1. Fill the system with clean tap water (advised water pressure is
between 1 and 2 bar).
2. Check the tightness of the water connections.
3. Turn the boiler on.
After the power is switched on, the boiler always runs
through an automatic venting programme lasting approx.
4 minutes (During filling, air can escape from the system
via the automatic air vent). If necessary, top up the water
level in the heating system (recommended hydraulic
pressure between 1 and 2 bar).
CAUTION
When venting, ensure that no water enters or makes
contact with the casing and electrical parts of the boiler.
