GENERAL FEATURES
These burners are characterised by high performaces and width in the performance curves, when the pressure in the combustion
chamber is high. They are also characterised for other important functional features: there are plugs which can be easily connected to
the boiler and to the detecting probes, a pressure plug in the combustion chamber, all mechanical components are mounted on a plate
which can be quickly taken off for maintenance. The head is adjustable through a graduated screw. The gas train can be mounted
either on the right side or on the left side.

The gas coming from the supply line, passes through the valves group provided with filter and stabiliser. This one forces the pressure in
the utilisation limits. In the double-stage , progressive and fully- modulating burners, the electric servocontrol (7), that moves proportio-
nally 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
(1) determines the energetic quality and the geometry of the flame. Fuel and comburent are routed into separated ways as far as the
zone of flame generation (combustion chamber). The air (comburent) and fuel (gas, gas oil, heavy oil) are forced into the combustion
chamber.
The control panel, placed on the burner’s front side, shows each operating stage.
