General Safety

WARNING

WATER HEATERS EQUIPPED FOR ONE TYPE GAS ONLY: This water heater is equipped for one type gas only. Check the model rating plate near the gas control valve for the correct gas. DO NOT USE THIS WATER HEATER WITH ANY GAS OTHER THAN THE ONE SHOWN ON THE MODEL RATING PLATE. Failure to use the correct gas can cause problems which can result in DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. If you have any questions or doubts consult your gas supplier or local utility.

WARNING

A fire can start if combustible materials such as clothing, cleaning materials, or flammable liquids are placed against or next to the water heater.

WARNING

INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS) ARE LIKELY TO BE PRESENT OR STORED (GARAGES, STORAGE, AND UTILITY AREAS, ETC): Flammable liquids (such as gasoline, solvents, propane (LP) or butane, etc.), all of which emit flammable vapors, may be improperly stored or used in such areas. The gas water heater ignitor or main burner can ignite such vapors. The resulting flashback and fire can cause death or serious burns to anyone in the area, as well as property damage. If installation in such areas is your only option, then the installation must be accomplished in a way that the ignitor and main burner flame are elevated from the floor at least 18 inches. While this may reduce the chances of flammable vapors from a floor spill being ignited, gasoline and other flammable substances should never be stored or used in the same room or area containing a gas water heater or other open flame or spark producing appliance. NOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.

WARNING

HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, some type of tempering device, such as a mixing valve, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturers instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual.

WARNING

BEFORE LIGHTING [PROPANE (L.P.) GAS WATER HEATERS]: Propane (L.P.) gas is heavier than air. Should there be a leak in the system, the gas will settle near the ground. Basements or crawl spaces, closets and areas below ground level will serve as pockets for the accumulation of this gas. Before attempting to operate the water heater or turning on a nearby electrical light switch, be absolutely sure there is no accumulated gas in the area. Search for odor of gas by sniffing at ground level in the vicinity of the appliance. If odor is detected, follow steps indicated at “For Your Safety” on the cover page of this manual then leave the premises.

WARNING

Improper installation, adjustment, alteration, service or maintenance can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Refer to this manual or consult your local gas utility for further assistance.

WARNING

At the time of manufacture this water heater was provided with a combination temperature-pressure relief valve 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 Shutoff Devices for Hot Water Supply Systems, and the latest edition of ANSI Z21.22 and the code requirements of ASME. If replaced, the valve must meet the requirements of local codes, but not less than a combination temperature and pressure relief valve certified as meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22 by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials. The valve must be marked with a maximum set pressure not to exceed the marked hydrostatic working pressure of the water heater (150 lbs. p.s.i.) and a discharge capacity not less than the water heater input rate as shown on the model rating plate. (Electric heaters - watts divided by 1000 x 3412 equal BTU/Hr. rate.) Your local jurisdictional authority, while mandating the use of a temperature-pressure relief valve complying with ANSI Z21.22 and ASME, may require a valve model different from the one furnished with the water heater. Compliance with such local requirements must be satisfied by the installer or end user of the water heater with a locally prescribed temperature-pressure relief valve installed in the designated opening in the water heater in place of the factory furnished valve. For safe operation of the water heater, the relief valve must not be removed from it’s designated opening or plugged. The temperature-pressure relief valve must be installed directly into the fitting of the water heater designated for the relief valve. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches above, or at any distance below the structural floor. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet, or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve. No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6″″air gap is provided. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage. The Discharge Pipe: —Must not be smaller in size than the outlet pipe size of the

valve, or have any reducing couplings or other restrictions. —Must not be plugged or blocked. —Must be of material listed for hot water distribution. —Must be installed so as to allow complete drainage of both

the temperature-pressure relief valve, and the discharge

pipe. —Must terminate at an adequate drain. —Must not have any valve between the relief valve and tank.

