Centre is available for any further information.
FERROLI S.p.A. declines all liability for damage to persons and/or things deriving from tampering with
the appliance by non-authorised persons
3.1 Settings
Head and air damper adjustment
The adjustment of the head depends on the flow-rate of the
burner. The head is adjusted by rotating the adjustment screws
"B" clockwise or anticlockwise until the notch on rod "A" is n line
with the reference.
This modifies the position of the baffle in respect to the draught
tube, and as a consequence the flow of air.
To adjust the air flow-rate, use screw "C" after loosening nut "D".
At the end of adjustment tighten nut "D".
To limit the amount of dispersion from the stack when
the boiler is off, the burner is fitted with a gravity-closing
air damper that closes automatically when the burner
stops.
To perform a preliminary adjustment of head and air damper during installation (before commissioning
and consequently calibrating the appliance using instruments), use the graph below:

Adjusting pump pressure

The pressure of the pump is factory-set to 12 bars, for optimum operation, and normally should not be
modified. Nonetheless, if under specific circumstances a different pressure needs to be set, once having
attached the pressure gauge and ignited the burner, use the adjustment screws "6" indicated in fig. 4.
In any case, it is recommended to keep within the range 10 - 14 bars.
