NOTE:
The performance curve is a diagram that represents the burner performance in the type approval phase or in the laboratory tests, but does not
represent the regulation range of the machine. On this diagram the maximum output point is usually reached by adjsuting the combustion head to its
“MAX” position (see paragraph “Adjusting the combustion head”); the minimum output point is reached setting the combustion head to its “MIN” position.
During the first ignition, the combustion head is set in order to find a compromise between the burner output and the generator specifications, that is why
the minimum output may be different from the Performance curve minimum

WARNING: the diagrams refers to natural gas. For different type of fuel please refer to the paragraph “Fuel” at
the beginning of this chapter.
The values in the diagrams refer to
natural gas
with a calorific value of 8125 kcal/Stm
3
(15°C, 1013 mbar) and a density of
0.714 kg/Stm
3
.
The values in the diagrams refer to
GPL
with a calorific value of 22300 kcal/Stm
3
(15°C, 1013 mbar) and a density of 2.14 kg/
Stm
3
. When the calorific value and the density change, the pressure values should be adjusted accordingly.
