SAFETY PRECAUTIONS

Installing the water heater.The location chosen for the water heater must take into consideration the following:

Local Installation RegulationsThis 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 National

Electrical 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.

LocationThis water heater is designed to meet awide range of applications. It fulfills ademand for a small water heater that canbe installed in a limited space such as undercountertops, in cabinets or in a closet.

Locate the water heater in a clean dryarea as near as practical to hot waterfixtures, or close to the water faucetmost frequently used.

Locate 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 element

access panels can be removed to permitinspection and servicing such as removalof elements or checking controls.

The water heater and water lines should be protected from freezingtemperatures. Do not install the waterheater in outdoor, unprotected areas.

CAUTION: 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.

A—Diameter of waterheater plus 2″ min.

B—Maximum 2″

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.

Installing the water heater.

Thermal Expansion

Water Supply Connections

Determine if a check valve exists in theinlet water line. It may have been installed inthe cold water line as a separate back flowpreventer, 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“cclloosseedd wwaatteerr ssyysstteemm.” A cold water inletline with no check valve or back flow preventiondevice is referred to as an “open” watersystem.As water is heated, it expands in volume andcreates an increase in pressure within thewater system. This action is referred to as“tthheerrmmaall eexxppaannssiioonn.” In an “open” watersystem, expanding water which exceeds thecapacity of the water heater flows back intothe city main where the pressure is easilydissipated. A “cclloosseedd wwaatteerr ssyysstteemm,” however, preventsthe expanding water from flowing back intothe main supply line, and the result of“tthheerrmmaall eexxppaannssiioonn” can create a rapid anddangerous pressure increase in the water

heater and the system piping. This rapidpressure increase can quickly reach the safetysetting of the relief valve, causing it tooperate during each heating cycle. Thermalexpansion, and the resulting rapid andrepeated expansion and contraction ofcomponents in the water heater and pipingsystem can cause premature failure of therelief valve, and possibly the heater itself.Replacing the relief valve will not correct theproblem. The suggested method of controlling thermalexpansion is to install an expansion tank inthe cold water line between the water heaterand the check valve. The expansion tank isdesigned with an air cushion built in thatcompresses as the system pressureincreases, thereby relieving the over pressurecondition and eliminating the repeatedoperation of the relief valve. Other methods of controlling thermal expansion are alsoavailable. Contact your installing contractor,water supplier, or plumbing inspector foradditional information regarding this subject.

NOTICE: Do not apply heat to the HOT or COLDwater connections. If sweatconnections are used, sweattubing to adapter before fittingadapter to the waterconnections on heater. Anyheat applied to the watersupply fittings will permanentlydamage the dip tube and/orheat traps.

DANGER: Hotter waterincreases the Potential for Hot Water SCALDS.Households with smallchildren, disabled, orelderly persons may requirea 120°F or lower gas control(thermostat) setting toprevent contact with HOTwater.

!

Routine Preventative MaintenanceProperly maintained, your water heaterwill provide years of dependable trouble-free service.

It is suggested that a routine preventivemaintenance program be establishedand followed by the user.

It is further recommended that aperiodic inspection of the operatingcontrols, heating element and wiringshould be made by service personnelqualified in electric appliance repair.

Most electrical appliances, even whennew, make some sound when inoperation. If the hissing or singingsound level increases excessively, theelectric heating element may requirecleaning. Contact a qualified installer orplumbing contract to inspect.

At least once a year, lift and release thelever handle on the temperature pressurerelief valve, located near the top of thewater heater, to make certain the valveoperates freely. Allow several gallons toflush through the discharge line to anopen drain.

A water heater’s tank can act as asettling basin for solids suspended inthe water. It is therefore not uncommonfor hard water deposits to accumulate inthe bottom of the tank. It is suggestedthat a few quarts of water be drainedfrom the water heater’s tank every monthto clean the tank of these deposits.

Rapid closing of faucets or solenoidvalves in automatic water usingappliances can cause a banging noiseheard in a water pipe. Strategicallylocated risers in the water pipe systemor water hammer arresting devices canbe used to minimize the problem.

The anode rod should be removed from thewater heater’s tank annually for inspectionand replaced when more than 6″ of corewire is exposed at either end of the rod.

Make sure the cold water supply isturned off before removing anode rod.

NOTICE: Do not remove the anode rodfrom the water heater’s tank, except for inspection and/or replacement, as operation with the anode rodremoved will shorten the life of theglass lined tank and will excludewarranty coverage.

Care and cleaning of the water heater.

Draining the Water Heater

CAUTION: Shut off power to thewater heater before draining water.

DANGER: Before manually operatingthe relief valve, make certain no one willbe exposed to the hot water releasedby the valve. The water drained fromthe tank may be hot enough to presenta scald hazard and should be directedto a suitable drain to prevent injury ordamage.

In order to drain the water heater, turnoff the cold water supply. Open a hotwater faucet or lift the handle on therelief valve to admit air to the tank.

Attach a garden hose to the drain valveon the water heater and direct thestream of water to a drain. Open thevalve.

Vacation and Extended Shut-DownIf the water heater is to remain idle for anextended period of time, the power andwater to the appliance should be turnedoff to conserve energy and prevent abuild-up of dangerous hydrogen gas.

The water heater and piping should bedrained if they might be subjected tofreezing temperatures.

After a long shut-down period, the waterheater’s operation and controls shouldbe checked by qualified service personnel.Make certain the water heater iscompletely filled again before placing it in operation.

NOTICE: Refer to theHydrogen Gas Caution inthe Operating Instructions.

DANGER: Beforemanually operating therelief valve, make certainno one will be exposed tothe danger of coming incontact with the hot waterreleased by the valve. Thewater may be hot enoughto create a scald hazard.The water should bereleased into a suitabledrain to prevent injury orproperty damage.

NOTICE: If the temperatureand pressure relief valve on the hot water heaterdischarges periodically, this may be due to thermalexpansion in a closed water system. Contact the water supplier or your plumbing contractoron how to correct this. Do not plug the relief valve outlet.
