1. thermal expansion In an open water system expanding water which exceeds the capacity of the water heater flows back into the city main where the pressure is easily dissipated A closed water system however prevents the expanding water from flowing back into the main supply line and the result of thermal expansion can create a rapid and dangerous pressure increase in the water heater and system piping This rapid pressure increase can quickly reach the safety setting of the relief valve causing it to operate during each heating cycle Thermal expansion and the resulting rapid and repeated expansion and contraction of components in the water heater and piping system can cause premature failure of the relief valve and possibly the heater itself Replacing the relief valve will not correct the problem The suggested method of controlling thermal expansion is to install an expansion tank in the cold water line between the water heater and the check valve see illustration below The expansion tank is designed with an air cushion built in that compresses as the system pres sure increases thereby relieving the over pressure condition and eliminating the repeat ed operation of the relief valve Other methods of controlling thermal expansion are also available Contact your installing contractor water supplier or plumbing inspector for additional information regarding this subject Water Supply Connections Refer to the ill2. 3 Q 5 a a x c 2 e 3 7 sdij Bunooys jqnoIL BuluealD pue aep IM I WOJSNI Replacement Parts For 30 40 and 50 gallon models using natural or LP gas Instructions For Placing a Parts Order Safety Instructions To place orders using a Visa MasterCard Part description as noted below call 800 431 549 and number of parts desired All parts orders should include CAUTION For your safety DO x NOT attempt repair of gas piping The model and serial number ofthe thermostat burners vent connectors water heater from the rating plate or other safety devices Refer repairs S pecify type of gas natural or LP to qualified service personnel as marked on the rating plate Installation Instructions Draft hood Flue baffle ______ pe pressure relief valve hanger NN c Dip t SmartWater a For models equipped with gasket Striker Assembly Thermostat iD Mounting Bracket N c Q p Q gt p N f r g o a O An Pilot Tube 2 i ee ae Burner Assembly Includes Igniter and Cable ass y Care and Cleaning Drain valve shroud Drain valve pe Troubleshooting Tips Burner Pilot on burner aJ Se Thermocouple Wy DTD Pilot supply tube Inner door Customer Service Jacket door Burner orifice 22 Burner supply tube Please place in envelope and mail to Rheem Manufacturing Com
