8.CONNECTING THE APPLIANCE TO THE MAINS SUPPLY (NATURAL GAS CONNECTION)

Before installation, make sure that the local distribution conditions (nature and pressure of the gas) and the state of regulation of the appliance are compatible.

To connect the module to the gas supply, a flexible connection B is required which will enable connection to the gas inlet A. Always place a gasket C between the two connections (Fig.1) and tighten the components with a tightening torque of at most 10 Nm.

Fig. 1

Connection to the gas supply network can be made using a rigid copper hose or a flexible steel hose with a continuous wall and in compliance with the guidelines established by the standard UNI-CIG 7129. Once the operation is complete, check the hose fittings for leaks using a soapy solution; never use a flame.

For supplying it with other types of gas, see chapter “7. ADAPTATION TO DIFFERENT TYPES OF GAS”.

The gas inlet connection is threaded ½” external gas (ISO 228-1).

Connection with rigid copper hose: The connection to the gas supply network must be

carried out in such a way that it does not cause stresses of any type on the appliance. The connection can be made using the adapter unit D with double cone, always inserting the supplied

gasket C in between. Tighten the components with

a tightening torque of at most 10 Nm. Connection with flexible steel hose: Use only

continuous wall stainless steel hoses that comply with standard UNI-CIG 9891, making sure to always insert the supplied gasket C between the connection B and the flexible hose E. Tighten the components with a tightening torque of at most 10 Nm.
