1.1.9. 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.

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.

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.

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.

› remove the boiler's front casing (refer to chapter

ACCESSING THE BOILER);

› loosen the screws in the gas 'B' discharge socket

(fig. 1) and insert the manometer.

FOR MAXIMUM DOMESTIC HEATING POWER USING METHANE

› Set the maximum domestic water temperature;

› turn on a domestic hot water tap as far as it

will go and check that the gas pressure on the manometer is compliant with the data indicated in the "TECHNICAL DATA" chapter;

› If not, remove the cap 'A' (fig. 1) and using a

10mm wrench, rotate nut 'C' (fig. 1) until the manometer indicates the correct pressure.

FOR MAXIMUM DOMESTIC HEATING POWER USING LPG

› Remove cap 'A' (fig. 1) from the modulator and

check that nut 'C' (fig. 1) is tightened completely.

› turn on a domestic hot water tap as far as it

will go and check that the gas pressure on the manometer is compliant with the data indicated in the "TECHNICAL DATA" chapter;

› If not, adjust the mains supply pressure regulator

until the manometer displays the correct pressure (if using mixed gas G30 - G31, regulate the input pressure of G31).

FOR MINIMUM DOMESTIC HEATING POWER

› Disconnect one of the two supply Fastons 'F'

(fig. 1) on the modulator 'E' (fig. 1) and check the gas pressure on the manometer complies with

the data indicated in the "TECHNICAL DATA" chapter;

› If not, keep nut 'C' in place with an open 10

mm wrench, and use a flat headed screwdriver to rotate screw 'D' (fig. 1) until the manometer indicates the correct pressure.

› reconnect the supply Fastom to the modulator

'E' (fig. 1);

› re-fit cap 'A' (fig. 1) to the modulator in the

original position for correct operation.

2.2.3. CHIMNEY SAFETY

The boiler is equipped with a flue safety thermostat device, which controls the correct evacuation of the combustion gases.

This device, by blocking the gas flow to the burner, put the boiler in safety if the flue hood has a partial or total obstruction, or the section is not suitable for the combustion gases exhaust.

In case of the flue safety thermostat intervention with consequent blocking of the boiler, it will be necessary to act promptly and appropriately to solve the defect of the flues exhaust.

DANGER

It is absolutely forbidden to tamper with the flue safety thermostat or to put it out of use, as this would compromise security.

In case of a block, before resetting the flue safety thermostat, proceed with the following operations:

› check the exhaust section;

› check that there are no obstructions that prevent

the correct flues exhaust.

Flue safety thermostat resetting:

› press the button placed between the two

electrical contacts of the flue safety thermostat (see fig.1);

› perform a test run on the flue safety thermostat,

checking with a tester the electrical continuity on the contacts. In case the flue safety thermostat is broken, replace it using only the original spare part;

› press the “RESET” button ‘

’.

2.2.17. GAS TYPE TRANSFORMATION

WARNING

Make sure that the gas adduction tube is suitable for the new type of fuel with which the boiler is supplied.

WARNING

Once transformation is complete, adjust the boiler again by following the instructions in the relevant paragraph and apply the new identification plate in the gas transformation kit.

WARNING

Remember that when using LPG gas, mechanical couplings must not be sealed with flax.

In order to carry out transformation, proceed as follows (see fig. 1):

1. cut off the electrical supply to the boiler;

2. close the gas tap;

3. remove the boiler's front casing and rotate the

control panel (refer to the 'ACCESSING THE BOILER' chapter).

4. unscrew the gas connector '1' using a 24mm

open wrench and separate the collector '2' from the burner '3' by unscrewing the screws '4';

5. replace the nozzles '5' on the collector using

a 7mm socket wrench. The nozzles must be refitted with new seals;

6. re-fit the collector '2' to the burner and replace

the connector '1'. After every dismantling and refitting of gas connectors, carefully check for any leaks by using soapy water;

7. affix the two 'gas data' stickers in the

transformation kit, one on the inside of the control panel covering the existing plate, and the other inside the front panel of the boiler, near the data plate. On the latter, data relating

to the old type of gas in use must be deleted with a permanent marker.

8. Set the parameter value for the new type of gas in use (see the instructions in the 'PARAMETER TABLE MIAB2013' and 'ACCESSING AND PROGRAMMING THE PARAMETERS' chapters);

9. adjust the minimum and maximum pressures (see the 'GAS PRESSURE CHECK AND CALIBRATION' chapter).
