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.
