INSTALLATION Follow these steps for properinstalla on:Water pressureincrease caused bythermal expansion Verify that yourhome is equippedand up-to-date forproper opera onInstalling a new water heater is theperfect me to examine your home’splumbing system and make sure thesystem is up to current code standards.There have likely been plumbing codechanges since the old water heater wasinstalled. We recommend installing thefollowing accessories and any otherneeded changes to bring your home upto the latest code requirements.Use the checklist below and inspectyour home. Install any devices you needto comply with codes and assure thatyour new water heater performs at itsbest. Check with your local plumbingofficial for more informa on. Water pressureWe recommend checking yourhome’s water pressure with a pressuregauge (Figure 4.) Most codes allow amaximum incoming water pressure of80 psi. We recommend a working pressure no higher than 50-60 psi.HOW: Purchase an inexpensive waterpressure gauge available at your localplumbing supplier. Connect the WaterPressure Gauge to an outside faucetand measure the maximum waterpressure experienced throughout theday (highest water pressures o en occur at night).Figure 4 - Use a Water Pressure Gauge tomake sure your home’s water pressure isnot too high.To limit your home’s water pressure:Locate your home’s Pressure Reducing Valve (PRV) on the main incoming(cold) water supply line and adjust thewater pressure control to between 50and 60 psi. If your home does not havea Pressure Reducing Valve, install aPRV on the home’s main water supplyline and set it to between 50 and 60psi. Pressure Reducing Valves are available at your local plumbing supplier.BACKGROUND: Over the years, manyu li es have increased water supply pressures so they can serve morehomes. In some homes today, pressures exceed 100 psi. High waterpressures can damage water heaters,causing premature leaks. If you havereplaced toilet valves, had a waterheater leak, or had to repair appliances connected to the plumbing system,pay par cular a en on to your home’swater pressure. When purchasing aPRV, make sure the PRV has a built-inbypass.Verify that you have a properly sizedThermal Expansion Tank (Figure 5). Werecommend installing an expansiontank if your home does not have one.Codes require a properly pressurized,properly sized Thermal Expansion Tankin almost all homes. (See photo oninside front cover.)Figure 5 - A Thermal Expansion Tank helpsprotect the home’s plumbing system frompressure spikes.HOW: Connect the Thermal ExpansionTank (available at your local plumbingsupplier) to the cold water supply linenear the water heater. The expansiontank contains a bladder and an aircharge. To work properly, the ThermalExpansion Tank must be sized according to the water heater’s tank capacityand pressurized to match the home’sincoming water pressure. Refer to theinstalla on instruc ons provided withthe Thermal Expansion Tank for installa on details.Residen al Electric Water Heater Use and Care Guide 7INSTALLATIONStep 1:

INSTALLATIONINSTALLATIONBACKGROUND: Water expands whenheated, and the increased volumeof water must have a place to go, orthermal expansion will cause largeincreases in water pressure (despitethe use of a Pressure Reducing Valveon the home’s main water supplyline). The Safe Drinking Water Act of1974 requires the use of backflowpreventers and check valves to restrictwater from your home reenteringthe public water system. Backflowpreventers are o en installed in watermeters and may not be readily visible.As a result, most all plumbing systemstoday are now “closed,” and almost allhomes now need a Thermal Expansion Tank.A Thermal Expansion Tank is a prac cal and inexpensive way to help avoiddamage to the water heater, washingmachine, dishwasher, ice maker andeven toilet valves. If your toilet occasionally runs for no apparent reason(usually briefly at night), that may bedue to thermal expansion increasingthe water pressure temporarily.Figure 6 - A suitable drain pan piped to anadequate drain can help protect flooringfrom leaks and drips. Install a suitable drain pan (available at your local plumbing supplier) under the water heater (Figure6) to catch condensation or leaksin the