Tab. B
(1)
Reference conditions: Ambient temperature 20°C - Gas temperature 15°C - Barometric pressure 1,013 mbar - Altitude 0 m a.s.l.
(2)
Input gas pressure 8)(Fig. 3) with zero pressure in combustion chamber and at maximum burner output.
(3)
Sound pressure measured in manufacturer's combustion laboratory, with burner operating on test boiler, at maximum, average and minimum mod-
ulation output. The sound power is measured with the “Free Field” method, as per EN 15036, and according to an accurate “Accuracy: Category 3”
measurement, as described in EN ISO 3746.
