TECHNICAL DATA
(1)
Reference conditions: Ambient temperature 20°C - Barometric pressure 1000 mbar - Altitude 100 m a.s.l.
(2)
Pressure at pressure switch test point 20)(A)p.12 with zero pressure in the combustion chamber and maximum burner output.
(3)
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.
