Test boiler

The firing rates were obtained in special test boilers, according to
EN 676 standard.
In Fig. 3 you can see the diameter and length of the test
combustion chamber.
Example:
Output 407 kW (350 Mcal/h) - diameter 50 cm, length 1.5 m.

Commercial boilers

The burner/boiler combination does not pose any problems if the
boiler is EC approved and its combustion chamber dimensions
are similar to those indicated in the diagram (Fig. 3).
If the burner must be combined with a commercial boiler that has
not been EC approved (CE mark) and/or its combustion chamber
dimensions are clearly smaller than those indicated in diagram
(Fig. 3), consult the manufacturers.
In addition, for inversion boilers you are advised to check the
length of the combustion head, as indicated by the boiler
manufacturer.
