Introduction
The location chosen for the water heater must take into consideration thefollowing:! CAUTION
The water heater should not be located in an area where leakage ofthe tank or connections will result in damage to the area adjacent
to it or to lower floors of the structure. Where such areas cannot be
avoided, it is recommended that a suitable catch pan, adequately
drained, be installed under the water heater.

LOCAL INSTALLATION REGULATIONSThis water heater must be installed in accordance with these instructions, local
codes, utility company requirements or, in the absence of local codes, the latest
edition of the National Electrical Code. It is available from some local libraries orcan be purchased from the National Fire Prevention Association, Batterymarch
Park, Quincy, MA 02269 as booklet ANSI/NFPA 70.
LOCATION
This water heater is designed to meet a wide range of applications. It fulfills ademand for a small water heater that can be installed in a limited space. Locate
the water heater in a clean dry area as near as practical to hot water fixtures, orclose to the hot water faucet most frequently used. Place the water heater insuch a manner that the thermostat and element access panels can be removed
to permit inspection and servicing such as removal of elements or checking
controls. The water heater and water lines should be protected from freezing
temperatures. Do not install the water heater in outdoor, unprotected areas.

Installation
1. INSPECT SHIPMENT — Inspect water heater for possible damage.
Check the markings on the rating plate of the water heater to be certain the
power supply corresponds to that for which the water heater is equipped.

3. WATER SUPPLY CONNECTIONS — Refer to Fig. 1 or 2 for suggested
typical installation. The installation of unions or flexible copper connectors
is recommended on the hot and cold water connections so that the water
heater may be easily disconnected for servicing if necessary. The HOT
and COLD water connections are clearly marked and are 3/4” NPT on allmodels. Install a shut-off valve in the cold water line near the water heater.

2. THERMAL EXPANSION — Determine if a check valve exists in
the inlet water line. It may have been installed in the cold waterline as a separate back flow preventer, or it may be part of a pressure reducing valve, water meter or water softener. A check valve
located in the cold water inlet line can cause what is referred toas a ”closed water system”. A cold water inlet line with no checkvalve or back flow prevention device is referred to as an ”open”
water system.
As water is heated, it expands in volume and creates an increasein the pressure within the water system. This action is referred toas ”thermal expansion”. In an ”open” water system, expanding
water which exceeds the capacity of the water heater flows backinto the city main where the pressure is easily dissipated.

IMPORTANT!! Do not apply heat to the hot or cold water supply
fittings. If sweat connections are used, sweat tubing to adapter
before fitting adapter to hot or cold water supply fittings of heater.
Any heat applied to the hot or cold water supply fittings will
permanently damage them.
4. RELIEF VALVE — A new combination pressure and temperature relief
valve, complying with the Standard for Relief Valves and Automatic Gas
Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22, must be
installed in the opening provided and marked for the purpose on thewater heater (Refer to Fig. 1 or 2). No valve of any type should beinstalled between the relief valve and the tank. Local codes shall govern
the installation of relief valves.
The pressure rating of the relief valve must not exceed 150 PSI, themaximum working pressure of the water heater as marked on the ratingplate. The BTUH Rating of the relief valve must not be less than the input
rating of the water heater as indicated on the rating label located on frontof the heater (1 watt = 3.412 BTUH).

A ”closed water system”, however, prevents the expanding
water from flowing back into the main supply line, and the resultof ”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!

Connect the outlet of the relief valve to a suitable open drain so that thedischarge water cannot contact live electrical parts and to eliminate
potential water damage. Piping used should be of a type approved for hot
water distribution. The discharge line must be no smaller than the outlet ofthe valve and must pitch downward from the valve to allow complete
drainage (by gravity) of the relief valve and discharge line. The end of thedischarge line should not be threaded or concealed and should beprotected from freezing. No valve of any type, restriction or reducer
coupling should be installed in the discharge line.

The suggested method of controlling thermal expansion is to install
an expansion tank in the cold water line between the water heaterand the check valve. The expansion tank is designed with an air cushion built in that compresses as the system pressure increases,
thereby relieving the over pressure condition and eliminating the repeated operation of the relief vale. Other methods of controlling
thermal expansion are also available. Contact your installing contractor, water supplier, or plumbing inspector for additional information regarding this subject.

SAFETY PRECAUTIONS
A. Do turn off power to water heater if it has been subjected to overheating, fire, flood or physical damage.

! CAUTION

B. Do Not turn on water heater unless it is filled with water.

Hydrogen gas can be produced in a hot water system served bythis water heater that has not been used for a long period of time
(generally two weeks or more). HYDROGEN GAS IS EXTREMELYFLAMMABLE!! To dissipate such gas and to reduce risk of injury,
it is recommended that the hot water faucet be opened for several
minutes at the kitchen sink before using any electrical applianceconnected to the hot water system. If hydrogen is present, there
will probably be an unusual sound such as air escaping throughthe pipe as the water begins to flow. Do not smoke or use an
open flame near the faucet at the time it is open.

C. Do Not turn on water heater if cold water supply shut-off valve isclosed.
D. If there is any difficulty in understanding or following the OPERATION
or MAINTENANCE instructions, it is recommended that a qualified
person or serviceman perform the work.

1. WATER TEMPERATURE SETTING — The temperature of the water inthe water heater can be regulated by setting the temperature dial of theadjustable surface mounted thermostat(s) located behind the jacket
access panel(s). Dual element heaters have two thermostats. To comply
with safety regulations the thermostat is factory set at 120°F (49°C) or
less where local codes require.

