Smith INSTALLATION CONSIDERATIONS 1. Condensate Drain -This is a fully condensing water heater and should be located near a drain to permit proper disposal of condensate. 2. Vent Termination - Exhaust gases of this water heater are less than 140 °F. In cold climates water vapor in flue gases will condense into a cloud of vapor where the vent exits the building. This vapor can gradually discolor exterior building surfaces. Vent termination should be located where this vapor cloud and potential discoloration are not a concern. Locating vent termination 6" or more from the wall helps vapor from being trapped along a building's face. To avoid this problem, the vent can be terminated on the roof. Always locate vent termination above the maximum snowline, and do not locate vent termination above a walkway. 3. Air Intake - In cold climates, air intake should be located at least three feet from the vent termination of the water heater and any other appliance vents that discharge moisture -laden air (such as clothes dryers). This will help prevent freeze -over of the intake screen required to prevent foreign objects from entering the intake pipe. Air intake should be located above the maximum snowline. 4. Blockage Sensors - The water heater is equipped with sensors to shut it down if blockage of vent or air intake occurs. A light on the heater's diagnostic panel will alert service technicians to this problem. 5. Noise - Vent terminal should be located away from bedroom windows or other areas where blower noise will be objectionable. Avoid venting into corners or confined areas, which will amplify sound. Anchoring intake or vent pipe to walls or ceilings can cause noise to be transmitted to living areas, and isolation mounts should be used where anchoring is required. 6. Optional Concentric Vent Kit - Helps to minimize unsightly wall /roof penetrations.

A I ET} IN AN AREA WHERE THE GENERAL PUBLIC; DOE=S NOT HAVE A∎-.CESS TO SETTEMPERAI ORES. The water temperature is controlled using the Temperature Control Button on the Display at the front of the unit (See Figure 1). This control utilizes two temperature probes to determine the tank temperature. The primary temperature probe is located at the top of the tank and the other is near the water inlet. The temperature may be adjusted from 90 °F /32 °C to 180FI82°C. The thermostat was adjusted to 120 °F /49 °C before the heater was shipped from the factory. It is recommended that lower water temperature be used to avoid the risk of scalding. It is further recommended, in all cases, that the water temperature be set for the lowest temperature which satisfies your hot water needs. This will also provide the most energy efficient operation of the water heater and minimize scale formation. SETTING THE WATER HEATER TEMPERATURE AT 12n "F /4P' WILL REDUCE THE RISK OF SCALDS. Some states require settings at specific lower temperatures. Figure 1 shows the approximate time -to -burn relationship for normal adult skin. Short repeated heating cycles caused by small hot water uses can cause temperatures at the point of use to exceed the thermostat setting by up to 20 °F/11 °C. If you experience this type of use, you should consider using lower temperature settings to reduce scald hazards. Temperature Setting 180 °F /82 °C 170 °F / 77 °C 160 °F /71 °C 150F/66°C 140 °F /60 °C 130 °F /54 °C 120 °F /49 °C Time to Produce 2nd & 3rd Degree Burns on Adult Skin Nearly instantaneous Nearly instantaneous About 1/2 second About 1 -1/2 seconds Less than 5 seconds About 30 seconds More than 5 minutes FIGURE 1. Valves for reducing point -of -use temperature by mixing cold and hot water are available (see Figure 2). Also available are inexpensive devices that attach to faucets to limit hot water temperatures. Contact a licensed plumber or the local plumbing authority. HOT WATER OUTLET TEMPERED WATER OUTLET COLD WATER INLET 12 "TO15" CHECK VALVE t MIXING VALVE CHECK VALVE TO TANK INLET FIGURE 2. HIGH LIMIT SWITCH (E.C.O.) The top immersion well of the dual bulb controller also contains the high limit (energy cutoff) sensor. The high limit switch interrupts the main burner gas flow should the water temperature reach approximately 202F/94°C Should the high limit switch activate, the control system will automatically reset the unit once the water temperature in the tank falls below 140 °F / 60 °C. If the unit is manually shut down and restarted, as long as the temperature in the tank Is lower than 160 "F /71 °C, the unit will reset and initiate operation. High limit switch operation is the likely cause when higher than normal water temperatures occur with a recurring need to restart the water heater. This could be due to a malfunctioning thermostat allowing the gas valve to remain open and the burner to continue firing even after water temperature in the tank has already reached the set point Contact your dealer or servicer if continued high limit switch operation occurs. 4 DISHWASHING MACHINE REQUIREMENT All dishwashing machines meeting the National Sanitation Foundation requirements are designed to operate with water flow pressures between 15 and 25 pounds per square inch (103 Kpa and 173 Kpa). Flow pressures above 25 pounds per square inch (173 Kpa), or below 15 pounds per square inch (103 Kpa), will result in improperly sanitized dishes. Where pressures are high, a water pressure reducing or flow regulating control valve should be used in the 180 °F (82 °C) line to the dishwashing machine, and should be adjusted to deliver water between these limits. The National Sanitation Foundation also recommends circulation of 180 °F (82 °C) water. Where this is done, the circulation should be very gentle so that it does not cause any unnecessary turbulence inside the water heater. The circulation should be just enough to provide 180 °F (82 °C) water at the point of take -off to the dishwashing machine. Adjust flow by means of the plug cock in the circulating line. (See installation diagrams.) CIRCULATING PUMP A circulating pump is used when a system requires a circulating loop or there is a storage tank used in conjunction with the heater. Refer to the piping diagrams at rear of manual for electrical hookup information and install in accordance with the current edition of the National Electrical Code, NFPA 70 or the Canadian Electrical Code, CSA C22.1. All bronze circulators are recommended for used with commercial water heaters. Although circulators are oiled and operated by the manufacturer some circulators must be oiled again before operated. Please refer to manufacturer's instructions. INSTALLATION INSTRUCTIONS REQUIRED ABILITY INSTALLATION OR SERVICE OF THIS WATER HEATER REQUIRESABILITY EQUIVALENT TO THAT OF A LICENSED TRADESMAN IN THE FIELD INVOLVED. PLUMBING, AIR SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK ARE REQUIRED. INSULATION BLANKETS Insulation blankets available to the general public for external use on gas water heaters are not approved for use on your A.O. Smith water heater. 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 ASHRAE /IES 90.1 1999 standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary.

