Position Of Electrodes-Baffle - Ferroli SUN Series Installation, Use And Maintenance Instructions

COMBUSTION HEAD AND AIR
DAMPER ADJUSTMENT (Fig. 8)
The combustion head is adjusted accord-
ing to burner flow rate. To adjust, rotate
the adjustment screw (B) clockwise or
anticlockwise until the notch on the rod
"A" coincides with the indicator.
This modifies the position of the deflec-
tor in relation to the draught tube and con-
sequently the passage of air.
The air flow rate is adjusted via screw "C".
When the burner shuts down, the air
damper closes automatically.
EXAMPLE OF COMBUSTION REGU-
LATION
The injector, pump pressure, combustion
head adjustment and air flow rate regula-
tion must be established according to the
flow rate required by the boiler, as indi-
cated in the following chart check com-
bustion.
