(1) Reference conditions: Ambient temperature 20°C - Barometric pressure 1000 mbar - Altitude 100 m a.s.l.
(2) 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.
