7.1 System maintenance

7.1.1

Water level

Regularly check the level of water in the system and top up if
required, taking care that cold water is not added suddenly into the
boiler when it is hot.
The use of an automatic filling is strongly discouraged.
7.1.2

Draining

We advise you against draining the system unless it is
absolutely necessary.

7.2 Data plate

The rating plate fixed on the side of the boiler during installation is
used to identify the boiler correctly and also provides the main
specifications of the boiler.

This operation should be required only a few times in each heating
season, with very low quantities of water; otherwise, look for the leak
and repair it.
For example: Several months' absence with the risk of ice in the
building.
