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; you should also make sure
that the shut-off valve is the right size and that it is connected
correctly.
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.

Water connection

The illustration below shows the connections for the water and
gas attachments of the boiler. See valves configuration on page
1.
For the measuring of the pipes and of the heating bodies in the
heating system, the residual head value should be calculated as a
function of the requested flow rate, in accordance with the values
shown in the circulation pump graph on page 14.
