Firing rate (G20 - G30 - G31)

The burner output is chosen from within the diagram area
(Fig. 2).
In addition, burner can be applied for operation with the combus-
tion chamber featuring negative pressure (up to - 2 mbar) accord-
ing to the approval terms provided for in standard EN 746-2 for
the whole unit complete with equipment.
4.3.1

Test boiler

The firing rate has been defined according to EN 676 standard.
4.3.2

Commercial boilers

The burner-heat generator team does not pose problems provid-
ed the generator and size of the combustion chamber are similar
to those provided for in standard EN 676.
If, on the other hand, the burner is teamed with a commercially-
available heat generator and the combustion chamber is much
smaller than the size indicated in standard EN 676, you should
consult the manufacturers.
