Location Requirements
Site location
Select a location near the center of the water piping
system, tt must be installed indoors and in a vertical
position on a level surface.
The water heater should be located in an area not
subject to freezing temperatures. Water heaters located
in unconditioned spaces (i.e., attics, 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.
Do not use this water heater in conjunction with a spa
or hot tub.
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.
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. It is
recommended that a suitable drain pan be installed
under the water heater as shown below. This pan is to
3rotect the property from damage which may occur
from normal condensate formation on the tank or
leaks in the tank and pipe connections. The 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"1D
and pitched for proper drainage.
Under no circumstance will the manufacturer be
held liable for any water damage in connection
with this water heater.

Water System Piping
Piping Installation
Piping, fittings, and valves should be installed according
to the installation drawing (Figure 2). If the indoor
installation area is subject to freezing temperatures, the
water piping must be protected by insulation.
Water supply pressure should not exceed 80% of the
working pressure of the water heater. The working
pressure is stated on the water heater's data plate. If
this occurs a pressure limiting valve with a bypass may
need to be installed in the cold water supply 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 fittings
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 fittings.
Important: Always use a good grade of joint compound
and be certain that all fittings are drawn up tight.
1. Install the water piping and fittings as shown in
Figure 2. Connect the cold water supply (3/4 NPT)
to the fitting marked "C". Connect the hot water
supply (3/4 NPT) to the fitting marked "H".
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 unions in both the hot and cold
water supply lines is recommended for ease of
removing the water heater for service or
replacement.
3. The manufacturer of this water heater recommends
installing a tempering valve in the domestic hot
water line as shown in Figures 3 and 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.
.
.
Install a temperature and pressure relief valve and
discharge line in the opening marked "T & P
RELIEF VALVE". Install as specified under
"Temperature and Pressure Relief Valve."
After piping has been properly connected to the
water heater, open the nearest hot water faucet 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 new piping
that is suitable for potable (drinkable) water such as
copper, CPVC, or polybutylene. DO NOT use PVC
water piping.
DO NOT use any pumps, valves, or fittings that are
not compatible with potable water.
DO NOT use valves that may cause excessive
restriction to water flow. Use full flow ball or gate
valves only.
DO NOT use 50/50 tin-lead solder (or any lead
based solder) in potable water lines. Use 95/5 tin-
antimony or other equivalent material.
DO NOT tamper with the electronic control board,
temperature sensors, heating elements, electrical
connections, or temperature and pressure relief
valve. Tampering voids all warranties. Only qualified
technicians should service these components.
DO NOT use with piping that has been treated with
chromates, 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
Periodic discharge of the temperature and pressure
relief valve may be due to thermal expansion in a
closed water supply system. The water utility supply
meter may contain a check valve, backfiow preventer,
or water pressure reducing valve. This will create a
closed water system. During the heating cycle of the
water heater, the water expands causing pressure
inside the water heater to increase. This may cause the
temperature and pressure relief valve to discharge
small quantities of hot water. To prevent this from
happening, there are two recommendations:
1. Install a diaphragm-type expansion tank that is
suitable for potable water on the cold water supply
line. The expansion tank must have a minimum
capacity of 1.5 U.S. gallons for every 50 gallons of
stored water.
.Install a 125 PSI pressure relief valve in the cold
water supply line. Make sure the discharge of this
valve is directed to an open drain and protected
from freezing. Contact the local water supplier or
plumbing inspector for information on how to
control this situation. Do not plug the temperature
and pressure relief valve.
Temperature and Pressure
Relief Valve
Explosion Hazard
If the temperature and pressure relief
valve is dripping or leaking, have a
licensed plumber repair it.
Do not plug valve.
Do not remove valve.
Failure to follow these instructions can
result in death or explosion.

