Technical description of the burner
5.6 Firing rate (EN 267)
The burner output is chosen from within the diagram area (Fig. 3).
Tab. E
5.6.1 Test boiler
The firing rate has been defined on test boilers according to EN
267 standard.
5.6.2 Commercial boilers
The burner-boiler combination does not pose any problems if it
conforms to EN 303 and the combustion chamber dimensions
are similar to those provided by EN 267.
For applications where the boiler does not conform to EN 303, or
where the combustion chamber is much smaller than the dimen-
sions given in EN 267, please consult the manufacturers.
WARNING
To ensure the burner works correctly, the start-up
should always occur within the relative firing rate,
as indicated in Tab. E.
