Installing the water heater
The location chosen for the water heater must take into consideration the following:
Local Installation Regulations
This water heater must be installed
in accordance with these instructions,
local codes, utility 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 or can be purchased from the
National Fire Protection Association,
Batterymarch Park, Quincy, MA 02269
as booklet ANSI/NFPA 70.
Canadian installations should refer to
CSA22.1, a copy can be purchased
from the Canadian Standards
Association, 5050 Spectrum Way,
Mississauga,ONT L4W 5N6
Location
NOTICE: If air
temperature in
installed location
drops more than
15°F (8°C) during
heating, air circulation
is insufficient for
efficient operation.
Utilize ducting to
direct cold exhaust air
to another location.
NOTICE: Auxiliary
drain pan MUST
conform to local
codes.
Drain Pan Kits
are available from
the store where
the water heater
was purchased, or
any water heater
distributor.
Drain Pan should not
obstruct cold inlet or
drain valve.
! CAUTION: The water heater
should not be located in an area
where leakage of the 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 drain
pan, adequately drained, be installed
under the water heater.
NOTICE: Installation in a confined
space will lead to higher power
consumption if adequate ventilation
is not provided.
It is recommended that the hybrid
water heater be installed where ambient
temperatures DO NOT exceed 145°F
(63°C).
Insufficient air exchange will result in
increased energy consumption levels.
Locate the water heater in a clean dry
area as near as practical to the area of
greatest heated water demand. Long
un-insulated hot water lines can waste
energy and water.
Place the water heater in such a
manner that the thermistor 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.
Make certain the floor underneath
the water heater is strong enough to
sufficiently support the weight of the
water heater once it is filled with water.
For installation on floors other than
concrete, the floor isolation kit is
recommended to minimize vibrations.

Inspect Shipment
Inspect the water heater for possible damage. Check the markings on the rating
plate of the water heater to be certain the power supply corresponds to the water
heater requirements. Rating plate is located on front of water heater.
Refrigerant
This Hybrid Water Heater is factory charged with an environmentally friendly,
non-chlorinated refrigerant, R134A. This refrigerant has zero ozone depletion
potential.
5
Installing the water heater
Thermal Expansion
Determine if a check valve exists in the
inlet water line. Check with your local
water utility. It may have been installed in
the cold water line 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 to as a “closed
water system”. A cold water inlet line with
no check valve or back flow prevention
device is referred to as an “open” water
system.
As water is heated, it expands in volume and
creates an increase in the pressure within the
water system. This action is referred to as
“thermal expansion”. In an “open” water
system, expanding water which exceeds the
capacity of the water heater flows back into
the city main where the pressure is easily
dissipated.
A “closed water system”, however, prevents
the expanding water from flowing back
into the main supply line, and the result of
“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!
The suggested method of controlling thermal
expansion is to install an expansion tank in
the cold water line between the water heater
and the check valve (refer to the illustration
on the next page). 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 valve. Other methods of controlling
thermal expansion are also available. Contact
your installing contractor, water supplier or
plumbing inspector for additional information
regarding this subject.
Water Supply Connections
Refer to the illustration on the next page
for suggested typical installation. The
installation of flexible connectors is
recommended on the hot and cold water
connections. Flexible connections provide
vibration isolation and allow the water heater
to be easily disconnected for servicing if
necessary. The HOT and COLD water
connections are clearly marked and are
3/4in. NPT on all models. Install a shut-off
valve in the cold water line near the water
heater.
See page 8 on "To Fill The Water Heater".
NOTICE: DO NOT apply heat to the
HOT or COLD water connections. If sweat
connections are used, sweat tubing to
adapter before fitting adapter to the water
connections on heater. Any heat applied to
the water supply fittings will permanently
damage the dip tube and/or heat traps.
Condensate Drains
Consult local codes or ordinances for
specific requirements. Refer to page 7.
•
IMPORTANT: When making drain fitting
connections to the drain tubing, use a thin
layer of piping tape or silicone and install
hand tight.
All drain lines must be pitched
downward away from the unit a
minimum of 1/8" per foot of line to
ensure proper drainage.
•
Drain lines must include a P-trap if
connected to a sewer pipe.
IMPORTANT: When making drain fitting
connections to the drain tubing, DO NOT
overtighten. Overtightening fittings can split
pipe connections on the drain pan.
•
If no drain is available, then a common
condensate pump with a capacity no
less than 2 gallon per day must be
installed.
•
•
DO NOT allow condensate to drain into
the water heater drain pan.
•
The drain line should be insulated
where necessary to prevent sweating
and damage due to condensate forming
on the outside surface of the line.
•

