1.5 REGULATIONS FOR INSTALLATION

ARES Tec is a gas category II

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

Installation must be carried out by a professionally authorised 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.

heating 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.

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 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, 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.

Example of water treatment unit

ATTENTION! These appliances are designed and developed to transfer heat to a heat carrying uid possessing the characteristics described here, they are not suitable to directly heat water intended for human consumption.

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 hydraulic separator.

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).

Before igniting the generator, ll the trap through the relative cap.

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.

3.12 FLUE EXHAUST MANIFOLD CONNECTION

To secure the ue exhaust manifold use the 6 nuts + CH 10 washers contained in the bag.

e ue point must be positioned on the rst straight section, within 1 meter of the boiler.

To set up the ue inspection point, cut a Ø 21 mm hole in the ue exhaust pipe, and install the inspection point following the sequence provided.

3.13 ELECTRICAL CONNECTIONS

GENERAL RECOMMENDATIONS

Electrical safety of the appliance is only ensured when it is correctly connected to an ecient earthing system as specied by current safety standards: gas, water and heating system pipes are not suitable in any way whatsoever as earthing connections.

It is necessary to check this fundamental safety requirement; In case of doubt, have an accurate inspection of the electrical system carried out by professionally qualied personnel, as the manufacturer is not responsible for any damage caused by the lack of a earthing connection in the system. Have professionally qualied personnel make sure the electrical system is suit-

able for the maximum power absorbed by the appliance, as stated on the plate, making sure in particular that the section of the system's cables is suitable for the power absorbed by the appliance.

For the main power supply to the appliance, never use adapters, multiple sockets and/or extension leads.

The use of components involving use of electrical power requires some fundamental rules to be observed such as:

- do not touch the appliance with wet and/or moist parts of the body and/or barefoot;

- do not pull the electric cables;

- the appliance may not be used by children or unskilled individuals

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.

GRUPPO DI 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.

3.18 CHECK THE ADJUSTMENT OF THE PRESSURE TO THE BURNER

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!

Remove cap 2, attach the red cap 3 to the ue point 1. Place the CO2 analysis probe 4 in the hole on the cap. Once the measurement has been made, take the cap out and use the relative cap 2 to close the ue exhaust point back up.

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.

Instructions for the installer

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 limits.

When replacing the gas valve or having diculty with ignition:

Screw general adjusting screw "A" on clockwise until it stops, then unscrew by 7 revolutions. Check boiler ignition. If it does not start up unscrew screw "A" by one more revolution, then try to start it up again. If the boiler does not start up again, follow the operations described above until the boiler does start up again. At this point adjust the burner as previously illustrated.

Nozzles - pressures.

Frequently check the CO2 levels, especially at low ow rates.

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 force;

- the power supply for the boiler is 230V - 50Hz;

- the system has been lled with water (pressure gauge 0.8/1 bar with

the pump o);

- any cut-o dampers on the system are open;

- the required gas corresponds to the one used for boiler calibration:

otherwise have the boiler converted for use with the available gas (see section: "ADAPTATION FOR USE WITH OTHER GASES"); this operation must be carried out by authorised company in accordance with regulations in force;

- the gas supply valve is open;

INSPECTIONS AND

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!

Relation between the temperature (°C) and nom. resistance (Ohm) of the heating probe SR and the heating return probe SRR. Example: At 25°C, the nominal resistance is 10067 Ohm At 90°C, the nominal resistance is 920 Ohm

Be careful during the maintenance operations.

STD.005726/000

Page 45

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.

Inspections and maintenance

- Take out: all of the casings and act on the two closing hinges to take o the cover.

- Take out the rear casing clamping screw on the right and le side.

STD.005726/000

- Take out the side clamping screws (right/le side).

- Take out the closing plate clamping screws (ue exhaust output side) and take o the casing.

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.
