e appliance must be installed in accordance with the instructions
contained in this manual.

Installation must be carried out by a professionally author ised company,

who is in charge of enforcing observance of all local and/or national
laws published in the Ocial Gazette, as well as all applicable
technical regulations.

It is necessary to observe the standards, regulations and requirements
for installation provided below, constituting a rough and non-exhaustive
list, in order to follow the evolution of the "state of the art". We

would like to underline that updating the list of standards is the
responsibility of the technicians authorised to carry out installation.

heat unit.

2H3P

Also observe the standards regarding the heating control unit,
construction regulations and requirements on combustion heating in
the country of installation.

The appliance must be installed, commissioned and subject to
maintenance in accordance with the current "state of the art". is also
applies to the hydraulic system, the ue exhaust system, the installation
room and the electrical system.

Failure to observe the above regulations will void
the warranty.

1.6 INSTALLATION

When the appliance is installed on existing systems, make sure that:

- e ue is suitable for condensation appliances, for the temperatures
of the combustion products, calculated and built in accordance with
regulations in force. at is it a straight as possible, water-tight and
insulated and does not have any obstructions or constrictions.

- e ue is equipped with an attachment to evacuate the condensation.

- e heating control unit is equipped with a pipe for the evacuation
of the condensation produced by the boiler.

- e electrical system is built in accordance with specic regulations
and by professionally authorised company.

- e ow rate, head and direction of ow of the circulation pumps is
appropriate.

- e fuel feed line and any existing tanks are set up in accordance with
regulations in force.

- e expansion vessels ensure complete absorption of the dilation of
the uid contained in the system.

- Slurry and build-up have been cleaned out of the system.

If ARES Tec is being installed on existing Systems:

If it is possible to schedule the replacement, it is necessary to wash

the system preventively, with alkaline dispersants. Washing must be
carried out four weeks prior to replacement, with a system operating
between 35°C - 40°C.

Attention!
If the new boiler has been replaced in an old system
without having preventively washed it as described
above, do not wash the system, as any residues of
the product in the circuit may ll the generator with
residues aer replacement.
It is advisable to contact a company specialised in
water treatment.

Otherwise, if ARES Tec is being installed on a new system it is advisable
to wash it thoroughly in any case, using products that are suitable for
the entire system, and install a Y-strainer with two cut-o valves on the
return pipe to the boiler, so that it can be cleaned as needed.
is lter will protect the boiler from sediments coming from the
heating system.

In both cases it is necessary to keep the head losses localised in the
primary circuit, for the correct sizing of the pump.

General information

1.7 WATER TREATMENT

Treating the supply water allows you to prevent problems and
maintain the functionality and eciency of the generator over time.

e purpose of this treatment is to eliminate or signicantly reduce
problems that can be outlined as:
build-up
corrosion
sediments
biological growth (mould, fungus, algae, bacteria, etc.)

e chemical analysis of the water provides a lot of information on the
state and "health" of the system.
e pH level is a numerical indication of the acidity or alkalinity of
a solution.
e pH scale goes from 0 to 14, where 7 corresponds to neutral.
Values below 7 indicate acidity, values above 7 indicate alkalinity.

e ideal pH value in heating systems with aluminium boilers is
between 6.5 and 8,5, with a hardness of 15°F.

Water in a system with a pH value outside of this range considerably
accelerates the destruction of the protective oxide layer which forms
naturally inside the aluminium bodies, and would not occur naturally:
if the pH level is lower than 6,5 it contains acid, if it is above 8,5 the
water is alkaline, either due to an alkaline treatment (for example
phosphates or glycols operating as antifreeze) or in some cases the
natural generation of alkalis in the system.
Vice versa, if the pH value is between 6,5 and 8,5, the aluminium
surfaces in the body are passivated and protected from further corrosive

attacks.

To minimise corrosion, it is essential to use a corrosion inhibitor.
In order for it to work eciently, however, the metal surfaces must
be clean.
The best inhibitors on the market also contain an aluminium
protection system that stabilises the pH levels of the ller water,
preventing sudden changes (buer eect).
It is advisable to systematically check (at least twice a year) the
pH value of the water in the system. In order to do so a chemical
laboratory analysis is not required, but a simple check using a
analysis "kit" contained in a carry cases, easily available on the
market.

It will therefore be necessary to set up the devices shown in the gure

in the heating system.

THE COUPLING MUST BE SET UP ON THE
RETURN PIPE TO THE PRIMARY CIRCUIT
DOWNSTREAM OF THE PUMP.

All of the precautions required to avoid the formation and localisation of
oxygen in the water of the system. For this reason the plastic pipes used
in the under-oor heating systems must not be permeable to oxygen.

