9.6 Prior to Commissioning:

• Check system pressure is correct;
• Power boiler;
• Open gas tap (positioned under boiler);
• Select required heating mode. See section 10.4 Operating Modes.

indicating "de-aeration" function is active. This function lasts 10 minutes.
3.
Boiler will turn on after deaeration function is complete. Display will show code "000" alternating with % of ignition power and
temperature value (°F / °C).
• During this gas recognition function phase which lasts about 7 minutes, type of gas being used is analyzed.
• During this function, assure maximum heat exchange to heating or DHW system (domestic hot water demand) by having all
heating zones open or all domestic hot water taps open, in order to prevent boiler from switching off due to overheating.
• If boiler operates on Gas A (Natural Gas), display shows NG (Natural Gas) for about 10 seconds. Boiler is now ready for
