Technical description of the burner
3.9.1 Commercial boilers
The burners are suitable for operation on either flame-inversion
boilers or boilers with combustion chambers featuring flow from
the base (three flue passes) on which the best results are ob-
tained in terms of low NOx emissions.
The burner-boiler match is assured where the boiler is EC type-
approved; for boilers and furnaces with combustion chambers
featuring dimensions differing considerably from those given in
the diagram, it is advisable to perform preliminary tests.

The maximum depth of the boiler door is referred to dimension
“I” (Fig. 1 on page 8).
