1.2 BUFFER TANK
The ECO ULTRA boiler optimizes runtimes and
limits on/off cycling of the energy source(s).
When the minimum system load is lower than the
energy source’s minimum capacity, the system
will generate short cycles. This causes premature
wear of the equipment and substantially
decreases the system’s energy efficiency.
1.3 STORAGE TANK
Any hydronic heating system with the ECO
ULTRA stores energy like a battery. When a
demand is made for limited heating (for example,
when there is little difference between indoor and
outdoor temperatures) or when it is used with a
low-capacity energy source, the energy required
will first come from the tank’s thermal storage.
In addition, for this mode, it is recommended to
adjust the setpoint of the renewable energy
source to a value greater than 10°F to 20°F than
the ECO ULTRA to reduce the start-up of the
electrical elements.
1.5.2 Automatic transfer mode
The boiler can also be operated in the automatic
transfer mode, where the ECO ULTRA electric
boiler turns on the distribution pump, reads the
water temperature and activates the electrical
elements if authorized by an external signal. The
elements are then switched on according to the
adjustment parameters of the UltraSmart
controller.
1.4 HYDRAULIC SEPARATOR
Adding an ECO ULTRA boiler to a hydronic
heating system helps to evacuate air, eliminates
impurities, and ensures the optimal functioning of
the pumps—not only for the energy source but
also for the distribution system.
1.5 BACK UP BOILER
The addition of an ECO ULTRA electric boiler to
a hydronic heating system acts as a back-up
source to the main renewable energy system.
The boiler can operate in two modes:
autonomous electrical mode or automatic
transfer mode.
For both modes, it is recommended to use the
outdoor sensor supplied with the equipment. The
outdoor sensor allows the boiler water
temperature to be modulated according to the
outside temperature. It also makes it possible to
stop the heating of the electric elements when the
outside temperature exceeds a certain
temperature. The use of these functions makes it
possible to optimize the start-up of the main
renewable energy system.
1.5.1 Autonomous electrical mode
By default, the boiler operates in autonomous
electrical mode where, on request of heat, the
ECO ULTRA boiler turns on the distribution
pump, reads the water temperature and activates
the electrical elements according to the
Parameters of the UltraSmart controller
independently if the main renewable energy
source is on or off.

3.6 SYSTEM SETUP
Figures 2 to 8 indentify and show location of the
different components. They also provide typical
heating system installation. External components
location may vary in order to accommodate
specific installation and local codes and
regulation.
3.6.1 Connecting the boiler
The boiler heating supply and return connections
are located on the left or right side and are 1”
NPTM for Model 50 and 1-¼’’ NPTM for model
70. The connections at the left or right can be
used. The important thing is that the fluid
circulation must be made from the bottom to the
top (see figure 1)
Unions are recommended on the inlet and outlet
pipes to disconnect the water heater easily for
servicing if necessary.
Dielectric (insulating) unions should be used if
copper-steel connections are made.
Insulate all pipes containing hot water, especially
in unheated areas.
3.6.2 Flow-check valve
pressure is affected by the type of heating system
and the size of the expansion tank installed.
The expansion tank is used to absorb the
increase of water volume from the boiler and the
system when it is working.
The model selection should be based on the
maximum working temperature and the water
volume of the total system. For example, a
system with radiators contains much more water
volume than a baseboards system. Likewise, the
ECO ULTRA also contains an important volume
of water that has to be added :
ECO ULTRA 50 : 48 usgal
ECO ULTRA 70 : 71 usgal
With this information, the installator or distributor
should be able to make an appropriate selection
for an expansion tank.
Here are some minimal recommendations for
different types of heating systems.

