GENERAL SAFETY

INFORMATION

EXTERNAL DAMAGE

Do not operate the water heater until it has been fully checked out by a qualified technician, if the water heater:

Has been exposed to fire or damage.

Displays evidence of sooting.

Produces steam or unusually hot water.

If the water heater has been flooded it must be replaced.

CHEMICAL VAPOR CORROSION

WARNING

CORROSION OF THE FLUEWAYS AND VENT SYSTEM MAY OCCUR IF AIR FOR COMBUSTION CONTAINS CERTAIN CHEMICAL VAPORS. SUCH CORROSION MAY RESULT IN FAILURE AND RISK OF ASPHYXIATION.

Spray can propellants, cleaning solvents, refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride (water softener salt), waxes and process chemicals are typical compounds which are potentially corrosive.

Do not store products of this sort near the heater. Also, air which is brought in contact with the heater should not contain any of these chemicals. If necessary, uncontaminated air should be obtained from remote or outside sources. The limited warranty is voided when failure of water heater is due to a corrosive atmosphere. (Refer to the limited warranty for complete terms and conditions).

EXTENDED NON-USEPERIODS

WARNING

HYDROGEN GAS CAN BE PRODUCED IN A HOT WATER SYSTEM SERVED BY THIS HEATER THAT HAS NOT BEEN USED FOR A LONG PERIOD OF TIME (GENERALLY TWO WEEKS OR MORE). HYDROGEN GAS IS EXTREMELY FLAMMABLE.To reduce the risk of injury under these conditions, 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 probably be an unusual sound such as air escaping through the pipe as the water begins to flow. THERE SHOULD BE NO SMOKING OR OPEN FLAME NEAR THE FAUCET AT THE TIME IT IS OPEN.

INSULATION BLANKETS

Insulation blankets available to the general public for external use on gas water heaters are not necessary with A. O. Smith products. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank water heaters. Your A. O. Smith 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.

WARNING

Should you choose to apply an insulation blanket to this heater, you should follow these instructions (See Figure 1 for identification of components mentioned below). Failure to follow

these instructions can restrict the air flow required for proper combustion, resulting in fire, asphyxiation, serious personal injury or death.

Do not cover the outer door, thermostat or temperature & pressure relief valve.

Do not cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.

Do obtain new warning and instruction labels from A.O. Smith for placement on the blanket directly over the existing labels.

INSTALLATION

REQUIRED ABILITY

INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR SUPPLY, VENTING AND GAS SUPPLY ARE REQUIRED.

GENERAL

The installation must conform to these instructions and the local code authority having jurisdiction. In the absence of local codes, the installation must comply with the current editions of the National Fuel Gas Code, ANSI Z223.1/NFPA 54. The code is available from the Canadian Standards Association, 8501 East Pleasant Valley Road, Cleveland, OH 44131.

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 manufactured (mobile) homes or outdoor installation.

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

When installing the heater, consideration must be given to proper location. The water heater should be located as close to or centralized to the water piping system as possible. The water heater should be located in an area not subject to freezing temperatures.

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 HEATER OR TO LOWER FLOORS OF THE STRUCTURE. When such locations cannot be avoided, a suitable drain pan should be installed under

3

the heater. Such pans should have a minimum length and width of at least 2 inches greater than the diameter of the heater and should be piped to an adequate drain. Drain pans suitable for these heaters are available from your dealer or A. O. Smith Water Products Company, 5621 W. 115th Street, Alsip, IL 60803. Contact us at our website: www.hotwater.com, phone: 800.433.2545, or fax: 1.800.433.2515.

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

WARNING

DO NOT INSTALL THIS WATER HEATER DIRECTLY ON A CARPETED FLOOR. A FIRE HAZARD MAY RESULT. Instead the water heater must be placed on a metal or wood panel extending beyond the full width and depth by at least 3 inches (76.2mm) in any direction. If the heater is installed in a carpeted alcove or closet, the entire floor shall be covered by the panel.

Refer to figure 1 for typical installation. A suitable pipe thread sealant must be used to prevent leakage.

WATER (POTABLE) HEATING AND SPACE HEATING

1.All piping components connected to this unit for space heating applications shall be suitable for use with potable water.

