This series of burners represents, in terms of dimensions and output, the small-medium series of the new line IDEA standard Low NOx Class 2 (< 120 mg/kWh) with tangential ventilation. These burners are particular suitable to work on high efficiency boilers. The burner is designed to be aesthetic and functional giving at the same time prominence to innovative technologies.

Minimum inlet gas pressure (mbar) Minimum inlet gas pressure (mbar) Minimum inlet gas pressure (mbar) Minimum inlet gas pressure (mbar) Minimum inlet gas pressure (mbar) Attention: the graph shows the value of the gas output (kW) against the corresponding pressure without the combustion chamber back pressure. To know the minimum gas pressure at gas train, in order to get the gas output, it is necessary to add the boiler back pressure to the value read on the curve.
