•  By pressing key 14 (Fig. 8.3) confirmation 

of the inserted value is obtained.

•  Press keys 17 or 18 (Fig. 8.3) to exit with-

out changing the value.

•  Exiting the “programming mode” is au-

tomatic,  after  15  minutes,  or  by  cutting 
power.

•  Calibrate the gas valve according to the 

instructions given in the Service manual, 
section Gas valve - Adjustment.

•  Reposition the controls panel and re-

mount the front panel of the body.

•  Apply the label indicating the gas nature 

and  pressure  value  for  which  the  appli-
ance is regulated. The self adhesive label 
is contained in the transformation kit.
