Technical description of the burner
4.3 Technical data
Tab. B
(1)
Reference conditions: Room temperature 20°C - Gas temperature 15°C - Barometric pressure 1013 mbar - Altitude 0 m a.s.l.
(2)
Pressure at the test point of the pressure switch 5)(Fig. 5) with zero pressure in the combustion chamber and at 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.
