RS 190

Important

The FIRING RATE value range has been
obtained considering an ambient temperature of
20 °C, and an atmospheric pressure of 1000
mbar (approx. 100 m above sea level) and with
the combustion head adjusted as shown on
page 7.
D1262 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
D715
(B), consult the manufacturer.
