****** Page 8 ****** (0 z z 8 Temperature Control Water temperature can be adjusted by turning the knob of the gas control/thermostat on the front of the water heater. Always read and understand safety instructions contained in the Use & Care Manual before adjusting the temperature setpoint. NOTE: Refer to Water Temperature in Safety Information, page 5. Safety and energy conservation should be considered when selecting the temperature setpoint of the water heater: • The recommended setpoint for the water heater is 1200F (490C), as water temperatures above 1250F can cause severe burns or death from scalding. • Lower temperature setpoints increase energy savings. • Higher temperature setpoints can increase the cleaning performance of dishwashers and washing machines, as well as killing bacteria. Mixing Valves If the water heater’s temperature is set above HOT (1200F/490C), supplemental mixing valves are recommended to reduce point-of-use water temperature by mixing hot and cold water in branch water lines. Contact a licensed plumber or local plumbing authority for additional information. Vacation Setting This setting is recommended when you will be away from the home for an extended period of time and hot water is not needed. The vacation setting will reduce the water temperature to 500F (100C) to conserve energy. NOTE: Refer to Hydrogen Gas Caution, page 4. 49-6000245 Rev. O

****** Page 9 ****** About the Gas Control/Thermostat – 1550F 1500F 1400F 1300F 1200F SOOF – 500F WITH HOTTER WATER ow PILOT TO LIGHT PILOT: PRESS HOLD KNOB IN PILOT POSITION PRESS IGNITER BUTTON UNTIL PILOT LIGHTS RELEASE KNOB WHEN STATUS LIGHT BLINKS COM STATUS WHITE All temperatures listed on the water heater’s gas control/thermostat are approximate. Maximum water temperatures occur just after the water heater has completed a heating cycle. To determine the water temperature at point-of-use, open a hot water faucet and hold a thermometer under the stream of water. Frequent, short uses of hot water can cause a phenomenon called stacking, when the temperature of the water at the top of the tank (closest to pipes delivering water to the home) exceeds the temperature at the bottom of the tank (where the gas control/ thermostat is located). Before use, always test the water temperature with your hand, keeping in mind that hotter water increases the danger of scalding. NOTE: Refer to Water Temperature in Safety Information, page 5. 49-6000245 Rev. O The gas control/thermostat is equipped with two safety shut-off devices: • One is designed to shut off gas to the water heater’s burner if the pilot light goes out. • The other is designed to shut off gas to the burner if the water heater exceeds normal temperatures. If one of these safety shut-off devices is activated, refer to Troubleshooting Tips, page 20. AWARNING If the water heater overheats or the gas supply fails to shut off, close the manual gas shut-off valve. Turn off gas to the water heater if it has been subjected to overheating, fire, flood or physical damage. (Refer to Lighting and Shutdown, page 7.) Do not operate the water heater again until it has been thoroughly checked by a qualified service technician. Do not use or attempt to repair the water heater if any part has been under water. Immediately call a qualified service technician to replace the unit. m z o z 9

Preventive Maintenance For years of dependable service, the following annual maintenance program is recommended: 1. Test the Temperature and Pressure Relief Valve. 2. Drain and Flush the Water Heater Tank. 3. Inspect the Anode Rod. 4. Inspect the Gas Control/Thermostat. 5. Inspect the Pilot Light and Burner. 6. Inspect Water and Gas Systems. NOTE: It is recommended that you call a service technician to perform these tasks. Temperature and Pressure Relief Valve ADANGER Risk of Scald – Before manually operating the relief valve, make certain no one will be exposed to the danger of coming in contact with 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. NOTE: 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 a qualified service technician to correct this. Do not plug the relief valve outlet. At least once a year, lift and release the lever handle on the temperature and pressure (T&P) relief valve, located on the right side of the water heater. Flush several gallons to the open drain below, confirming that the water flows freely through the T&P valve and discharge line. 49-6000245 Rev. O

****** Page 11 ****** Water Tank Draining and Flushing the Water Heater Over time, minerals contained in the water supply will begin to accumulate in the water heater’s tank. Drain and flush the water heater at least once a year to clean any mineral deposits from the tank and ensure they do not interfere with proper functioning of the water heater. If the water supply is particularly hard (high in mineral content), it may be necessary to perform this process more often. Draining the Tank: 1. Turn off the water heater and turn off gas to the unit. (See To Turn Off Gas To Appliance, page 7.) 2. Attach a garden hose to the drain valve located at the bottom of the unit and direct to a suitable drain. 3. Turn off the cold water supply. 4. Admit air to the tank by opening a hot water faucet or lifting the handle on the relief valve. 5. Open the drain valve. 49-6000245 Rev. O Flushing the Tank: 1. Follow the steps above to drain the water heater. 2. Once the water heater is empty, with the drain valve open and garden hose attached to the drain valve, turn on the cold water supply. 3. Allow several gallons to flush through the drain valve and hose to an open drain. 4. Turn off the water supply and allow any water remaining in the tank to drain. 5. Repeat steps 3 and 4 until water runs clear. 6. Close the drain valve and completely fill the tank before turning on gas and relighting the unit. The tank is full when water runs continuously from an open hot water faucet. Flushing should be done with an empty tank to promote additional removal of sediment.

