1.1.9. SYSTEM ACCESSORIES

DIVERTER VALVE KIT

The kit allows combining the thermal generator with a remote boiler for the production of domestic hot water (cod. 26097LP, fig. 1).

In this configuration, it is possible to manage the domestic circuit in an independent manner, by implementing a diverter valve which ensures the power supply of the serpentine upon the preheating request of the boiler.

The kit is completed with a probe for the external boiler and with a power supply cable of the diverter valve which is connected directly to the electronic board of the generator.

1. INSTALLATION

HYDRAULIC SEPARATOR

In order to always ensure to the heat generator an operation without problems related to two low heat capacities (due, for example, to closed radiators or to impurities of various type), it is strictly necessary to install a trip unit, as an alternative, a heat exchanger which separates the hydraulic circuit.

Choosing a separation system in the detriment of another is exclusively imposed by the type of the system.

In case of a new system o r in case of replacem ent of the generator with the possibility to wash the water pipes, it is recommended to install a hydraulic separator (code 26205LA, fig. 1).

The hydraulic separator creates an area with reduced load loss, which allows hydraulically rendering independent the primary and secondary circuits connected to it. With the hydraulic separator you can thus have a production circuit with constant heat capacity and a distribution circuit with variable heat capacity, operation conditions typically specific to modern air-conditioning systems.

fig. 1

R1K 50 - RAD - ING - Manuale - 1801.1_SK.3

Page 15

Particular attention should be given, during the design phase, to possible temperature variations to which the circuits can be subject due to the generated mixing inside the hydraulic separator.

A secondary circuit with a heat capacity higher than the circulatory one of the primary circuit generates, in fact, by means of the hydraulic separator, a delivery temperature lower than the one of the primary circuit.

INSTALLATION ON SELF-SUPPORTING FRAME

WARNING

During the installation of the heat generator, pay maximum attention to the installation of the self-supporting frame. The frame must rest on a perfectly flat surface and, when supported against the wall, the latter must be perfectly angled. The incorrect slopes of the device can cause the incorrect discharge of condensate by means of the discharge duct with consequent condensate stagnation inside the condensate module. The correct installation of the frame allows obtaining, acting on the lower bracket, a counterslope of the device against the perpendicular.

In order to mount the frame and therefore the generator, proceed as follows:

1. check the angle of the wall with the floor;

2. assemble the side profiles 3 and 4 on the pillars 1 and 2 (fig. 1);

3. assemble the side pillars 1 and 2 on the horizontal crossbeam 5;

4. assemble the central crossbeam 8 and the lower one 7;

5. complete the assembly, position the frame binding it to the wall 9 (if provided) and on the floor 10;

6. mount the upper bracket 6 and hook the eyelets of the boiler into the adequate hooks 11;

7. make sure that the frame is angled, adjust the inclination of the boiler by means of the lower bracket

(see "Wall mounting by means of fixing bracket") ensuring an inclination of the boiler, against the vertical, of about 1–1.5°;

1.1.12. HYDRAULIC CONNECTION

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

If the boiler is installed in a hydrostatic position lower than those of the user devices (radiators, fan coils, etc.), mount the shut-off valves on the domestic water heating circuit to ease the performance of the maintenance operations if it is necessary only to empty the boiler.

DOMESTIC CIRCUIT

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 °f. However, please check the characteristics of the water used and install suitable treating devices.

The heat exchanger coil cleaning frequency depends on the hardness of the supply water and on the presence of solid residues or impurities inside the water that are often present in case of recently installed plants. Based on the characteristics of the infeed water, you should install suitable water treating devices, for residues presence please install a line filter.

The pressure of the cold infeed water should be between 0.5 and 6 bar. In case of greater pressure values, please install a pressure reducer upstream from the boiler.

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.

WARNING

Connect the boiler safety drains to a discharge funnel. The manufacturer is not responsible for any floods due to safety valve opening in case of plant overpressure.

HEATING CIRCUIT

In order to avoid any scale or deposits on the primary exchanger, the hardness of the heating circuit infeed water should not exceed 25 °f. However, please check the characteristics of the water used and install suitable treating devices.

This treatment is mandatory if frequent episodes of return water or partial or total emptying of the plant occur.

WARNING

In case the boiler is installed as part of 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.

1.1.13. CHARACTERISTICS OF THE

Water treatment

WATER OF THE SYSTEM

In order to preserve the integrity of the water-

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;

1 Riempimento dell'impianto_MIAH4_R1K 10 0_v.1_ EN

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.

fume 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.

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

R1K 50 - RAD - ING - Manuale - 1801.1_SK.3

Page 22

INSTALLER

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.

1. INSTALLATION

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.

1.1.14. 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:

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 (fig.1);

2. check that the jolly valves vent the air present

in the system are not blocked

3. open the general domestic water input tap and

load the system by exhaling all the air;

4. use pressure gauge present in the system to

1 Riempimento dell'impianto_MIAH4_R1K 10 0_v.1_ EN

make sure that the system pressure reaches the design value;

5. after performing this operation, make sure

that the loading tap is properly closed.

6. Open the air relief valves of the radiators and

check the air removal process. When the water starts to leak close the radiators air relief valves.

1.1.16. 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.

1.1.21. 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

For fumes exhaust and condensate collection, please follow the technical standards in force.

› 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.

› The discharge duct must be perpendicular with

the opposite internal wall of the chimney or of the fumes exhaust duct (fig. 1).

fig. 1

1 Raccordi fumari_cond_EN

› For all air suction ducts, with regard to the air

path, you should provide an uphill slope (towards the boiler) so as to avoid the protrusion inside the duct of rain water, dust or foreign objects.

› 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.

› In order to discharge the fumes through a fumes

exhaust duct carefully follow the technical standards in force.

› Make sure that the discharge tube doe not

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