Fully-modulating burners
To adjust the fully-modulating burners, use the CMF switch on the burner control panel (see next picture), instead of the TAB thermo-
stat as described on the previous paragraphs about the progressive burners. Go on adjusting the burner as described before, paying
attention to use the CMF switch intead of TAB.
The CMF position sets the oprating stages: to drive the burner to the high-flame stage, set CMF=1; to drive it to the low-flame stage, set
CMF=2.
To move the adjusting cam set CMF=1 or 2 and then CMF=0.
EVL air valve for gun cleaning
After the flame is off, an automatic system provides the compressed air to clean the gun.