in the opening provided and marked for the purpose on the water heater. No valve of any type
should be installed between the relief valve and the tank.
Relief Valve
! WARNING: The
pressure rating of
the relief valve
must not exceed
150 PSI, the
maximum working
pressure of the
water heater as
marked on the
rating plate.
The btu/h 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 the front of the heater
(1 watt=3.412 btu/h).
Connect the outlet of the relief valve
to a suitable open drain so that the
discharge water cannot contact live
electrical parts or persons 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 of the valve and must
pitch downward from the valve to allow
complete drainage (by gravity) of the
relief valve and discharge line. The
end of the discharge line should not be
threaded or concealed and should be
protected from freezing. No valve of
any type, restriction or reducer coupling
should be installed in the discharge line.

! CAUTION: The presence of water
in the piping and water heater does
not provide sufficient conduction for a
ground. Non-metallic piping, dielectric
unions, flexible connectors etc. can
cause the water heater to be electrically
isolated.
Insulation Blankets
Insulation blankets, available to the
general public, for external use on electric
water heaters are not necessary. The
purpose of an insulation blanket is to
reduce the standby heat loss encountered
with storage tank heaters. This water
heater meets or exceeds the National
Appliance Energy Conservation Act
standards with respect to insulation and
standby loss requirements making an
insulation blanket unnecessary.
! CAUTION: If local codes require the
application of an external insulation
blanket to this water heater, pay careful
attention to the following so as not to
restrict the proper function and
operation of the water heater:
The manufacturer’s warranty does not
cover any damage or defect caused by
installation, attachment or use of
any type of energy saving or other

Ducting Requirements
Always check with local building and
HVAC codes before designing the duct
system
The water heater may be ducted to the
outdoors or another space as described in
these instructions. Ducting configurations
that does not comply with these
guidelines are not supported.
DO NOT connect this water heater to
existing duct work; it must be ducted
separately from other appliances.
Ducting approved for HVAC applications
is required.
Ducting must be adequately supported
along both vertical and horizontal
lengths.
UL Certified terminations must be
used for ducting to the outside. These
terminations have been evaluated to
ensure there is sufficient protection
from rain water entry and resistance to
air flow is minimized.
Indoor registers approved for HVAC
applications is required.
Rigid ducting must be isolated from
floor joists or other structural members
to minimize the transmission of noise
and vibration. A short section (12
inch minimum) of flexible duct must
be used between the water heater and
rigid ducting as an isolation method.
Every foot of flexible ducting counts as
three feet of rigid ducting.
Ducting must be insulated per HVAC
codes (to prevent condensation).
Ensure cold air exhaust is sufficiently
away from structures to prevent
condensation on surfaces.
Maximum heater performance is
obtained by lowering the resistance to
air flow (regular filter maintenance is
beneficial) and providing the unit with
warm moist air.
Considerations when planning the duct
system:
 Run the ducting the most direct
route possible.
 Limit the number of elbows/bends.
 Use the largest duct size possible.
 Use the largest termination possible.
 Consider placement and direction of
terminations (reduce recirculation of
exhaust into the intake).
Calculated length of duct is the
length on the inlet plus the length
on the outlet. Any combination of
duct lengths on the inlet and outlet is
supported up to the maximum duct
length (Table 1).
Duct System Configuration
The inlet and outlet ducting
connections on the water heater
accepts 8 inch diameter ducting. No
additional adaptors are needed.
7 inch, 6 inch, 5 inch diameter
ducting is supported. Table 1 lists the
total feet of ducting allowed. For
duct diameters smaller than 8 inch
diameter, Table 1 takes into account
the duct reducer(s) and up to 10 feet
of 8 inch rigid ducting (two elbows)
before the duct reducer(s) at the unit.
Duct Reducers must be installed
within 10 feet (two elbows) of the unit
or within 2 feet of the end of the duct.

