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.
