Operating range
Fig. 1 X = Thermal power Y = Pression in the combustion chamber
The firing rates has been obtained based on test boilers in accordance with EN267 standards and are indicative of matching the
burner to the boiler.
For the correct operation of the burner, combustion chamber dimensions must be in accordance with current regulation. In case
of non-compliance, contact the manufacturer.