CAUTION!! — Hotter water increases the risk of SCALDING!
This illustration shows shows the temperature adjustment dial used for setting
the water temperature. Refer to Section 1 - Water Temperature Setting, above,for more details and safety instructions regarding water temperature setting.

2. SAFETY CONTROLS — The water heater is equipped with a
combination Thermostat and Temperature Limiting Control (ECO) that is
located behind the “Jacket Access Panel” in contact with the tanksurface. If for any reason the water temperature becomes excessively
high, the Temperature Limiting Control (ECO) breaks the power circuit tothe heating element. Once the control opens, it must be reset manually.

Figure 6. — Thermostat and Protective Cover.

Safety and energy conservation are factors to be considered whenselecting the water temperature setting of the water heater’s thermostat.
The lower the temperature setting the greater the savings in energy andoperating costs.

! CAUTION! DANGER
There is a Hot Water SCALD Potential if the thermostat is set too
high.

The cause of the High Temperature Condition must be investigatedby qualified service personnel and corrective action taken before
placing the water heater in service again.

NOTE: Households with small children or invalids may requirea 120° F(49°C). or lower thermostat setting to prevent contact
with “HOT” water.

To reset Temperature Limiting Control, turn off power to water heater,
remove jacket access panel(s) and insulation. The thermostat

protective cover SHOULD NOT be removed. (Refer to Fig. 6) Press
red “RESET” button. Replace insulation and jacket access panel(s)before turning on power to water heater.

In order to drain water heater, turn off cold water supply, then it isnecessary to open a hot water faucet or lift the handle on the relief valve
to admit air to the tank. Attach a garden hose to the drain valve on thewater heater and direct the stream of water to a drain where it will do nodamage.

3. EMERGENCY INSTRUCTIONS —! WARNING! DANGER

If water heater has been subjected to flood,fire,or physical damage,turn off power and water to water heater. Do not operate the water
heater again until it has been thoroughly checked by qualified
service personnel.

The water drained from the tank may be hot enough to present a
SCALD HAZARD and should be directed to a suitable drain toprevent injury or damage.

4. VACATION AND LONG TIME SHUT-DOWN — If the water heater is toremain idle for an extended period of time, the power and water to thewater heater should be turned off to conserve energy. The water heaterand piping should be drained if they might be subjected to freezing
temperatures.

6. ANODE — This water heater is equipped with an anode rod designed toprolong the life of the glass lined tank. The anode is slowly consumed
cathodically, thereby eliminating or minimizing corrosion of the glass linedtank.

NOTE: Refer to “Hydrogen Gas Caution” in Safety Precautions
Section on page 7.

Water sometimes contains a high sulfate and/or mineral content andtogether with the cathodic protection process can produce a hydrogensulfide or rotten egg odor in the heated water. Chlorination of the watersupply should minimize the problem.

After a very long shut-down period, the water heater’s operation andcontrols should be checked by qualified service personnel. Make certain
the water heater is completely filled before again placing it in operation .

NOTE: Do not remove the anode rod from the water heater’s tank,except for inspection and/or replacement, as operation with theanode rod removed will greatly shorten the life of the glass lined
tank and will exclude warranty coverage.

5. DRAINING HEATER —! CAUTION
Shut off power to water heater before draining water.

Maintenance
Properly maintained, your water heater will provide years of dependable
trouble-free service. It is suggested that a routine preventive maintenanceprogram be established and followed by the user. It is further recommended
that a periodic inspection of the operating controls, heating element and wiring
should be made by service personnel qualified in electric appliance repair.

NOTE: If the temperature and pressure relief valve on the water
heater discharges periodically, this may be due to thermal
expansion in a “Closed” water system. Contact the watersupplier or your plumbing contractor on how to correct this. DO
NOT plug the relief valve outlet.

1. ROUTINE PREVENTATIVE MAINTENANCE
A. Most electrical appliances make some sound when in operation, evenwhen new. If the hissing or singing sound level increases excessively, theelectric heating element may require cleaning. Contact your installer orplumbing contractor to inspect.

D. A water heater’s tank can act as a settling basin for solids suspended in thewater. It is, therefore, not uncommon for hard water deposits to accumulate
in the bottom of the tank. It is suggested that a few quarts of water bedrained from the water heater’s tank every month to clean the tank of these
deposits.

B. The area near the water heater must be kept free of flammable liquids suchas gasoline or paint thinners, adhesives or other combustible materials.

E. Rapid closing of faucets or solenoid valves in automatic water using
appliances can cause a pounding “water hammer” sound. “Water hammer”
can be described as a banging noise heard in a water pipe following anabrupt alteration of the flow with resulting pressure surges. Strategicallylocated risers in the water pipe system can be used to minimize theproblem. Also water hammer arresting devices are usually available fromyour plumber or local plumbing supply store.

C. At least once a year, lift and release the lever handle on the temperaturepressure relief valve, located near the top of the water heater, to makecertain the valve operates freely and allow several gallons to flush throughdischarge line. Make certain the discharged water is directed to an open
drain.

! DANGER

2. ANODE ROD INSPECTION — The anode rod should be removed fromthe water heater’s tank annually for inspection and replaced when morethan 6” of core wire is exposed at either end of the rod. Refer toReplacement Parts List for anode rod location. Make certain cold watersupply is turned off before removing anode rod.

Before manually operating the relief valve, make certain no one
will be exposed to the danger of coming in contact with the hotwater released by this valve. The water may be hot enough tocreate a SCALD hazard. The water released should be directed toa suitable drain to prevent injury or damage.
