1.1.2. BOILER LOCATION ENVIRONMENTAL REQUIREMENTS

The boiler has a thermal power over 35 kW and, therefore, it must be installed only into a heating unit.

BEFORE INSTALLING THE BOILER, THE INSTALLER MUST MAKE SURE THAT THE FOLLOWING CONDITIONS ARE MET:

› The device is connected to a heating plant and

a water supply network appropriate for its power and performance.

› The location must be properly vented through

an air vent.

› The air vent must be placed at floor level to

prevent it from being obstructed, protected by a grid that does not hamper the useful section of passage.

The device's installation location should be vented due to the presence of threaded joints on the gas adduction line. The location should be therefore provided with vents as to ensure air exchange, with output grid in the natural accumulation area of eventual gas losses.

WARNING

DO NOT install the boiler in a technical compartment near a swimming pool or a laundry, to avoid that the combustion air is exposed to chlorine, ammonia or alkaline agents that may worsen the corrosion phenomenon of the heat exchanger. Failure to observe this caution will void the warranty of the heat exchanger.

DANGER

Make sure that the tubes of the water and heating plant are not used as grounding system for the electrical plant. There are not suitable for such use.

WARNING

To prevent voiding the warranty and to ensure the proper operation of the boiler, please wash the plant (if possible when hot) with suitable pickling or descaling solutions in order to remove the impurities coming from tubes and radiators.

WARNING

When connecting the equipment to water supply, avoid excessive bending and recovery operations from any off axis positioning that may damage the tubes causing leaks, malfunction or early wear.

WARNING

In order to avoid any vibrations and noises, do not use tubes with small diameters or elbows with small radius and significant cut-off of the passage sections.

working the system pressure does not exceed the working pressure for each component.

WARNING

Ensure that, during the boiler operation, the system pressure doesn’t exceed the working pressure of each component.

WARNING

In order to prevent scales or deposits on the primary heat exchanger, the heating/D.H.W circuit inlet water must be treated according to the current regulations.

It is however suggested to treat the water:

› for the heating circuit, over 25 French degrees,

by means of chemical conditioning treatment for powers < 100 kW or sweetening for powers > 100 kW.

› for the D.H.W, over 15 French degrees, by means

of chemical conditioning treatment for powers < 100 kW or sweetening for powers > 100 kW.

It is also necessary to install a safety filter to protect the system.

WARNING

Connect the outlets of safety valves, three-ways valves (if present) and of the cylinder (if present) to an outlet funnel, to prevent the

1 Allacciamento idraulico_EN

boiler room from flooding if these devices cut in. This outlet should preferably be sent to the outside so as to avoid damage to persons or property caused by hot water in the event that the valve should open. The manufacturer is not responsible for any flooding due to the opening of the safety valve in case of system overpressure.

WARNING

On systems with a closed expansion tank, the pressure reducer on the automatic supply unit (where available) should be set to a pressure that will not exceed the initial design setting. Make sure that while the equipment is

a low temperature circuit, please install a safety thermostat on the heating flow, which can stop the boiler activity in case of high heating flow temperature. The company assumes no liability for damage caused to persons or for failure to comply with these instructions.

1.1.9. CHARACTERISTICS OF THE WATER OF THE SYSTEM

For a correct operation of the system, it is necessary to make sure that:

1. The system does not present losses or that the

most obvious are at least eliminated;

2. If an automatic filling system is present, a litre

meter must be installed in order to precisely know the extent of any losses;

3. The filling in of the system and the top ups are

performed with softened water in order to reduce the total hardness. The water must also be treated in order to maintain the pH within the provided threshold so as to avoid corrosion phenomena.

4. Either on new systems or on replacements, the

system must be fitted with efficient systems which ensure the elimination of the air and impurities: Y filters, micro impurity separators and micro bubbles of air separators;

5. Avoid draining the water of the system during the

routine maintenance even if it is about apparently insignificant quantities: for example, in order to clean the filters, provide the system with adequate shut-off valves;

6. Always perform an analysis of the water of

the system before opening the communication between the new generator and the system, in order to establish if the parameters present in the water indicate the need to fully drain the system, to use the water already present in the system or to chemically wash the system using utility water adding a detergent when it is suspected that the system might be dirty or particularly clogged and at the next loading with new treated water.

Water treatment

In order to preserve the integrity of the waterfume exchanger and to guarantee optimal thermal exchanges, it is necessary that the water of the primary circuit, circulating inside the exchanger of the condensate boiler, has the characteristics defined and constant in time. To obtain this, it is fundamental to perform a series of system preparation and maintenance operations such as:

• washing the system;

• check the characteristics of the water of the system;

The type of treatment to be performed will be chosen based on the characteristics of the water to treat, of the type of system and on the requested purity limits

Oxygen

A certain amount of oxygen always enters the system, both during the filling phase and during the use in case of reintegration or presence of hydraulic components without oxygen barriers. The reaction between the oxygen and the stainless steel creates corrosion and forms sludge. While the water fume exchanger is made of stainless steel, and therefore it is not subject to corrosion, the sludge created in the carbon steel system is deposited in the warm points, including the exchanger. This has the effect to reduce the heat capacity and thermally insulate the active parts of the exchanger, which might cause damages.