2.Toxic chemicals, such as those used for boiler treatment, shall NEVER be introduced into this system.

3.This unit may NEVER be connected to any existing heating system or component(s) previously used with a non-potablewater heating appliance.

4.When the system requires water for space heating at temperatures higher than required for domestic water purposes, a tempering valve must be installed. Please refer to Fig. 2 for suggested piping arrangement.

CLOSED WATER SYSTEM

FIGURE 2

A closed system will exist if a back-flowpreventer (check valve), pressure reducing valve, or other similar device is installed in the cold water line between the water heater and the street main (or well). Excessive pressure may develop due to the thermal expansion of heated water causing premature tank failure or intermittent relief valve operation.This type of failure is not covered by the limited warranty. An expansion tank may be necessary in the cold water supply to alleviate this situation, see fig. 1. Contact the local plumbing authority.

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. Contact the water supplier or local plumbing inspector on how to correct this situation. DO NOT PLUG THE TEMPERATURE AND PRESSURE RELIEF VALVE.

GAS CONNECTIONS

The minimum gas supply pressure for input adjustment is 5.0” W.C. (1.2 kPa) for natural gas and 11.0” W.C. for propane gas. THE HEATER IS NOT INTENDED FOR OPERATION AT HIGHER THAN 10.5” WATER COLUMN (2.6 kPa) SUPPLY PRESSURE. EXPOSURE TO HIGHER GAS SUPPLY PRESSURE MAY CAUSE DAMAGE TO THE CONTROL WHICH COULD RESULT IN FIRE OR EXPLOSION. Ifover-pressurehas occurred such as through improper testing of gas lines or emergency malfunction of the supply system, the control must be checked for safe operation.

Make sure that the outside vents on the supply regulators and the safety vent valves are protected against blockage. These are parts of the gas supply system not the heater. Vent blockage may occur during ice storms.

IT IS IMPORTANT TO GUARD AGAINST CONTROL FOULING FROM CONTAMINANTS IN THE GAS WAYS. SUCH FOULING MAY CAUSE IMPROPER OPERATION, FIRE OR EXPLOSION.

All piping must comply with local codes and ordinances or with the current edition of National Fuel Gas Code (ANSI Z223.1/NFPA54) whichever applies.

REFER TO FIG. 1 FOR CONNECTION DETAILS. BEFORE ATTACHING THE GAS LINE BE SURE THAT ALL GAS PIPE IS CLEAN ON THE INSIDE.

TO TRAP ANY DIRT OR FOREIGN MATERIAL IN THE GAS SUPPLY LINE, A DIRT LEG (SOMETIMES CALLED DRIP LEG) MUST BE INCORPORATED IN THE PIPING, FIG. 1. The dirt leg must be readily accessible. Install in accordance with recommendations of serving gas supplier. Refer to the latest edition of the National Fuel Gas Code ANSI Z223.1.

To prevent damage, care must be taken not to apply too much

4

torque when attaching gas supply pipe to thermostat gas inlet. The thermostat inlet has a pad for use with a backup wrench.

Apply joint compounds (pipe dope) sparingly and only to the male threads of pipe joints. Do not apply compound to the first two threads. Use compounds resistant to the action of liquefied petroleum gases. Do not use teflon tape on thermostat fittings.

DISCONNECT THE APPLIANCE FROM THE GAS SUPPLY PIPING SYSTEM DURING ANY SUPPLY PRESSURE TESTING EXCEEDING 1/2 PSI (3.5 kPa). GAS SUPPLY LINE MUST BE CAPPED WHEN DISCONNECTED FROM THE HEATER. FOR TEST PRESSURES AT 1/2 PSI (3.5 kPa) OR LESS, THE APPLIANCE NEED NOT BE DISCONNECTED, BUT MUST BE ISOLATED FROM THE SUPPLY PRESSURE TEST BY CLOSING THE MAIN MANUAL GAS VALVE.

BEFORE PLACING THE HEATER IN OPERATION, CHECK FOR GAS LEAKAGE. USE SOAP AND WATER SOLUTION OR OTHER MATERIAL ACCEPTABLE FOR THIS PURPOSE. DO NOT USE MATCHES, CANDLES, FLAME OR OTHER SOURCES OF IGNITION TO LOCATE GAS LEAKS.