For protection against excessive pressures and
tern peratures, a tern peratu re and pressu re relief valve
must be installed in the opening marked "T & P RELIEF
VALVE" (See Figure 5).
Caution: To reduce the risk of excessive pressures and
temperatures in this water heater, install temperature
and pressure relief 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 the production of listed equipment
or materials, as meeting the requirements for Relief
Valves and Automatic Shutoff Devices for Hot Water
Supply Systems, ANSI 721.22 -1986. This valve must
be marked with the maximum set pressure not to
exceed the marked maximum working pressure of the
water heater. Install the valve into an opening provided
and marked for this purpose in the water heater, and
orient it or provide tubing so that any discharge from the
valve exits only within 6 inches above, or at any
distance below, the structural floor, and does not
contact any live electrical part. The discharge opening
must not be blocked or reduced in size under any
circumstance.

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.
The Discharge Line:
_- Must terminate a maximum of 6 inches above a
floor drain or external to the building.
_- Must be capable of withstanding 250°F (121°C)
without distortion.
_. Must be installed to allow complete drainage of
both the valve and 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°E A tempering valve or other temperature
limiting valve must be installed in the water supply line
to limit the supply temperature to 120°R
Note: Solar water heating systems can often supply
water with temperatures exceeding 180°F and may
result in water heater malfunction.

3. Carefully read and understand the section, "Water
Temperature Regulation", of this manual and adjust
the temperature control knob to the desired setting.
4. Read the section, "Operating Mode Descriptions"
on page 10 and select the desired operating mode.
5. After the tank is completely filled with water, turn on
power to the water heater. Note: The water heater
performs self-diagnostics that takes approximately
10 minutes. During this time, the elements may not
be energized. If a failure is detected, the Diagnostic
Light flashes the related failure code. See page 14
for "Diagnostic Code Chart."
Important: Operation of this water heater without
access doors or insulation could result in much higher
water temperatures than the desired set point,
increasing the risk of scald injury. Do not operate
water heater with the access doors or insulation
removed, r'-m
Access Doors
Important: Do not attempt to operate this water heater
if the temperature sensor(s), electronic control board, or
surrounding insulation has been exposed to water in
any way. Immediately call a qualified service technician
to inspect the water heater and replace any
temperature sensor(s), electronic control board, or
insulation that has been exposed to water. Do not
attempt to repair these parts. Water heaters subjected
to flood conditions or any time the temperature
sensor(s) or electronic control board have been
submerged in water require replacement of the entire
water heater.
Safety Shut-off
This water heater is equipped with a high limit control
switch that is designed to shut off the power to the
elements if the water temperature exceeds170°F
(77°C). Use the diagnostic control chart on page 14 to
help determine the cause of the high limit shut-off. After
the cause has been corrected, reset the control as
directed under "Reset Function" on page 10.
Water Temperatu re
Regulation
Water temperature over 125°F can cause
severe burns instantly or death from
scalds.
Children, disabled, and elderly are at
highest risk of being scalded.
See the instruction manual before setting
temperature at water heater.
Feel water before bathing or showering.
Temperature limiting valves are available.
The temperature control is adjusted to a setting of
120°F or lower when it is shipped from the factory.
Water temperature can be regulated by adjusting the
temperature control system to the preferred setting as
shown in "Operating the Temperature Control System."
The recommended starting point is 120°F. There is a
hot water scald potential if the temperature control
is set too high.
Important: Adjusting the temperature past 120°F on the
temperature control will increase the risk of scald injury.
Hot water can produce first degree burns within:
120°F (49°C) more than 5 minutes
130°F (54°C) at 20 seconds
140°F (60°C) at 3 seconds
150°F (66°C) at 1-1/2 seconds
160°F (71°C) at less than 1 second

Water Temperature Adjustment
The water temperature can be adjusted from 80°F to 150°F. Use the temperature control knob to change to the
desired temperature.
Operating Mode Descriptions
1. Smart Mode - The controller operates the water heater to maintain the customer's selected temperature.
2. Energy Smart Mode - The controller adjusts the water temperature to lowest temperature required to meet the
household demands. This mode minimizes operating costs. The controller will not adjust temperature higher than
customer's selected set point or lower than 115°E
3. Low Temperature Mode - The controller limits the water temperature to 120°F or at the temperature selected
whichever is lower. See page 9 for more information on scalds.
4. Vacation/Cabin Mode - The controller adjusts the water temperature to approximately 50°F. This mode is
recommended when the water heater is not in use for a long period of time. This effectively turns the water heater
off and prevents the water from freezing.
