FIRING RATES (A)
During operation, burner output varies between:
• a MAXIMUM OUTPUT, selected within area A,
• and a MINIMUM OUTPUT, which must not be
lower than the minimum limit in the diagram:
RS 34 MZ = 70 kW
RS 44 MZ = 100 kW
Attention
The FIRING RATE values have been obtained
considering an ambient temperature of 20 °C, a
barometric pressure of 1013 mbar (approx.0m
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 350 Mcal/h:
diameter = 50 cm; length = 1.5 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 approved and/or
its combustion chamber dimensions are clearly
smaller than those indicated in diagram (B),
consult the manufacturer.
In addition, for inversion boilers you are advised
to check the length of the combustion head, as
indicated by the boiler manufacturer.