If the heating system uses a single or multiple
circulators without motorized zone valves, a flowcheck valve must be installed to avoid all
possibility of gravity flow and heat loss during
non-draw periods. Modern circulators are
typically provided with spring loaded check valves
that will provide adequate protection.
If the heating system uses motorized zone
valves, these will provide adequate protection.
The expansion tank is generally installed on the
wall or ceiling. It also has to be well supported.
3.6.3 Pressure relief valve
3.6.5 Water pressure regulator
The boiler is delivered with a factory installed tank
pressure relief valve set at 207 kPa (30 psi).
NEVER replace the pressure relief valve by a
higher set pressure one.
Connect the outlet of the relief valve downward
toward a safe location.
Relief valve outlet pipe diameter must not be of
smaller diameter than the relief valve outlet. The
oulet pipe end must be visible in order to observe
any relief incident and be protected from freezing.
NEVER cap or plug a pressure relief valve
outlet. The pressure relief valve is a safety
apparatus and preventing its proper operation
may cause death, injury or property damage.
3.6.4 Expansion tank
When operating the ECO ULTRA and the heating
system, pressure will vary between 83 kPa and
193 kPa (12 psi to 28 psi). The operating
The boiler should be installed in such a way that
it can automatically be fed with water in the event
of a pressure drop.
The minimum pressure obtained when the
system is cold is generally 12 psi (83 kPa).
This accessory shall be equipped with one or
more check valves to avoid all possibilities of the
boiler water returning to the potable water supply
network (local regulation should be applied)
3.6.6 Automatic Air Vent
The ECO ULTRA has a factory installed tank
automatic air vent. This air vent function is to vent
any air present in the tank.
For proper operation, do not cap or block the air
bleeder outlet.
For proper operation of the heating system, it may
be necessary to add air bleeders to the heating
system circuits.
ECO ULTRA Electric Boiler Installation, Use and Care Manual
(Revision June 2017),
Page 12.
3.6.7 Heating pump
3.7.3 Outdoor temperature sensor
A circulating pump (not included) is required for
the heating system to deliver heating fluid to the
different heating zones. Sizing of the pump is
base on the heating system configuration and is
done by the installator (heating technician,
plumber).
If you want the boiler target temperature to
modulate according to the outdoor temperature
(when the outdoor temp. will get colder, the target
temperature will get higher). The supplied
outdoor sensor will have to be connected to S1
S1 before turning the power on to the unit.
The installation of this sensor cancels the
operation of the boiler when the outdoor
temperature exceeds the selected value
corresponding to the maximum temperature
required for heating.
3.7 BOILER WIRING:
3.7.1 Main power supply
The electrical wiring and grounding must conform
to local codes or, in their absence, to the National
Electrical Code. Local codes have authority for
wiring and electric breaker sizing. It is the
electrical technician responsibility to insure that
the installation meets the applicable codes
requirements.
On installation where a 120 Vac power is required
for a heating pump and other outboard
components, main power supply to the ECO
ULTRA must be a 120/240 Vac, single phase, 60
Hz using 3 conductors (L1 – L2 – N) and a ground
wire.
On installation where no 120 volts external
components need to be powered by the ECO
ULTRA, Power supply could then be supplied
with only two conductors L1-L2 with a ground
wire.
Electrical current draw for the boiler being
installed is indicated on the boiler’s name plate.
The electrical technician needs this information in
order to determine the proper electrical breaker
and cable. The cable can be either aluminum or
copper, but must be adequate for 75°C operation.
If aluminum cables are used, it shall be of an
adequate size (generally bigger) and particular
consideration will have to be respected such as
the use of DE-OX inhibitors in order to meet the
National electrical code.
3.7.2 Heating pump wiring
If the building heating system is designed for a
single pump operation and the electrical power to
the boiler is 120/240 Vac 3 conductors and
ground type, the pump (1/6 HP max) can be
directly connected to the boiler electric panel “PP”
terminals. The boiler control will operate the
pump as soon as a heat demand is signalled by
the space thermostat.
This control strategy optimize the use of the main
renewable energy source by reducing the use of
electric elements of the ECO ULTRA boiler.
1. Sensor location:
-Outside the building at a location which best
represents the heat demand of the building (a
wall facing north for most of the buildings and on
a south one on buildings with large windows
facing south).
-It should not be exposed to external heat
sources (dryer outlet, window openings,
uninsulated walls).
-It should not be installed in a location where it
could be covered with snow.
2. Installation:
-Drill a 9/64” dia. hole through the wall and insert
the sensor cable.
-Fix the sensor cover to the wall using supplied
screw.
-With an electric cable (100ft max.) having 2
conductors 20ga. connect one end of this cable
to the sensor cable using twist-on wire
connectors and the other end to terminals S1 &
S1 of the boiler.
If you wish to operate the boiler at a fixed target
temperature, simply do not connect the sensor
before applying the power to the unit (do not put
a jumper between S1&S1 if the outdoor sensor is
not used).
3.7.4 Room thermostat wiring
3.7.4.1 Single heating zone
Using a two (2) wires central thermostat, connect
the low-voltage thermostat dry contact to the W
and R terminals on the ECO ULTRA electrical
panel.
Using a three (3) wires central thermostat,
connect the C, W and R terminals to the boiler
electric panel corresponding terminals.
ECO ULTRA Electric Boiler Installation, Use and Care Manual
(Revision June 2017),
Page 13.
DO NOT apply external current to these
terminals.
3.7.4.2 Zone valve zoning
Connect the low-voltage thermostat to the zone
valve motor. The components must wired such
that, upon a heating demand from a thermostat,
only the corresponding zone valve will be
actuated and will in turn activate the ECO
ULTRA. Connect the zone valve dry end switch
contact to the W and R boiler electrical panel
terminals
ECO ULTRA
The 24 Vac power supply transformer used
must be powerful enough to supply
simultaneously all zone valves.
3.7.5 Automatic transfer mode wiring
If needed, The ECO ULTRA boiler is designed to
automatically transfer the right energy source to
be in function. The automatic transfer mode is not
set by default. This mode allows to activate the
electric elements upon reception of an external
signal. The ECO ULTRA will select the
appropriate energy source and will activate the
renewable energy source or the electic boiler. If
the heating distribution system is equipped with a
single pump connected to the PP terminals of the
boiler, it will be activated on heat calls from the

