawing, Figure 6.

Connect the cold water supply to the fitting marked “C” cold, the hot water outlet to the fitting marked “H” hot. Do not apply heat to either of these fittings. If sweat connections are used, sweat tubing to the adaptor before fitting adaptor to the cold and hot water fittings. It is imperative that no heat be applied to the water

130931 Rev April ʻ07

heater fittings as they may contain nonmetallic parts. When making these connections, always use a good grade of pipe joint compound and be certain that all fittings are drawn up tight (See Figure 6 for proper installation).

After piping has been installed allow tank to fill with water and check connections for leaks. To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet until a constant flow of water is obtained.

CAUTION

OPERATING AN EMPTY OR PARTIALLY FILLED WATER

HEATER WILL RESULT IN DAMAGE TO THE TANK.

SOLAR INSTALLATION

When this appliance is used AS A SOLAR STORAGE

HEATER OR AS A BACKUP FOR THE SOLAR SYSTEM, the following warning applies.

WARNING

Water supply to this heater must not exceed 180°F. Water temperature in excess of 180°F will cause the high limit control to function or open and shut off gas supply. The high limit control is a single use type that will require the replacement of the thermostat before the burner can operate. If the water supply from the solar system is above

120°F, a tempering valve or temperature limiting valves must be installed in the water supply line to limit the supply temperature to 120°F .

CHEMICAL VAPOR CORROSION

The water heater should not be installed near an air supply containing halogenated hydrocarbons. Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical vapors. Beauty shops, dry cleaning establishments, photo processing labs, storage areas of liquid and powdered bleaches, swimming pool chemicals, spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, calcium and sodium chloride, waxes and process chemicals are typical locations and compounds which are potentially corrosive. These materials are corrosive at very low concentration levels with little or not odor to reveal their presence. Products of this sort should not be stored near the water heater. Air which is brought in contact with the water heater should not contain any of these chemicals. If necessary, uncontaminated air should be obtained from remote or outside sources. NOTE: Contaminated air may cause and orange colored flame.

INSULATION BLANKET

CAUTION

Insulation blanket kits which are available for external applications to water heaters are not recommended. However, some governing bodies require their use in new construction of additions, regardless of how efficient the water heater may be.

If an insulation blanket is applied to this heater CAUTION must be exercised not to restrict the proper function of the heater. The manufacturer of this heater will not be liable for

7 incidents arising or resulting from the use of external insulation blankets. The manufacturer will not be liable for corrosion of parts which may have resulted from the use of such insulation blankets.

(1) The space between the base and the floor on a gas water heater is necessary for proper air flow. This space must be maintained unobstructed. As time passes, the blanket may sag causing an obstruction of this air passage, resulting in an unsafe operating condition.

(2) Do not apply insulation to the top of a gas water heater.

This will affect the operation of the draft hood, resulting in an unsafe operating condition.

(3) Do not cover any access panels leading to burner compartments, thermostat(s) control, doors, or temperature

&pressure relief valve on the water heater.

(4) Do not cover any labels or instruction material applied to this water heater. These safety labels and instruction material must remain on the water heater and be visible for reference by the user. Do not attempt to remove these labels, as they are a permanent part of this water heater as required by Certification

Agencies and/or the Federal Government.

Whenever the heater is filled with cold water or hot water is drawn from a faucet there will be a certain amount of condensation formed while the burner is “ON”. Moisture from the products or combustion condenses on the cooler tank surfaces and forms drops of water which may fall onto the burner or other hot surfaces to produce a “sizzling” or “frying” noise. Condensation is normal and should not be confused with a leaking tank.

The water from condensation will be noted at different times of the year in varying quantities. This condensation may spill out of the collector pan onto the floor. Do not confuse this with a leak. Once the water inside of the heater reaches a temperature of 120°F, the condensation will stop. Operating the water heater at the lowest thermostat temperature setting can keep the water heater in the condensation mode. Adjusting the thermostat setting slightly higher will overcome this problem. There is hot water scald potential however if thermostat is set too high.

NATURAL GAS MODELS

IF YOU S MELL GAS :

1. Open windows.

2. Get all people out of building.

3. DO NOT light matches. Do not smoke.

4. DO NOT touch electrical switches (on or off).

5. Extinguish any open flames.

6. Shut off gas at manual shut-off valve.

OUT OF FUEL

When your L.P. tank runs out of fuel, turn off gas at all gas appliances including gas to pilots. After L.P. tank is refilled, all appliances must be re-lit according to the manufacturer’s instructions.

