FIRING RATE
TEST BOILER
The firing rate has been defined according to EN 676 standard.
COMMERCIAL BOILERS
The burner-boiler matching is assured if the boiler is according to EN 303 and the combustion
chamber dimensions are similar to those shown in the diagram EN 676.
For applications where the boiler is not according to EN 303, or where the combustion chamber
dimensions differ from those shown in EN 676, please consult the manufacturers.
CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT
To obtain the maximum output, a gas head pressure of 4.6 mbar is measured with the combustion
chamber at 0 mbar using gas G20 with a net heat value of 10 kWh/m3 (8,570 kcal/m3).

ELECTRICAL CONNECTIONS
NOTES
The electrical wirings must be carried out in conformity with the regulations in force in the countries of
destination, and by qualified personnel.
Riello S.p.A. cannot accept any responsibility for modifications or connections other than those shown in
these diagrams.
Do not swap neutral and phase over, follow the diagram shown carefully and carry out a good earth
connection.
The cross section of the wires must be at least 1 mm2. (Unless requested otherwise by local standards and
legislation).

COMBUSTION HEAD ADJUSTMENT
In conformity with Efficiency Directive 92/42/EEC
the application of the burner on the boiler, adjust-
ment and testing must be carried out observing
the instruction manual of the boiler, including ver-
ification of the CO and CO2concentration in the
flue gases, their temperatures and the average
temperature of the water in the boiler.
Loose the screw (A), move the elbow (B) so that
the rear plan of the coupling (C) coincides with
the set point.
Tight the screw (A).
Example:
The burner is installed on a 40 kW
boiler with an efficiency of 90%, the
burner input is about 44 kW using
the diagram below, the combustion
set point is 3.
The diagram is to be used only for
initial settings, to improve air
pressure switch operation or
improve combustion, it may be
necessary to reduce this setting
(set point toward position 0).
It is advisable to set the burner according to the type of gas used and following the indications of
the table:
IONIZATION CURRENT
The minimum current required by the
control box is 5 µA.
The burner would normally have a
higher current value than this, but if a
check is required, open the connector
fitted in the red probe lead and insert a
microammeter as shown.
