Firing rates

The burners can work in two ways: one stage and two stage.
MAXIMUM OUTPUT must be selected in area A (and B for model
RLS 130). In order to utilize also area B (RLS 130) it is necessary
to perform the calibration of the combustion head as explained on
page 16.
MINIMUM OUTPUT must not be lower than the minimum limit
shown in the diagram:
Model kW
RLS 70 232
RLS 100 349
RLS 130 465
The firing rate value (Fig. 3) has been obtained
considering an ambient temperature of 20 °C, an
atmospheric pressure of 1013 mbar (approx. 0 m
above sea level), and with the combustion head
WARNING
adjusted as shown on page 27.

Test boiler

The firing rates were set in relation to special test boilers, accord-
ing to EN 676 and EN 267 regulations.
Fig. 4 indicates the diameter and length of the test combustion
chamber.
Example:
output 650 Mcal/h: diameter 60 cm - length 2 m.

4.10.1 Commercial boilers

The burner/boiler combination does not pose any problems if the
boiler is CE type-approved and its combustion chamber dimen-
sions are similar to those indicated in diagram (Fig. 4).
If the burner must be combined with a commercial boiler that has
not been CE type-approved and/or its combustion chamber di-
mensions are clearly smaller than those indicated in diagram
(Fig. 4), consult the manufacturer.
