DANGER!
WATER TEMPERATURE SEITING
Safety and energy conservation are factors to be considered when selecting the water temperature setting of a water heater’s gas control. Water temperatures above 125F 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 recommended for reducing point of use water temperature by mixing bot and cold water in branch water lines. It is recommended that a mixing valve complying with the Standard for Temperature Actuated Mixing Valves for Hot Water Distribution Systems, ASSE 1017 be installed. See pages 18 & 19 for more details and contact a licensed plumber or the local plumbing authority for further information.

Time/Temperature Relationship in Scalds

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 120F or lower gas control (thermostat) setting to prevent contact with “HOT  water. Maximum water temperatures occur just after the burner has shut off. To find the water temperature being delivered, tum on a hot water faucet and place a thermometer in the water stream and read the thermometer. (See pages 18 and 19 for more details.) 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 gas control(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!
LIQUEFIED PETROLEUM (LP – PROPANE OR BUTANE) AND NATURAL GAS MODELS
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.

• Water heaters utilizing LP gas are different from natural gas models. A natural gas water heater will not function safely on LP gas and vice versa.

• No attempt should ever be made to convert the water heater from natural gas to LP gas. To avoid possible equipment damage, personal injury, or fire, DO NOT connect the water heater to a fuel type, not in accordance with the unit data plate. LP for LP units. Natural as for natural gas units. These units are not certified for any other fuel type.

• LP appliances should not be installed below grade (for example, in a basement) if such installation is prohibited by federal, state, and/or local laws, rules, regulations, or customs.

• 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 a gas leak, be sure to sniff near the floor also.

• Gas detectors are recommended in LP & natural gas applications and their installation should be in accordance with the detector 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, etc., be used to detect leaks in 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.

WARNING!
For your safety, the Information In this manual must be followed to minimize the risk of fire or explosion, electric shock, or to prevent property damage, personal injury, or loss of life.

SAVE THESE INSTRUCTIONS

Installing the water heater.

This water beater must be installed in accordance with these instructions, local codes, utility company requirements, and/or in the absence of local codes, use the latest edition  of the American National Standard/National Fuel Gas Code. A copy can be purchased from either the American Gas Association, 400 N. Capitol Street NW, Washington, DC  20001 as ANSI standard Z223.1 or National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269 as booklet NFPA 54.

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.

Location

The water heater should not be located in an area where leakage from the tank or connections wiU result in damage to the area adjacent to the heater or to lower floors of the structure.
When such areas cannot be avoided it is recommended that a suitable drain pan, adequately drained, must be installed under the water heater. The pan must not restrict air flow to the combustion air inlet openings (perforation openings) located around the lower perimeter of the water heater.
Drain pan kits are available from the store where the water heater was purchased, or any water heater distributor.
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.
A gas-fired water heater or any other appliance should not be installed in a space where liquids that give off flammable vapors are to be used or stored. Such liquids include gasoline, LP gas (butane or propane), paint or adhesives, and their thinners, solvents, or removers.
When installed in a closet, DO NOT block or obstruct any of the combustion air inlet openings located around the perimeter of the water heater. A minimum of I” is required between these combustion air inlet openings and any obstruction.
Because of natural air movement in a room or other enclosed space, flammable vapors can be carried some distance from where liquids that give off flammable vapors are to be used or stored. The open flame of the water heater’s pilot or main burner can ignite these vapors and create a shutdown condition of the water heater which will not allow the water heater to ignite until examined by a Qualified Service Technician.
FVIR certified gas water heaters can be installed on a residential garage floor without the use of an 18-inch stand in accordance with the National Fuel Gas Code, NFPA 54,  ANSI Z223. I unless otherwise directed by State and Local code requirements. The water heater must be located so it is not subject to physical damage, for example, by moving vehicles, area flooding, etc

• The water heater should be installed as close as practical to the gas vent or chimney.
• Long hot water lines should be insulated to conserve water and energy.
• The water heater and water lines should be protected from exposure to freezing temperatures.
• DO NOT install the water heater in bathrooms, bedrooms, any occupied rooms normally kept closed, or in unprotected outdoor areas.
• Minimum clearance from combustible construction:

“Front” clearance dimension is measured from the gas control (thermostat) to the closet door.
“Top” clearance dimension is measured from the jacket top to the ceiling.

• If the clearances stated on the Instruction/Warning Label, located on the front of the heater differ, install the water heater according to the clearances stated on the label.
• If the water heater is installed in an alcove or closet, the entire floor must be covered by a wood or metal panel. minimum of 24″ clearance from the front and top should be available for adequate inspection and servicing.
• The water heater may be installed on combustible floors, but not directly on carpeting. If the water heater must be installed on carpeting, place a metal or wood panel beneath the water heater, extending beyond its full width and depth at least S” in all directions.

