TEST BOILER
The firing rate has been defined according to EN 676 standard.
COMMERCIAL BOILERS
The burner-boiler matching is assured if the boiler conforms to EN 303 and the combustion chamber
dimensions are similar to those shown in the diagram EN 676.
For applications where the boiler does not conform to EN 303, or where the combustion chamber is much
smaller than the dimensions given in EN 676, please consult the manufacturers.
CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT
To obtain the maximum output, a gas head pressure of 6.9 mbar is measured (M2, see chapter 3.3, page 4) with
the combustion chamber at 0 mbar using gas G20 with a net heat value of 10 kWh/Nm
