light oil flow increases, while unscrewing it, it decrease.
Adjustment the minimum air flow rate (see figure, detail 1):
- loosen the Allen screw on the air damper clamp;
- turn the air damper until you reach the correct air flow, as established by analyzing
the combustion process.
- tighten the Allen screw in place once again.
Position the selector, situated on the control panel, on position 1 and proceed as follows:
Adjustment the maximum light oil flow rate (see figure, Nozzle diagram):
- using a suitable allen key, change the position of the cam guide blade ; screwing the cam in, the light oil flow
increases, while unscrewing it, it decrease.
Adjustment the maximum air flow rate (see figure, detail 2):
- loosen the nut holding the air damper transmission rod;
Using the selector, start the servomotor (closing or opening) and position on 0 to stop the stroke; the adjustment is
made as outlined below. Repeat the operation for the other cam points.
Adjustment the intermediate light oil flow rates (see figure, detail 3):
- using a suitable Allen wrench, change the position of the cam guide blade; if you screw it down, the flow rate is
reduced; if you unscrew it, the flow rate increases.
The firing head position adjustment is made in order to obtain the best combustion efficiency. When used with mini-
mum outputs the firing head is adjusted in rear position. With high output, the firing head is adjusted in forward posi-
tion. Adjustment: - Loosen screw A through a suitable Allen key. - By a screwdriver act on the hex. head screw B until
is reached the desired position. - Tighten screw A

All burners are factory tested at 400V - 50Hz 3-phase for motors, and 230V - 50Hz single phase with neutral for auxi-
liary equipments. Should it be necessary to power the burner with 230V - 50Hz, modify the connections on motor and
the terminal board as shown in the picture. Protect the burner supply line with suitable fuses and/or other safety devices
as required by the local regulations on the matter.
