Location Requirements  
Site location  
Select a location near the center of the water piping  
system. It must be installed indoors and in a vertical  
position on a level surface, in an area where water  
leakage will not cause consequential damage.  
NOTE: Local codes and requirements in your area may  
require the water heater to be installed such that the  
bottom element is elevated from the floor at least 18  
inches.  
The water heater should be located in an area not  
subject to freezing temperatures. Water heaters located  
in unconditioned spaces (i.e., attics, garages, base-  
ments, etc.) may require the water piping and drain  
piping to be insulated to protect against freezing. The  
drain and controls must be easily accessible for opera-  
tion and service.  
NOTE: The water heater shall be located so it is not  
subject to physical damage by moving vehicles or area  
flooding.

IMPORTANT: The water heater should be located in  
an area where leakage of the tank or connections will  
not result in damage to the area adjacent to the water  
heater or to lower floors of the structure. Due to the  
normal corrosive action of the water, the tank will  
eventually leak after an extended period of time.  
Also, any external plumbing leak, including those  
from improper installation, may cause early  
failure of the water tank due to corrosion if not  
repaired. If the homeowner is uncomfortable with  
making the repair, a qualified person should be  
contacted. A suitable metal drain pan should be  
installed under the water heater as shown below. This  
metal drain pan is to protect the property from damage  
which may occur from normal condensate formation  
on the tank or leaks in the tank and pipe connections.  
The metal drain pan must limit the water level to a  
maximum depth of 2-1/2 inches and be two inches  
wider than the heater and piped to an adequate drain.  
Locate the water heater near a

Typically, a closed system includes a pressure reducing  
valve (PRV) on the cold water inlet (supply line). As water  
is heated, it expands (thermal expansion). In a closed sys-  
tem, the volume of water will grow. As the volume of water  
grows, there will be a corresponding increase in water  
pressure due to thermal expansion. Thermal expansion  
can cause premature tank failure (leakage). This type of  
failure is not covered under the limited warranty. Thermal  
expansion can also cause intermittent temperature-  
pressure relief valve operation: water discharged from the  
valve due to excessive pressure build up. The tempera-  
ture-pressure relief valve is not intended for the constant  
relief of thermal expansion. This condition is not covered  
under the limited warranty.

For protection against excessive pressures and  
temperatures, a temperature and pressure relief valve  
must be installed in the opening marked “T&P RELIEF  
VALVE” (See Figure 5). This valve must be design certi-  
ed by a nationally recognized testing laboratory that  
maintains periodic inspection of the production of listed  
equipment or materials as meeting the requirements  
for Relief Valves for Hot Water Supply Systems, ANSI  
Z21.22. The function of the temperature and pressure  
relief valve is to discharge water in large quantities in the  
event of excessive temperature or pressure develop-  
ing in the water heater. The valve’s relief pressure must  
not exceed the working pressure of the water heater as  
stated on the rating plate.  
A properly-sized thermal expansion tank should be in-  
stalled on all closed systems to control the harmful effects  
of thermal expansion. Contact a plumbing service agency  
or your retail supplier regarding the installation of a ther-  
mal expansion tank.

IMPORTANT: Only a new temperature and pressure  
relief valve should be used with your water heater. Do  
not use an old or existing valve as it may be damaged or  
not adequate for the working pressure of the new water  
heater. Do not place any valve between the relief valve  
and the tank.  
A thermal expansion tank can help prevent damage to the  
water heater and other appliances (i.e.: washing machine,  
ice maker, dishwasher, etc.).  
IMPORTANT: Do not plug or remove the temperature and  
pressure relief valve (T&P valve).