The precautions to limit the phenomena are:

- Mechanical systems: a deaerator combined with a sludge remover, correctly installed, reduce the quantity of oxygen circulating inside the system.

1 Riempimento dell'impianto_MIAH4_R1 K 100_v .2_EN

- Chemical systems: the additives allow the oxygen to dissolve in water.

R1BK_75-RAD-ING-Manuale-1810.1_SK.2

Page 17

Hardness

The filling and make-up water hardness brings a certain amount of limestone into the system. It attacks the warm parts of the exchanger, thus creating load losses and thermal insulation losses on the active parts. This phenomena can cause damages.

The filling and make-up water of the system, if it does not fall under the values indicated below, should be softened. Moreover, additives can be added in order to maintain the limestone into the solution. The hardness must be periodically checked and registered.

INSTALLER

Acidity 7 < pH < 8.5 Conductivity < 400 μs/cm (at 25°C) Chlorides < 125 mg/l Iron < 0.5 mg/l Copper < 0.1 mg/l

If the above indicated limits are exceeded, a water must be chemically treated.

The type of treatment to be performed will be chosen based on the characteristics of the water to treat, of the type of system and on the requested purity limits.

1.1.10. SYSTEM FILLING

WARNING

For system filling use only clean tap water. In order to prevent limestone build-up and damages to the domestic water heat exchanger, the hardness of the domestic supply water should not exceed 15° Fr. However, please check the characteristics of the water used and install suitable treating devices.

WARNING

If the system is filled by adding ethylene glycol-type chemical agents you have to install on the loading system a hydraulic trip unit in order to separate the heating circuit from the domestic circuit.

Before powering up the boiler, fill the system as follows:

8. If after performing these operations you observe a decrease of the water pressure inside the system, open once again the loading tap until the pressure gauge reaches the design pressure.

1. slightly loosen the cap of the jolly valve placed on the top of the condensing block to release the air form the top of the system (1-fig.1);

2. check that the jolly valves vent the air present in the system are not blocked;

3. connect a r ubber pipe to the draining tap placed on top of the condensing heat exchanger (2fig.1);

4. open the general domestic water input tap and load the system by exhaling all the air;

5. use pressure gauge present in the system to make sure that the system pressure reaches the design value;

6. after performing this operation, make sure that the loading tap is properly closed.

1.1.11. CONDENSATE DRAIN

FILLING THE CONDENSATE DRAIN SIPHON

Before starting the boiler you have to fill the condensate collection siphon in order to avoid fuel reflux through the siphon.

Fill the condensate collection siphon as follows:

› Unscrew the screw “P” (fig. 1), extract the siphon

and fill it with water up to the highest point “T” (fig. 1);

› Connect the adequately prepared flexible

condensate drain tube to a disposal system (it is necessary to neutralise the condensate if the material out of which the canal system where the condensate arrives is composed presents a corrosion risk; please see paragraph ‘CONDENSATE NEUTRALISER’). The condensate can be drained directly in the sewerage system by inserting an easily serviceable siphon.

WARNING

After the first months of operation of the device, it is recommended to clean the condensate collection siphon from any deposits deriving from the first transit of the condensate inside the technical components of the boiler. Such deposits might cause a malfunction of the siphon.

1 Scarico condensa_sifone recaplast_EN

CONDENSATE DRAIN

The heat generator produces a significant quantity of condensate during operation. This condensate has an acid pH of 3-5. Obser ve the national standard in force and the local regulations for the disposal of the condensate produced by the generator.

The designer, according to the power of the system and the intended use of the building, is bound to evaluate the acceptance of systems in order to neutralise the acid condensate.

The system must be performed so as to avoid the freezing of the condensate. Before putting into operation the device, check the correct evacuation of the condensate.

WARNING

Before connecting the condensate collection siphon to the drain tube, check that the slope of the boiler is ensured according to the indications from chapter ‘INSTALLATION OF THE GENERATOR’.

WARNING

Correctly connect the condensate collection siphon of the boiler to a draining system by adding the slope to the drain of the condensate of the fume exhaust duct. Where possible, it is recommended to perform such connection by means of a collection glass in order to check the correct discharge of the condensate avoiding stagnations that might cause dangerous returns of the condensate to the boiler.

In order to connect the condensate draining to the draining system, use only corrosion-resistant materials with an adequate diameter.

CONDENSATE NEUTRALISER

Assemble the condensate neutralisation box, fitted with granulate and active carbons for a treated power up to 350 kW (see fig.2). The device allows neutralising the condensate which is collected inside the thermal generators and/or in the fume discharge systems made of stainless steel, plastic, glass or ceramic.