When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance. Water heater life depends upon water quality, water pressure and the environment in which the water heater is installed. Water heaters are sometimes installed in locations where leakage may result in property damage, even with the use of a drain pan piped to a drain. However, unanticipated damage can be reduced or prevented by a leak detector or water shut -off device used in conjunction with a piped drain pan. These devices are available from some plumbing supply wholesalers and retailers, and detect and react to leakage in various ways: • Sensors mounted in the drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected. • Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan. • Water supply shut -off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater.

FIGURE 6b. 9 IMPORTANT The vent system must terminate so that proper clearances are maintained as cited in local codes or the current editions of the National Fuel Gas Code, ANSI Z223.1 /NFPA 54 or the Natural Gas and Propane Installation Code, CAN /CSA- 8149.1. Do not terminate the exhaust vent terminal over public area where condensate or vapor can cause nuisance or hazard. Plan the vent system layout so that proper clearances are maintained from plumbing and wiring. Vent pipes serving power vented appliances are classified by building codes as "vent connectors ". Required clearances from combustible materials must be provided in accordance with information in this manual under LOCATION OF HEATER and CLEARANCES, and with National Fuel Gas Code and local Codes. IMPORTANT Plan the layout of the vent system backwards from the vent termination to the appliance. ® WARNING USE ONLY THE VENT TERMINALS SUPPLIED WITH THIS UNIT. TERMINATION OF A VENT SYSTEM WITH A DEVICE OTHER THAN THE SUPPLIED VENT TERMINATIONS WILLAFFECTSYSTEM PERFORMANCE AND RESULT INA SAFETY HAZARD. DIRECT VENTING The air intake provided on the unit contains a mesh screen (see Figure 7) to prevent large particles from entering the unit. 3" (7.6cm) 45° PVC ELBOW WITH MESH SCREEN FIGURE 7. A WARNING WHEN THE UNIT IS TO BE SETUP ASADIRECT VENT, THE MESH SCREEN MUST BE REMOVED. THE INLET VENT PIPE MAY TI 1EN BE GLUED TO THE AIR INTAKE (see Figure 8) PROVIDED ON THE UNIT. DIRECT VENT TERMINAL INSTALLATION IMPORTANT THIS UNIT CONSISTS OF TWO VENT TERMINALS - AN INTAKE VENT TERMINAL AND AN EXHAUST VENT TERMINAL. THE INTAKE VENT TERMINAL ISA 3" 45° PVC ELBOW WITHADOME MESH WIRE SCREENAND THE EXHAUST VENT TERMINAL ISA 3" 45 °PVC ELBOW WITH A MESH WIRE SCREEN. NOTE: TO PREVENT EXHAUSTING PRODUCTS FROM CIRCULATING TO THE AIR INTAKE IN WINDY /COLD AREAS, THE MAXIMUM PRACTICAL DISTANCE BETWEEN THESE TWO TERMINALS IS RECOMMENDED. 10 FIGURE 8. IMPORTANT WHEN LOCATING THE TERMINALS ON A SIDEWALL, THE FOLLOWING SPECIFICATIONS PERTAINING TO TERMINAL LOCATION MUST BE FOLLOWED. 1. The intake vent terminal and the exhaust vent terminal must terminate on the same exterior wall and must be located at a minimum of 24" (61 cm) from the vertical centerline of the exhaust vent terminal (see Figure 9). In colder climates increasing the 24" (61cm) minimum will reduce possibility of frost over from side winds blowing exhaust vapors to the air intake of the direct vent. 2. The horizontal centerline of the intake vent terminal may not be located lower than the horizontal centerline of the exhaust vent terminal (see Figure 9). INSTALLATION SEQUENCE For installations in the City of Los Angeles, California Category IV PVC Pipe such as that manufactured by Brownline Pipe Company. must be used as vent pipe material CAUTION Vent terminals supplied with the heater must be used. NOTE: BEFORE BEGINNING INSTALLATION OF ANY VENT PIPE READTHE VENT PIPE MANUFACTURERS INSTALLATION INSTRUCTIONS. 1. After the points of termination have been determined, use the cover plates as templates to mark the holes for the vent pipes to be inserted through the wall. BEWARE OF CONCEALED WIRING AND PIPING INSIDE OF WALL. 2. If the vent terminals are being installed on the outside of a finished wall, it may be easier to mark both the inside and outside wall. Align the holes by drilling a hole through the center of the template from the inside through to the outside. The template can now be positioned on the outside wall using the drilled holes as a centering point for the template. 3. A) MASONRY SIDE WALLS Chisel an opening approximately 1/2" (1.3 cm) larger than the marked circle. B) WOODEN SIDE WALLS Drill a pilot hole approximately one quarter inch outside of the marked circle. This pilot hole is used as a starting point for a saws -all or sabre saw blade. Cut around the marked circle staying approximately one quarter inch outside of the line. (This will allow the vent pipe to easily slide through the opening. The resulting gap will be covered by the vent terminal cover plates.) Repeat this step on the inside wall if necessary. 4. Cut a length of 3" PVC pipe about 3.5" (8.9 cm) longer than the wall thickness at the opening. 5. Glue the intake vent terminal to the section of the pipe. 6. Slide the wall plate over the pipe to stop against intake vent terminal. 7. Place a bead of caulking (not supplied) around the gap between the pipe and the wall. Place some of the caulking on the back of the plate to hold it against the wall after installation. 8. If the vent pipe is installed up to the wall, with a coupling on the end against the wall opening, the pipe with the vent terminal can be prepared for gluing before inserting through the wall. Slide the pipe through the wall and insert into coupling on the other side of the wall, making sure that the vent terminal ends up pointed in the correct position (See Figure 9).