WARNING

8

HYDROGEN GAS

Hydrogen gas can be produced in a water system that has not been used for a long period of time (generally two weeks or more).

HYDROGEN GAS IS EXTREMELY

FLAMMABLE.

To prevent the possibility of injury under these conditions, we recommend the hot water faucet be open for several minutes at the kitchen sink before you use any electrical appliance which is connected to the hot water system. Do not light a cigarette, cigar or pipe. Do not smoke. If hydrogen is present, there will probably be an unusual sound such as air escaping through the faucet, as the water begins to flow. Remember no smoking or open flame near the faucet at the time it is opened.

EXPOSURE TO WATER

Do not use this appliance if any part has been under water.

Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

TEMPERATURE ADJUSTMENT

The temperature selector dial has been adjusted to its lowest setting when shipped from the factory.

For energy-efficient operation of your water heater, the recommended temperature setting is approximately 1 30°F.

Households with small children or invalids may require a 120°

F or lower temperature setting to reduce the risk of scald injury. Some states require a lower temperature setting. Check with your gas supplier for local requirements governing the temperature setting. NOTE: The lower the temperature setting the greater the energy efficiency, both to heat water and to maintain its temperature during standby periods. Lower water temperatures also extend the tank life. Remember, no water heating system will provide exact temperatures at all times.

Allow a few days of operation at this setting to determine the correct temperature setting consistent with your needs. NOTE:

This water heater, when set at the lower temperature setting, is not capable of producing hot water of sufficient temperature for sanitizing purposes.

During winter season or any cold period, you may desire a higher temperature setting to adjust for the colder incoming water. However, this adjustment may cause additional condensation to form on the cooler tank surface. This does not mean the tank is leaking. Refer to Page 8 for explanation of this condition. During the summer months, the warmer incoming water temperatures will benefit the performance of your water heater and reduce the amount of condensation developed.

Condensation does not mean that your tank is leaking. Over

40% of reported tank leaks on installation are proven to be condensation. To avoid unnecessary inconvenience and expense, make sure the tank is leaking before calling a service person.

CAUTION: Setting the temperature selector dial higher provides hotter water, which increases the risk of scald injury.

The water heater thermostat is constructed with a built-in shutoff designed to shut off the gas supply to the main Burner and pilot Burner in the event the pilot flame is extinguished for any reason. The thermostat is also equipped with a high temperature limit switch ECO (Energy Cut Off). The Energy

Cut Off will shut off all gas supplied to the Burner and pilot

Burner in the event the water temperature exceeds 180°F. The

Energy Cut Off switch is a single use switch and is not field replaceable. Should the Energy Cut Off function (open), the thermostat must be replaced before the water heater can be placed in operation again.

VACATION/FREEZING TEMPERATURES

__

If the water heater is to remain idle for 30 days or more, or is subject to freezing temperatures while shut off, the water heater and piping should be drained (refer to Page 12), and the drain valve should be left open. Refer to Hydrogen Gas Warning (Page 8).

GAS PRES S URE

__

With the water heater in operation

(main burner on), the maximum supply pressure must not exceed the specified value below, and the minimum supply and normal manifold gas pressures are as follows:

S upply Pressure Manifold

Pressure

MAX. MIN. NORMAL

Natural Gas: 10.5” W.C. 5” W.C. 4” W.C. - 4.7” W.C.

(see rating plate)

L.P. Gas: 13.0” W.C. 11” W.C. 10” W.C.

11

Some models have values higher or lower than those noted above. Refer to pressure noted on the label affixed to the front of the water heater. Consult your local gas company or gas supplier if correction is necessary.

BURNER ADJUSTMENT

There are no adjustments to this water heater (other than water temperature selection). The thermostat (gas control valve) is equipped for total regulation of the main burner and pilot gas pressures.

WARNING

Only qualified personnel should adjust the pressure regulator.

BURNER MAINTENANCE

At least once every three months visually check burner and pilot flames and compare with the sketches below.

Observation of the gas flame should show the burner flame to be a soft blue with the suggestion of slight yellow tips. A flame of too light of a color may not be a carbonizing flame and should be avoided. If this is suspected, turn the control to the off position, allow combustion chamber to cool, and check the top of the combustion chamber and burner for soot deposits. If soot exists, clean the burner with soap and water.

If continued sooting occurs, refer to Trouble Symptoms,

Pages 14 and 15.