RELIEF VALVE

A NEW 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 (CURRENT EDITION) MUST BE INSTALLED IN THE HEATER IN THE MARKED OPENING PROVIDED (SEE FIGURE 1). THE VALVE MUST BE OF A SIZE (INPUT RATING) THAT WILL BE ADEQUATE FOR YOUR SIZE HEATER.

Check the metal tag on the relief valve and compare it to the heater’s rating plate. The pressure rating of the relief valve must not exceed the working pressure shown on the rating plate of the heater. In addition, the hourly BTU rated temperature steam discharge capacity of the relief valve shall not be less than the input rating of the heater. NO VALVE IS TO BE PLACED BETWEEN THE RELIEF VALVE AND TANK. DO NOT PLUG THE RELIEF VALVE.

The drain line connected to this valve must not contain a reducing coupling or other restriction and must terminate near a suitable drain to prevent water damage during valve operation. The discharge line shall be installed in a manner to allow complete drainage of both the valve and line. DO NOT THREAD, PLUG OR CAP THE END OF THE DRAIN LINE.

VENTING

WARNING

NEVER OPERATE THE HEATER UNLESS IT IS VENTED TO THE OUTDOORS AND HAS ADEQUATE AIR SUPPLY TO AVOID RISKS OF IMPROPER OPERATION, FIRE, EXPLOSION OR ASPHYXIATION.

DO NOT OBSTRUCT THE FLOW OF COMBUSTION AND VENTILATING AIR. ADEQUATE AIR FOR COMBUSTION AND VENTILATION MUST BE PROVIDED FOR SAFE OPERATION.

VENT PIPE TERMINATION

Before installing water heater determine placement of vent pipe termination.

MAKE CERTAIN TO OBSERVE VENT LOCATION LIMITATION, SEE FIG'S 4 & 5.

CAUTION

Use only the vent kit assembly supplied with this water heater or if needed one of the three listed optional flue extensions. See Figure 10 for possible combinations. VENTING OR TERMINATION WITH ANY OTHER KIT NOT LISTED IS NOT RECOMMENDED AND COULD AFFECT THE SYSTEMS PERFORMANCE AND RESULT IN A SAFETY HAZARD.

WARNING

MINIMUM CLEARANCES BETWEEN THE WATER HEATER AND COMBUSTIBLE AND NONCOMBUSTIBLE CONSTRUCTION ARE: 0 INCHES FROM SIDES, 0 INCHES FROM BACK, 4 INCHES FROM FRONT OF JACKET TO CLOSET DOOR AND 3 INCHES FROM TOP OF JACKET TO COMBUSTIBLE AND NONCOMBUSTIBLE MATERIAL. MINIMUM VENT CLEARANCE: 0 INCHES. PROVIDE 24 INCHES FRONT CLEARANCE FOR SERVICING AND ADEQUATE CLEARANCE BETWEEN THE JACKET TOP & CEILING FOR SERVICING THE FLUE AREA. (SEE FIGURE 3).

FIGURE 4

WARNING

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

OPTIONAL WIRE GRILL

When the water heater vent cap is low enough to be touched accidentally, or is accessible to small children, installation of a protective vent cover is recommended. Some local codes may require a vent cap cover. Figure 9 shows the optional wire vent cap protector available from the water heater manufacturer.

A wire mesh chain link fence (as shown in Figure 9) may be used instead of the factory cover. Care should be taken to maintain adequate ventilation around the vent cap. If a chain link fence is installed, it must not be used as a storage area for items that may block proper ventilation.

Unless otherwise specified at the time of ordering, a standard extension kit is individually packaged and shipped within the

water heater carton.

POSSIBLE EXTENSION COMBINATIONS

FIGURE 10

WARNING

At no time can more than one Vertical and/or one Horizontal Vent Kit be used.

VERTICAL (EXTENSION KIT) HEIGHT

It is simple to determine which kit is needed for vertical height. Take the total height (to the top of the flue) required and comparing that to “F DIMENSION” in TABLE 1, it can be determined which kit needs to be used vertically.