NOTICE: For proper operation and maintenance, a minimum clearance of 1.S inches must be provided from the combination temperature and pressure relief valve to any wall or object.

Inspect Shipment
Inspect the water heater for possible damage. Check the markings .on the rating plate of the water heater to be certain the type of gas supplied corresponds to the water heater requirements.

Combustion and Ventilation Air
Proper operation of the water heater requires air for combustion and ventilation. Provisions for combustion and ventilation air must comply with referenced codes and standards.
When installed in a closet, DO NOT block or obstruct any of the combustion air inlet openings located around the perimeter of the water heater. A minimum of 1″ is required between these combustion air inlet openings and any obstruction.
NOTICE: If the water heater is installed in an unconfined space within a building of conventional frame, masonry or metal construction, infiltration air is normally adequate for proper combustion and ventilation. If the water heater is installed in a confined space, provisions for combustion and ventilation air must be made.
A confined space is one having a volume of less than 50 cubic feet per I 000 Btuh of the aggregate input of all appliances within that space.
The air must be supplied through two permanent openings of equal area. One is to be located within 12 above the floor and the other is to be located within 12″ from the ceiling.
The minimum net free area of each opening must not be less than one square inch per 1000 Btuh of the total input rating of all the appliances in the enclosure (but not less than 100 square inches), if each opening communicates with other unconfined areas inside the building.

Buildings of unusually tight construction shall have the combustion and ventilation air supplied from outdoors, or a freely ventilated attic or crawl space.
If air is supplied from outdoors, directly or through vertical ducts, there must be two openings located as specified above and each must have a minimum net free area of not less than one square inch per 4000 Btuh of the total input rating of all the appliances in the enclosure.
If horizontal ducts are used to communicate with the outdoors, each opening must have a minimum net free area of not less than one square inch per 2000 Btuh of the total input rating of all the appliances in the enclosure. If ducts are used, the minimum dimensions of rectangular air ducts shall not be less than 3°.

NOTICE: If the duct openings which supply combustion and ventilation air are to be covered with a protective screen or grill, the net-free area (openings in the material) of the covering material must be used in determining the size of the openings. Protective screening for the openings MUST NOT be smaller than 1/4mesh to prevent clogging by lint or other debris.
NOTICE: The water heater should not be installed near an air supply containing halogenated hydrocarbons.

Corrosive Atmospheres
The air in beauty shops, dry cleaning establishments, photo processing labs, and storage areas for liquid and powdered bleaches or swimming pool chemicals often contain such halogenated hydrocarbons.
An air supply containing halogenated hydrocarbons may be safe to breathe, but when it passes through a gas flame corrosive elements are released that will shorten the life of any gas burning appliance.
Propellants from common spray cans or gas leaks from A/C and refrigeration equipment are highly corrosive after passing through a flame.
The water heater warranty is voided when failure of the heater is due to operation in a corrosive atmosphere.

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 backflow 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 backflow 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 that 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.

IMPORTANT: DO NOT apply beat to the HOT or COLD water connections. If sweat connections are used, sweat tubing to the adapter before fitting the adapter to the cold water connections on the beater. Any beat applied to the cold water supply fittings will permanently damage the dip tube.

Water Supply Connections

Refer to the illustration below for a 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.

Typical Installation

A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves 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. The 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: The tank must be full of water before the beater is turned on. The water beater 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 the 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.
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.

WARNING: DO NOT attempt to convert this water heater for use with a different type of gas other than the type shown on the rating plate. Such conversion could result in hazardous operating conditions.

Gas Supply

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.
The National Fuel Gas Code (NFGC) mandates a manual gas shut-off valve: See (NFGC) for complete instructions.
If flexible connectors are used, the maximum length shall not exceed 36.
If lever-type gas shut-offs are used, they shall be T-Handle type.
The 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.

Where a sediment trap is not incorporated as part of the appliance, a sediment trap shall be installed downstream of the equipment shutoff valve as close to the inlet of the appliance as practical at the time of the appliance installation. The sediment trap shall be either a tee fitting with a capped nipple in the bottom outlet or another device recognized as an effective sediment trap. DO NOT use excessive force (over 31.5 f·lbs.) in tightening the pipe joint at the gas control (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 gas, or 14″ w.c. for LP gas. For purposes of input adjustment, the minimum inlet gas pressure (with the 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.
WARNING: Never use an open flame to test for gas leaks, as property damage, personal injury, 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.

• Tum 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 gas control (thermostat) should also be leak tested after the water heater is placed in operation.

