Gas connection

Make sure, using the labels on the packaging and the
data plate on the appliance itself, that the boiler is
in the correct country and that the gas category for
which the boiler was designed corresponds to one of
the categories available in the country where it will
be used.
The gas supply piping must be created and measured
out in compliance with specific legal requirements
and in accordance with the maximum power of the
boiler; ensure the gas isolation valve is connected
correctly, see drawing opposite.
Check that the supplied gas corresponds to the type
of gas for which the boiler was designed (see the
data plate located on the appliance itself ).
It is also important to check that the pressure of
the gas (methane or LPG) you will be using to feed
the boiler is suitable, because if it is insufficient the
power may be reduced, causing inconvenience for
the user.
