Input gas pressure 8)(Fig. 2) with zero pressure in combustion chamber and at maximum burner output.
(3)
Sound pressure measured in manufacturer's combustion lab, with burner operating on test boiler, at maximum, average and minimum modulation
output. The sound power is measured with the “Free Field” method, as per EN 15036, and according to an accurate “Accuracy: Category 3” meas-
urement, as described in EN ISO 3746.