****** Page 12 ****** Anode Rod Maintenance and Service z 12 Anode rods are designed and installed to protect and extend the life of residential water storage tanks. The anode rod must be removed from the water heater’s tank and inspected annually, and replaced when more than 6″ (15.2 cm) of core wire is exposed at either end of the rod. *NOTE: Artificially softened water will cause the anode rod to consume more rapidly. The gas and cold water supply must be turned off before servicing the 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 shorten the life of the glass-lined tank and will void warranty coverage. Some areas have water conditions that may cause an odor to develop in the water heater. Special alloy replacement rods are available to address this condition. *NOTE: Failure to replace the anode rod when consumed voids the warranty for the tank. Warranty coverage for all other components remains intact and is unaffected by this maintenance requirement. The replacement anode rod and the inspection for consumption are not covered by the warranty. Inspecting the Anode Rod: 1. Turn off the water heater and drain 1-2 gallons of water from the tank. (Refer to Draining the Tank, page 10.) 2. Remove the anode cap and foam insulation beneath it with a flathead screwdriver. (Refer to illustration below.) Remove anode cap and foam insulation in hole to expose anode fitting 3. Unscrew the anode rod using a 1 1/16″ socket/wrench and lift it out of the water heater. 4. Inspect the anode rod. If more than 6″ of core wire is exposed, the anode rod should be replaced. (Refer to illustration below.) If the anode rod has not been depleted, reinsert it into the water heater following steps 2-6 below. ACAUTION DO NOT touch the vent hood or vent pipe located in front of the anode rod. These are very hot and present a burn hazard. Replace anode rod if more than 6″ of core wire exposed Installing the Anode Rod: 1. If a new anode rod is required, be sure to purchase the same type. For further information, contact a qualified service technician or GEA Customer Support at GEAppliances.com/waterheater. 2. Apply pipe joint compound or pipe thread sealant tape to the threads of the anode rod. 3. Insert the anode rod into the water heater and tighten with a torque wrench to 50 +/- 5 ft-lbs. of torque. 4. Close the drain valve, turn on the water supply and open a hot water faucet to remove any air trapped in the water lines. 5. Check for any leaks and repair. 6. Ensure that the water heater is completely full before relighting it. (Refer to Lighting Instructions, page 7.) 49-6000245 Rev. O

****** Page 14 ****** (0 z z 14 Installation Instructions LOCAL INSTALLATION REGULATIONS This appliance must be installed in accordance with local codes or, in the absence of local codes, the National Fuel Gas code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA B149.1. Not for Installation in a Manufactured Home (Mobile Home). LOCATION The water heater should be installed indoors, in a dry, level area where the tank and water lines are protected from freezing temperatures. If needed, shims can be used under the base of the unit to level it. All water heaters are subject to leaking, due to the corrosive properties of water over time. A ground floor or basement installation is suggested, to avoid property damage should leakage occur. Inspect and maintain the water heater according to this manual to minimize the potential for leakage and, if required, install a catch pan piped to a suitable drain. Catch Pan Installation (If Required) Relief Valve Pipe Catch Pan Drain Catch Pan NOTE: The auxiliary catch pan MUST conform to local codes. Catch Pan Kits are available from the store where the water heater was purchased or GEApplianceparts.com. The catch pan outer diameter (OD) should be 3″ (7.62 cm) minimum larger than the Water Heater base diameter. LOCATION (Cont.) The installation must allow sufficient airflow for combustion and ventilation, and should be as close to a gas vent or chimney as possible. Avoid areas where the water heater could be exposed to flammable liquids and vapors or a corrosive atmosphere. The water heater can be installed on combustible flooring, but not directly on carpet. If the water heater must be located in a carpeted area, install a wood or metal panel as a barrier between the water heater and carpet; the panel should be 5″ larger than the water heater in all directions. To minimize thermal loss, the water heater should be close to the areas of greatest demand. Insulated water lines also help to maintain optimal temperatures from water heater to faucet. The installation must allow sufficient access to the top, front and sides of the water heater for service. Moving the water heater for service is not covered under the warranty. For installation requiring earthquake straps, minimal clearance around the sides of the water heater is acceptable. In this case, additional clearance should be provided on the opposite side of the unit to allow for service access. Refer to For Installations in the State of California, page 4.

