Gas operation:
the gas coming from the supply line, passes through the valves group provided with filter and stabiliser. This one for-
ces the pressure in the utilisation limits. The electric actuator , that moves proportionally the air damper and the gas butterfly valve,
uses an adjusting cam with variable shape. This one allows the optimisation of the gas flue values, as to get an efficient combustion.
The combustion head positioning determines the burner’s output. The combustion head determines the energetic quality and the geo-
metry of the flame. Fuel and comburent are routed into separated ways as far as the zone of flame generation (combustion chamber).
The control panel , placed on the burner’s front side, shows each operating stage.