General Safety (cont’d)

WARNING

This water heater must not be 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 (76.2mm) in any direction, or if the appliance is installed in an alcove or closet, the entire floor must be covered by the panel. Failure to heed this warning may result in a fire hazard.

WARNING

Do not install in a confined area such as a closet, unless you provide ventilation air as shown in the “Locating The New Water Heater” section. Never obstruct the flow of ventilation air. If you have any doubts or questions at all, call your gas company. Failure to provide ventilation air can result in a fire or explosion and can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.

WARNING

If this water heater will be used in beauty shops, barber shops, cleaning establishments, or self-service laundries with dry cleaning equipment, it is imperative that the water heater or water heaters be installed so that combustion and ventilation air be taken from outside these areas. Refer to the “Locating The New Water Heater” section of this manual and also the latest edition of the National Fuel Gas Code, ANSI Z223.1, also referred to as NFPA 54 for specifics provided concerning air required.

WARNING

The power direct vent water heater requires its own (separate) venting system. It cannot be connected to an existing vent pipe or chimney. It must be terminated to the outdoors. Failure to properly install the venting system can result in asphyxiation, a fire or explosion and can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.

WARNING

No vent damper installation is compatible with this power vented water heater design. No vent damper, whether it is operated thermally or otherwise is to be installed on this power vented water heater. Alteration of any part of the factory-furnished vent assembly could result in improper operation due to restriction of flue gases, spillage of flue gases and may cause carbon monoxide poisoning.

WARNING

1. The appliance and its individual shutoff valve must be discon-

nected from the gas supply piping system during any pressure testing of the gas system at test pressures in excess of

⁄2 pound

per square inch (3.5kPa).

2. The appliance must be isolated from the gas supply piping sys-

tem by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal or less than 1⁄2 pound per square inch (3.5kPa).

WARNING

Soot build-up indicates a problem that requires correction before further use. Turn “OFF” gas to water heater and leave “OFF” until repairs are made, because failure to correct the cause of the sooting can result in a fire or explosion causing DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE.

WARNING

The water heater must be properly vented outdoors. Never operate the water heater unless it is vented to the outdoors and has adequate air supply to avoid risks of improper operation, explosion or asphyxiation.

WARNING

Vent termination must not be within 4 feet of any items such as gas meters, gas valves or other gas regulating equipment.

WARNING

Obstructed or deteriorated vent systems may present a serious health risk or asphyxiation.

WARNING

Chemical vapor corrosion of the flue and vent system may occur if air for combustion contains certain chemical vapors. Spray can propellants, cleaning solvents, refrigerator and air conditioner refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes, bleach, and process chemicals are typical compounds which are potentially corrosive.

WARNING

Minimum clearances between the water heater and combustible and non-combustible construction are: 0 inches from sides, 0 inches from back, 6 inches from front of jacket to closet door and 12 inches from top of jacket to combustible and non-combustible material. Minimum vent clearance: 0 inches. Provide 24 inches front clearance for servicing and adequate clearance between the jacket top and ceiling for servicing the flue area.

WARNING

HYDROGEN GAS: Hydrogen gas can be produced in a hot water system that has not been used for a long period of time (generally two weeks or more). Hydrogen gas is extremely flammable and explosive. To prevent the possibility of injury under these conditions, we recommend the hot water faucet be opened for several minutes at the kitchen sink before any electrical appliances which are connected to the hot water system are used (such as a dishwasher or washing machine). If hydrogen gas is present, there will probably be an unusual sound similar to air escaping through the pipe as the hot water faucet is opened. There must be no smoking or open flame near the faucet at the time it is open.

WARNING

INSULATING JACKETS: When installing an external water heater insulation jacket on a gas water heater: a. DO NOT cover the temperature-pressure relief valve. b. DO NOT put insulation over any part of the top of the gas water

heater.

c. DO NOT put insulation over the gas control valve or gas con-

trol valve/burner cover, or any access areas to the burner.

d. DO NOT let insulation around the gas water heater to get with-

in 8 inches of the floor (air must get to the burner).

e. DO NOT cover or remove operating instructions, and safety

related warning labels and materials affixed to the water heater.

