GENERAL FEATURES
Burners of this series are provided with a removable cover made of ABS, a heat and crash proof plastic material. The design of the shi-
fitng flange assures an efficient tightness and room saving. All the mechanical components are mounted on a removable plate that
makes routine maintenance operation easier. The combustion head position can be easily adjusted by means of a indexed screw and
the peculiar air intake lower the noise levels.

10 Gas valves group
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 (5) moves proportionally
the air damper: it uses an adjusting cam with variable shape. This one allows the optimisation of the gas flue values, as to get an effi-
cient combustion. The combustion head positioning determines the burner output. 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.
