there shall be no materials stored against the water heater and proper care  
shall be taken to avoid unnecessary contact (especially by children) with  
the water heater. UNDER NO CIRCUMSTANCES SHALL FLAMMABLE  
MATERIALS, SUCH AS GASOLINE OR PAINT THINNER BE USED OR  
STORED IN THE VICINITY OF THIS WATER HEATER OR ANY  
LOCATION FROM WHICH FUMES COULD REACH THE WATER  
HEATER.  
This water heater MUST be installed indoors out of the wind and  
weather.  
This water heater shall NOT be installed in any location where gasoline  
or flammable vapors are likely to be present, unless the installation is  
such to eliminate the probable ignition of gasoline or flammable  
vapors.  
The location this water heater is to be installed is of utmost importance.  
Before installing this water heater, consult the installation section of these  
instructions. After reading these installation and operating instructions,  
select a location for the water heater where the floor is level and is easily  
accessible to a power supply and water connections. It is recommended  
that the water heater be located near the center of greatest hot water usage  
to prevent heat loss through the pipes.

Locating The Water Heater continued-  
DO NOT locate the water heater where water lines could be subjected  
to freezing temperatures. Locate the water heater so that access  
panels and drain valves are accessible. Some models are not equipped  
with a drain valve. For those models, install a drain tee in the cold water inlet  
as close as practical to the water heater.  
Water heater corrosion and component failure can be caused by the heating  
and breakdown of airborne chemical vapors. Examples of some typical  
compounds that are potentially corrosive are: spray can propellants, cleaning  
solvents, refrigerator and air conditioning refrigerants, swimming pool  
chemicals, calcium or sodium chloride, waxes and process chemicals.  
These materials are corrosive at very low concentration levels with little or no  
odor to reveal their presence.  
NOTE: DAMAGE TO THE WATER HEATER CAUSED BY EXPOSURE TO  
CORROSIVE VAPORS IS NOT COVERED BY THE WARRANTY. DO  
NOT OPERATE THE WATER HEATER IF EXPOSURE HAS OR WILL  
OCCUR. DO NOT STORE ANY POTENTIALLY CORROSIVE  
COMPOUNDS IN THE VICINITY OF THE WATER HEATER.  
This water heater must be located in an area where leakage of the tank or  
water line connections and the combination temperature and pressure relief  
valve will not result in damage to the area adjacent to the water heater or to  
lower floors of the structure. When such locations cannot be avoided, a  
suitable drain pan must be installed under the water heater. The drain pan  
must have a minimum length and width of at least 4 in. (10.2 cm) greater  
than the diameter of the water heater. The drain pan, as described above,  
can be purchased from your plumbing professional. The drain pan must be  
piped to an adequate drain. The piping must be pitched for proper drainage.  
To comply with NSF requirements this water heater is to be:  
a) Sealed to the floor with sealant, in a smooth and easily cleanable  
way, or  
b) Installed with an optional leg kit that includes legs and/or extensions  
that provide a minimum clearance of 6” beneath the water heater.  
Note: For California installation this water heater must be braced,  
anchored, or strapped to avoid falling or moving during an  
earthquake. See instructions for correct installation procedures.  
Instructions may be obtained from California Office of the State  
Architect, 400 P Street, Sacramento, CA 95814.

