FIRING RATES (A)
The RS 190 model burner can work in two way:
one-stage and two-stage.
MAXIMUM OUTPUT
must be selected in area
A.
MINIMUM OUTPUT
must not be lower than the
minimum limit shown in the diagram.
RS 190
= 470 kW
Important
The FIRING RATE area values have
been obtained considering a surround-
ing temperature of 20 °C, and an at-
mospheric pressure of 1013 mbar
(approx. 0 m above sea level) and with
the combustion head adjusted as
shown on page 7.
TEST BOILER (B)
The firing rates were set in relation to special
test boilers, according to EN 676 regulations.
Figure (B) indicates the diameter and length of
the test combustion chamber.
Example:
Output 756 kW:
diameter = 60 cm; length = 2 m.
COMMERCIAL BOILERS
The burner/boiler combination does not pose
any problems if the boiler is CE type-approved
and its combustion chamber dimensions are
similar to those indicated in diagram (B).
If the burner must be combined with a commer-
cial boiler that has not been CE type-approved
and/or its combustion chamber dimensions are
clearly smaller than those indicated in diagram
(B), consult the manufacturer.
