3.7 Checking combustion efficiency
3.7.1 Flue cleaning function
• The boiler features a flue cleaning function which must be used to measure combustion efficiency during operation and to adjust the
burner.
• To activate the flue cleaning function, press and hold the buttons - DHW and RESET simultaneously for 5 seconds. The flow temperature
and the symbol are shown on the LCD.
• When the flue cleaning function is activated with the boiler in WINTER or SUMMER mode, the boiler performs the ignition sequence and
then operates at a fixed power output predetermined by the parameter P7 (maximum CH output).
• To exit the flue cleaning mode, press RESET or wait 15 minutes.
3.7.2 Measurement procedure
The boiler is equipped with a tower allowing for air intake/flue gas venting pipe connection (see Fig. 14 Plugs position and Fig. 15 Hole
position).
The tower is designed with two pre-arranged openings directly accessing air and flue gas ducts (see Fig. 15 Hole position).
Remove caps A and B from the pre-arranged openings on the tower, before starting combustion checking procedure (see. Fig. 14 Plugs
position).
In order to verify combustion efficiency the following measurements must be implemented:
• assess combustion air from opening 1 (see Fig. 15 Hole position).
• assess flue gas temperature and CO2 from opening 2 (see Fig. 15 Hole position).
• Allow boiler to reach working temperature before taking any measurement.