****** Page 15 ****** Installation Instructions AIR SUPPLY AND VENTILATION Proper air supply and ventilation are essential to the safe, effective operation of this residential gas water heater. Air supply and ventilation must be in accordance with local codes or, in the absence of local codes, the National Fuel Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA B149.1. Air Supply If the water heater is installed in an open room of a conventionally constructed building, sufficient air is typically present for proper combustion and ventilation. However, if the water heater is installed in a confined space or tightly insulated home, additional provisions must be made for combustion and ventilation air. A confined space offers less than 50 cubic feet of air per 1 ,000 BTUH (British thermal units per hour) for the appliances in that space. Each appliance’s BTUH requirements should be listed on its rating plate. Without an adequate supply of clean air, the water heater’s pilot light will not function properly, and excessive amounts of carbon monoxide may be produced. Corrosive Atmospheres A corrosive atmosphere is created when compounds from aerosol sprays, cleaning products such as bleach and detergents or other chemicals become airborne and are drawn into the combustion air supply of a water heater or other gas appliance. When these compounds pass through the gas flame, they create corrosive elements that shorten the life of the appliance. Damage due to a corrosive atmosphere is not covered under the warranty. 49-6000245 Rev. O AIR SUPPLY AND VENTILATION (Cont.) Ventilation The ventilation system for this water heater must be properly installed by a qualified service technician and free from any obstructions. The vent should not be shared by any power-vented appliance, nor should a damper be used anywhere in the system. The new vent hood (provided with the water heater) must be attached to the gas vent or chimney by vent pipes. The diameter of the vent pipes must match that of the vent hood or be larger. At least 12″ of vertical vent pipe is recommended from the vent hood. Horizontal pipes must maintain a vertical pitch of at least 1/4″ per foot, and the termination must be vertical. Vent joints must be secured by an approved method, such as sheet metal screws. After the water heater’s main burner has been in operation for 5 minutes, the vent hood can be tested for spillage by holding a lighted match or candle close to the vent hood relief opening. The smoke or flame should be pulled towards the opening. For additional information, consult local codes, the National Fuel Gas code, ANSI Z223.1/NFPA 54 or the Natural Gas and Propane Installation Code, CSA 8149.1. THERMAL EXPANSION If the home’s inlet water line includes a check valve, this will prevent water from flowing back into the city’s water supply, creating a closed water system in the home. Heated water expands, causing increased pressure, which is then trapped in a closed water system. Referred to as thermal expansion, this rapid pressure increase can cause the water heater’s relief valve to operate (releasing water) during heating cycles, potentially causing premature failure of the valve or the water heater. To control thermal expansion, install a thermal expansion tank in the cold water line between the water heater and check valve, as shown in the next illustration, page 16. Contact your installing contractor, water supplier or plumbing inspector for additional information. z z o z 15

****** Page 16 ****** (0 z z z z Installation Instructions WATER SUPPLY AND DRAINAGE Refer to the illustration below for recommended installation. The HOT and COLD water connections are 3/4″ NPT (National Pipe Thread) and are clearly marked on all models. Use 3/4″ female NPT fittings with sealant suitable for potable water when connecting to the inlet/outlet ports. The installation of unions is recommended on the HOT and COLD water connections so that the water heater may be easily disconnected for service. Piping should be routed to allow for anode rod inspection and service. NOTE: Install a shut-off valve in the cold water line near the water heater. This will allow for easier service and maintenance of the unit. IMPORTANT: Do not apply heat to the HOT or COLD water connections. If sweat connections are used, sweat tubing to adapter before fitting the adapter to the COLD water connections on the water heater. Any heat applied to the HOT or COLD water connections will permanently damage the internal plastic lining in these ports.

