accessories to Be Installed on the System
Before switching the boiler on, let water circulate (with boiler off) for at least 2 hours in
order to eliminate any impurity from the system through the micro-air bubbles separator
and micro impurity separator. During this last phase, open the drain cock fitted onto the
micro impurity separator at regular intervals, so as to eliminate any deposit. (Repeat this
operation also during the first heating phase).

As an alternative to these parts, it is also possible to make use of plate exchangers, hav-
ing the characteristics required by the system currently in use. It is always necessary, in
any case, to install at least one system for micro-air bubble separation on the exchang-
er boiler delivery side. System filling water must always be treated as described above.

1. Define the diameter in the assembling point
2. Define flow in the assembling point (cu.m/h)
3. See the table to define the suitable model
circulating pump recommendations
Before switching on the boiler,
make sure that the circulating pump is
not blocked
due to inactivity: in the middle of the cap there is a hole (should
there be a cap, remove it) that gives access to the rotor shaft;
push and turn
it using a suitable tool
, usually a "Phillips" screwdriver.
filling the Water circuit
Once all system connections have been made, the circuit can be filled. For perfect boiler
filling, this operation should be carried out with extreme care, strictly following these steps:
- open radiator air purging valves;
- open heating system filling valve, and wait for all the air to be bled out of the radia-
tors;
- make sure that boiler automatic air purging valve works properly;
- close radiator valves as soon as water starts to come out;
