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 entire phase of "Self-calibrating procedure" described
in the specific section.
If the
gas valve
and/or the
ignition/detection electrode
, and/or the
burner
, and/or the
fan
are replaced, the user must still carry out
the entire phase of "Self-calibrating procedure" described in
the specific section.
