C. Water Chemistry Requirements

Chemical imbalance of the water supply may aect eciency and
cause severe damage to the appliance and associated equipment.
Water quality must be professionally analyzed to determine
whether it is necessary to treat the water. Various solutions are
available to adjust water quality. Adverse water quality will aect
the reliability of the system. In addition, operating temperatures
above 135oF will accelerate the build-up of lime scale and possibly
shorten appliance service life. Failure of an appliance due to
lime scale build-up, low pH, or other chemical imbalance IS NOT
covered by the warranty.

The water must be potable, free of corrosive chemicals, sand,
dirt, and other contaminates. It is up to the installer to ensure the
water does not contain corrosive chemicals or elements that can
damage the heat exchanger. Potable water is dened as drinkable
water supplied from utility or well water in compliance with EPA
secondary maximum contaminant levels (40 CFR Part 143.3). If
the water contains contaminants higher than outlined by the EPA,
water treatment is recommended and additional, more frequent
maintenance may be required.

If you suspect that your water is contaminated in any way,
discontinue use of the appliance and contact an authorized
technician or licensed professional.

• Water pH between 6.5 and 8.5

• pH levels below 6.5 can cause an increase in the rate of
corrosion. pH of 8.5 or higher can potentially cause lime
scale build-up

• Maintain water pH between 6.5 and 8.5. Check with litmus
paper or have it chemically analyzed by a local water
treatment company.

• If the pH is not between 6.5 and 8.5, consult a local water
treatment company for solutions.

• Hardness less than 12 grains (200 mg/L) (Residential Use ­water temperatures below 140oF)

• Hardness levels above the required amounts can lead to lime

scale build-up throughout the system. Water below 5 grains/
gallon (85 mg/L) may be over softened.

• Consult local water treatment companies for unusually

hard water areas (above the required amounts) or for other
treatment solutions if water is being over softened (below 5
grains/gallon [85 mg/L]).

• Chloride concentration less than 100 ppm (mg/L)

• Do not ll appliance or operate with water containing

chlorides in excess of 100 ppm (mg/L).

• Using chlorinated fresh water should be acceptable as levels

are typically less than 5 ppm (mg/L).

• Do not connect the appliance to directly heat swimming

pool or spa water.

• Total Dissolved Solids (TDS) less than 500 ppm (mg/L)

• Total dissolved solids are minerals, salts, metals, and charged

particles that are dissolved in water.

• The greater the amounts of TDS present, the higher the

corrosion potential due to increased conductivity in the
water.

• If using softened water to ll the appliance, it is still possible

to have high TDS. This water can be corrosive. Consult local
water treatment companies for other treatment solutions to
reduce this aect.

*NOTE: To promote appliance service life, it is strongly recommended
to follow the maintenance procedures in this manual.

Failure of electric elements due to lime scale build-up on the heating
surface, low pH, or other imbalance IS NOT covered by the warranty.

Part 3 - Piping

A. Plumbing

It is mandatory that all plumbing be done in accordance with federal,
local, and state plumbing codes and practices. Failure to properly
install the water heater WILL VOID the warranty. It is also necessary to
use both thread tape and pipe sealing compound on all mechanical
plumbing connections.
It is recommended to use unions on the hot and cold water connections
to easily disconnect the water heater for servicing.

the cold water inlet line. Contact your installing contractor, water
supplier, or plumbing inspector for additional information regarding
thermal expansion.

C. Condensation

Condensation can form on the water heater when it is rst lled with
water, and may also occur with a heavy water draw and very cold inlet
water temperature. This condition is not unusual and will disappear
as the water becomes heated. However, if the condensation should
continue, examine the piping and ttings for possible leaks.

D. Insulation Blankets

Dielectric unions or galvanized steel ttings must not be used in a
system with this water heater. Doing so WILL VOID the warranty. It
is recommended to use only copper, brass, or stainless steel ttings.
Teon thread sealant and pipe sealing compound must be used on
all connections.

1. Install a shut-o or check valve or both on the inlet connection on
the top of the heater. Connect the cold water supply line to the shut­o valve or check valve. Refer to piping Applications, this manual.

Do not apply heat to the Hot or Cold water heater connections. If
sweat connections are used, sweat tubing to the adapter before
tting adapter to the water connections on the heater. Any heat
applied to the water heater connections will permanently damage
the dip tube and/or heat traps. Damages due to improper installation
practices ARE NOT covered by warranty.