Water Connections  
NOTE: BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE  
MAIN WATER SUPPLY VALVE.  
After shutting the main water supply valve, open a faucet to relieve the water  
line pressure to prevent any water from leaking out of the pipes while making  
the water connections to the water heater. After the pressure has been  
relieved, close the faucet. The COLD water inlet and HOT water outlet are  
identified on top of the water heater. The fittings at the cold water inlet and  
hot water outlet are dielectric waterway fittings with 3/4” NPT tapered male  
threads. Make the proper plumbing connections between the water heater  
and the plumbing system in the house. Install a shut-off valve in the cold  
water supply line.  
CAUTION  
If sweat fittings are to be used, DO NOT apply heat to the nipples on top  
of the water heater. Sweat the tubing to the adapter before fitting the  
adapter to the water connections. It is imperative that heat is not applied  
to the nipples containing a plastic liner.  
IMPORTANT  
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4”  
TEMPERATURE-PRESSURE RELIEF VALVE WILL RELEASE THE  
MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM  
EXCESSIVE TEMPERATURE AND PRESSURES.  
If this water heater is installed in a closed water supply system, such as the  
one having a back-flow preventer in the cold water supply, provisions shall  
be made to control thermal expansion. DO NOT operate this water heater in  
a closed system without provisions for controlling thermal expansion. Your  
water supplier or local plumbing inspector should be contacted on how to  
control this situation.  
After installation of the water lines, open the main water supply valve and fill  
the water heater. While the water heater is filling, open several hot water  
faucets to allow air to escape from the water system. When a steady stream  
of water flows through the faucets, close them and check all water  
connections for possible leaks. NEVER OPERATE THE WATER HEATER  
WITHOUT FIRST BEING CERTAIN IT IS FILLED WITH WATER.

Water Connections continued-  
WARNING  
For protection against excessive temperatures and pressure, install  
temperature and pressure protective equipment required by local codes,  
but not less than a combination temperature and pressure relief valve  
certified by a nationally recognized testing laboratory that maintains  
periodic inspection of production of listed equipment or materials, as  
meeting the Requirements for Relief Valves and Automatic Gas Shutoff  
Devices for Hot Water Supply Systems, ANSI Z21.22, and the Standard  
CAN1-4.4 Temperature, Pressure, Temperature and Pressure Relief  
Valves and Vacuum Relief Valves. The combination temperature and  
pressure relief valve shall be marked with a maximum set pressure, not to  
exceed the maximum working pressure of the water heater. The  
combination temperature and pressure relief valve shall also have an  
hourly rated temperature steam BTU discharge capacity not less than the  
hourly input rating of the water heater.  
Install the combination temperature and pressure relief valve into the  
opening provided and marked for this purpose on the water heater  
Note: Some models may already be equipped or supplied with a  
combination temperature and pressure relief valve. Verify that the  
combination temperature and pressure relief valve complies with local  
codes. If the combination temperature and pressure relief valve does not  
comply with local codes, replace it with one that does. Follow the  
installation instructions above on this page.  
Install a discharge line so that water discharged from the combination  
temperature and pressure relief valve will exit within six (6) inches (15.3  
cm) above, or any distance below the structural floor and cannot contact  
any live electrical part. The discharge line is to be installed to allow for  
complete drainage of both the temperature and pressure relief valve and  
the discharge line. The discharge opening must not be subjected to  
blockage or freezing. DO NOT thread, plug or cap the discharge line. It is  
recommended that a minimum of four (4) inches (10.2 cm) be provided on  
the side of the water heater for servicing and maintenance of the  
combination temperature and pressure relief valve.  
Do not place a valve between the combination temperature and pressure  
relief valve and the tank.

Water Connections continued-  
WARNING  
Hydrogen gas can be produced in a hot water system served by this  
water heater that has not been used for a long period of time  
(generally two weeks or more). Hydrogen gas is extremely  
flammable. To reduce the risk of injury under these conditions, it is  
recommended that the hot water faucet be opened for several  
minutes at the kitchen sink before using any electrical appliance  
connected to the hot water system. If hydrogen is present, there will  
probably be an unusual sound such as air escaping through the pipe  
as the water begins to flow. There should be no smoking or open  
flame near the faucet at the time it is open.  
CAUTION  
INCREASING THE THERMOSTAT SETTING ABOVE THE PRESET  
TEMPERATURE MAY CAUSE SEVERE BURNS AND CONSUME  
EXCESSIVE ENERGY. HOTTER WATER INCREASES THE RISK OF  
SCALD INJURY.

