Commissioning - Lamborghini Caloreclima GASTER N 119 AW Instrucciones De Uso, Instalación Y Mantenimiento

Gas conversion
The unit can run on Natural gas (G20-G25) or liquefied gas (G30-G31) and is factory-set for use with natural gas, as clearly shown on the
packing and on the data plate. Whenever the unit has to be used with a different gas, a conversion kit will be required, proceeding as follows.
From natural gas to liquefied gas
1. Replace the nozzles at the main burner and pilot burner, fitting the nozzles specified in the technical data table in par. 4.3.
2. Remove the small cap 3 (fig. 8) from the gas valve, screw the ignition "STEP" regulator 2 (contained in the conversion kit) onto the valve
and refit the cap 3 on the regulator.
3. Adjust the burner gas pressures, for minimum and maximum power as described in the previous section, setting the values given in the
technical data table in par. 4.3.
4. Operations 2 and 3 must be performed on all the valves.
5. Apply the sticker contained in the conversion kit, near the data plate as proof of the conversion.
From liquefied gas to natural gas
Carry out the same operations described above, making sure to remove the ignition "STEP" regulator 2 in fig. 8 the gas valve; the cap 3
in fig. 8 must be fitted directly on the valve.

3.2 Commissioning

Commissioning must be carried out by Qualified Personnel.
The following operations and checks are to be carried out at first lighting, and after all maintenance work involving disconnection from the systems or
work on safety devices or parts of the boiler.
Before lighting the boiler:
• Open any shutoff valves between the boiler and the system.
• Check the tightness of the gas system, proceeding with caution and using a soapy water to detect any leaks in the connections.
• Fill the water system and make sure all air contained in the boiler and the system has been vented by opening the air vent valve on
the boiler and any vent valves on the system.
• Make sure there are no water leaks in the system or boiler.
• Make sure the electrical system is properly connected.
• Make sure the unit is connected to an efficient earthing system.
• Make sure the pressure and gas flow values are those required for heating.
• Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler
