Reference conditions:
Temperature: 20°C - Pressure: 1013,5 mbar - Altitude: 0 m a.s.l. - Noise measured at a distance of 1 meter. 
Sound pressure measured in manufacturer’s combustion laboratory, with burner operating on test boiler and at maximum 
rated output. The sound power is measured with the “Free Field” method, as per EN 15036, and according to an “Accuracy: 
Category 3” measuring accuracy, as set out in EN ISO 3746.