Water Connections continued-  
This water heater can deliver scalding temperature water at any faucet in the  
system. Be careful whenever using hot water to avoid scalding injury.  
Certain appliances, such as dishwashers and automatic clothes washers,  
may require increased temperature water. By setting the thermostat on this  
water heater to obtain increased temperature water required by these  
appliances, you may create the potential for scald injury. To protect against  
injury, you should install an ASSE approved mixing valve in the water  
system. This valve will reduce point of discharge temperature by mixing cold  
and hot water in branch supply lines. Such valves are available from the  
manufacturer of this water heater or a local plumbing supplier. Please  
consult with a plumbing professional.

Electrical Connections  
Before any electrical connections are made, be sure that the water heater is  
full of water and that the manual shut-off valve in the cold water supply line is  
open. Check the rating plate and wiring diagram before proceeding. This  
electric water heater was built and wired in accordance with the Underwriters  
Laboratories testing approvals requirements. The temperature limiting  
device is of the manual reset, trip-free type and has been factory installed to  
interrupt all ungrounded power supply conductors in the event of thermostat  
failure. Thermostats are factory set and wired in accordance with the wiring  
diagram fastened to the inside of the top access panel. The plumbing  
supplier in your area ordered this heater wired at the factory to comply with  
existing area codes, but local utility codes may require or allow other  
circuitry. Consult your local power company to determine the correct  
electrical hook-up in order to meet local utility and building codes and in  
order to obtain the most economical rates. Also check to find out if you are  
required to obtain a permit before starting the installation. The following  
chart shows the recommended fuse size for the maximum water heater  
wattage. The maximum wattage and rated voltage are shown on the water  
heater data plate. The water heater must be well grounded. A green ground  
screw is provided at the electrical connection point for connecting a ground

GENERAL OPERATION  
Before closing the switch to allow electric current to flow to the  
water heater, make certain that the water heater is full of water and  
that the cold water inlet valve is open. Complete failure of the  
heating element(s) will result if they are not totally immersed in  
water at all times. Failure of the element(s) due to dry-firing is not  
covered by warranty.  
When the switch is closed, the operation of this electric water heater is  
automatic. The thermostats are preset to the “HOT” setting to provide a  
water temperature of approximately 120°F (49°C) to reduce the risk of scald  
injury.  
CAUTION  
Scalding may occur within five (5) seconds at a temperature setting of  
140°F (60°C).  
Care must be taken whenever using hot water to avoid scalding injury.  
Certain appliances require high temperature hot water (such as dishwashers  
and automatic clothes washers).  
TO FILL THE WATER HEATER  
1. Close the water heater drain valve (if provided) by inserting a standard  
flat head screwdriver into the slot and turning clockwise.  
2. Open the cold water supply shut-off valve.  
3. Open several hot water faucets to allow air to escape from the system.  
4. When a steady stream of water flows from the faucets, the water heater  
is filled. Close the faucets and check for water leaks at the water heater  
drain valve, combination temperature and pressure relief valve and the  
hot and cold water connections.  
TO DRAIN THE WATER HEATER  
Should it become necessary to completely drain the water heater, make sure  
you follow the steps below:  
1. Disconnect the power supply to the water heater. Consult the plumbing  
professional or electric company in your area for service.  
2. Close the cold water supply shut-off valve.  
3. Open the drain valve (if provided) on the water heater by inserting a  
standard flat head screwdriver into the slot and turning counter-  
clockwise. The drain valve has threads on the end that will allow  
connection of a standard hose coupling. For those models not equipped  
with a drain valve, disconnect cold water inlet piping at a convenient  
connection location as close to an adequate drain as possible.  
CAUTION! THIS WATER MAY BE HOT.  
4. Open a hot water faucet to allow air to enter the system.  
To refill the water heater, refer to “TO FILL THE WATER HEATER.”