Failure to heed this will result in the possibility of a fire or explosion.

WARNING

Flood damage to a water heater may not be readily visible or immediately detectible. However, over a period of time a flooded water heater will create dangerous conditions which can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Call a qualified service technician or contractor to replace a flooded water heater. Do not attempt to repair the unit! It must be replaced!

CAUTION

WATER HEATERS EVENTUALLY LEAK: Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow of water will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are available at your local hardware store. Such a drain pan must have a minimum length and width of at least 2 inches greater than the water heater dimensions and must be piped to an adequate drain. Drain pan depth must allow for access to the outer doors for servicing the ignitor and burner. Under no circumstances is the manufacturer to be held liable for any water damage in connection with this water heater.

NOTE: To protect against untimely corrosion of hot and cold water fittings, it is strongly recommended that di-electric unions or couplings be installed on this water heater when connected to copper pipe.

This appliance has been design certified as complying with American National Standard/CSA Standard for water heaters and is considered suitable for:

Water (Potable) Heating: All models are “considered suitable for water (potable) heating.” Water (Potable) Heating and Space Heating: Certain models are “considered suitable for water (potable) heating and space heating.”

Refer to the model and rating plate of the water heater.

WARNING

If this water heater is to be used for multiple location users, such as for apartments, hotels, motel, duplexes, a tempering device should be used at each point of use (sink, shower, tub, etc.) to limit the maximum temperature of the hot water to 125°F. This will help to reduce, but not eliminate the risk of scald or serious burn injury form exposure to hot water. Water at a temperature above 125°F, can cause 3rd degree burn injuries which are the most serious burns and require skin grafts and results in permanent scarring or even death. Some people are more likely to be permanently injured by hot water than others; these include the elderly, children, the infirm, or the physically/mentally handicapped. Before immersing yourself or anyone else in hot water, be sure to check the water temperature. WARNING: HOTTER WATER INCREASES THE RISK OF SCALD INJURY. (Also see “Temperature Regulation” section) Mixing valves are available at plumbing supply or hardware stores. Follow manufacturer’s instructions for installation of these valves.

Facts to Consider About the Location

You should carefully choose an indoor location for the new water heater, because the placement is a very important consideration for the safety of the occupants in the building and for the most economical use of the appliance. This water heater is not for use in manu-

factured (mobile) homes or outdoor installation.

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

1. The location selected should be indoors as close as practical to the vent termination point, and as centralized with the water piping system as possible. The water heater, as all water heaters, will eventually leak. Do not install without adequate drainage provisions where water flow will cause damage.

2. If vented through an outside wall or through the roof using 3″ vent piping, the total vent run (vertical and horizontal) cannot exceed a total of 45 feet with one elbow. If more elbows are required, the venting distance must be reduced 5 feet for every 90° elbow. See page 15 for vent chart.

3. Vent piping cannot slope downward and horizontal runs require

⁄8″ per five foot rise. All horizontal runs require adequate support

at 31⁄2 foot intervals and vertical runs supported at 5 foot intervals.

4. The water heater requires its own (separate) venting system. It cannot be connected to an existing vent pipe or chimney. It must terminate to the outdoors. Whenever possible terminate the vent on the leeward side of the building through an outside wall. Note:

Condensation may be created, at times, as the combustion gases exit the vent cap and discoloration of surfaces in proximity to the vent cap may occur.

5. The water heater comes equipped with a 7 foot power cord which can be used to connect to a 110/120 volt power source if (1) local codes allow, and (2) there is a three prong receptacle available.

Locating the New Water Heater

6. The location selection must provide adequate clearances for servicing and proper operation of the water heater.

Figure 1

WARNING

Propellants of aerosol sprays and volatile compounds, (cleaners, chlorine based chemicals, refrigerants, etc.) in addition to being highly flammable in many cases, will also change to corrosive hydrochloric acid when exposed to the combustion products of the water heater. The results can be hazardous, and also cause product failure.