Make sure that any anti-freeze products are compatible with aliminium
and any other parts and materials in the system.

ATTENTION!
Any damage caused to the boiler, due to the formation
of build-up or corrosive water, will not be covered by

the warranty.

out before covering the pipe.

Danger!
e gas connection must be set up by an authorised
installation technician who must observe and apply
the contents of the legislation in force and the local
requirements of the gas supply company, as incorrect
installation can cause damage to people, animals
and property, for which the manufacturer will not
be held liable.

Before installation it is advisable to clean the inside
of the fuel intake pipe thoroughly, in order to remove
any residues that could stop the boiler from operating
sm oot hly.

If you notice the smell of gas:
a) Do not work the electrical switches, the telephone

or any other object that can generate sparks;

b) Immediately open doors and windows to create an

air current that puries the room;
c) Close the gas valves;
d) Seek the assistance of professionally qualified

personnel.

In order to prevent any gas leaks it is advisable to install

3.9 DETERMINING THE PRIMARY
CIRCUIT PUMP OR BOILER PUMP

Immergas provides a series of primary rings complete with an accurately
sized pump, if alternative solutions are being used, the boiler pump
must have a head that is capable of ensuring the ow rates represented
in the "Water side head losses" graph.

e pumps must be determined by the installer or
designer based on the data for the boiler and system.
e resistance curve on the water side of the boiler is
represented in the table provided below.
e pump is not an integral part of the boiler.
It is advisable to choose a pump with a ow rate and
head of approximately 2/3 of its typical curve.

e table below roughly indicates the ow rates of the pump based
on the Δt of the primary circuit if the installation is equipped with a

3.10 CONDENSATE DRAIN

e condensate drain into the sewer must be:

- built to avoid gaseous combustion products from leaking out into the
environment or the sewer (trap).

- sized and built to allow liquid discharge to runo correctly, preventing
any leaks (gradient of 3%).

- installed to avoid the liquid contained in it from freezing, under the
envisioned operating conditions.

- can be easily inspected from the relative trap

- mixed with household wastewater, for example, (washing machine
and dish washer drains etc.) with a mainly alkaline pH so as to form
a buer solution to send it into the sewers.

e condensate must not be le to stagnate in the combustion product
drainage system (for this very reason the evacuation pipe must be set
up at an inclination of at least 30 mm/m, running towards the drain)
except for any liquid head, in the drain trap of the combustion product
evacuation system (which must be lled aer installation and at a
minimum height with all of the fans operating at maximum speed of
at least 25 mm) - see gure.

It is forbidden to drain the condensate towards rain pipes, given the
risk of ice and degradation of materials normally used to build the rain
pipes themselves.

e drain tting must be visible.
Given the degree of acidity of the condensate (pH between 3 and 5)

suitable plastic materials must be used to build the drain pipes.
e condensate drain pipe outlet is set up towards the connection

side of the ue box manifold, removing the pre-sectioned part on the
cover panel.

e recommended material for use must be PE (polyethylene) or PPI
(polypropylene).

3.11 CONNECTING THE FLUE

Exhaust is discharged at very low temperatures (Max 84°C approx) in
condensation boilers. It is therefore necessary for the ue to be perfectly
impermeable to combustion product condensate and built with suitable
corrosion-resistant materials.
e various slip on joints must be well-sealed and equipped with suitable
gaskets to stop condensation from leaking out and air from getting in.
In terms of ue section and height, it is necessary to refer to national
and local regulations in force.
Refer to regulations in force for sizing.
In order to avoid the formation of ice during operation, the temperature
of the inside wall at every point in the combustion product evacuation
system, for its entire length, must not drop below 0°C.
For condensation operating conditions of the appliance at project
outdoor temperatures, it will be necessary to build a confluent
condensate drainage system, based on the installation conditions, either
to the boiler collection tank or separate from it.

The flue exhaust pipe must comply with local and national
regulations.
e evacuation pipe must be built using materials that are resistant
to the combustion products, typically class W1 certied stainless
steel or plastic materials.

Such as PVDF (polyvinyldimethyluoride) or PPS (simple translucent
polypropylene) or aluminium or other materials with the same features,
in observance of regulation in force.

e supplier is excluded from any contractual and
extra-contractual liability for damage caused by
errors in installation and use and nevertheless due
to failure to observe the instructions provided by
the manufacturer.

Instructions for the installer

Danger!
Electrical installation must only be carried out by an
authorised company.
Before setting up the connections or any operation on
the electrical parts, always cut-o the electrical supply
and make sure it cannot be accidentally re-connected.

e electrical supply to the boiler, 230 V - 50 Hz single
phase, must be carried out on point A, included, with
a H05VV-F (PHASE - NEUTRAL - GROUND) three­pole cable with a section between 0.75 mm and 1.5 mm.
is connection must be set up by state of the art, as
envisioned by regulations in force.

