SELECTOR
MINIMUM CAPACITY ADJUSTMENT OF THE BURNER
Position the selector, situated on the control panel, on position 2 and proceed as follows:
Adjustment the minimum 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 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.
MAXIMUM CAPACITY ADJUSTMENT OF THE BURNER
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;
ADJUSTMENT THE INTERMEDIATE BURNER CAPACITIES
Using the selector, start the servomotor (closing or opening) and position on 0 to stop the stroke; the adjust-
ment 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.