piping connections or tank.Most codes require, and we recommend, installing the water heaterin a drain pan that is piped to anadequate drain. The drain pan mustbe at least two inches wider thanthe diameter of the water heater.Install the drain pan so the waterlevel would be limited to a maximum depth of 1-3/4”. Water temperature regula onWater pipe and tankleaksLeaks from plumbing pipes or fromthe water heater itself can damageproperty and could cause a fire risk. Install an automatic leak detection and shutoff device (availableat your local plumbing supplier).These devices can detect waterleaks and can shut off the waterheater’s water supply if a leakoccurs.Figure 7 - Thermostatic Mixing Valvesinstalled at each point -of-use can helpprevent scalds.Install Thermosta c Mixing Valves(Figure 7) to regulate the temperatureof the water supplied to each pointof-use (for example, kitchen sink,8 Residen al Electric Water Heater Use and Care Guidebathroom sink, bath, shower). Consult the valve manufacturer’s instrucons or a qualified person.WARNING! Even if the water heaterthermostat is set to a rela vely lowtemperature, hot water can scald.Install Thermosta c Mixing Valves ateach point-of-use to reduce the risk ofscalding (page 4).BACKGROUND: A Thermosta c Mixing Valve, installed at each pointof-use, mixes hot water from thewater heater with cold water to moreprecisely regulate the temperature ofhot water supplied to fixtures. If youaren’t sure if your plumbing systemis equipped with properly installedand adjusted Thermosta c MixingValves at each point where hot wateris used, contact a qualified person formore informa on.

INSTALLATIONStep 6:Install shutoff andtempering valvesIf one is not already installed,install a manual shutoff valvein the cold water line thatsupplies the water heater. Install theshutoff valve near the water heater sothat it is readily accessible. Only usevalves that are compa ble withpotable water. Use only full-flow ballor gate valves. Other types of valvesmay cause excessive restric on to thewater flow.1Install a Thermosta c MixingValve at each point-of-use(for example, kitchen sink,bathroom sink, bath, shower).Consult the valve manufacturer’sinstruc ons or a qualified person.INSTALLATION2system (or any other pre-hea ngsystem), always install a Thermosta cMixing Valve or other temperaturelimi ng device in the inlet water supplyline to limit water supply inlettemperature to 120 F. Solar waterhea ng systems can supply water withtemperatures exceeding 170 F andmay result in water heatermalfunc on.WARNING! Hot water providedby solar hea ng systems can causesevere burns instantly, resul ng insevere injury or death (page 4).WARNING! Even if the waterheater’s thermostat(s) are set to arela vely low temperature, hot watercan scald. Install Thermosta c MixingValves at each point-of-use to reducethe risk of scalding. (page 4.)3For water heaters that are fedby a solar water hea ngIf your home has copper waterpipes, you can solder the waterpipe connec ons or use compression fi ngs which don’t requiresoldering. Compression fi ngsare easier to install than solderingpipe. Check with local plumbingofficials to determine what typesof pipe materials are suitable foryour loca on. Do not use leadbased solder.Step 7:1Connect the watersupplyDetermine the type of water pipes inyour home. Most homes use copperwater pipes, but some use CPVC orcross-linked polyethylene (PEX). Usefi ngs appropriate for the type of pipein your home. Do not use iron or PVCpipe – they are not suitable for potablewater.Connect the cold watersupply using 3/4 inchNa onal Pipe Thread “NPT”to the cold water inlet nipple.For ease of removing the water heaterfor service or replacement, connect the water pipes with a couplingcalled a union. We recommend usinga dielectric-type union (available atyour local plumbing supplier). Dielectric unions can help prevent corrosion caused by ny electric currentscommon in copper water pipes andcan help extend the life of the waterheater.2Figure 14 - Install Thermostatic MixingValves at each point where hot water willbe used.IF YOU HAVE COPPERPIPES:12 Residen al Electric Water Heater Use and Care GuideNOTICE: Do not solder pipes whilethey are a ached to the waterheater.
