TEST BOILER
The working field has been defined according to DIN 4788 and EN 676 standards.
COMMERCIAL BOILERS
The burner-boiler matching is assured if the boiler is according to EN 303 and the comb ustion
chamber dimensions are similar to those shown in the diagram EN 676.
For applications where the boiler is not according to EN 303, or where the combustion chamber
dimensions differ from those shown in EN 676, please consult the manufacturers.

CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT

To obtain the maximum output, a gas head pressure of 6.8 mbar is measured with the combustion
chamber at 0 mbar using gas G20 with a net heat value of 10 kWh/m