The intake vent termination and the exhaust vent termination must penetrate the same side of roof. 4. The center line of the intake vent termination and the center line of the exhaust vent termination must be no closer than 24" (61cm). 5. The intake vent terminal and the exhaust vent terminal must be oriented facing downward and the same direction. The specifications are displayed in Figure 10 & 11. NOTE: Exhaust vent terminal is installed using the same procedure. INSTALLATION SEQUENCE NOTE: BEFORE BEGINNING INSTALLATION OF ANY VENT PIPE, READ "VENT PIPE PREPARATION" SECTION ON PAGE 12. 1. After the points of termination have been determined, use the cover plates as templates to mark the holes for the vent pipes to be inserted through the roof. 2. Drill a pilot hole approximately 1/4" (6 mm) outside of the marked circle. This pilot hole is used as a starting point for a saws -all or sabre saw blade. Cut around the marked circle staying approximately one quarter inch outside the line. (This will allow the vent pipe to easily slide through the opening). The resulting gap will be covered by the roof boot/flashing. 3. Suspend the pipe through the center of the hole using proper support. 4. Slide roof boot or equivalent flashing over pipe and secure roof boot equivalent flashing to roof. 5. Seal around flashing. 6.

FURNACE, DRYERS OR SPACE HEATERS). IT IS CRUCIAL THAT THE VENTING ARRANGEMENT BE KEPT SEPARATE FROM OTHER VENTING SYSTEMS. IF THIS WARNING IS IGNORED, AND THE SYSTEM IS VENTED INCORRECTLY. IT MAY CAUSE IMPROPER OPERATION. FIRE. EXPLOSION. OR ASPHYXIATION. 1. Plan the route of the vent system from the vent termination to the planned location of the appliance. Layout the total vent system to use the minimum of vent pipe and elbows possible. 2. The installer may add up to a MAXIMUM OF FIFTY (50) EQUIVALENT FEET (15.2 m) of pipe to the exhaust venting arrangement. This addition of FIFTY (50) EQUIVALENT FEET (15.2 m) of pipe on both the intake venting arrangement and exhaust venting arrangement must include any 3" PVC elbows which equals (5) EQUIVALENT FEET (1.5 m) of pipe. Table 2. VENT LENGTH TABLE Number of 90° Elbows 3" Minimum Pipe (Ft. /M.) 3" Maximum Pipe (Ft. /M.) 4" Maximum Pipe (Ft. /M.)

The maximum number of 90° elbows with the 4" venting is six (6) on the intake and six (6) on the exhaust. A 90° elbow is equal to five (5) equivalent feet (1.5m) of pipe. One (1) 90° elbow is equal to two (2) 45° elbows. Any venting configuration using less than 50 equivalent feet should use 3" venting. See Table 2. The 3" venting terminals (provided) must be used with the 3" vent pipe. Two, approved 4" vent terminals (not provided) must be used with 4" vent pipe. See replacement parts list for terminals. IMPORTANT When multiple units are direct vented through a wall (3" or 4" venting), all intake vent terminals should be no lower than the highest exhaust vent terminal. NOTE: This unit can be vented using only PVC (Class 160, ASTM D -2241 Schedule 40, ASTM D -1785 ; or Cellular Core Schedule 40 DWV, ASTM F -891) , Schedule 40 CPVC (ASTM F -411), or ABS (ASTM D -2661) pipe. The fittings, other than the TERMINATIONS should be equivalent to PVC - DWV fittings meeting ASTM D -2665 (Use CPVC fittings, ASTM F -438 for CPVC pipe and ABS fittings, ASTM D- 2661/3311 for ABS pipe. If CPVC or ABS pipe and fittings are used, then the proper cement must be used for all joints, including joining the pipe to the Termination (PVC Material). PVC Materials should use ASTM D -2564 Grade Cement; CPVC Materials should use ASTM F -493 Grade Cement and ; ABS Materials should use ASTM D -2235 Grade Cement. NOTE: for Water Heaters in locations with high ambient temperatures (above 100 °F or 38 °C) and /or insufficient dilution air, it is recommended that CPVC or ABS pipe and fittings (MUST USE SUPPLIED VENT TERMINAL) be used. 4. It is important that condensate not be allowed to buildup in the exhaust vent pipe. To prevent this from happening the pipe should be installed with a slight, 118" (3mm) per 5 (152 cm) of pipe maximum downward slope. 5. The vent system should be supported every 5 (152 cm) of vertical run and every 3' (91cm) of horizontal run of vent pipe length. NOTE: Stress levels in the pipe and fittings can be significantly increased by improper installation. If rigid pipe clamps are used to hold the pipe in place, or if the pipe cannot move freely through a wall penetration, the pipe may be directly stressed, or high thermal stresses may be formed when the pipe heats up and expands. Install accordingly to minimize such stresses. 12 VENT PIPE PREPARATION 1. INITIAL PREPARATION A. Make sure the solvent cement you are planning to use is designed for the specific application you are attempting. B. Know the physical and chemical characteristics and limitations of the PVC, PVC cellular core, ABS or CPVC piping materials that you are about to use. C. Know the reputation of your pipe and cement manufacturer and their products. D. Know your own qualifications or those of your contractor. The solvent welding technique of joining PVC, PVC cellular core, ABS or CPVC pipe is a specialized skill just as any other pipe fitting technique. E Closely supervise the installation and inspect the finished job before start -up. F. Contact the manufacturer, supplier, or competent consulting agency if you have any questions about the application or installation of PVC, PVC cellular core, ABS or CPVC pipe. G. Take the time and effort to do a professional job. Shortcuts will only cause you problems and delays in start-up. The majority of failures in these systems are the result of shortcuts and /or improper joining techniques. 