External probe connection

Remember that it is necessary to install a bipolar
switch on the electrical supply to the boiler with a
max distance between the contacts of 3 mm, easy to
access, so that maintenance operations can be carried
out quickly and safely.

ATTENTION!

Respect the PHASE and NEUTRAL polarity since
ame detection is Phase Sensitive.

3.16 SYSTEM FILLING AND EMPTYING

Attention!
Do not mix the heating water with antifreeze or anti­corrosion substances at incorrect concentrations!
This may damage the gaskets and cause noise to
develop during operation.
Immergas will not be held liable in case of damage
caused to people, animals or property due to failure
to observe the above.

Once all of the connections for the system have been set up, it is possible
to ll the circuit.

EXAMPLE OF SYSTEM LOADING UNIT

To ll the system it is possible to set up a loading valve on the system's
return pipe.

It can also be lled through the drain valve installed on the boiler
return manifold.

e boiler is equipped with an emptying valve, positioned as indicated
in the gure of parag. 2.2. is valve must never be used to empty the
system, since all of the dirt contained in the system may accumulate
in the boiler, jeopardising smooth operation. Accordingly, the system
must be equipped with its own emptying valve, of a suitable size for
the ow rate of the system.

CARICAMENTO

UNIT

3.17 BOILER FROST PROTECTION

If the ow temperature (measured at the global ow NTC) should fall
below 7°C the system pump starts operating.
If the temperature drops any further (under 3°C), all modules are
commissioned at the minimum power until the return temperature does
not reach 10°C. is device protects the boiler only. In order to protect
the system as well, it is necessary to add antifreeze liquid.

NB: e antifreeze liquid must be compatible with materials present
in the entire system and tolerable for aluminium alloys.

ATTENTION!

All of the instructions below are provided for the
exclusive use of authorised assistance personnel.

All boilers leave the factory calibrated and approved,
nevertheless, if the calibration conditions need to be
changed it is necessary to re-calibrate the gas valve.

ATTENTION!

Place the CO
Once the measurement has been made, take the cap
out and use the relative cap 2 to close the ue exhaust
point back up.

ATTENTION!

To access the gas valves more easily, unhook electric
panel "A" by acting on spring "B" (right and le).

Turn electrical panel "A" slightly and lower tilting

Instructions for the installer

A) Adjustment at maximum power.

- Unscrew the closing cap for ue exhaust analysis point.

- Place the analyser probe inside the ue analysis point.

- Make burner 1 operate at max power, following the procedure

illustrated below in "chimney sweep function " (100 % CASC
MANUAL).

- Make sure that the CO2 level falls within the values indicated in the

"Nozzle pressure" table.

- Possibly correct the value by turning adjusting screw "A" CLOCKWISE

to decrease it and COUNTER-CLOCKWISE to increase it.

B) Adjustment at minimum power.

- Make burner 1 operate at min power, following the procedure

illustrated below in "chimney sweep function " (10 % CASC
MANUAL).

- Make sure that the CO2 level falls within the values indicated in the

"Nozzle pressure" table.

- Possibly correct the value by turning adjusting screw "B" CLOCKWISE

to increase it and COUNTER-CLOCKWISE to decrease it.

Follow this procedure to adjust the other modules
as well.

If the measured ow rate is too low, make sure the supply and draining
systems (the supply and draining pipes) are not obstructed.
If they are not obstructed, make sure the burner and/or exchanger
are not dirty.

C) Completing basic calibration.

- Check CO2 values at the minimum and maximum ow rate.

- Touch up if necessary.

For smooth operation, calibrate the CO2 values taking
care to observe the values in the table.

- Close the cap for the ue inspection point back up.

NOTE: do not force the adjusting screw limit switch

3.20 FIRST IGNITION

Preliminary checks.

First ignition must be carried out by professionally
authorised company. Immergas will not be held
liable in case of damage caused to people, animals or
property due to failure to observe the above.

Danger!
Prior to commissioning the appliance ll the trap
through the ller hole and make sure the condensate
is draining correctly.
If the appliance is used with an empty condensate
drain trap the danger of poisoning subsists following
a ue gas leak.