4.1 INTRODUCTION
4.2 DISPLAYED INFORMATION
The ECO ULTRA boiler is mainly designed to be
installed on closed circuit applications where the
water of the heating system flows directly from
the boiler to the heating distribution system
(Standard parallel Piping system)
Two operation modes are then offered:
 Fixed boiler temperature set point (the
outdoor sensor shall not be installed)
Or
 Outdoor reset
The electronic control uses an LCD display to
make all adjustments and to visualize the
operation of the system.
Figure 11 : UltraSmart Controller Display

4.4 OPERATION IN “FIXED BOILER
TEMPERATURE SET POINT”
For installation where the boiler target
temperature shall be maintained at a fixed
temperature that will not vary in relation to the
outdoor temperature, the sequence of operation
will be as follow:
On a call for heat from the room thermostat, the
circulating pump will start and the boiler will
activate the number of stages required to get to
and maintain the outlet temperature of the boiler
near the selected target temperature. A rotation
of the stages based on an equal time period of
operation is provided.
N.B. The supplied outdoor temperature sensor
shall not be connected before applying the
electrical power to the unit
N.B. The supplied outdoor temperature sensor
must be connected before applying the electrical
power to the unit.
The boiler target temperature will be calculated
by the controller in relation to the parameters
selected
in
the
menu
and
the
maximum target temperature required when the
outdoor temperature will get to -10°F (-23°C). The
“STD” curve corresponds to the default maximum
temperature for a typical system and this value
can be modified from the “MIN” to “MAX” value
shown on the following tables.
4.5 OPERATION WITH “OUTDOOR
RESET”:
For installation where the boiler target
temperature shall modulate in relation to the
outdoor temperature; when the outdoor
temperature gets colder, the boiler target
temperature will increase.
On a call from the room thermostat, the
circulating pump will start and the boiler will
activate the number of stages required to get to
and maintain the outlet boiler temperature near
the target temperature established by the
controller according to the outdoor temperature.
A rotation of the stages based on an equal time
period of operation is provided.

4.6 PURGE DELAY OF THE PUMP
The controller offers the possibility to
stop the operation of the pump after an adjustable delay
once the heat demand has been completed.
The following choices are offered:
 “OFF” The pump will stop immediately when the
heat demand has been satisfied. This selection
shall be selected on systems equipped with
motorised fast closing zone valves in order to
prevent noise from water hammering.
 “15 sec to 60 min” delay where the pump will be
kept running to enable the pump to circulate
water into the system to equilibrate the heat in all
the building.
 “ON” The pump is in continuous operation.
Required on particular heating distribution
systems.
4.7 AUTOMATIC HEATING
SHUT DOWN
When the outdoor sensor is installed and the unit then
operates in the “outdoor reset” mode, the controller offers
the user the possibility to automatically stop the boiler
when the outdoor temperature reaches an adjustable
value (0°F (-17°C) à 105°F (40°C). This characteristic is
especially interesting on the following applications:
-Heating systems equipped with many thermostats
where the user wants to prevent the operation of the unit
if one of the thermostats has inadvertently been
activated.
-Heating systems where the owner supplies heat to a
lodger
-Systems connected to a geothermic or air-water
heat pump where we do not want the electric boiler
to be operating unless the outdoor temperature
drops to a selected degree.