****** Page 17 ****** Installation Instructions TEMPERATURE AND PRESSURE RELIEF VALVE AWARNING Risk of Unit Damage – The pressure rating of the relief valve must not exceed 150 PSI (1.03 MPa), the maximum working pressure of the water heater as marked on the rating plate. A new combination temperature and pressure (T&P) relief valve, complying with the Standard for Relief Valves and Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22/CSA 4.4, is supplied and must remain installed in the opening provided and marked for this 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. The BTUH rating of the temperature and pressure relief valve must not be less than the input rating of the water heater as indicated on the rating plate located on the front of the heater (1 watt=3.412 BTUH). Connect the outlet of the relief valve to a suitable open drain so that the discharge water cannot contact live electrical parts or persons and to eliminate potential water damage. 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. Relief Valve Insulation (Model appearance may vary) 49-6000245 Rev. O ACAUTION To reduce the risk of excessive pressures and temperatures in this water heater, install temperature and pressure protective equipment required by local codes and no less than a combination temperature and 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 Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22 /CSA 4.4. This valve must be marked with a maximum set pressure not to exceed the marked maximum working pressure of the water heater. Install the valve into an opening provided and marked for this purpose in the water heater, and orient it or provide tubing so that any discharge from the valve exits only within 6 inches above, or at any distance below, the structural floor, and does not contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstance. TO FILL THE WATER HEATER AWARNING – Risk of Unit Damage – The tank must be full of water before the water heater is turned on. The water heater warranty does not cover damage or failure resulting from operation with an empty or partially empty tank. 1 . Check that the drain valve is completely closed. 2. Open the shut-off valve in the cold water supply line. 3. Open hot water faucets slowly, allowing air to vent from the water heater and pipes. 4. Wait until there is a steady flow of water from the hot water faucets; this indicates that the water heater is full. 5. Check connections and pipes for any leakage. When the water heater is first filled with water, condensation may form on the tank and fittings. During use, condensation can be caused by a heavy water draw and very cold inlet water temperature. This condition is not unusual and will resolve after the water is heated. If condensation persists, examine fittings for potential leaks and repair as required. z z z o z 17

****** Page 18 ****** (0 z O 18 Installation Instructions GAS SUPPLY AWARNING Only connect this water heater to the type of gas listed on its rating plate. Any attempt to adapt the water heater for use with a different type of gas could cause hazardous operating conditions. The gas supply line should be composed of an approved gas piping material such as steel and properly sized for the water heater. Install an ANSI certified gas appliance connector or ground joint union in the gas line close to the water heater. Any flexible connectors in the gas line must be 36″ or shorter. Joint compound should be used sparingly on male threads only and must be resistant to liquid petroleum (LP) gas. The National Fuel Gas Code (NFGC) requires that a manual gas shut-off valve be installed. A sediment trap must be installed downstream of the shut-off valve, as close to the appliance as possible. Refer to the illustration below. Gas Supply Line (vertical install) Gas Supply Line (horizontal install) 3″ minimum Sediment Trap o Connect the pipe to the gas control/thermostat inlet using a maximum torque of 40 ft-lbs. torque. Gas pressure to the gas control/thermostat inlet must not exceed 14″ w.c. for natural gas or LP gas. The rating plate lists both the maximum and minimum inlet gas pressures for the water heater. If gas pressure is not within the acceptable range, contact your gas provider. Pressure Testing • Gas test pressures exceeding 14″ w.c. (1/2 PSI or 3.5 kPa) require disconnecting the water heater and gas shut-off valve from the gas supply line. • Gas test pressures of 14″ w.c. (1/2 PSI or 3.5 kPa) or lower require isolating the water heater from the gas supply line by closing the gas shut-off valve. GAS SUPPLY (Cont.) High Altitude AWARNING Do not install the water heater above the altitude specified on its rating plate. Installation above the certified altitude may cause the water heater to produce excessive amounts of carbon monoxide, which could cause serious injury or death. The water heater is certified for operation at high altitudes. Please see the rating plate on the water heater for maximum altitude. INSULATION BLANKETS This water heater is designed for energy efficiency. An insulation blanket is NOT RECOMMENDED, unless required by local codes. Any damage caused by an insulation blanket or other unapproved device is not covered under the warranty. Use of such devices can shorten the life of the water heater and pose a hazard to persons or property. If an insulation blanket is required by local codes: • DO NOT cover or attempt to relocate warning labels on the water heater. • DO NOT insulate the top of the water heater; this will interfere with proper functioning of the vent hood. • DO NOT cover the gas control/thermostat, gas valve, burner access door or temperature and pressure relief valve. • DO NOT insulate the bottom of the water heater or cover the combustion air inlets. • FREQUENTLY INSPECT the insulation blanket to ensure that it is securely in position and is not restricting airflow to the combustion air inlets at the base of the water heater. 49-6000245 Rev.

****** Page 19 ****** Installation Instructions COMBINATION POTABLE WATER AND SPACE HEATING This water heater is suitable for combination potable water and space heating applications; it is not suitable for space heating alone. If installed for combination water and space heating, components in both systems must be suitable for potable water. DO NOT connect the water heater to components that have been previously used for space heating alone, as they may be contaminated with toxic chemicals. Never introduce boiler treatment or other toxic chemicals into pipes or components connected with the water heater, as this will affect the potable water supply. If the space heating system requires water at a temperature higher than 1200F (490C), a mixing valve (meeting the Standard for Temperature Actuated Mixing Valves for Hot Water Distribution Systems, ASSE 1017) must be installed in the potable hot water line to reduce the danger of scalding. Installation must comply with local and national codes. NOTE: A maximum distance of 50′ €- 0″ from the water heater to fan coil (developed length) is required in Massachusetts State. 49-6000245 Rev.