The acid condensate, inserted into the neutralisation box, follows a mandatory path for two phases; the first one, filtration of nitrates and sulphates by means of active carbons contained in the first tube line, in the second one, the pH is increased.

The acidity of the condensate can be checked by using litmus paper in order to determine the pH. Then, the neutralised condensate can be transported into the sewage system.

Every six months, it is necessary to establish the PH of the treated condensate inside the neutraliser. Immerse a litmus paper (or a suitable digital tool) in the condensate near the tapped draining connection for about 2 seconds and thus lay it on a white paper. After about 30 seconds, it is possible to compare with the coloured scale. The neutral point is on the value 6.8-7; at a lower value, the condensate is acid, at a higher value, it is base].

If necessary, replace the active carbon and the reagent granulate.

1.1.12. ANTI-FREEZE PROTECTION

The boiler is protected against freezing thanks to the electronic board preparation with functions that start the burner and heat the concerned parts when their temperature goes below the minimum pre-set values, protecting the boiler up to an external temperature of -10 °C.

The device starts when the hot water temperature goes below 12°C, automatically starting the burner until the heating flow water temperature reaches the 30°C and, in presence of a return sensor, until the heating return water temperature reaches the 20°C.

The system starts even if on the display appears “OFF”, as long as the boiler is connected to the power (230 V) and gas supply.

1.1.17. FUME EXHAUST FITTINGS

WARNING

In order to ensure proper operation and efficiency of the device you have to connect the boiler fume exhaust fitting to the fume exhaust duct using appropriate polypropylene flue fittings for condensing boilers. It is recommended to install discharge systems approved by Radiant.

WARNING

You cannot use traditional flue fittings for the discharge ducts of the condensing boilers, nor vice versa.

WARNING

Ducts and fume exhaust duct must be adequately sized, designed and built according to the standards in force. They must be made of material adequate to the purpose, with special corrosion resistance, smooth on the inside and with hermetic sealed type. In particular, the junctions must have a condensate guard. Moreover, provide adequate condensate draining points, connected to the siphon in order to avoid that the condensate produced in the chimney goes into the generators.

› In order to discharge the fumes through a fumes

exhaust duct carefully follow the technical standards in force.

› Make sure that the discharge tube does not

protrude inside the fumes exhaust duct, stop before it reaches the inner surface of the latter.

› The discharge duct must be perpendicular with

the wall of the fumes exhaust duct.

› For all discharge ducts, with regard to the

fumes path, you should provide an uphill slope (outwards) so as to favour the reflux of the condensate towards the combustion chamber, suitably realized to collect and drain acid condensate.

› In case of horizontal co-axial system installation,

correctly place the horizontal co-axial terminal suitably realized to respect the slopes inside the fumes duct and to protect the air suction duct from adverse weather conditions.

› If a vertical fumes duct is installed, insert a

condensate collection siphon at the base of the duct connected to the sewerage system of the location.

2.2.15. SYSTEM EMPTYING

It is not recommended to empty the heating system as the changes of water generate the increase of limestone deposits inside the exchangers. In case it is necessary to protect against freezing the heating circuit by adding anti-freeze liquid to the system water, these products must be approved

SUPPORT CENTRE

by the company.

The possible limestone descaling of the elements of the boiler must be performed by means of the substances approved by the company, in compliance with what has been specified in the safety data sheet of the used product, ventilating the environment, wearing protective clothing, avoiding mixing different products, protecting the device and the surrounding objects.

2. MAINTENANCE

fig. 1

Whenever you need to empty the system, proceed as follows:

› turn off the main power supply switch;

› wait for the boiler to cool down;

› connect a flexible tube to the system emptying

outlet and connect the other end of the tube to a suitable discharge;

› rotate the RS draining tap of the boiler (fig. 1)

and, if installed, of the hydraulic compressor and of the collectors of the system;

› open the relief valves of the radiators starting

from the one at the top and continuing downwards;

› after draining out all water, close the relief

valves of the radiators and the emptying tap;

2 Svuotamento dell'impianto_R1K 100_SK.2_ EN

› if it is necessary to empty only the boiler, close

the delivery/return sectioning taps of the heating circuit and open only the draining tap placed on the lower part of the boiler and inserted in the pump collector.

2.2.16. FAULT SIGNALLING CODES

The fault signalling codes are displayed only on the display of the master control panel.

Except for the faults common for both units (as for example: E04, E78, E06, E99), the fault signalling code will be displayed with the prefix ‘01’ or ‘02’, which indicates that in that unit, there is a fault (01 = main master unit, 02 = secondary slave unit).

If there is a fault in both units, the display shows only the most serious signalling code. In order to view the next signalling code, press the ‘ will show the next alternating signalling code of the temperature of the collector. In order to manually reset the unit, press the RESET ‘

To view the last 5 fault signalling codes chronologically, starting with the most recent one, activate the ‘OFF’ mode by pressing the FUNCTION ‘