EMERGENCY SHUT DOWN

WARNING

M A I N BU R N E R

THERMOCOUPLE AND/OR

PILOT REPLACEMENT

1. Remove burner assembly. (See “REMOVAL OF BURNER

ASSEMBLY” section.)

2. Grasp the thermocouple line and moderately pull the thermocouple from the pilot burner assembly. NOTE: If for any reason the thermocouple will not disengage from the pilot bracket assembly, replace the complete pilot assembly, follow steps 4 and 5, otherwise go to next step.

3. Push replacement thermocouple through hole in pilot bracket until it snaps in place. The end of a properly installed thermocouple should extend approximately 1/4 inch past the tip of the pilot assembly (Go to step 6).

4. Remove No. 8-32 screw holding pilot assembly and pilot shield (if provided) to main burner (Figure 8, Page 16).

5. Re-install replacement pilot assembly to main burner making sure that pilot shield (if provided) is in the right location. (Figure 8, Page 16).

6. Replace burner assembly (See “REPLACING THE

BURNER ASSEMBLY” section).

REMOVAL OF THE BURNER ASSEMBLY

For your safety the following procedure should be performed by qualified service personnel or someone familiar with gas appliances, as it involves disconnection of gas piping and leak testing .

1. Turn gas control knob clockwise to “OFF” position. (Page

9 or 10).

2. Open outer and inner doors.

3. Disconnect the thermocouple, pilot tube, and manifold tube at the thermostat (Figure 7). Note that the propane

(LPG) manifold has left hand thread rotation.

4. Remove the burner spreader by removing the nuts on top of the spreader.

5. Pull the burner toward the front until the holding bracket slides out of the slot in the bottom pan. If the burner is dirty or clogged it cab be cleaned with soap and water.

DRAINING AND FLUSHING

INTERIOR OF TANK

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 OFF GAS TO APPLIANCE.” (Figure 6)

2. Close the cold water inlet valve to the heater (Figure 6).

3. Open a nearby hot water faucet.

4. Open the heater drain valve. (Figure 6).

REPLACING THE BURNER ASSEMBLY

1. Insert the burner assembly into the opening in the bottom pan and slide toward the rear so that the burner holding bracket slides into the slot in the bottom pan. Reinsert the spreader on to the burner post and replace the two nuts.

2. The manifold tube will now line up to the thermostat connection.

3. Reconnect the manifold tube and pilot tube. Do not cross thread these fittings (Figure 7) . Note that the propane

(LPG) manifold has left hand thread rotation.

4. Reconnect the thermocouple.The thermocouple nut should be started and turned all the way in by hand. An additional one-quarter turn with a 3/8” open end wrench will be sufficient to set the lockwasher (Figure 7).

CAUTION: OVERTIGHTENING MAY DAMAGE

THE THERMOCOUPLE OR THERMOS TAT.

5. Follow Lighting Instructions to relight water heater.

6. Check for gas leaks with soap and water solution (soap suds) or liquid detergent. Bubble forming indicates a leak.

FIX ALL LEAKS IMMEDIATELY.

WARNING

DO NOT US E OPEN FLAME OR ANY KIND OF

S PARK TO CHECK FOR LEAKS .

WARNING

THIS WATER CAN BE HOT.

5. If the heater is going to be shut down and drained for an extended period, the drain valve should be left open. Refer to “Hydrogen Gas” warning, Page 8.

6. To start heater again, read paragraph “Operation” and

“LIGHTING INSTRUCTIONS”.

VENTING SYSTEM INSPECTION

Check the draft hood relief opening (Figure 6) using a match flame after 15 minutes of operation. Pass the match flame around the relief opening of the draft hood. A steady flame drawn into the opening indicates proper draft. If the flame flutters or is blown out this would indicate spillage and corrective action must be made to the vent. (Figure 6).

At least every 3 months a visual inspection should be made of the venting system. You should look for:

• Obstructions which cause improper venting.

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

12

TAMPERING

Tampering with the thermostat, gas valve, pilot, burner, or temperature and pressure relief valve is DANGEROUS and voids all warranties. Only qualified personnel should service these components.

130931 Rev April ʻ07

ANODE

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

Parts section) for protection of the tank. Certain water conditions will cause a reaction between this rod and the water.

This is defined as smelly water and removal of the rod will void any warranties stated or implied. The parts list includes a special anode that can be ordered if odor and/or discoloration occur. However, this rod is only good to a certain point, after which, we can only suggest that a water conditioning company be contacted to supply filtration equipment.
