ATTENTION !!! It is prohibited to operate the
appliance with the incorrect gas type. Ceck the data
label on the appliance for Natural gas (G20) or Propane
gas (G31) to ensure that the correct appliance in being
installed.
ATTENTION !!! Check that the gas and supply
pressure are those for which the appliance has been
adjusted.
Two situations are possible:
A - the gas and supply pressure correspond to the
adjustment of the appliance. In this case, it can be
connected;
B - the gas and supply pressure do not correspond to the
adjustment of the appliance. In this case, the appliance
must be converted to the type of gas and supply
pressure corresponding to those of the supply available.
The appliance is provided with the relevant gas conversion
kit.
Before the gas pipes are purged it is essential to ensure
that the internal surfaces are clean and free of metal or
plastic filings or any other solid pieces or liquids;
An isolation valve must be installed on the gas supply
pipe adjacent to the appliance;
ATTENTION !!! Before supplying gas to the
appliance, it is essential that the gas pipes have been
pressure tested in accordance with the most recent
applicable gas standards.
to prevent damage to the appliance gas valve, the
supply pressure should not exceed 50 mbar under any
circumstances;
if the gas pipe-work must be tested in excess of 50
mbar, ensure that the appliance is fully isolated.
Figure 5.2 shows the position and the diameter of the gas
connection on the appliance. Ensure that the gas service pipe-
work is adequately sized to provide the maximum volume flow
rate at the required minimum pressure.
