If replacing the 

electronic board

, the user MUST set the 

parameters as indicated in the table.

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 "
