FILLING THE INSTALLATION

The boiler may be filled by the drain tap. Filling should be
done at a slow flow rate in order to purge all the air
contained in the boiler by the upper point of the installation.
Filling is always done with circulating pumps stopped.

MOST IMPORTANT: start up after partial or
total drain of the installation:
If all air does not purge naturally via an opened expansion
system, then in addition to automatic airvents able to ensure
continuous automatic elimination of air from the system while
it is running, the installation must also include manual
airvents so that all upper points of the installation can be
vented and so that when the installation is full of water it can
be verified that all air is eliminated before the boiler are fired.