2. SELECTION OF MATERIALS PRIMER It is recommended that Tetrahydrofuran (THF) be used to prepare the surfaces of pipe and fittings for solvent welding. Do not use water. rags, gasoline or any other substitutes for cleaning PVC cellular core, ABS or CPVC surfaces. A chemical cleaner such as MEK may be used. CEMENT The cement should be a bodied cement of approximately 500 to 1600 centipoise viscosity containing 10 -20% (by weight) virgin PVC material solvated with tetrahydrofuran (THF). Small quantities of dimethyl formamide (DMF) may be included to act as a retarding agent to extend curing time. Select the proper cement; Schedule 40 cement should be used for Schedule 40 pipe. Never use all- purpose cements, commercial glues and adhesives or ABS cement to join PVC or CPVC pipe and fittings. SAFETY PRECAUTION PRIMERS AND CEMENTS ARE EXTREMELY FLAMMABLE AND MUST NOT BE STORED OR USED NEAR HEAL OR OPEN FLAME. ALSO. USE ONLY IN A WELL - VENTILATEDAREA. CONTROLS AND SWITCHES All BTH models are provided with four pressure switches. These switches are essential to the safe and proper operation of the unit. All switches are wired in series. The controller is set up to shut the unit down whenever there is a failure of any of the switches. It is important to understand the purpose of each switch. 1 INTAKE �'�' 11Pir./ � ; r � BLOCKED INLET PROVING SWITCH BLOWER PROVING AIR SWITCH LOW GAS PRESSURE SWITCH NOTE: LOW GAS IS LOCATED ON INLET SIDE OF GAS VALVE. BLOWER ASSEMBLY TO CONDENSATE ELBOW BLOCKED OUTLET PROVING SWITCH FIGURE 12. BLOWER PROVER SWITCH (SEE FIGURE 12) The Blower Prover Switch is provided on the heater to verify that the fan is operating. It is a positive pressure switch whose electrical contacts are normally open. When the fan increases the pressure in the burner, the pressure switch will allow the electrical contacts to close. The pressure switch is connected to the burner tap by a piece of tygon tubing This tubing must be connected in order for the switch to change the electrical contacts. The controller requires that the electrical contacts on this air flow switch be open before it will allow the blower to come on. BLOCKED OUTLET PROVER SWITCH (SEE FIGURE 12) The Blocked Outlet Prover Switch is set up to shut the unit off when a build- up of positive pressure in the exhaust vent pipe occurs. This switch is a positive pressure switch that requires an increase in pressure to change the electrical contacts from normally closed to open. When this switch prevents the unit from igniting, most likely the exhaust is blocked by some means Check to see if the condensate is allowed to flow freely from the exhaust elbow and for obstructions in the exhaust venting and exhaust vent terminal. Also verify that there is no more than fifty equivalent feet (15.2 m) of three inch PVC vent pipe on the exhaust. BLOCKED INLET PROVER SWITCH (SEE FIGURE 12) The Blocked Inlet Prover Switch is set up to shut the unit off when a build- up of negative pressure in the intake vent pipe occurs. This switch is a negative pressure switch that requires an increase in negative pressure to change the electrical contacts from normally closed to open. The switch is connected to the pressure tap on the PVC flange connected to the inlet of the blower. When this switch prevents the unit from igniting, most likely the intake is blocked by some means. Check to see if there is no more than fifty equivalent feet (15.2 m) of three inch PVC vent pipe on the intake. Also verify that the intake and intake vent terminal is free of obstructions that may prevent air from entering the unit. LOW GAS PRESSURE SWITCH (SEE FIGURE 12) The Low Gas Switch (LGS) is a single -pole, normally open pressure switch that will close its contacts when a rising pressure of 5.0 in. (1.25Kpa) W.C. is encountered. The contacts will open when the pressure falls below the fixed set point of 4.8 "WC (1.18Kpa) for natural gas models and 8.5 "WC (2.08Kpa) for propane models. The LGS monitors the gas supply pressure to the heater. If the gas supply falls below 4.8 "WC (1.18Kpa). the main burner is extinguished (if heater is running) or the heater will not start up. ON /OFF SWITCH The ON /OFF Switch is a single -pole, single -throw rocker switch, This switch provides 120V from the line source to the heater.

HOT SURFACE IGNITER The Hot Surface Igniter is a device that ignites the main burner by high temperature ( >1800 °F or >982 °C). When 120VAC is applied to the igniter, sufficient heat is generated to ignite the main burner. Although improvements have been made to strengthen the igniter, it is still fragile and care must be taken when handling the igniter to prevent breakage. GAS PIPING 13 Contact your local gas service company to ensure that adequate gas service is available and to review applicable installation codes for your area. Size the main gas line in accordance with Table 3. The figures shown are for straight lengths of pipe at 0.5" (125Pa) W.C. pressure drop, which is considered normal for low pressure systems Note that fittings such as elbows and tees will add to the pipe pressure drop.

