Technical description of the burner
4.8 Firing rate
The burner output is chosen from within the diagram area (Fig. 3).
4.8.1 Commercial boilers
The burner-boiler combination poses no problems if the boiler
conforms to EN 303 and its combustion chamber dimensions are
similar to those provided in EN 267.
If, on the other hand, the burner is combined with a commercial
boiler that does not conform to EN 303, or where the combustion
chamber is much smaller than the dimensions set out in EN 267,
please contact the manufacturers.
4.8.2 Test boiler
The firing rate has been defined on test boilers according to EN
267 standard.
WARNING
To ensure the burner works correctly, start-ups
should always occur within the relative firing rate.
WARNING
The firing rate (Fig. 3) was obtained at an ambient
temperature of 20 °C, at a barometric pressure of
1013 mbar (about 0 m a.s.l.) and with the combus-
tion head regulated as indicated on page 19.
