To enter "Parameter setting and display"refer to the indications
provided in the specific section.
Once the parameters in the table have been set, you must carry
out the "Automatic calibration procedure".
If the
gas valve and/or the ignition/detection electrode and/or the
fan are replaced, the user must still carry out the entire phase
of "Automatic calibration procedure" described in the specific
section.
