Reference conditions: ambient temperature 68 °F (20°C) - Barometric pressure 394" WC - Altitude 329 ft.
(1)
Pressure at test point 20)(Fig. 3 at page 11) with zero pressure in the combustion chamber and maximum burner output.
(2)
Sound pressure measured in manufacturer's combustion laboratory, with burner operating on test boiler and at maximum rated output.
(3)
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
Equivalent Btu values based on 1 USGPH = 140,000 Btu/hr.
