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 OIL VALVE
5 - NOZZLE
6 - GAS PRESSURE SWITCH
7 - SAFETY GAS VALVE
8 - GAS VALVE
Min gas pressure switch
The gas pressure switch has the function to check that the gas pressure before the gas
valve does have the minimum pressure to make the burner running correctly.
Unscrew off and remove cover M.
- Set knob N to a value equal to 60% of gas nominal feed pressure (i.e. for natural gas
nom. pressure = 20 mbar, set knob to a value of 12 mbar; for LPG nom. pressure of
G30/G31- 30/37 mbar, set knob to a value of 18 mbar). Screw up cover M.
Air pressure switch calibration
The air pressure switch is provided for monitoring the pressure of the
combustion air fan. Unscrew screws A and B and remove cover C.
• Adjust the combustion with air pressure switch (APS) set at minimum.
• Start to obstruct the air inlet with a paper paying attention to O2 and CO values red
on the analyzer.
• Progressively increase air inlet obstruction till the CO valve is slightly more than 1000
ppm. Stop obstruction in this position.
• Increase APS setting up to burner lock out.
• Now the APS is set to avoid CO production during the combustion.
• Remove air obstruction and fit again APS cover C.