Operating States In the main desktop screen, there are some specific Operating States that are indicated on the status line. These are summarized below: STATE DESCRIPTION Standby The water heater is not in an active heating cycle. Usually this means the temperature in the tank has reached a sufficient temperature and has not dropped low enough to initiate a call for heat. Input Verification The electronic controls are waiting for specific conditions to occur (primarily pressure switch states) before the unit can continue to heat water. Short Cycle Delay The electronic controls are waiting a defined period of time before initiating another call for heat just after the last on has ended. This prevents the water heater from "Short Cycling." Pre -Purge The blower has been energized and excess gas in the heater exchanger is being flushed to start a new heating cycle.

Fault and Warning Conditions This water heater is equipped with electronic controls that have the ability to monitor almost all aspects of the water heater operation. In the case that there is an undesirable or unsafe condition that occurs, the water heater controls will detect this condition and determine the appropriate action. Part of this is displaying the information on the LCD in plain text that accu- rately describes the condition and diagnostics information that can be used to correct the issue. There are two types of conditions that can occur during operation. These are Warnings and Faults: • Warnings: This is a non - safety related condition that the control has detected that may cause the water heater to operate in a less than optimal condition, but does not pose a safety concern. NOTE: When these conditions occur, continued heating cycles will con- tinue and the heater will attempt to regulate the water in the tank to the Operating Set Point.

ADJUSTMENT PROCEDURE INITIAL START -UP -120 AND 150 MODELS Main line gas pressure to the water heater for natural gas should be between a maximum of 10.5" (2.59Kpa for natural gas) W.0 (14.0 " /3.45Kpa for propane) and a minimum as shown in Table 4: that is, for Natural Gas, 4.8 (1.18Kpa) W.C. and 8.5" (2.08Kpa) for Propane Gas. The inlet gas pressure must not exceed the maximum value. A service regulator must be installed within 10' (305 cm) of the unit. 1. Check gas line pressure with a manometer. 2. Check manifold pressure (see Table 4, page 20) using a pressure gauge (manometer) connected to the manifold pressure tap on the gas control valve, (Figurel5). If full rate adjustment is required, remove cover screw from top of the gas control valve, (Figure 15). Using a small screwdriver, turn adjusting screw clockwise to increase or counterclockwise j1 to decrease gas pressure to obtain 4.0" (1 kPa) for natural gas and 10.0" W.C. (2.5 Kpa) for L.P. Gas. 3. Cycle the burner on and off several times to check its operation. 4. Check the operation of the limit and operating controls. 21 5. Check the vent system seams and joints and ensure that there is no discharge of flue products into the room. 6. Check the input rate. For appliance installation locations with elevations above 6500 feet (1982 meters) refer to HIGH ALTITUDE INSTALLATIONS section of this manual. a. Attach a pressure gauge (manometer) to the manifold pressure tap (Figure 16) and refer to Table 4. page 20 for correct pressure. b. Use this formula to "clock" the meter. Be sure other gas consuming appliances are not operating during this interval. 4Q X H = Btuh Should it be necessary to adjust the gas pressure to the burner, to obtain the full input rate, the steps below should be followed: T = Time in seconds to burn 1 cubic foot of gas. (With a stopwatch read the gas meter and measure the amount of time required for the heater to consume 1 cubic foot of gas.) H = Heating value of gas (in Btu's per cubic foot of gas). Btuh = Actual heater input rate, in Btuh. EXAMPLE: (Using BTH -150 heater) T = 25.25 seconds H = 1050 Btu /ft.3 BTUH = ? 3600 X 1050 = 150,000 Btuh (44 Kw) 25.25 For high altitude installations, compare result to the derated input required for the elevation at the installation location. c. Remove the pressure regulator cover screw (Figure 16) and adjust the pressure by turning the adjusting screw with a small screwdriver. Do not exceed 4.0" (1 kPa) natural gas models and 10.0" W.C. (2.5Kpa) on the propane models. d. e. f. f Clockwise to increase gas pressure and input rate. Counterclockwise to decrease gas pressure and input rate. "Clock" the meter as in step (b) above. Repeat steps (c) and (d) until the specified input rate is achieved. Turn the manual gas valve to "OFF ". Replace the pressure regulator cover screw. Remove the pressure gauge or manometer from the manifold pressure tap. Replace the set screw in the manifold pressure tap. If the gas pressure regulator cannot be adjusted to give the full input rating with sufficient gas pressure at the valve, check to ensure the unit is equipped with the correct orifice. ADJUSTMENT PROCEDURE INITIAL START -UP -199 AND 250 MODELS Main line gas pressure to the water heater for natural gas should be between a maximum of 10.5" (2.59Kpa for natural gas) W.C. (14.0 " /3.45Kpa for propane) and a minimum as shown in Table 4: that is, for Natural Gas 4" ( 98Kpa) WC and 9 0" (1 97Kpa) for Propane Gas. The inlet gas pressure must not exceed the maximum value. A service regulator must be installed within 10' (305 cm) of the unit. The BTH 199 and 250 models incorporate a new gas control, which operates at 0 "W.C. (OkPa) for both natural and propane gas. These models are configured prior to being shipped from the factory and no adjustments are necessary prior to startup. The controller monitors the air -flow and makes adjustments to the fan speed which in effect controls the amount of gas flow. Therefore, the unit will self- adjust to acquire the correct amount of input. Once the unit is installed and filled with water and the inlet pressures confirmed, simply turn the switch "on" and observe operation. Cycle the unit "off" and "on" several times to ensure proper operation. A WARNING UNDER NO CIRCUMSTANCES SHOULD THE INPUT EXCEED THE RATE SHOWN ON THE HEATER RATING PLATE. OVER FIRING COULD RESULT IN DAMAGE OR SOOTING OF THE HEATER. CATHODIC PROTECTION CAUTION HYDROGEN GAS CAN BE PRODUCED INA HOT WATER SYSTEM SERVED BY THIS HEATER THAT HAS NOT BEEN USED FOP A LONG PERIOD Or- TIME (GENERALLY TWO WEEKS OR MORE). HYDROGEN GAS IS EXTREMELY FLAMMABLE. To reduce the risk of injury under these conditions, it is recommended that a hot water faucet be opened for several minutes 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.