WARNING

INSTALLATION IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS) ARE LIKELY TO BE PRESENT OR STORED (GARAGES, STORAGE AND UTILITY AREAS, ETC): Flammable liquids (such as gasoline, solvents, propane (LP) or butane, etc.) or other substances (such as adhesives, etc.), all of which emit flammable vapors, may be improperly stored or used in such areas. The gas water heater ignitor or main burner can ignite such vapors. The resulting flashback and fire can cause death or serious burns to anyone in the area, as well as property damage. If installation in such areas is your only option, then the installation must be accomplished in a way that the ignitor and main burner flame are elevated from the floor at least 18 inches. While this may reduce the chances of flammable vapors from a floor spill being ignited, gasoline and other flammable substances should never be stored or used in the same room or area containing a gas water heater or other open flame or spark producing appliance. Also, the water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle. NOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.

CAUTION

WATER HEATERS EVENTUALLY LEAK: Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow of water will not cause damage to the structure. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are available at your local hardware store. Such a drain pan must have a minimum length and width of at least 2 inches greater than the water heater dimensions and must be piped to an adequate drain. Drain pan depth must allow for access to the outer doors for servicing the ignitor and burner. Under no circumstances is the manufacturer to be held liable for any water damage in connection with this water heater.

WARNING

Do not use an extension cord. If there is not a suitable receptacle with ground and/or local codes prohibit use of a power cord, field wiring must be provided.

If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one.

WARNING

3412) equal BTU/Hr. rate. Your local jurisdictional authority, while mandating the use of a temperature-pressure relief valve complying with ANSI Z21.22 and ASME, may require a valve model different from the one furnished with the water heater. Compliance with such local requirements must be satisfied by the installer or end user of the water heater with a locally prescribed temperature-pressure relief valve installed in the designated opening in the water heater in place of the factory furnished valve. For safe operation of the water heater, the relief valve must not be removed from it’s designated opening or plugged. The temperature-pressure relief valve must be installed directly into the fitting of the water heater designated for the relief valve. Position the valve downward and provide tubing so that any discharge will exit only within 6 inches above, or at any distance below the structural floor. Be certain that no contact is made with any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet, or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve. No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6″″air gap is provided. To prevent bodily injury, hazard to life, or property damage, the relief valve must be allowed to discharge water in quantities should circumstances demand. If the discharge pipe is not connected to a drain or other suitable means, the water flow may cause property damage. The discharge pipe: —Must not be smaller in size than the outlet pipe size of

the valve, or have any reducing couplings or other restric-

tion. —Must not be plugged or blocked. —Must be of material listed for hot water distribution. —

Must be installed so as to allow complete drainage of both

the temperature-pressure relief valve, and the discharge pipe. —Must terminate at an adequate drain. —Must not have any valve between the relief valve and tank.

Installing the New Water Heater (cont’d)

Filling the Water Heater

To fill the water heater with water:

1. Close the water heater drain valve by turning the handle to the right (clockwise). The drain valve is on the lower front of the water heater.

2. Open the cold water supply valve to the water heater.

NOTE: The cold water supply valve must be left open when the water heater is in use.

3. To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping.

4. Check all new water piping for leaks. Repair as needed.

Wiring

The water heater comes equipped with a 7 foot power cord which can be used to connect to a 110/120 volt power source if, (1) local codes allow, and (2) there is a three prong receptacle available.

This unit must have a grounded

outlet to operate.

You must provide all wiring, (1) to a receptacle or, (2) between the water heater and junction box when the power cord is not used.

OPTIONAL Field Installed Wiring

1. Provide a way to easily shut off the electric power when working on the water heater. This could be with a circuit breaker or fuse block in the entrance box or a separate disconnect switch.

2. Install and connect a circuit directly from the main fuse or circuit breaker box. This circuit must be the right size and have its own fuse or circuit breaker.
