ADJUSTING THE MINIMUM CAPACITY OF THE BURNER – AIR and GAS
Position the selector placed on the control panel on position 2 and proceed as follows:
Adjust the minimum gas flow rate using a suitable wrench, turn the butterfly valve until you reach the correct gas flow,
as established by analyzing the combustion process.
Position the selector, situated on the control panel, on position 1 and proceed as follows:
Adjusting the maximum gas flow rate (see figure on solenoid valve adjustments) or adjust the gas pressure in the gover-
nor.
Adjusting the maximum air flow rate (see figure, detail 2). Loosen the nut holding the air damper transmission rod;
The correct air flow as established by analyzing the combustion process.
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 gas 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.
WARNING: In order to have a correct combustion and thermal output adjustments, these must be carried out together
with a combustion analysis, to be executed through suitable devices, taking care that the values are the correct ones and
are in accordance with the local safety regulations. The adjustments must be carried out by qualified and skilled techni-
cians authorised by Ecoflam Bruciatori S.p.A.