Open the drain valve and allow water to flow until it runs clean. 3. Close the drain valve when finished flushing. 4. Turn on the heater electrical disconnect switch. DRAINING The heater must be drained if it is to be shut down and exposed to freezing temperatures. Maintenance and service procedures may also require draining the heater. 1. Turn off the heater electrical disconnect switch. 2. Close the cold water inlet valve to heater. 3. Open a nearby hot water faucet to vent the system. 4. Open the heater drain valve. 5. If the heater is being drained for an extended shutdown, it is suggested the drain valve be left open during this period. • Follow FILLING instructions when restoring hot water service. SEDIMENT REMOVAL Waterborne impurities consist of the particles of soil and sand which settle out and form a layer of sediment on the bottom of the tank. For convenience, sediment removal and lime scale removal should be performed at the same time. LIME SCALE REMOVAL The amount of calcium carbonate (lime) released from water is in direct proportion to water temperature and usage. The higher the water temperature or water usage, the more lime deposits are dropped out of the water. This is the lime scale which forms in pipes, heaters and on cooking utensils. Lime accumulation not only reduces the life of the equipment but also reduces efficiency of the heater and increases fuel consumption. The usage of water softening equipment greatly reduces the hardness of the water. However, this equipment does not always remove all of the hardness (lime). For this reason it is recommended that a regular schedule for deliming be maintained. The depth of lime buildup should be measured periodically. Heaters will have about 3" (7.6cm) of lime buildup when the level of lime has reached the bottom of the cleanout opening or about 1" (2.5cm) of lime buildup if it has reached the drain valve opening. A schedule for deliming should be set up, based on the amount of time it would take for a 1" (2.5cm) buildup of lime. Example 1: Initial inspection shows 1/2" (1.3cm) of lime accumulation. Therefore, the heater can be delimed once a year. Example 2 : Initial inspection shows 2" (5cm) of lime accumulation. Therefore, the heater should be delimed every 3 months. Sediment and lime scale removal may be accomplished through the cleanout opening furnished on the heater, see Figure 25. The heater must be drained, see DRAINING, before removing cleanout cover on tank. 26 TANK CLEANOUT OPENING CLEANOUT GASKET CLEANOUT ACCESS PANEL CLEANOUT COVER FIGURE 16. To dissolve and remove the more stubborn mineral deposits, A.O. Smith UN•LIME® Professional Delimer should be used. A.O. Smith UN•LIME® Professional Delimer is an easy to handle patented food grade acid formulated specifically for lime scale removal from all types of water using equipment. Available in 1 gallon (3.8L) (part no. 4763) and 5 gallon (19L) (part no. 4813) sizes. Hydrochloric base acids' are not recommended for use on glass -lined tanks. A.O. Smith Form No. 4800, entitled "Why, When and How", describes tank cleaning methods and materials. UN•LIME and the booklet may be obtained through your A.O. Smith dealer or distributor. The cleanout opening is shown in Figure 16. To clean heater through cleanout opening, proceed as follow: 1. Turn off water inlet valve, the heater electrical disconnect switch and open drain valve. 2. Remove outer cover plate from lower side of heater jacket. 3. Remove cover from cleanout opening. 4. Remove lime, scale or sediment using care not to damage the glass - lining. 5. Inspect cleanout plate gasket: If new gasket is required, replace with A. 0. Smith part no. 99038. 6. Install cleanout plate. Be sure to draw plate up tight by tightening screws securely. 7. Close drain valve, open water inlet line and turn on the power burner electrical disconnect switch. 8. Check for water leakage. 9. Replace outer jacket cover plate. POWERED ANODE SYSTEM The BTH 120 -250 are factory equipped with a powered anode system. The anodes are of a permanent design and do not need replacing unless damaged. DRAIN VALVE AND ACCESS PANELS The heaters are equipped with a 3/4" drain valve. An access panel covers the cleanout opening in the tank which is sealed by a gasket and cover, figure 25. RELIEF VALVE At least twice a year, the temperature and pressure relief valve should be checked to ensure that it is in operating condition. To check the relief valve, lift the lever at the end of the valve several times. The valve should seat properly and operate freely. If water does not flow, remove and inspect for obstructions or corrosion. Replace with a new valve of the recommended size as necessary. Inspection of the valve should be performed at least every three years. Do not attempt to repair the valve, as this could result in improper operation and a tank explosion. In areas with poor water conditions, it may be necessary to inspect the T&P valve more often than every three years. A CAUTION BEFORE MANUALLY OPERATING THE VALVE, MAKE SURE THATA DRAIN LINE HAS BEENATTACHED TO THE VALVE TO DIRECTTHE DISCHARGETO AN OPEN DRAIN. FAILURE TO TAKE THIS PPFCAUTION COUI.D MEAN CONTACT WI 1H EXIREMEIYHO1 WAIERPASSINC,i,_li iHI- VAI.vE DURING THIS CHECKING OPERATION. If the temperature and pressure relief valve on the heater discharges periodically or continuously, it may be due to thermal expansion of water