Elbows/Bends
Rigid duct elbows and flex bends
greater than 45° is considered an elbow.
Flexible ducting bends’ inner radius
cannot be less than its diameter. If
bends with tighter radiuses are needed,
a rigid elbow must be used.
Maximum number of elbows/bends
allowed are shown in [brackets] in
Table 2.
Terminations/Registers
Table 2 equivalent feet for terminations
includes the rodent screen.
For terminations and registers with
smaller diameters than the duct
diameter, Table 2 accounts for the duct
reducer and termination/register. Smaller
diameter terminations and registers
with more than a 2 ft. connection is not
supported.
Damper
If ducting to the outside using an
exhaust duct only (no intake duct), an
approved Rheem damper should be
installed no further than 10 ft. of rigid
ducting total (two elbows equivalent)
from the unit. This prevents outside
air from coming into the living space.
If ducting air from the outside to
the inlet of the heater, no provision
is made to prevent outside air from
flowing into the living space.

NOTICE: These
seven questions
should be answered
to ensure correct duct
configuration.
See Ducting Example.
Ducting to outside of building or another room? Outside building.
Length of duct from water heater to termination? 20 ft.
Flexible or Rigid ducting? Flexible.
Diameter of ducting used? 8 in. Diameter
Diameter of wall penetrations? 5 in. Diameter
Number of elbows/bends? 3 Total – One on inlet and Two on Outlet
I. Does calculated ducting length exceed maximum allowable table?
a. 20 ft. (Outlet duct length)
b. 10 ft. (1 rigid elbow and 1 bend on outlet)
c. 20 ft. (reduced diameter termination outlet)
d. 20 ft. (Inlet duct length)
e. 5 ft. (1 Bend on inlet)
f. 20 ft. (reduced diameter termination inlet)
g. Total = 20+10+20+20+5+20 = 95 ft.
Using flexible 8 in. diameter duct, the maximum duct length allowed is 125
ft.; therefore, because 95 ft. is less than 125 ft., this is an acceptable ducting
configuration.
Accesory Kits SP20887 (2 Kits), SP20889 (2 Kits) and SP20890 (1 Kit) should
be purchased for this installation.

Operating the water heater
CAUTION: 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 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 appliance connected to the hot water system. If hydrogen is
present, there will be an unusual sound such as air escaping through the pipe as the water begins to flow. DO NOT
smoke or use an open flame near the faucet at the time it is open.

If
understanding or following the
Operating Instructions or the
Care and Cleaning section, it is
recommended that a qualified
person or serviceman perform the
work.
Safety Controls
The water heater is equipped with a
temperature limiting control (ECO)
that is located above the upper heating
element in contact with the tank
surface. If for any reason the water
temperature becomes excessively
high, the temperature limiting control
(ECO) breaks the power circuit to
the heating element. Once the control
opens, it must be reset manually.
CAUTION: The cause of the high
temperature condition must be
investigated by qualified service
technician and corrective action
must be taken before placing the
water heater in service again.
To reset the temperature limiting
control: (Refer to Illustration in Cavity
Insert section):
Disconnect all power to unit
before starting maintenance.
Remove the upper cavity cover
and insulation.
Press the red RESET button.
Replace the insulation, jacket
access panel and plastic housing
before turning on the power to
the water heater. Water Temperature Setting
! DANGER: There is a
hot water scald potential if
the thermostat is set too
high. Households with small
children, disabled, or
elderly persons may require
a 120°F or lower thermostat
setting to prevent contact
with HOT water.
The temperature of the water in the
water heater can be regulated by
selecting the desired temperature on
control display.
Safety and energy conservation
are factors to be considered when
selecting the water temperature setting
of the water heater. The lower the
temperature setting, the greater the
savings in energy and operating costs.
To comply with safety regulations the
temperature is factory set at 120°F or
less where local codes require. This is
the recommended starting point.
Water temperatures above 125°F can
cause severe burns or death from
scalding. Be sure to read and follow
the warnings outlined in this manual
and on the label on the water heater.
This label is located on the front of the
water heater.
Mixing valves are recommended
for reducing point of use water
temperature by mixing hot and cold
water in branch water lines. It is
recommended that a mixing valve
complying with the Standard for
Temperature Actuated Mixing Valves
for Hot Water Distribution Systems,
ASSE 1017 be installed. See page 4
for more details and contact a licensed
plumber or the local plumbing
authority for further information.
The chart on the page 3 may be used
as a guide in determining the proper
water temperature for your home.