Pressure Testing the Gas Supply System
The appliance and its individual shutoff 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 psi (3.5 kPa).
The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psi (3.5 kPa).

High Altitude
This water heater is suitable and certified for use at high altitudes. Refer to the altitude label on the water heater for the maximum allowable installation altitude.
WARNING: Installations above the rated altitude as specified on the altitude label are not authorized and may result in improper and inefficient operation of the appliance,  producing carbon monoxide gas in excess of acceptable limits, which could result in serious injury or death.

The water heater must be Installed with the factory-supplied draft hood in place.

DANGER: Failure to install the draft hood and properly vent the water beater to the outdoors as outlined in the Venting section of this manual will result in unsafe operation of the water beater causing bodily injury, explosion, fire, or death. To avoid the risk of fire, explosion, or asphyxiation from carbon monoxide, NEVER operate the water beater unless it is properly vented and has an adequate air supply for proper operation as outlined in the Venting section of this manual.

Venting
This water heater is a Category I- Natural Draft appliance. Vent connectors must be attached to the draft hood outlet to connect the water heater to the gas vent or chimney.  The vent connectors must be the same size (diameter) as the draft hood or larger, never smaller.
For proper venting in certain installations, a larger vent connector size may be needed. Consult the Vent Tables in Appendix G of the latest version of the National Fuel Gas  Code (ANSI standard Z223.1 or NFPA 54).
Multi-story and common venting is permitted, consult the latest version of the National Fuel Gas Code (ANSI Z233.1/NFPA 54).
Horizontal vent connectors must be pitched upward to the chimney at least 1/4″ per foot of length. Single wall vent connectors must be at least 6″ from the adjacent unprotected combustible surface.
Vent joints must be securely fastened by sheet metal screws or other approved methods.
Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use a flame of a match or candle or smoke. The flame or smoke should be pulled into the draft hood’s relief opening(s).
WARNING: If local codes require external application of insulation blanket kits the manufacturer’s instructions included with the kit must be carefully followed.

Insulation Blankets

Insulation blankets, available to the general public, for external use on gas water heaters, are not necessary. The purpose of an insulation blanket is to reduce the standby beat loss encountered with storage tank heaters. This water heater meets or exceeds the National Appliance Energy Conservation Act standards with respect to insulation and standby loss requirements making an insulation blanket unnecessary.
The manufacturer’s warranty does not cover any damage or defect caused by installation, attachment, or use of any type of energy saving or other unapproved devices ( other than those authorized by the manufacturer) into, onto, or in conjunction with the water heater. The use of unauthorized energy- saving devices may shorten the life of the water heater and may endanger life and property.
The manufacturer disclaims any responsibility for such loss or injury resulting from the use of such unauthorized devices.

CAUTION: If local codes require the application of an external insulation blanket to this water beater, pay careful attention to the following so as not to restrict the  proper function and operation of the water beater:

• DO NOT cover the operating or warning labels attached to the water heater or attempt to relocate them on the exterior of the insulation blanket.
• DO NOT apply insulation to the top of the water heater. This will interfere with the safe operation of the draft hood.
• DO NOT cover the burner access door, jacket door, gas control (thermostat)/gas valve, or pressure and temperature relief valve.
• DO NOT apply insulation to the bottom of the water heater or the area where the combustion air inlet openings are located. This area must be unobstructed so as not to restrict combustion air flow to the burner.
• Inspect the insulation blanket frequently making certain it has not sagged and is restricting the airflow to the combustion air inlet openings (perforation holes) located around the lower perimeter of the water heater jacket. This could result in an unsafe operating condition.

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 the 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 tum off the manual gas shut-off valve if water beater has been subjected to overheating, fire, flood, physical damage or if the gas supply fails to shut off.

• DO NOT tum on the water beater unless it is completely filled with water.

• DO NOT tum on the water beater if the cold water supply shut-off valve is closed.

• DO NOT allow combustible materials such as newspaper, rags, or mops to accumulate near the water beater.

• DO NOT store or use gasoline or other flammable vapors and liquids, such as adhesives or paint thinner, in the vicinity of this or any other appliance. f such flammables must be used, open doors and windows for ventilation, and all gas burning appliances in the vicinity should be shut off including their pilot burners, to avoid vapors lighting.
  NOTICE: Flammable vapors can be drawn by air currents from surrounding areas to the water heater.

• 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.

Water Temperature Setting

DANGER: Hotter water increases the potential for Hot Water SCALDS. Households with small children, disabled, or elderly persons may require a 120F or lower gas control (thermostat)  setting to prevent contact with HOT water.
The temperature of the water in the water heater can be regulated by setting the temperature dial on the front of the gas control (thermostat).
Safety and energy conservation are factors to be considered when selecting the water temperature setting of the water beater’s gas control (thermostat(s)). The lower the temperature setting, the greater the savings in energy and operating costs.
To comply with safety regulations, the gas control (thermostat) was set at its lowest setting before the water heater was shipped from the factory. The recommended starting point temperature is 120F.