in a closed water supply system. or, it may be due to a faulty relief valve. Thermal expansion is the normal response of water when it is heated. In a closed system, thermal expansion will cause the system pressure to build until the relief valve actuation pressure is equaled. Then, the relief valve will open, allowing some water to escape. slightly lowering the pressure. Contact your water supplier or local plumbing inspector on how to control this situation. Two common corrections are listed in the Checklist and Service Information which appears later in this manual. ABOVEALL, DO NOT PLUG THE TEMPERATUREAND PRESSURE RELIEF VALVE. THIS IS NOT A SOLUTION AND CAN CREATE A HAZARDOUS SITUATION. CIRCULATING PUMP The water heating system may include a circulating pump. Where used, it should be lubricated as directed by the circulator manufacturer. VENT SYSTEM Examine the vent system every 3 months. Points of inspection are as follows: 1. Check for obstructions and/or deterioration of vent piping and vent hood. Replace Immediately where needed. 2. Vent pipe and vent hood screen should be cleaned of foreign material and soot. The screen is located inside the vent hood outlet and is accessible from the outside of the hood. Do not reach inside the vent hood when the heater is in operation. 3. Check all vent system connections for leakage and reseal as required using Hi Temp Silicone sealer or equivalent. 27 INSTALLATION DIAGRAMS ONE TEMPERATURE - ONE HEATER VERTICAL STORAGE TANK FORCED CIRCULATION WITH OR WITHOUT BUILDING RECIRCULATION INSTALL THERMAL EXPANSION TANK IF CHECK VALVE OR PRESSURE REDUCING VALVE IS USED IN A COLD WATER SYSTEM CAUTION: IF THE PLUMBING REQUIRES THE USE OF PIPES WITH DISSIMILAR MATERIAL_ (FOR EXAMPLE, STEEL AND COPPER), USE DIELECTRIC UNIONS TO PREVENTAN ELECTRO- GALVANIC ACTION BETWEEN THE PIPING COMPONENTS WITH DISSIMILAR MATERIALS.

HOWEVER, it is recommended that only qualified servicemen, using appropriate test equipment, be allowed to service the heater. BE SURE TO TURN OFF THE ELECTRICITY WHENEVER POSSIBLE OR APPROPRIATE WHILECHECKING EQUIPMENT. ® WARNING FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN SERIOUS PERSONAL INJURY OR DEATH. CAUTION: t ABELALLWIRES PRIOR TO DISCONNECTION WHEN SERVICING CONTROLS. WIRING ERRORS CAN CAUSE IMPROPERAND DANGEROUS OPERATION. VERIFY PROPER OPERATIONAF1 ER SERVICING BURNER OPERATIONAL PROBLEMS 1. Refer to TROUBLESHOOTING. NOT ENOUGH OR NO HOT WATER 1. Be certain the electrical disconnect switch serving the water heater is in the ON position. 2. Check the fuses. • The electrical disconnect switch usually contains fuses. 3. The capacity of the heater may have been exceeded by a large demand for hot water. Large demands require a recovery period to restore water temperature. 4. Colder incoming water temperature will lengthen the time required to heat water to the desired temperature. • If the heater was installed when incoming water temperature was warm, colder water creates the effect of less hot water. 5. Look for hot water wastage and leaking or open hot water faucets. 6. Sediment or lime scale may be affecting water heater operation. Refer to MAINTENANCE for details. 7. Bumer may not be firing at proper rate. • Check gas pressure. Adjust to obtain required manifold pressure. 8. Burner fan wheel may be dirty. • Clean fan wheel with a stiff brush. 9. Condensate hose may be blocked where it connects to the exhaust elbow. • Verify the condensate drains from the unit without restriction. WATER IS TOO HOT 1. Refer to WATER TEMPERATURE CONTROL. WATER HEATER MAKES SOUNDS 1. Sediment or lime scale accumulations cause rumbling and pounding noises when the heater is operating. The sounds are normal, however, the tank bottom should be cleaned. Refer to MAINTENANCE for details. 34 2. Some of the electrical components of the water heater make sounds which are normal. • Contacts click or snap as the heater starts and stops. • Transformers often hum. WATER LEAKAGE IS SUSPECTED 1. Check to see if the water heater drain valve is tightly closed. Also check the cleanout opening for leakage. 2. The apparent leakage may be condensation which forms on cool surfaces of the heater and piping. 3. If the outlet of the relief valve is leaking it may represent: Excessive water pressure. Excessive water temperature. • Faulty relief valve. Excessive water pressure is the most common cause of relief valve leakage. It is often caused by a "closed system ". If a check valve is in the inlet system it will not permit the expanded hot water volume to equalize pressure with the main. The relief valve must release this water or the water heater or plumbing system will be damaged. Refer to MAINTENANCE - RELIEF VALVE section in this manual. When such a condition is encountered. local codes or inspection agency should be consulted to determine which system is acceptable in your area. See CLOSED SYSTEM section in this manual also. TROUBLE - SHOOTING 1. Verify that the allowable vent length has not been exceeded and that the blower inlet screen has been removed if direct venting. 2. Verify that the condensation, which WILL be present in the heater and exhaust vent, will drain. 3. Check supply wire polarity - hot to hot and neutral to neutral and no "stray" current in neutral. 4. Heater is properly grounded. Checking these four (4) items first will often result in a timely solution to the service call.

