Fill the system and vent it correctly in line with the details

in the chapter "Water treatment" to ensure the perfect

function of the condensing boiler (see page 30).

Before connecting the gas condensing boiler,

flush the heating system to remove residues

such as welding pearls, hemp, putty, etc. from

the pipework.

• The gas tap must be shut.

• Open the air vent valves.

• Open all heating circuits.

• Open all radiator or mixer valves.

• Slowly fill the entire heating system and boiler when

cold, for example via the BDF valve at the return, to

approx. 2 bar pressure.

Inhibitors are not permissible.

• Open the flow valves on the condensing boiler.

• Fill the heating system to 2 bar pressure. In operation,

the pressure gauge must indicate between 1.5 and

5.5 bar.

• Check the entire system for water leaks.

• Remove the siphon.

• Fill the siphon with water.

• Refit the siphon.

• Start the condensing boiler, set the heating water

selector to position "2" (pump running, illuminated

status indicator ring constantly green).

• Vent the heating circuit; for this, switch the gas

condensing boiler ON and OFF again several

times.

• Top up with water when the system pressure falls

substantially.

• Open the gas ball valve.

• Press the reset button.

Note:

In constant mode, the heating circuit is

automatically vented via the air vent valve

(accessory).

The condensate hose attached to the siphon

must not form a loop or roll up, otherwise the

operation might be impaired.
