Note1:
All gas flow rates are referred to Stm
(net calorific value H
Note2:
Maximum gas pressure= 360 mbar (with Dungs MBDLE)
Maximum gas pressure= 500 mbar (with Siemens VGD or Dungs MultiBloc MBE)
Minimum gas pressure= see gas curves.
Warning:
Burners are suitable only for indoor operation with a maximum relative humidity of 80%
NOTE ON THE BURNER WORKING SERVICE: for safety reasons, one controlled shutdown must be performed every 24 hours of
continuous operation.NOTE: Choosing the nozzle for light oil, consider Hi equal to 10200 kcal/kg.
