(1)
Reference conditions: Ambient 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 (Fig. 26 on page 26) 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 output. The sound
power is measured using the "Free Field" method, required by EN 15036 standard, and according to an “Accuracy: Category 3” measurement, as
described in EN ISO 3746.
