TECHNICAL DATA
(1)
Reference conditions: Room temperature 20°C - Gas temperature 15°C - Barometric pressure 1013 mbar - Altitude 0m above sea level.
(2)
Socket pressure 7)(A)p.4 with zero pressure in the combustion chamber.
(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.