Care and cleaning of the water heater
Draining the Water Heater
CAUTION: Shut off power to the
water heater before draining water.
DANGER: Before manually
operating the relief valve, make
certain no one will be exposed to the
hot water released by the valve. The
water drained from the tank may be
hot enough to present a scald
hazard and should be directed to a
suitable drain to prevent injury or
damage.
In order to drain the water heater, turn
off the cold water supply. 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 the water heater and direct
the stream of water to a drain. Open
the valve.
Routine Preventative Maintenance
Properly maintained, your water heater
will provide years of dependable
trouble-free service.
It is suggested that a routine
preventive maintenance program be
established and followed by the user.
DANGER: Before
manually operating the
relief valve, make certain
no one will be exposed to
the danger of coming in
contact with the hot water
released by the valve. The
water may be hot enough to
create a scald hazard. The
water should be released
into a suitable drain to
prevent injury or property
damage.
NOTICE: 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 water
supplier or your plumbing
contractor on how to
correct this. DO NOT plug
the relief valve outlet.
Most electrical appliances, even
when new, make some sound when
in operation. If the hissing or singing
sound level increases excessively,
Contact a qualified installer or
plumbing contractor to inspect.
IMPORTANT: See "DANGER
on left". At least once a year, lift
and release the lever handle on the
temperature pressure relief valve,
located on the side of the water heater,
to make certain the valve operates
freely. Allow several gallons to flush
through the discharge line to an open
drain.
It is recommended to clean the
filter on top of the heat pump
when "Clean filter reminder" alert
appears. Clean by washing with
mild detergent and water. Dry and
replace. Remove the filter by lifting
up, then replace by lowering back
into the filter slot on top of the unit.
See Figure below.
to ensure they are open to permit
draining of the condensate.
A water heater’s tank can act as a
setting basin for solids suspended
in the water. 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
be drained from the water heater’s tank
every month to clean the tank of these
deposits.
Rapid closing of faucets or solenoid
valves in automatic water using
appliances can cause a banging noise
heard in a water pipe. Strategically
located risers in the water pipe system
or water hammer arresting devices can
be used to minimize the problem.

Care and Cleaning of the Water Heater
Vacation and Extended Shut-Down
NOTICE: Refer to the
Hydrogen Gas Caution in
the Operating Instructions.
If the water heater is to remain idle for
an extended period of time, the power
and water to the appliance should
be turned off to conserve energy
and prevent a build-up of dangerous
hydrogen gas.
After a long shut-down period, the
water heater’s operation and controls
should be checked by qualified service
personnel. Make certain the water
heater is completely filled again before
placing it in operation.
The water heater and piping should be
drained if they might be subjected to
freezing temperatures.
Anode Rod
NOTICE: DO NOT remove
the anode rod from the
water heater’s tank.
Operation with the anode
rod removed will greatly
shorten the life of the glass
lined tank and will exclude
warranty coverage.
22
This water heater is equipped with
an anode rod designed to prolong
the life of the glass-lined tank. The
anode rod is slowly consumed, thereby
eliminating or minimizing corrosion of
the glass-lined tank.
Water sometimes contains a high
sulfate and/or mineral content and
together with cathodic protection
process can produce a hydrogen
sulfide, or rotten egg odor in the
heated water. Chlorination of the water
supply should minimize the problem.