6. Spread the slit open and slip the insulation over  
the cold water (inlet) pipe. Apply gentle pressure  
along the length of the insulation to ensure it is fully  
seated around the pipe. Also ensure that the base of  
insulation is flush with the water heater. Once seated,  
secure the insulation with duct tape, electrical tape, or  
equivalent.  
The Temperature & Pressure Relief Valve:  
Must be connected to an adequate discharge line.  
Must not be in contact with any electrical part.  
Must not be rated higher than the working pressure  
shown on the data plate of the water heater.  
7. Repeat steps 5 through 6 for the hot water (outlet)  
pipe.  
8. Add additional sections of pipe insulation as needed.  
The Discharge Line:  
Must not be smaller than the pipe size of the relief  
valve or have any reducing coupling installed in the  
discharge line.  
Must not be capped, blocked, plugged, or contain  
any valve between the relief valve and the end of  
the discharge line.  
Solar Installation  
If this water heater is used as a solar storage heater or  
as a backup for the solar system, the water supply  
temperatures to the water heater tank may be in excess  
of 120° F (48.8° C). A mixing valve or other temperature  
limiting valve must be installed in the water supply line to  
limit the supply temperature to 120° F (48.8° C).  
Must terminate a maximum of six inches above a  
oor drain or external to the building. In cold climates,  
it is recommended that the discharge pipe be termi-  
nated at an adequate drain inside the building.  
Must be capable of withstanding 250° F (121°C)  
without distortion.  
Note: Solar water heating systems can often supply water  
with temperatures exceeding 180° F (82.2° C) and may  
result in water heater malfunction.  
Must be installed to allow complete drainage of  
both the valve and discharge line.  
T&P Relief Valve and Pipe Insulation:  
Electrical Requirements  
1. Locate the temperature and pressure relief valve on  
the water heater (also known as a T&P Relief Valve,  
(Figure 6).

Safety Shut-Off  
(U.S. Government Memorandum, C.P.S.C., Peter L. Armstrong, Sept. 15,1978)  
This water heater is designed to automatically shut-off in  
the event that the water temperature exceeds 180° F  
(82.2° C). A temperature limit switch, or ECO (Energy Cut  
Off), is used to shut off the power to the system if the wa-  
ter temperature exceeds 180° F or 82.2° C. The ECO can  
be reset by rmly pushing in the red reset button located  
on the electronic thermostat (see Figure 10A on page 12).  
If the ECO continues to shut-off the water heater contact a  
qualied person.  
When leaving your home for extended periods (vaca-  
tions, etc.) set the water heater to Vacation Mode. See  
“Adjusting the Energy Smart® Module/Operational Modes”  
section. This will maintain the water at low temperatures  
with minimum energy losses and prevent the tank from  
freezing during cold weather.  
NOTE: When returning from an extended stay remember  
to set the water heater back to the desired Operational  
Mode.

Electrical Shock Hazard  
Do not remove the plactic  
guard from over wiring.  
Do not touch electrical wiring.  
The Energy Smart® Module (ESM) is intended to serve  
as the primary interface for operating the water heater;  
however, the Electronic Thermostat (ET) may control the  
water heater in the absence of the Energy Smart® Module  
(ESM).  
Failure to do so can result in  
death or electrical shock.  
Figure 10A  
The Electronic Thermostat consists of an electronics box  
that contains a low voltage power supply, the thermostat  
set point knob, relays to switch between the upper and  
lower heating elements, one control thermistor, a connec-  
tor for the lower element control thermistor, microelectron-  
ics to convert the thermistor signals and perform switch-  
ing and other logic functions, and a connector to tie the  
Electronic Thermostat (ET) to the Energy Smart® Module  
(ESM) located on the front of the water heater jacket. The  
majority of the self-diagnostics are located in the Electronic  
Thermostat (ET), including the dry-re protection intelli-  
gence. The thermostat circuit is designed so that when the  
upper heating element calls for heat, the power is directed  
to that element even if the lower element is also calling for  
heat.

Smart Grid Technology  
The electric Smart Grid will enable signicant improvements in electric power reliability and quality through reduction of  
peak power demand, while providing consumers the knowledge and ability to manage their energy consumption and utility  
costs.  
According to the Department of Energy (DOE), since  
1982 the growth in peak electricity demand has  
exceeded power transmission growth. This has caused  
more frequent blackouts and service interruptions, as  
well as an increase in the costly reserve capacity the  
power grid requires to meet higher peak demands.  
The increased demand for electrical power across the  
nation has also led to higher peak utility costs.  
WARNING  
Disconnect power before  
servicing.  
Replace all parts and panels  
before operating.  
Failure to do so can result in  
death or electric shock.  
Electric Shock Hazard  
Smart appliances are one way to help mitigate this  
problem. By using advanced digital communication  
technologies, smart appliances will be able to  
communicate with local power company or home  
energy management systems, and react accordingly  
to save energy and money. For example, during peak  
demand periods the water heater may pause or delay  
its power consumption and thus reduce the load on the  
smart utility grid. Additionally, smart appliances will also  
communicate with consumers to let them know how  
much energy they are consuming. This will eventually  
allow consumers to control their appliances, manage  
energy usage, and to ultimately save money.