Water temperatures above 125F can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined in this manual and on the label located on the water beater near the gas control thermostat.
Mixing valves are recommended for reducing the point of use water temperature by mixing hot and cold water in branch water lines. It is recommended that a mixing valve complying with the Standard for  Temperature Actuated Mixing Valves for Hot Water Distribution Systems, ASSE 1017 be installed. See page 4 for more details and contact a licensed plumber or the local plumbing authority for further information.
The chart below may be used as a guide in determining the proper water temperature for your home.

Time/Temperature Relationship in Scalds.

Water Temperature Setting

Maximum water temperatures occur just after the burner has shut off. To determine the water temperature, turn on a hot water faucet and place a thermometer in the water stream.
The reference mark A on the rim of the temperature dial represents an approximate water temperature of 120F(49° C).
The reference mark ▲represents an approximate water temperature of 130F (54° C).
Each reference mark above or below these points indicates an approximate change of 10F (5.5° C).
To adjust the temperature, tum the temperature dial to an initial setting of 120F (49° C).
A condition is 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 (shut-oft) valve, and DO NOT operate the water heater again until it has been checked by a qualified service technician.
NOTICE: DO NOT use this appliance if any part has been under water. Immediately call a qualified installer or service agency to replace a flooded water heater. DO NOT attempt to repair the unit! It must be replaced.

Care and cleaning of the water heater

Draining the Water Heater
CAUTION: Shut off gas to the water heater at the gas control (thermostat) gas cock or the manual shut-off valve before draining water.
DANGER: Before manually operating the temperature and pressure 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, tum 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 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: Hotter water increases the potential for Hot Water Scalds.
DANGER: Failure to perform the recommended Routine Preventative Maintenance can harm the proper operation of this water heater, which can cause carbon monoxide dangers, excessively hot water temperatures, and other potentially hazardous conditions.

Routine Preventative Maintenance

Properly maintained, your water heater will provide years of dependable trouble­ free service.
It is recommended that a periodic inspection of the gas control (thermostat), burner, relief valve, and venting system should be made by service personnel qualified in gas appliance repair.
It is suggested that a routine preventative maintenance program be established and followed by the user.
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 settling basin for solids suspended in the water. It is therefore not uncommon for hard water deposits to accumulate in the bottom of the tank. If allowed to accumulate, these solids can cover the gas control (thermostat) sensors, causing the sensors to operate erratically. Because accumulated solids can prevent the gas control (thermostat) sensors from accurately reading the water temperature, the water at the fixture can be hotter than the gas control (thermostat) dial setting. 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 the anode rod.
This water heater incorporates a combustion shut-off device that shuts the operation of the water heater down if undesirable combustion conditions occur.
Such as the presence of flammable vapors or blockage of the combustion air inlet openings. Please contact a Qualified Service Technician if this occurs.

Housekeeping

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

Visually inspect pilot burner and relight if necessary.
To ensure sufficient ventilation and combustion air supply, proper clearances must be maintained.
When installed in a closet, DO NOT block or obstruct any of the combustion air inlet openings located around the perimeter of the water heater. A minimum of 1 is required between these combustion air inlet openings and any obstruction.

Venting System Inspection
Inspect the gas venting system and the chimney.
Make certain the vent connector from the draft hood to the chimney is properly positioned and securely attached. If after inspection of the vent system you found soot or deterioration; call the local gas utility to correct the problem and clean the flue, or replace the flue, flue baffle, and venting system before resuming the 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 pilot burner and main burners annually.
Through the sight 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.
CAUTION: For your safety, cleaning of the burner must be performed only by qualified service personnel. The burner chamber is a sealed area, If the burner access door is removed, the burner access door gasket must be replaced.
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.

Vacation and Extended Shut-Down

NOTICE: Refer to the Hydrogen Gas Caution in the Operating Instructions.
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.
The water heater and piping should be drained if they might be subjected to freezing temperatures.
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.

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 greatly shorten the life of the glass-lined tank and will exclude warranty coverage.
This water heater is equipped with an anode rod designed to prolong the life of the glass-lined tank. The anode rod is slowly consumed, thereby eliminating or minimizing corrosion of the glass-lined tank.
Water sometimes contains a high sulfate and/or mineral content and together with the cathodic protection process can produce hydrogen sulfide or rotten egg odor in the heated water. Chlorination of the water supply should minimize the problem.
