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 (Fig. 3), consult the
manufacturer.
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.

Commercial boiler

The burner RLS 190/M MZ is suitable for operating on boilers
with combustion chamber with bottom outflow (three passes), on
which the best NO emissions are obtained.