Operational Conditions  
Anode Rod/Water Odor  
Water Heater Sounds  
Each water heater contains at least one anode rod,  
which will slowly deplete (due to electrolysis) prolonging  
the life of the water heater by protecting the glass-lined  
tank from corrosion. Adverse water quality, hotter water  
temperatures, high hot water usage, hydronic heating de-  
vices, and water softening methods can increase the rate  
of anode rod depletion. Once the anode rod is depleted,  
the tank will start to corrode, eventually developing a leak.  
During the normal operation of the water heater,  
sounds or noises may be heard. These noises are  
common and may result from the following:  
1. Normal expansion and contraction of metal parts  
during periods of heat-up and cool-down.  
2. Sediment buildup in the tank bottom will create  
varying amounts of noise and may cause  
premature tank failure. Drain and ush the tank as  
directed under “Draining and Flushing”.  
Certain water conditions will cause a reaction between the  
anode rod and the water. The most common complaint  
associated with the anode rod is a “rotten egg smell”  
produced from the presence of hydrogen sulde gas dis-  
solved in the water. CAUTION: Do not remove this rod  
permanently as it will void any warranties. A special anode  
rod may be available if water odor or discoloration occurs.  
NOTE: this rod may reduce but not eliminate water odor  
problems. The water supply system may require special  
ltration equipment from a water conditioning company to  
successfully eliminate all water odor problems.  
Stacking  
Certain water usage patterns can cause the water tem-  
perature to exceed the thermostat setting. This is known  
as “Stacking”.  
Stacking occurs when a series of short draws of hot  
water (3 gallons or less) are taken from the water heater  
tank. This causes increased cycling of the heater ele-  
ments and can result in increased water temperatures at  
the hot water outlet. An anti-scald device is recommended  
in the hot water supply line to reduce the risk of scald  
injury. Use of a mixing valve is encouraged.  
Articially softened water is exceedingly corrosive be-  
cause the process substitutes sodium ions for magne-  
sium and calcium ions. The use of a water softener may  
decrease the life of the water heater tank.  
The anode rod should be inspected after a maximum of  
three years and annually thereafter until the condition of  
the anode rod dictates its replacement. NOTE: articially  
softened water requires the anode rod to be inspected  
annually.  
The following are typical (but not all) signs of a depleted  
anode rod:  
• The majority of the rods diameter is less than 3/8”.  
• Signicant sections of the support wire (approx. 1/3 or  
more of the anode rod’s length) are visible.  
If the anode rod show signs of either or both it should be  
replaced (see Figure 11). NOTE: Whether re-installing or  
replacing the anode rod, check for any leaks and immedi-  
ately correct if found.

instructions, you should not proceed but have a qualied person perform the maintenance of this water heater.  
Temperature and Pressure  
Relief Valve  
Draining and Flushing  
It is recommended that the tank be drained and ushed  
every 6 months to remove sediment which may buildup  
during operation. The water heater should be drained if  
being shut down during freezing temperatures. To drain  
the tank, perform the following steps:  
Explosion Hazard  
1. Turn off the power to water heater.  
2. Open a nearby hot water faucet until the water is no  
longer hot.  
Temperature-pressure relief  
valve must comply with ANSI  
Z21.22-CSA 4.4 and ASME  
code.  
3. Close the cold water inlet valve.  
4. Connect a hose to the drain valve and terminate it  
to an adequate drain or external to the building.  
• Properly sized temperature-  
pressure relief valve must be  
installed in opening provided.  
5. Open the water heater drain valve and allow all the  
water to drain from the tank. Flush the tank with  
water as needed to remove sediment.  
• Can result in overheating  
and excessive tank pressure.  
6. Close the drain valve and rell the tank (open the cold  
water inlet valve), and restart the heater as directed  
in this manual. CAUTION: Do not turn on power to  
the water heater unless it is completely lled with  
water. To ensure that the tank is full, open a hot water  
faucet and allow water to run until the air is purged  
and the water ows uninterrupted from the  
faucet.  
• Can cause serious injury or  
death.  
Manually operate the temperature and pressure relief  
valve at least once a year to make sure it is working  
properly. To prevent water  
damage, the valve must  
be properly connected to  
a discharge line which  
terminates at an adequate  
drain.