2. Connect the hot water line to the connection marked “HOT” on the
top of the water heater.

3. Install the T&P Valve in the opening provided near the top of the
heater.

4. Install drain valve in the opening provided near the bottom of the
heater.

B. Thermal Expansion

A check valve may be installed in the cold water inlet line as a separate
backow preventer, or may be part of a pressure reducing valve, water
meter, or water softener. An “open water system” refers to a system
without a check valve. A “closed water system” refers to a system with
a check valve installed in the cold water inlet line.
As water is heated, it expands in volume and increases 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 system ows back into the city main where pressure is easily
dissipated.
A closed water system prevents expanding water from owing back
to the city main. The resulting thermal expansion can rapidly increase
pressure in the water heater and system piping. This rapid pressure
increase can exceed the setting of the pressure relief valve, causing it to
operate during each heating cycle, resulting in discharge from the T&P.
This rapid and repeated expansion and contraction of components
in the system can cause premature failure of system components,
including the relief valve and possibly the water heater. Replacing the
relief valve will not correct thermal expansion.
A potable hot water expansion tank is required to oset thermal
expansion. Expansion tanks are designed with an air cushion built
in that compresses as system pressure increases, thereby relieving
the overpressure condition and eliminating repeated operation of
the relief valve. This expansion tank should be installed in the cold
water line between the water heater and check valve, and must be
sized for the entire water volume of the hot water system. See piping
Applications.
Other methods of controlling thermal expansion are available. Check

with the local water utility to determine if a check valve exists in

If local codes require external application of insulation blanket
kits, the manufacturer’s instructions included with the kit must be
carefully followed.
In addition, pay careful attention to the following so as not to
restrict the proper function and operation of the water heater:

• Do not cover the operating or warning labels attached to
the water heater or attempt to locate them on the exterior
of the insulation blanket.

• Do not apply insulation to the top of the water heater. This
could interfere with the safe operation of the electrical
junction box.

• Do not cover the jacket access panel(s) to the thermostat
and heating elements or T&P valve.

• Inspect the insulation blanket frequently.

Failure to follow these instructions could result in property
damage, severe personal injury, or death.

E. Temperature and Pressure Relief Valve

For protection against excessive pressures and temperatures in this
water heater, install temperature and pressure protective equipment
as required by local codes, but not less than a combination T&P
valve meeting the requirements for Relief Valves and Automatic Gas

Shuto Devices for Hot Water Supply Systems, ANSI Z21.22B / CSA 4.4­M99 by a nationally recognized testing laboratory that maintains

periodic inspection of production listed equipment and materials.
This valve must be marked with a maximum set pressure not to
exceed the marked maximum working pressure of the water heater.
Install the T&P valve into the opening provided and marked for this
purpose on the water heater. The T&P valve must be plumbed down
so discharge can exit at least 6” above the structural oor. The relief
line cannot be in contact with any live electrical parts.

lp-608 Rev. 000 Rel. 001 Date 3.15.18

To avoid water damage or scalding due to relief valve operation:

• Discharge line must be connected to relief valve outlet and
run to a safe place of disposal. Terminate the discharge line
in a manner that will prevent possibility of severe burns or
property damage should the relief valve discharge.

• Discharge line must be as short as possible and the same
size as the valve discharge connection throughout its
entire length.

• Discharge line must pitch downward from the valve
and terminate at least 6” above the oor drain, making
discharge clearly visible.

• The discharge line shall terminate plain, not threaded, with
a material serviceable for temperatures of 375oF or greater.

• Do not pipe discharge to any location where freezing could
occur.

• No valve may be installed between the relief valve and
heater or in the discharge line. Do not plug or place any
obstruction in the discharge line.

• Test the operation of the relief valve after lling and
pressurizing the system by lifting the lever. Make sure the
valve discharges freely. If the valve fails to operate correctly,
immediately replace with a new properly rated relief valve.

• Test T&P valve at least once annually to ensure the
waterway is clear. If valve does not operate, turn the heater
“o” and call a plumber immediately.

• Take care whenever operating relief valve to avoid scalding
injury or property damage.

FAILURE TO COMPLY WITH THE ABOVE GUIDELINES COULD
RESULT IN FAILURE OF RELIEF VALVE OPERATION, RESULTING
IN POSSIBILITY OF SUBSTANTIAL PROPERTY DAMAGE, SEVERE
PERSONAL INJURY, OR DEATH.

