The gas coming from the supply line, passes through the filter and the valves group provided with stabiliser. This one forces the pres-
sure in the utilisation limits. The actuators proportionally move the air damper and the gas butterfly valve, microprocess-controlled in
order to optimise the gas flue values, as to get an efficient combustion. The combustion head positioning determines the burner’s
output. 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.
They can be provided in progressive or fully-modulating version.
