FIRING RATES (A)
The burner output must be selected within the
area of the adjacent diagrams.
Attention
the FIRING RATE value range has been
obtained considering an ambient temperature of
20 °C, and an atmospheric pressure of
1013 mbar (approx. 0 m a.s.l.) and with the
combustion head adjusted as shown on page 9.
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 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.
