6.6.2 Filling the siphon
1. Fill the siphon with water up to the mark using the condensate
collector.
Danger
The siphon must always be sufficiently filled with water. This
prevents flue gases from entering the room.
Warning
Put the sealing cap back on the condensate collector.
6.6.3 Filling the installation
1. Disconnect the boiler from the power supply.
2. Fill the central heating system with clean tap water.
Important
The recommended water pressure is between 1.5 bar and 2 bar.
3. Check the water-side connections for tightness.
4. Power up the boiler.
Important
DIEMATIC iSystem: If the water pressure is below 0.8 bar, the
symbol will flash (only if a hydraulic pressure sensor is
connected). If the water pressure is too low, top up the central
heating system.
IniControl: Check the water pressure that is shown on the
display (only if a hydraulic pressure sensor is connected). If the
water pressure is lower than 0.8 bar, top up the central heating
system.
