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.
CALCULATING THE BURNER CAPACITY
To calculate the burner's capacity in kW, proceed as follows: Check the gas flow rate (in liters) on
the counter and the time of the reading in seconds.
Proceed with the calculation using the following :