4.8 CONFIGURATION OF THE CONTROLLER
Since each type of heating distribution system is
designed to operate at water temperatures that are
particular to its operation, the proper configuration of the
operating parameters of this particular system is
important to maximize its performance.
In order to do this, the installer will first have to tell the
controller if the application is in automatic transfer mode
or autonomous electric mode. The selection is made by
selecting the position “Elect.” for the autonomous electric
mode Or “Bi-Energ” for the automatic transfer mode on
the switch located at the back of the controller. This
selection will have to be made before applying voltage to
the unit. The default setting is the autonomous electric
mode “Elect.”
ECO ULTRA Electric Boiler Installation, Use and Care Manual
(Revision April 2017),
Page 20.
This being done, the installer will have to access the
configuration menu by pressing the
button for 2
sec. until the first menu appears. The selection of the
item or value is made by pressing the
button and by pressing the
button to get to the
next menu. See table 1 below to visualize the menu list
that will gradually be displayed.
If the buttons remain untouched for a period of 10 sec.,
the controller will register the value of the selection made
and return to the regular display position. It will also
return to the regular display after reviewing all the
operating parameters of the controller.
In case of a power failure, the parameters will be restored
as they were established before the failure.

Operation in “Boost” Option ON2 (only offered on
installation not operating in Dual-energy)
The controller incorporates a unique feature that enables
the target boiler temperature to automatically be
increased when the building heat load increases but
cannot be fulfilled with the actual boiler target
temperature and consequently the room thermostat(s)
cannot be satisfied within a pre-determined period.
Example:
-Return to normal heat load after low demand periods
occurring during sunny days.
The boost program is a marvellous feature that works
fine on applications where the number of room
thermostats is in limited quantity otherwise it may happen
that during very cold periods the heat demand from all
the thermostats may not become satisfied.
This option requires the installation of one or two stages
heating thermostats. The second stage of the
thermostat(s) will have to be connected to E1-E2 of the
boiler and the option ON2 selected.
Then the Boost mode will be instantaneously started

Installation
! WARNING
The manufacturer’s warranty does not cover
any damage or defect caused by installation
or attachment or use of any special
attachment other than those authorized by the
manufacturer into, onto, or in conjunction
with the water heater. The use of such
unauthorized devices may shorten the life of
the water heater and may endanger life and
property. The manufacturer disclaims any
responsibility for such loss or injury resulting
from the use of such unauthorized devices
Insulate all pipes containing hot water, especially
in unheated areas.
Cap or plug unused connections. If the water
heater is replacing a tankless coil in the boiler, do
not cap tube outlets in the tankless coil after
disconnecting from plumbing.
Thermometer(s) should be installed to indicate
the temperature of the water at or near the outlet
of the water heater and storage tank(s), if
provided.
DOMESTIC WATER CONNECTIONS
EXPANSION TANK FOR POTABLE
WATER
The Eco ULTRA boiler with optional heat
exchanger for DHW could be install in
autonomous electrical mode or automatic transfer
mode. Figures 20 and 21 show installation in
automatic transfer. According the supply
temperature of the renewable energy source the
DHW heat exchanger will heat or pre-heat the
domestic water. When supply temperatures are in
a range of 80oF to 130 oF un back-up water heater
need to be add.
Determine if there is a check valve, a back flow
preventer, a pressure-reducing valve, a water
meter or a water softener in the cold water supply
line.
The HOT WATER OUTLET and the COLD
WATER INLET connections are clearly marked.
Inlet water connections (COLD WATER INLET)
are to be made to the copper pipe (sweat
connection) at the bottom of the heater. Outlet
water connections (HOT WATER OUTLET) are
to be made to the copper pipe (sweat connection)
at the top of the heater.
The installation of copper unions or copper alloy
unions is recommended on the HOT and COLD
water lines, so that the water heater may be easily
disconnected for servicing if necessary.
Dielectric unions are required for protection of the
water heater if dissimilar pipe material like
galvanized pipe is used.
Install shutoff
convenience.
(ball)
valves
for
servicing
A check valve creates a closed system and
prevents the water, as it is being heated, from
expanding back into the cold water supply line.
Pressure can build up within the water heater,
causing the relief valve to operate during a
heating cycle. This excessive operation can
cause premature failure of the relief valve and
possibly of the water heater itself.
Replacing the relief valve will not correct the
problem. One method of preventing pressure
build-up is to install an expansion tank for potable
water in the cold water supply line between the
heater and check valve. Contact your installing
contractor, water supplier, local plumbing
inspector or plumbing supply house for
assistance.
RECIRCULATION LINE (IF APPLICABLE)
If a recirculation line is installed, the return
connection should be made to a tee close to the
inlet connection on the water heater. A check
valve should always be installed in the
recirculation line to prevent cold water from
entering.
Use only clean copper or approved plastic pipe
for water connections. Local codes or regulations
shall govern the exact type of material to be used.
To minimize heat loss during non-draw periods, a
heat trap formed from piping can be used.

