Firing rates
The MAXIMUM OUTPUT is chosen from within the continuous
diagram area (Fig. 3).
The MINIMUM OUTPUT must not be lower than the minimum
limit of the diagram:
RLS 1600/E C11 = 3065 kW
RLS 2000/E C11 = 4000 kW

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. 4).
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 manufac-
turer. The firing rates were set in relation to special test boilers,
according to EN 676 regulations.

Thermal power – kW
The firing rate value (Fig. 3) has been obtained
considering an ambient temperature of 20 °C, an
atmospheric pressure of 1,013 mbar (approx. 0 m
a.s.l.), and with the combustion head adjusted as

Output 7000 kW - diameter 120 cm - length 6 m
MODULATING RATIO
The modulating ratio, obtained in the test boilers, according to
standard (EN 676 for gas, EN 267 for light oil), is of 4:1.