WARNING

Obstructions and deteriorated vent systems may present serious health risk or asphyxiation.

CUTTING THE OPENING THROUGH

THE OUTSIDE WALL

After thoroughly reading the “Locating the New Water Heater” section of this manual and you have chosen a suitable water heater installation site, use the chart below to determine dimensions for the opening in the wall.

Cut a 61/4” diameter hole completely through the outside wall.

WATER HEATER ATTITUDE

There is a certain amount of variance with regard to the direction the water heater faces.

Standing in front of the water heater (gas control facing you), set the 3” diameter elbow (slotted end) on the flue. This will give you a better understanding of the relation of the vent assembly to the opening in the wall and more importantly any possibly of interference of venting and water piping.

The direction of the water heater can now be made. Also consider the gas control valve to insure installation, lighting, and maintenance accessibility are retained.

STANDARD VENT KIT

INSTALLATION #1

*

The opening through the wall should be cut at this time. If it hasn’t been, refer back to that section.

1.Lock the elbow to the straight 3” flue pipe. Set this assembly in place on the end of the water heater’s flue collar.

FIGURE 15

2. Mark the flue collar at the slots in the elbow. Using a #22 drill bit, drill holes into the flue collar at the two slots and secure the elbow to the flue collar using the screws provided.

NOTE: Make sure elbow is properly aligned to opening in the outside wall.

FIGURE 16

3.Using the tube of sealant supplied, run an ample amount around the oval flare of the jacket.

FIGURE 13

FIGURE 17

4.First remove the 3” horizontal extension from the elbow. Starting with the long end (with four securing holes), place the 6” diameter vent elbow over the 3” diameter elbow.

Bend the round end “oval” to fit the flared oval end of the jacket top.

8.Slide the vent collar (to be installed later) over the 6” vent elbow.

FIGURE 18

5.Making sure the 6” diameter elbow is centered around the 3” diameter flue, secure the 6” diameter vent pipe using four sheet metal screws at the connection of the jacket top.

FIGURE 19

6. The standard vent kit includes a 6” diameter extension pipe which is used over 6 1/2”.

FIGURE 20

7.If “E” is less than 6 1/2” move to next step.

If “E” dimension is over 6 1/2”, assemble the 6” diameter extension pipe (crimped end) to the 6” diameter vent elbow and secure using two sheet metal screws.

FIGURE 21

FIGURE 22

9.Place the water heater at the opening in the wall, at the predetermined clearance.

FIGURE 23

10.Move outdoors with all the remaining vent parts. Using the tube of sealant supplied, run an ample amount on the inside surface of the collar assembly that will contact the exterior wall and also fill the bead on the end of the 6” diameter vent collar.

FIGURE 24

11.Install the vent collar assembly through the wall, connecting it to the extension and/or elbow (depending on which one was used).

FIGURE 25

FIGURE 27

13.Insert the 3” diameter flue extension pipe into the vent collar assembly (flared & notched end first) and lock (turn clockwise to lock studs to slots) the flue extension pipe to the flue elbow.

FIGURE 28

14.Connect the vent cap by sliding its end over the 3” diameter extension pipe and O-ring.

NOTE: To facilitate ease of assembly of the vent cap to the 3” pipe, a soap solution can be applied to the O-ringgasket.

FIGURE 29

15.The vent cap has 4 holes around the outer edge. Remove the 4 screws used to temporarily attach the collar to the exterior wall. Then secure the vent cap assembly with the vent collar assembly to the exterior wall using the same 4 screws.

NOTE: Screws are supplied; however, substitution may be necessary depending on the exterior wall material.

CAUTION

To prevent unlocking the previously installed 3” diameter extension, the vent cap assembly must be rotated in a clockwise motion when the vent cap is installed.

16.Go back indoors to attach inside collar to the inside wall. Place the collar against the wall. Secure to wall by using 4 long sheet metal screws.

FIGURE 30

NOTE: Screws are supplied; however, substitution may be necessary depending on the interior wall material.

17.Using the tube of sealant supplied, run an ample amount of sealant around the edge of the vent pipe where it is inserted through the inside collar to seal air drafts from wall.