DOMESTIC HOT WATER TEMPERATURE
& PRESSURE RELIEF VALVE
An automatic temperature & pressure relief valve
with a temperature probe of sufficient length must
be installed at the time of the installation. No valve
of any type should be placed between the T&P
relief valve and the water heater. Use a tee to
install the relief valve onto the hot water outlet. The
pressure rating of the relief valve must not exceed
150 psi.
The BTU per hour rating of the relief valve must
equal or exceed the BTU per hour input of the
boiler(s) or heat source(s) as marked on the
boiler(s) rating plate.
For a circulating tank installation, the separate
storage tank(s) must have similar protection.
Connect the outlet of the relief valve to a suitable
open drain, so discharge can exit only 6” above the
structural floor; and cannot contact any live
electrical parts. The discharge line must pitch
downward from the valve to allow complete
draining (by gravity) of the relief valve and
discharge line, and be no smaller than the outlet of
the valve. 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. Local codes shall govern the
installation of relief valves.
THERMOSTATIC MIXING VALVE
When this water heater is supplying generalpurpose hot water requirements for use by
individuals, a thermostatically controlled mixing
valve is recommended to reduce the risk of scald
injury. Contact a licensed plumber or the local
plumbing authority for further information.
Keep temperature control of the mixing valve at the
lowest setting which is satisfactory.
When installing a mixing valve, locate it at the
bottom of anti-thermosiphon loop at least 24” high
to prevent excessive hot water from entering mixed
water supply.
VACUUM BREAKER (IF REQUIRED)
Install a vacuum breaker (or vacuum relief valve)
for water heater protection. Prevents siphoning of
the water from the system and collapse of the water
heater.

