Must not be in contact with any electrical part. . Must be connected to an adequate discharge line. . Must not be rated higher than the working pressure shown on the data plate of the water heater. . The BTUH rating of the T & P valve must be greater than, or equal to, the input rating of the water heater. The Discharge Line: . Must not be smaller than the pipe size of the relief valve or have any reducing coupling installed in the discharge line. . Must not be capped, blocked, plugged or contain any valve between the relief valve and the end of the discharge line. . Must terminate a maximum of 6 inches (152mm) above a floor drain or external to the building. . Must be capable of withstanding 250°F (121°C) without distortion. . Must be installed to allow complete drainage of both the valve and discharge line. Figure 9: T&P Relief Valve Explosion Hazard If the temperature and pressure relief valve is dripping or leaking, have a qualified service technician replace it. . Do not plug valve. . Do not remove valve. Failure to follow these instructions can result in death or explosion. Index Index 14 GAS SUPPLY AND PIPING Gas Requirements Read the data plate to be sure the water heater is made for the type of gas being used. This information will be found on the data plate located on the front of the water heater. If the information does not agree with the type of gas available, do not install or operate the water heater. Call your dealer. Note: An odorant may be added by the gas supplier to the gas used by this water heater. This odorant may fade over an extended period of time. Do not depend upon this odorant as an indication of leaking gas. Gas Piping The gas piping must be installed according to all local and state codes, or in absence of local and state codes, with the .National Fuel Gas Code., ANSI Z223.1 (NFPA 54)-latest edition. Canadian installations must be performed in accordance with CAN/CSA-B149.1. Note: If using a flexible gas connector, make sure its rating tag matches or exceeds the input of the water heater. Tables 2, 3A, and 3B on page 15 provide a sizing reference for commonly used gas pipe materials. Consult the .National Fuel Gas Code. or .Natural Gas and Propane Installation Code. for the recommended gas pipe size of other materials. Follow the instructions below and reference Figure 10 for gas piping installation. 1. Install a readily accessible manual shut-off valve in the gas supply line as recommended by the local utility. Know the location of this valve and how to turn off the gas to this unit. 2. Install a drip leg as shown. The drip leg must be no less than 3 inches (76mm) long for the accumulation of dirt,foreign material and water droplets. 3. Install a ground joint union between the water heater and the manual shut-off valve. This is to allow easy servicing. 4. Turn the gas supply on and check for leaks. Use a chloride-free soap and water solution (bubbles forming indicate a leak) or other approved method. Figure 10: Gas Piping Drip leg Check with local utility for min. height Ground Joint Union Manual Gas Shut-off Valve Gas Pressure Important: The gas supply pressure must not exceed the maximum supply pressure as stated on the water heater.s data plate. Minimum supply pressure should also be maintained per the data plate. Explosion Hazard Use a new AGA or CSA approved gas supply line. Install a shut-off valve. Do not connect a natural gas water heater to a L.P. gas supply. Do not connect a L.P. gas water heater to a natural gas supply. Failure to follow these instructions can result in death, explosion, or carbon monoxide poisoning. Index 15 15 Gas Pressure Testing Important: This water heater and its gas connection must be leak tested before placing the appliance in operation. . If the code requires the gas lines to be tested at a pressure of 14. W.C. or greater, the water heater and its manual shut-off valve must be disconnected from the gas supply piping system and the line capped. . If the gas lines are to be tested at a pressure less than 14. W.C., the water heater must be isolated from the gas supply piping system by closing its manual shut-off valve. U.L. recognized fuel gas and carbon monoxide(CO) detectors are recommended in all applications and should be installed using the manufacturer.s instructions and local codes, rules, or regulations. Note: Air may be present in the gas lines and could prevent the burner from lighting on initial start-up. The gas lines should be purged of air by a qualified service technician after installation of the gas piping system. Explosion Hazard Have a qualified service technician make sure L.P. gas pressure does not exceed 13. water column. Failure to do so can result in death, explosion, or fire. Index (Index) Index ELECTRICAL CONNECTIONS If you lack the necessary skills required to properly install the electrical wiring to this water heater, do not proceed but have a qualified service technician perform the installation.