The temperature of the water can be changed by adjusting the thermostat(s).  
Before any work is done on the water heater, disconnect all power to the  
water heater by opening the switch at the main electrical circuit breaker or  
fuse box. Remove the access panels or front panel on table tops, fold the  
insulation outward away from the controls. Set the thermostat(s) to the  
desired water temperature using a screwdriver to move the thermostat dial.  
The thermostat has been factory preset to approximately 120°F (49°C).  
Rotate the temperature dial clockwise to increase water temperature.  
Replace the insulation making sure that the controls are well covered and  
that the plastic terminal shield has not been displaced; replace the access  
panel. The water heater is now ready for operation and the main switch can  
be closed.  
Figure 4  
DANGER  
Hotter water increases the risk of scald injury. Scalding may occur within  
five (5) seconds at a temperature setting of 140°F (60°C). To protect  
against hot water injury, install an ASSE approved mixing valve in the water  
system. This valve will reduce point of discharge water temperatures by  
mixing cold and hot water in branch water lines. A licensed plumbing  
professional or local plumbing authority should be consulted.  
Note: This water heater is equipped with an energy cut out device to  
prevent overheating. Should overheating occur, turn off the electrical  
supply to the water heater and contact a qualified service technician.

MAINTENANCE  
IMPORTANT  
The water heater should be inspected at a minimum of annually by a  
qualified service technician for damaged components. DO NOT operate  
this water heater if any part is found damaged.  
Shut off the electric power whenever the water supply to the water heater is  
off. Shut off the electric power and water supply, drain the water heater  
completely to prevent freezing whenever the building is left unoccupied  
during the cold weather months. In order to insure efficient operation and  
long tank life, drain the water heater at least once a month through the drain  
valve until the water runs clear. Failure to do this may result in noisy  
operation and lime and sediment buildup in the bottom of the tank. Check  
the temperature-pressure relief valve to insure that the valve has not  
become encrusted with lime. Lift the lever at the top of the valve several  
times until the valve seats properly without leaking and operates freely.  
WARNING  
When lifting lever of temperature-pressure relief valve, hot water will be  
released under pressure. Be certain that any released water does not  
result in bodily injury or property damage. The magnesium anode rod  
should be inspected periodically and replaced when necessary to prolong  
tank life.  
The following maintenance should be performed by a qualified service  
technician at the minimum periodic intervals suggested below. In some  
installations, the maintenance interval may be more frequent depending on  
the amount of use and the operating conditions of the water heater. Regular  
inspection and maintenance of the water heater will help to insure safe and  
reliable operation.  
1. Annually, check the operation of the thermostat(s).  
2. Bi-annually, check the seal around the heating elements for leaks. If there  
is any sign of leaking, disconnect the power supply to the water heater  
and contact the plumbing professional that installed this water heater or a  
qualified service technician.  
16  
 
Maintenance continued-  
3. At least once a year, check the combination temperature and pressure  
relief valve to insure that the valve has not become encrusted with lime.  
Lift the lever at the top of the temperature-pressure relief valve several  
times until the valve seats properly without leaking and operates freely.  
WARNING  
When lifting lever of temperature-pressure relief valve, hot water will be  
released under pressure. Be certain that any released water does not  
result in bodily injury or property damage.  
4. If the combination temperature and pressure relief valve on the appliance  
discharges periodically, this may be due to thermal expansion in a closed  
water supply system. Contact the water supplier or local plumbing  
inspector on how to correct this situation. Do not plug the combination  
temperature and pressure relief valve outlet for any reason.  
5. Monthly, drain off a gallon of water from the water heater to remove silt  
and sediment.  
WARNING! THIS WATER MAY BE HOT.  
6. A combination sacrificial anode rod/hot water outlet nipple has been  
installed to extend tank life. The anode rod should be inspected  
periodically (every 2 years) and replaced when necessary to prolong tank  
life. Water conditions in your area will influence the time interval for  
inspection and replacement of the anode rod. Contact the plumbing  
professional who installed the water heater or the manufacturer listed on  
the rating plate for anode replacement information. The use of a water  
softener may increase the speed of anode consumption. More frequent  
inspection of the anode is needed when using softened (or phosphate  
treated) water.  
CAUTION  
FOR YOUR SAFETY, DO NOT ATTEMPT TO REPAIR THERMOSTAT(S),  
HEATING ELEMENTS, OR ELECTRICAL WIRING. REFER SUCH  
REPAIRS TO A QUALIFIED SERVICE TECHNICIAN.
