Operating principle

4.2.1

Air-gas adjustment

The air is drawn in by the fan and gas injected directly at the height of the venturi. The fan revolution speed is regulated
automatically by the electronic board based on the adjustment settings. The gas and air are mixed in the manifold. The gas/air
ratio ensures that the quantity of gas and air are adjusted correctly to always obtain optimal combustion. The gas/air mixture is
fed into the burner at the front of the exchanger. Here, the electric igniter triggers the mixture with a series of sparks that burn,
producing thermal energy.
