Flame presence check
Check the level of the flame detection signal with the “Check
mode” function from the flame control: the LEDs from 2 to 6
indicate the flame signal level, respectively. See “LED indicator
and special function” on page 31.
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.Boiler
Clean the boiler as indicated in its accompanying instructions in
order to maintain all the original combustion characteristics in-
tact, especially the flue gas temperature and combustion cham-
ber pressure.
Gas leaks
Make sure that there are no gas leaks on the pipes between the
gas meter and the burner.
Gas filter
Replace the gas filter when it is dirty.
Combustion
If the combustion values measured before starting maintenance
do not comply with applicable legislation or do not indicate effi-
cient combustion, consult the Tab. K or contact our Technical
Support Service to implement the necessary adjustments.
It is advisable to set the burner according to the type of gas used
and following the indications in Tab. K.