WILL Before performing any troubleshooting familiarize yourself with the particular appliance. Refer to the SEQUENCE OF OPERATION and the connection diagram located on page 15 before continuing. Make sure the appliance is connected to a 120V AC power supply, manual gas valve is in the ON position, and all electrical connections are secure before continuing to troubleshoot this appliance. A CAUTION THE WATER HEATER IS POLARITY SENSITIVE. BEFORE APPLYING ELECTRICITY TO THIS HEATER BE CERTAIN THAT SUPPLY HEATED WIRE TO GROUND CHECK INDICATES ZERO VOLTAGE. MOTOR WILL NOT RUN 1. Confirm 120V AC to the controller. Also. to verify correct polarity, check for 120 V AC between hot supply and ground. If there is no voltage, check for a loose connection where it connects to the controller. 2. If there is 120 volts to the controller, check for loose connections or a locked rotor. If the rotor cannot be freed the motor and blower assembly must be replaced. MOTOR RUNS, PREPURGE TIME ELAPSES BUT MAIN FLAME NOT ESTABLISHED. 1. Check to see if main manual gas valve is open. 2. Check for a loose connection at the transformer, or a defective transformer. 3. Check for a loose connection at the gas valve. 4. Check for open pressure switches or open reset button. Check for blockage in the intake and exhaust venting or at the vent hoods. If no blockage is found, check vinyl tubing for cuts or crimps. If this tubing is damaged it must be replaced. If these steps do not eliminate the problem, replace the pressure switches. 5. Check to see if there is resistance across the igniter terminal with an OHM meter. If there is no continuity, the igniter is broken and should be replaced. If the igniter appears to function properly, then verify that the inlet pressure is within the range shown in Table 4. The gas valve supplied on the appliance is not designed to open against a higher inlet pressure of 10.5 "WC (2.59kPa) for natural gas and 14.0 "WC (3.45kPa) for propane gas. At this time, also check to make sure the inlet pressure is not lower than 4.0 "WC (.98kPa) for natural gas and 11.0 "WC (2.74kPa) for propane gas. If the inlet pressure is not within these limits then adjust the supply pressure accordingly. If the inlet pressure falls within the allowable limits, then verify that the manifold pressure, when the gas is fully open, with the heater running, is as called out in Table 4: that is, 4.0 "WC (.98kPa) for natural gas and 10.0 "WC (2.46kPa) for propane gas for the 120 and 150 models and 0 "WC (OkPa) for both natural and propane gas 199 and 250 models. If the manifold pressure is not correct then adjust accordingly. See "ADJUSTMENT PROCEDURE" in "OPERATING INSTRUCTIONS" sections for manifold pressure adjustment procedure. 6. If the inlet and manifold pressures are within the limits specified in step 5, then reset the appliance. Verify 24V AC at the gas valve during the three (3) second ignition trial, after the igniter reaches operating temperature. If 24V AC at the gas valve is not seen during this period, the controller must be replaced. If there is 24V AC at the gas valve during the four second ignition trial and the manifold pressure does not increase above 0" W.C. then verify that the manual gas control valve is in the "ON" position (see page 20). If the valve is in the "ON" position and the previous voltage and gas pressure conditions are met. then the gas valve is defective and must be replaced. Note that a positive manifold pressure reading of approximately 1.5" (.38 kPa) W.C. is normal during the prepurge portion of the ignition cycle due to the location of the gas orifice. MOTOR RUNS, BURNER LIGHTS MOMENTARILY, THEN LOCKS OUT 1. Reset the appliance two more times to ensure that all of the air has been purged from the gas line. 2. If the burner lights momentarily but does not sustain ignition, verify that the inlet pressure is not greater than 10.5 -WC (2.59 kPa) for natural gas and 14.0 "WC (3.45 kPa) for propane gas or lower than the minimal supply pressure which is 4.0 "WC (.09kPa) for natural gas and 11.0 "WC (2.74 kPa) for propane gas. Also, verify that the manifold pressure is correct, that is, 4.0 "WC (.98kPa) for natural gas and 10.0 "WC (2.46kPa) for propane gas for the 120 and 150 models and 0 "WC (OkPa) for both natural and propane gas 199 and 250 models. If the manifold pressure is not correct then adjust accordingly. See "ADJUSTMENT PROCEDURE" in "OPERATING INSTRUCTIONS" sections for manifold pressure adjustment procedure. 3. Check for the reversed polarity in the supply wiring. This controller is polarity sensitive. If the hot and neutral supply wires are reversed, the controller will not sense flame. Reverse the supply wires and try to fire the unit. NOTE: Always turn off and disconnect main supply wiring before servicing the unit. 4. Check connecting wire to the flame sensor. Verify that the flame sensor has not been damaged in any way. 5. Verify that the air supply is adequate. The air inlet screen or blower wheel may be restricted. Also, check the installation for proper ventilation See AIR REQUIREMENTS. 6. Check the venting system for the correct sizing, excess or insufficient. See VENTING. 7. Check for maximum inlet pressure of 10.5 "WC (2.59 kPa) for natural gas and 14.0 "WC (3.45 kPa) for propane gas and the manifold pressure which is 4.0 "WC (.98 kPa) for natural gas and 10.0 "WC (2.46 kPa) for propane gas for the 120 and 150 models and 0 "WC (o kPa) for both natural and propane gas 199 and 250 models. Please note that the manifold pressure listed is the maximum value for the manifold pressure. Do not set the manifold pressure higher than the value show in Table 4. OVER FIRING the heater will result in a rough ignition and /or noisy operation. 35 8. Confirm that the air inlet screen (see Figures 7 & 8) is free of obstructions. A CAUTION Do not reach into the burner housing or combustion chamber if the heater is still hot. Allow the heater to cool and always use gloves as the combustion chamber and the burner sleeve and housing can become very hot after operation. OVER FIRING is a dangerous condition that must be corrected immediately. GAS FAILS TO SHUT OFF Check for defective gas valve or thermostat. If operation is incorrect, replace.
