Maintenance
Fan
Check to make sure that no dust has accumulated inside the fan
or on its impellers, as this condition will cause a reduction in the
air flow rate and provoke polluting combustion.
Boiler
Clean the boiler as indicated in its accompanying instructions in
order to maintain all the original combustion characteristics
intact, especially: the flue gas temperature and combustion
chamber pressure.
Flame presence check
Check the level of the flame detection signal with the “Check
Mode” function from the flame control: LEDs from 2 to 6 indicate
the flame signal level, respectively.
see “Description of LED lamps” on page 41

With burner flame on:

hold the reset button on the flame control pressed for at


the button colour will change from green to yellow;


20% of the maximum brightness;

press the reset button again (<0.5sec) to reset the standard
operation of the signalling LEDs.
