Maintenance
Flame sensor
Clean the glass cover from any dust that may have accumulated.
To remove the sensor 1)(Fig. 37) pull it outwards with force; it is
inserted only by pressure.
Flame inspection window
Clean the viewing port as required (Fig. 38).
Possible pump and/or coupling replacement
Carry out the fitting following the instructions in the Fig. 39.
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 paragraph “LED lamps: burner operating status” on
page 33.
Check Mode
With burner flame on:
 hold the reset button on the flame control pressed for at
least 3 sec.;
 the button colour will change from green to yellow;
 each operating status signalling LED will be compared to
20% of the maximum brightness;
 press the reset button again (<0.5sec) to reset the standard
operation of the signalling LEDs.
Combustion
Carry out an analysis of the combustion flue gases. Significant
differences with respect to the previous measurements indicate
the points where more care should be exercised during
maintenance.
If the combustion values measured before starting maintenance
do not comply with applicable Standards or do not indicate
efficient combustion, consult the table below or contact our
Technical Support Service to implement the necessary
adjustments.
