The location chosen for the water heater must take into consideration the following:Local Installation RegulationsElectrical Code. It is available from somelocal libraries or can be purchased fromthe National Fire Protection Association,Batterymarch park, Quincy, MA 02269as booklet ANSI/NFPA 70.LocationLocate the water heater in a clean dryarea as near as practical to the area ofgreatest heated water demand. Longuninsulated hot water lines can wasteenergy and water.Place the water heater in such a mannerthat the thermostat and elementaccess panels can be removed to permitinspection and servicing such as removalof elements or checking controls.The water heater and water lines shouldbe protected from freezingtemperatures. Do not install the waterheater in outdoor, unprotected areas.Care and CleaningBA—Diameter of waterheater plus 2″ min.B—Maximum 2″Operating InstructionsCAUTION: The water heater shouldnot be located in an area where leakageof the tank or connections will result indamage to the area adjacent to it or tolower floors of the structure. Wheresuch areas cannot be avoided, it isrecommended that a suitable catchpan, adequately drained, be installedunder the water heater.Installation InstructionsThis water heater must be installed inaccordance with these instructions, localcodes, utility codes, utility companyrequirements or, in the absence of localcodes, the latest edition of the NationalSafety InstructionsInstalling the water heater.ATroubleshooting TipsTo open drain, lineshould be at least 3/4″ID and pitched forproper drainage.NOTICE: Auxiliary catch pan MUST conform to local codes.Catch Pan Kits are available from the store where the waterheater was purchased, or any water heater distributor.Customer ServiceInspect ShipmentInspect the water heater for possible damage. Check the markings on the ratingplate of the water heater to be certain the power supply corresponds to the waterheater requirements.5
Thermal ExpansionDetermine if a check valve exists in the inlet water line. It may have been installedin the cold water line as a separate back flow preventer, or it may be part of a pressurereducing valve, water meter or water softener. A check valve located in the cold water inletline can cause what is referred to as a “closed water system”. A cold water inlet line withno check valve or back flow prevention device is referred to as an “open” water system.As water is heated, it expands in volume and creates an increase in the pressure withinthe water system. This action is referred to as “thermal expansion”. In an “open” watersystem, expanding water which exceeds the capacity of the water heater flows back intothe city main where the pressure is easily dissipated.A “closed water system”, however, prevents the expanding water from flowing back intothe main supply line, and the result of “thermal expansion” can create a rapid anddangerous pressure increase in the water heater and system piping. This rapid pressureincrease can quickly reach the safety setting of the relief valve, causing it to operate duringeach heating cycle. Thermal expansion, and the resulting rapid and repeated expansion andcontraction of components in the water heater and piping system can cause prematurefailure of the relief valve, and possibly the heater itself. Replacing the relief valve will notcorrect the problem!The suggested method of controlling thermal expansion is to install an expansion tank inthe cold water line between the water heater and the check valve (refer to the illustrationbelow). The expansion tank is designed with an air cushion built in that compresses as thesystem pressure increases, thereby relieving the over pressure condition and eliminating therepeated operation of the relief valve. Other methods of controlling thermal expansion arealso available. Contact your installing contractor, water supplier or plumbing inspector foradditional information regarding this subject.Water Supply ConnectionsNOTICE: Do not apply heatRefer to the illustration below for suggested typical installation. The installation ofto the HOT or COLD waterunions or flexible copper connectors is recommended on the hot and cold waterconnections. If sweatconnections so that the water heater may be easily disconnected for servicing ifconnections are used,necessary. The HOT and COLD water connections are clearly marked and are 3/4″ NPTsweat tubing to adapteron all models.

Safety InstructionsA new combination temperature and pressure relief valve, complying with the Standard for Relief Valvesand Automatic Gas Shut-Off Devices for Hot Water Supply Systems, ANSI Z21.22, is supplied and mustremain installed in the opening provided and marked for the purpose on the water heater. No valve of anytype should be installed between the relief valve and the tank. Local codes shall govern the installation ofrelief valves.Relief ValveThe BTUH rating of the relief valve mustnot be less than the input rating of thewater heater as indicated on the ratinglabel located on the front of the heater(1 watt 3.412 BTUH).To Fill the Water HeaterMake certain the drain valve is completelyclosed.Open the shut-off valve in the cold watersupply line.Open each hot water faucet slowly toallow the air to vent from the waterheater and piping.A steady flow of water from the hot waterfaucet(s) indicates a full water heater.Condensation can form on the tankwhen it is first filled with water.Condensation might also occur with aheavy water draw and very cold inletwater temperature.Troubleshooting TipsCondensationCare and CleaningWARNING: The tank must be full ofwater before heater is turned on. Thewater heater warranty does not coverdamage or failure resulting fromoperation with an empty or partiallyempty tank. (Refer to the Certificate ofLimited Warranty for complete termsand conditions.)Operating InstructionsConnect the outlet of the relief valveto a suitable open drain so that thedischarge water cannot contact liveelectrical parts or persons and toeliminate potential water damage.Piping used should be of a type approvedfor hot water distribution. The dischargeline must be no smaller than the outletof the valve and must pitch downwardfrom the valve to allow completedrainage (by gravity) of the relief valveand discharge line. The end of thedischarge line should not be threaded orconcealed and should be protected fromfreezing. No valve of any type, restrictionor reducer coupling should be installed inthe discharge line.Installation InstructionsWARNING: The pressurerating of the relief valvemust not exceed 150 PSI,the maximum workingpressure of the waterheater as marked onthe rating plate.Additional information on this subjectmay be found at www.rheem.comunder “Library”. Scroll down to theTechnical Service Bulletins 1300 SeriesSection and choose Bulletin #1303.Customer ServiceThis condition is not unusual, and willdisappear after the water becomesheated. If, however, the condensationcontinues, examine the piping andfittings for possible leaks.7
