Test boiler
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 boiler that has not been EC
approved and/or its combustion chamber dimensions are clearly
smaller than those indicated in the diagram, consult the
manufacturer.
3.8.1
Commercial boilers
The burner is suitable for operating on both flame inversion boil-
ers as well as on boilers with a combustion chamber with run-off
from the bottom (three flue passes) on which the best results for
low NO
emissions are obtained.

The maximum thickness of the boiler front door must not exceed
200 mm (see Fig. 4).
The coupling is ensured when the boiler is EC type-approved; for
boilers or ovens with combustion chambers of very different di-
mensions compared to those shown in the diagram of (Fig. 3)
preliminary checks are recommended.