RE-INSPECTION OF T&P RELIEF VALVES: T&P valves should
be inspected AT LEAST ONCE EVERY THREE YEARS, and
replaced if necessary, by a licensed plumbing contractor or

qualied service technician to ensure that the product has not
been aected by corrosive water conditions and to ensure that
the valve and discharge line have not been altered or tampered
with illegally. Certain naturally occuring conditions may corrode
the valve and its components over time, rendering the valve
inoperative. Such conditions can only be detected if the valve
and its components are physically removed and inspected. Do
not attempt to conduct an inspection on your own. Contact
your plumbing contractor for a re-inspection to assure continued
safety.

FAILURE TO RE-INSPECT THE T&P VALVE AS DIRECTED COULD
RESULT IN UNSAFE TEMPERATURE AND/OR PRESSURE BUILD­UP WHICH CAN RESULT IN PROPERTY DAMAGE, SERIOUS
PERSONAL INJURY, OR DEATH.

Do not thread a cap or plug into the relief valve or block relief
valve outlet line under any circumstances! Explosion and property
damage, serious injury, or death may result.

F. Scalding

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. Mixing valves can reduce but do
not eliminate the risk of scalding.
To avoid scalding:

• Set the water heater set point temperature as low as possible.

• Feel water before bathing or showering.

• If thermostatic valves are required, use devices specically

designed for such purpose. Install these devices in accordance

with instructions provided by the manufacturer.
Failure to install a temperature limiting or mixing valve and follow
these instructions could result in property damage, severe personal
injury, or death due to scalds.

This water heater can
deliver scalding water. Be
careful whenever using
hot water to avoid scalding
injury. Certain appliances
such as dishwashers and
automatic clothes washers
may require increased
water temperatures. By
setting the thermostat
on this heater to obtain
the increased water
temperature required by
these appliances you may
create the potential for
scald injury.

To protect against injury,
install a mixing valve in the
water system. This valve
will reduce point of use
discharge temperatures by
mixing cold and hot water
in branch supply lines.
Such valves are available
from your local plumbing
supplier.

Table 1 details the relationship of water temperature and time with
regard to scald injury and may be used as a guide in determining the
safest water temperature for your applications.

G. Filling the Heater

• Make certain that the drain valve is completely closed.

• Open the shut-o valve in the cold water supply line.

• Open the hot water faucets to allow air to vent from the heater

heater. Failure to follow this warning will result in premature product
failure and VOID the warranty.

Step #3 - Remove the element with a 1 1/2” socket wrench or element
tool.
Step #4 - Inspect the removed element. Determine whether the
replacement element will need a square or circular gasket and washer.

Failure to rell the tank before restoring power to the water
heater will result in damage to the heating elements and property
damage. Such damages ARE NOT covered by warranty.

Part 7 - Maintenance

Considerations

• To avoid electric shock, disconnect electrical supply before
performing maintenance.

• To avoid severe burns, allow heater to cool before performing
maintenance.

NOTE: In addition to the routine maintenance detailed in this manual,
this water heater should be inspected annually by a qualied service
technician to assure that all the equipment is operating safely and
eciently. The owner should make necessary arrangements with a
qualied heating contractor for periodic maintenance of the heater.
The qualied installer / service technician must also inform the owner
that lack of proper care and maintenance may result in a hazardous
condition, premature heater failure, and void the warranty.
Routine preventative maintenance ensure the water heater operates
safely and eciently over its service life. The Owner / User may
perform the maintenance activities described below.

Monthly (Every two weeks in hard water locations)

It is recommended that a few quarts of water be drained from the
heater. This will ush sediment deposits from the bottom of the
heater and lengthen the heater’s service life. Turn o power to
the heater during ushing operation, so the elements will not be
damaged.

Figure 9 - Heating Element Detail

Step #5 - Ensure thread and opening are completely free of debris. Use

a nylon brush to clear away any debris.
Step #6 - Put a small amount of NSF approved lubricant and sealant
on the appropriate gasket and/or washer for the installation. Put the
gasket and/or washer on the element.
Step #7 - Screw the element clockwise into the tank, and tighten with
the 1 1/2” socket wrench or element tool. Use the appropriate gasket
for the water heater (two are included in the kit), and ensure the gasket
seats properly.

