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, basements, 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 operation and service.
Keep combustibles such as boxes, magazines, clothes,
etc., away from the water heater area.
Do not use this water heater in conjunction with a spa or
hot tub.
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
suitable indoor drain. Outdoor drains are subject to
freezing temperatures which can obstruct the drain
line. The piping should be at least 3/4”ID and pitched
for proper drainage.
Under no circumstance will the manufacturer or
seller of this water heater be held liable for any
water damage that is caused by your failure to
follow these instructions.
NOTE: The water heater shall be located so it is not
subject to physical damage by moving vehicles or area
flooding.

Water System Piping
Piping Installation
Piping, fi ttings, and valves should be installed according
to the installation drawing (Figure 3). If the indoor installation area is subject to freezing temperatures, the
water piping must be protected by insulation.
Water supply pressure should be around 50 to 60 psi
and should not exceed 80 psi. If this occurs, a pressure
reducing valve should be installed in the cold water inlet
line. This should be placed on the supply to the entire
house in order to maintain equal hot and cold water
pressures.
IMPORTANT: Heat cannot be applied to the water fi ttings
on the heater as they may contain nonmetallic parts.
If solder connections are used, solder the pipe to the
adapter before attaching the adapter to the hot and cold
water fi ttings.
IMPORTANT: Always use a good grade of joint com-
pound and be certain that all fi ttings are drawn up tight.
1. Install the water piping and fitting as shown in
Figure 3. Connect the cold water supply (3/4” NPT)
to the fitting marked “Cold”. Connect the hot water
supply (3/4” NPT) to the fitting marked “Hot”.
IMPORTANT: Some models may contain energy saving
heat traps to prevent the circulation of hot water within
the pipes. Do not remove these inserts.
2. The Installation of dielectric unions in both the hot
and cold water supply lines is recommended for
ease of removing the water heater for service or
replacement.
3. Some local codes may require, and the manufac turer of this water heater recommends,
installing a mixing valve in the domestic hot water
line as shown in Figure 4. These valves reduce the
point-of-use temperature of the hot water by mixing
cold and hot water and are readily available.
Contact a licensed plumber or the local plumbing
authority.
4. If installing the water heater in a closed water
system, install a relief valve or expansion tank in
the cold water line as specified under “Closed
System/Thermal Expansion”.
5. Install a shut-off valve in the cold water inlet line. It
should be located close to the water heater and be
easily accessible. Know the location of this valve
and how to shut off the water to the heater.
6. Install a discharge line from the temperature and
pressure relief valve in the opening marked “T & P
RELIEF VALVE”. Install as specified under
“Temperature and Pressure Relief Valve”.
7. After piping has been properly connected to the
water heater, open the nearest hot water faucet.
Then open the cold water shut off valve and
allow the tank to completely fill with water. To purge
the lines of any excess air and sediment, keep the
hot water faucet open for 3 minutes after a constant
flow of water is obtained. Close the faucet and
check all connections for leaks.

Please note the following:
DO NOT install this water heater with iron piping.
The system should be installed only with piping that
is suitable for potable (drinkable) water such as
copper, CPVC, or polyethylene (PEX).
DO NOT use PVC water piping.
DO NOT use any pumps, valves, or fi ttings that are
not compatible with potable water.
DO NOT use valves that may cause excessive
restriction to water fl ow. Use full-fl ow ball or gate
valves only.
DO NOT use tin-lead solder in potable water lines.
Use 95/5 tin antimony or other equivalent material.
DO NOT tamper with the energy smart module,
electronic thermostat, temperature sensors, heat ing elements, electrical connections, or temperature
and pressure relief valve. Tampering voids all war ranties. Only qualifi ed person should service these
components.
DO NOT use with piping that has been treated with
chromate’s, boiler seal, or other chemicals.
DO NOT add any chemicals to the system piping
which will contaminate the potable water supply.
Closed System/Thermal Expansion
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 system, 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 temperaturepressure relief valve operation: water discharged from the
valve due to excessive pressure build up. The temperature-pressure relief valve is not intended for the constant
relief of thermal expansion. This condition is not covered
under the limited warranty.
A properly-sized thermal expansion tank should be installed 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 thermal expansion tank.

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 certifi 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 developing 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.
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.

T&P Relief Valve and Pipe Insulation:
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.
7. Repeat steps 5 through 6 for the hot water (outlet)
pipe.
8. Add additional sections of pipe insulation as needed.
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).
Note: Solar water heating systems can often supply water
with temperatures exceeding 180° F (82.2° C) and may
result in water heater malfunction.
1. Locate the temperature and pressure relief valve on
the water heater (also known as a T&P Relief Valve,
(Figure 6).
2. Locate the slit running the length of the insulation.
3 Spread this slit open and slip it up under the T&P
Relief Valve (See Figure 6). Apply gentle pressure to
the insulation to ensure it is fully seated on the T&P
Relief Valve. Once sealed, secure the insulation with
a section of duct tape, electrical tape, or equivalent.
IMPORTANT: The insulation or tape must not block
the discharge opening or hinder access to the manual
relief lever. Ensure a discharge pipe is installed into
the T&P valve discharge opening per the instructions
manual.
4. Locate the hot water (outlet) & cold water (inlet) pipes
to the water heater.
5. Locate the slit running the length of a section of pipe
