Pressure at test point 18)(Fig. 5, 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.
