13.2.1 Emissioncheck
In order to be able to check on the boiler’s emission during its years of operation, it is
recommended to measure the maximum air displacement of the boiler on commissioning.
This value may be different for each boiler type.
This measuring is only worthwhile if the value is known on commissioning.
The following tasks have to be carried out to enable measuring this value:
- Press down the arrow buttons simultaneously for 2 seconds.
The screen turns green;
- Press the right arrow button until you see Service chapter.;
- Press OK;
- Press the right arrow button until Airush is displayed;
- Press OK;
The screen displays Airush off;

- Connect the hose of the digital pressure meter to the top test nipple of the gas unit

- Press on the + button until the maximum value (100%).
The ventilator will start running up to its max. revolutions per minute RPM (burner
stays on)
- Measure the under-pressure and record the value.
During the next boiler check, the under-pressure value may have decreased by 20%
max. compared to the value on commissioning. If this value has decreased less than
20% the boiler does not require any maintenance.

This ends the procedure for burner A.