Operation
!
SAFETY PRECAUTIONS
Before operating this water heater, be sure to
read and follow these instructions, as well as
the warnings printed in this manual. Failure
to do so can result in unsafe operation of the
water heater resulting in property damage,
bodily injury, or death. If you have any
problems reading, following or difficulty in
understanding the instructions in this
manual, STOP, and get help from a qualified
person.
The maximum setting for the boiler water supply
to the heater coil is 210°F. The boiler supply
temperature should be from 20°F up to 40°F
higher than the domestic water temperature.
More exactly, the boiler supply temperature
should be higher than the domestic supply
temperature by more than half the boiler
temperature drop (TD) through the TURBOMAX.
Do not turn on the water heater unless it is
filled with water. Do not turn on water heater
if cold water supply shut-off valve is closed.
There is a Hot Water Scald Potential if the
controler is set too high.
After the water heater has been plumbed and
wired, it is now ready to be set for automatic
operation.
FILLING THE HEATER COILS
Make sure all drains valves on the cold or hot
water supply piping are closed.
Open the nearest hot water faucet and any
shutoff valves on the domestic hot water supply
piping from the heater’s domestic hot water outlet
(the top copper pipe connection).
Open the shutoff valve on the cold water supply
piping to the heater’s domestic cold water inlet.
When water discharges from faucet, close it.
Check for system leaks and repair if necessary.
Any other water faucets fed by this heater may be
opened to purge air from their supply piping, and
then shut off after a steady flow of water is
observed from the faucet.
OPERATING THE WATER HEATER
After the system has been manually purged of its
air, and all components (valves, vents,
controllers) have been set properly, the Eco
ULTRA boiler can be started. Never operate this
heater until this has been done.
Safety and energy conservation are factors to be
considered when setting the water temperature
on the controler. The most energy efficient
operation will result when the temperature setting
is the lowest that satisfies the needs consistent
with the application.
!
DANGER
When this water heater is supplying general
purpose hot water requirements for use by
individuals, a thermostatically controlled
mixing valve for reducing point of use water
temperature is highly recommended to
reduce the risk of scald injury.
Valves for reducing point-of-use temperature
by mixing cold and hot water are also
available. Consult a licensed plumber or local
plumbing authority for further information.
When the temperature of the boiler water in the
Eco ULTRA boiler is below the setting on the
control or aquastat, the circulator should start and
the boiler water will be heat by the renewable
energy source. The electric elements will turn
only if the temperature continue to decrease.
When the temperature of the boiler water in the
boiler reaches the temperature setting on the tank
control, the boiler and circulator should turn off.
On initial start-up with a cold tank, a considerable
amount of time may be required for the tank to
reach desired temperature.
Check the
temperature at a hot water faucet soon after the
burner has completed the first heating cycle.
Note that setting to a lower setting will not have
an immediate effect. The stored boiler water will
first have to be used. Additional checks of the
water temperature should follow completion of a
cycle. Further adjustments may be necessary as
you use your water heater and space heating
system.
ECO ULTRA Electric Boiler Installation, Use and Care Manual
(Revision June 2017),
Page 36.
OPERATING THE WATER HEATER WITH
A THERMOSTATIC MIXING VALVE
A thermostatic mixing valve provides for
automatic operation through the use of a
thermostatic element inside the valve. The
element will control the mixing of the hot and cold
water supply streams to provide a safe blend to
connected fixtures. This provides constant water
temperature under different working conditions.
When using models which are certified ASSE
1017 and, in addition, have successfully passed
the cold water supply failure test (ASSE 1016),
loss of either hot or cold water to the thermostatic
mixing valve will result in a reduction in flow from
the valve to less than .5 GPM within seconds of
the loss. Pressure difference between Hot and
Cold ports should not exceed 10 psi. Valves
require a minimum difference of 20°F between
the Hot and Mixed temperature for proper
operation.
To set the thermostatic mixing valve carefully
open a hot water tap. Protect yourself against the
risk of scalding. Use a thermometer and measure
hot water temperature form the faucet. Reduce
or increase the hot water temperature by
adjusting the valve knob to the proper position.
Lock the knob at the set temperature. Refer to
the valve manufacturer’s manual to get the proper
guidelines.
By mixing domestic cold water to the hot water
supplied by the heater, the thermostatic mixing
valve allows the boiler to work at higher
temperature range. Thus boiler water stored
inside the Eco ULTRA tank acts as a buffer which
increases boiler efficiency and the amount of
domestic hot water produced by the heater.
To increase hot water production and storage
capacity set the UltraSmart controller at a higher
temperature (from 140°F to 180°F).
And
secondly set the thermostatic mixing valve at the
desired temperature (from 90°F to 120°F).
For sanitation purposes use a different
temperature range or install a dedicated hot water
line to the equipment.

Maintenance
Properly maintained, your water heater will
provide years of dependable, trouble-free
service. It is recommended that a regular routine
maintenance program be established and
followed by the user. Components, however, may
be subject to failure that require service. Failure
to use the correct procedures or parts in these
circumstances may make the unit unsafe or
reduce the life of the heater.
chemical lime dissolving cleaners are preferred,
carefully follow the instructions supplied with the
cleaner. DO NOT use a muriatic or hydrochloric
acid (HCI) based cleaner. Be sure that the
manufacturer’s directions and warnings on the
container are followed. After treatment flush
cleaning solution thoroughly. Your plumbing
contractor should be contacted to clean the
heater of these deposits.
The owner should arrange to have the following
inspections and maintenance procedures done:
!
DANGER
Before manually operating the relief valve,
make certain no one will be exposed to the
danger of coming in contact with hot water
released by safety relief valves. The water
may be hot enough to create a SCALD hazard.
The water released should be directed to
suitable drain to prevent injury or damage
Domestic water piping:
 Yearly visual inspection.
Check all piping for signs of leakage at joints,
unions and shut-off valves. Remedy as needed.
Temperature & pressure valve:
 Yearly Inspection.
Must be manually operated to ensure safe and
proper operation. Make sure that the discharged
water is directed to a suitable drain or some
collection method, and will not spray onto any
person. Use lever on the temperature & pressure
valve to open. A steady discharge of hot water
should be noticed. After releasing this lever the
safety relief valve should close and fully shut off
this flow. If the temperature & pressure valve
does not function properly, it must be replaced
with the same model or its equivalent. Do not
plug the outlet of this valve if a dripping condition
occurs.
Scale:
 Monthly Inspection.
Scale problems occur rarely and under very
specific conditions. A domestic water flow rate
reduction may indicate scale build-up. A water
softener will prevent this problem.
A chemical cleaning process, however, is the
most effective process if done properly. If