Prior to commissioning the boiler it is advisable to make sure that:

- installation fulls the standard specications and requirements in

force for both the gas and electrical part;

- the supply of combustion air and the evacuation of ue exhaust are

carried out correctly in accordance with standard specications and
requirements in force;

- the fuel supply system is sized for the boiler's ow rate and is equipped

with all of the safety and control devices required by regulations in

MAINTENANCE

4.1 INSTRUCTIONS FOR INSPECTION
AND MAINTENANCE

Inspections and maintenance carried out to state
of the art and at regular intervals, as well as the
exclusive use of original spare parts, are of primary
importance for smooth operation and to guarantee
long boiler life.
Annual maintenance of the appliance is compulsory,
in accordance with Legislation in force.

Failure to carry out Inspections and Maintenance can
cause material and personal damage.

For this reason we recommend stipulating an inspection or maintenance
contract.

Inspection is required to determine the eective state of an appliance
and compare it with the optimal state. is is carried out through
measuring, checking, observing.

Maintenance is required to eliminate any deviation of the eective state
from the optimal state. is is usually carried out through cleaning,
setting and possibly replacing single parts that are subject to wear.

ese maintenance intervals are set forth by a specialist based on the

certied state of the appliance at the time of inspection.

Instructions for inspection and maintenance.

Only original spare parts must be used to ensure a
long life for all of the functions of your appliance,
and to avoid changing the conditions of the approved
standard product.

Before proceeding with maintenance operations, always carry out the
procedures described below:

- Turn o the mains switch.

- Separate the appliance from the electrical network using a separation
device, with a contact opening of at least 3 mm (for ex. safety devices
or power switches), and make sure it cannot be accidentally re­connected.

- Shut the gas cut-o valve upstream of the boiler.

- If necessary, and based on the work that needs to be carried out, close
any cut-o valves on the heating ow and return.

Once the maintenance work has been nished, always carry out the
operations listed below:

- If necessary, open the heating ow and return

- Relieve and, if necessary, restore the pressure in the heating system.

- Open the gas cut-o valve.

- Re-connect the appliance to the electrical network and engage the
mains switch.

- Make sure the appliance is water-tight, on the gas side and the water
side.

OBLIGATION!

Wear protective gloves.

Scalding hazard!

Inspections and maintenance

We urge you to have authorised company fulfil
requirements regarding periodic maintenance
checks.

Since dust is extracted from the inside, the resistance on the ue side,
through the boiler, will increase, leading to a decrease in the heat load
(and, consequentially, in the power).
Prior to cleaning, check the heat load and the percentage of CO2. If
the measured load (with a correct CO2 level) is within 5% of the value
indicated in parag. 3.18, the boiler does not need to be cleaned.
e operation must therefore be limited to cleaning the trap.

ATTENTION!
A drop in the heat load can be caused by an obstruction
in the exhaust channel or air intake pipe. First of all
make sure that this is not the cause.

If there is a drop in the heat load greater than 5%, check
how clean the burner condensate-collection pan is. Also
clean the trap.

First phase – Disassembly.

- Shut o the electrical and gas supplies making sure the valve is rmly

shut.

- Take out: all of the casings.

- Act on the two rear closing hinges to take out the cover.

- Turn the required screw to li the cover.

- Take out the rear, front and side casing clamping screws.

- Take out the two cover clamping screws.

Inspections and maintenance

Second phase – Cleaning.

- Take out the gaskets and burners.

- Dry clean the burners using compressed air and operating from the
"ame side".

- Visually check the state of the welding on the angulars and burner
mesh.

The burner gaskets must be replaced every time
cleaning operations are carried out.

- Wash the combustion chamber with water being careful not to get
the electrical cables wet.

- During this operation is necessary to make sure that the condensate
exhaust pipe is always unobstructed so that the wash water does not
leak out from the inspection opening.

- Blow the combustion chamber with compressed air to remove any
dirt that is still attached to the studs.

- When the elements have been washed make sure that the condensate
drain trap is unobstructed: clean if necessary.

- Inspect the exhaust evacuation pipe and the ue.

ird phase - Reassembly.

- Once the body and/or burners have been cleaned, put the burners
back in their places.

- Put the new graphite gaskets in place.

Proceed in the reverse order for reassembly, being
careful to tighten the screws that clamp the mixer
unit/fans to the body, at a torque of 13 Nm.

ATTENTION
IT IS NECESSARY TO CHANGE THE SEALING
GASKETS ON EACH BURNER AT EVERY
MAINTENANCE OPERATION.

- Prior to ignition, make sure the condensate drain trap is full of water.

- Before opening the gas supply valve make sure that the previously
loosened gas tting is rmly tightened. In order to do so open the
valve and check the seal using soapy water.

- As a burner is being ignited, immediately check the seal between each
single gas valve and relative premixing chamber.

- Perform a combustion analysis and check the parameters.

- Make sure that all of the previously opened gas pressure points are
closed.
