CALCULATION OF WORKING OUTPUT OF THE BURNER
To calculate the burner's working output, in kW, proceed as follows:
- Check at the meter the quantity of supplied litres and the duration,
in seconds, of the reading, then calculate the burner's output through
the following formula:
1 - PUMP
2 - SAFETY OIL VALVE
3 - OIL VALVE
4 - RETURN VALVE
5 - NOZZLE
6 - GAS PRESSURE SWITCH
7 - SAFETY GAS VALVE
8 - GAS VALVE
ADJUSTMENT OF GAS MINIMUM PRESSURE SWITCH
Unscrew off and remove cover M. - Set regulator N to a value equal to 60% of gas nominal feed pres-
sure (i.e. for nat. gas nom. pressure = 20 mbar, set regulator to a value of 12 mbar; for L.P.G. nom.
pressure of G30/G31- 30/37 mbar, set regulator to a value of 18 mbar).Screw up cover M
ADJUSTMENT OF THE AIR PRESSURE SWITCH
Unscrew screws A and B and remove cover C.- Set the pressure switch to the minimum by tur-
ning regulator D to position 1.
- Start the burner and keep in low flame running, while checking that combustion is correct.
Through a small cardboard, progressively obstruct the air intake until to obtain a CO2 increa-
se of 0,5÷0,8% or else, if a pressure gauge is available, connected to pressure port E, until rea-
ching a pressure drop of 1 mbar (10 mm of W.G.). - Slowly increase the adjustment value of
the air pressure switch until to have the burner lockout. Remove the obstruction from the air
intake, screw on the cover C and start the burner by pressing the control box rearm button.
Note: The pressure measured at pressure port E must be within the limits of the pressure
switch working range. If not, loose the locking nut of screw F and gradually turn the same:
clockwise to reduce the pressure; counterclockwise to increase. At the end tighten the locking
nut.