NOTE: Repeat Steps 3 - 6 as Necessary for Multiple Elements

Step #8 - Open the main cold water inlet. If the water heater has been

isolated from the system, open the valves. Rell the tank with cold
water. Open a hot water faucet high in the system to bleed any air
pressure from the system. Water will ow freely when air is completely
bled.

lp-608 Rev. 000 Rel. 001 Date 3.15.18

Failure to shut o the heater when draining may damage the
heating elements. Operating a partially lled / empty water
heater could lead to damage from “dry-ring”. Failures due to such
damage ARE NOT covered by warranty.

Water drained from the water heater may be scalding hot. Take
care to avoid scalding. Wear gloves and safety glasses, and direct
water to a safe drainage location. It is recommended to turn
power o to the water heater and run water at a hot water faucet
until it cools BEFORE draining water from the heater. Failure to
comply with this warning could result in property damage, severe
personal injury, or death.

To ush the tank, attach a hose to the eld installed drain valve.
Close the cold water supply line shut-o valve. Open the drain valve
and hot water faucet(s) to vent heater while draining. Direct the ow
of water to a drain or bucket where it will not cause damage.
Flush until water runs clear to complete this operation. Close drain
valve and reopen the supply line shut-o valve. Close the hot water
faucet(s) once all air has been bled from the system (when water
runs freely). Make certain that the heater is completely full of water
before restoring power.

Periodically (At least twice a year)

Check around the water heater and related plumbing for leaks. If
the combination temperature and pressure relief valve discharges
periodically, or water is leaking from around the heating elements,
there may be a problem with your water system. DO NOT ATTEMPT
TO REPAIR LEAKS YOURSELF! Contact a qualied service contractor
for assistance.
Check the area around the water heater for ammable liquids or
combustible materials. If any are found, remove from the area.

Vacation (Extended shut-o periods)

During extended mild or warm weather periods when hot water will
not be in use, shut o the electric power to the tank. When hot water
is needed again, restore power to the water heater.
During extended cold weather periods when hot water will not be
in use and prone to freezing conditions, shut o electric power to
the tank, close the supply line shut-o valve, open the drain valve
and drain the water heater to a safe drainage location (as detailed
previously). Once drained, close the drain valve. When hot water is
needed again, restore the water supply to the tank. Once the tank is
full, restore power.

Water drained from the water heater may be scalding hot. Take
care to avoid scalding. Wear gloves and safety glasses, and direct
water to a safe drainage location. It is recommended to turn
power o to the water heater and run water at a hot water faucet
until it cools BEFORE draining water from the heater. Failure to
comply with this warning could result in property damage, severe
personal injury, or death.

The maintenance activities described below are only to be
performed by the Installer / Qualied Service Provider. These
maintenance items should be performed during recommended
annual service and any service calls.

1. Ask the owner / user if there have been any issues with the water
heater. Diagnose any heater issues and repair / replace parts as
necessary.

2. Check the water heater and related plumbing for leaks. Repair any
that are found.

3. Check the area around the water heater for ammable liquids or
combustible materials. If any are found, remove from the area.

4. Check the heating elements while the heater is in operation. If
the elements are hissing / singing excessively, they may need to be
cleaned. Inspect the elements and clean if necessary.

5. Inspect the Temperature and Pressure (T&P) Relief Valve. See
instructions below.

6. Turn power supply o to the water heater. Open the drain valve
and drain a few gallons of water from the tank to clear any hard
water deposits. Once complete, close the drain valve and restore
power to the water heater.

T&P Relief Valve Maintenance Instructions:

• Annually: Certain naturally occuring mineral deposits may
adhere to the valve, blocking waterways and rendering the
valve inoperative. The T&P Relief Valve lever must be operated
to ensure the waterways are clear. If waterways are clear, hot
water will discharge from the valve. Take precautions to avoid
personal injury and property damage from contact with hot
water. Before operating lever, check to see that a discharge
line is connected to the valve, directing the ow of hot water
from the valve to a proper place of disposal.

• Replacement of the valve is required if no water ows when
the lever is operated. Turn the water heater o until the valve
is replaced.

• If water ows from the valve, drain a few gallons from the tank
to ensure the water ows freely.

• At least once every three years: To ensure that the T&P
valve has not been aected by corrosive water conditions
and that the valve and discharge line have not been altered
or tampered with illegally, relief valves should be inspected,
and replaced, if necessary, by a licensed plumbing contractor
or qualied service technician.

Failure to comply with these guidelines could result in failure
of relief valve operation, and possibly result in substantial
property damage, severe personal injury, or death.
