INFORMATION ABOUT THE INSTRUCTION MANUAL
INTRODUCTION
The instruction manual supplied with the burner:
- is an integral and essential part of the product and must not be sepa-
rated from it; it must therefore be kept carefully for any necessary
consultation and must accompany the burner even if it is transferred
to another owner or user, or to another system. If the manual is lost
or damaged, another copy must be requested from the Technical
Assistance Service of the area;
- is designed for use by qualified personnel;
- offers important indications and instructions relating to the installation
safety, start-up, use and maintenance of the burner.
DELIVERY OF THE SYSTEM AND THE INSTRUCTION MAN-
UAL
When the system is delivered, it is important that:
- The instruction manual is supplied to the user by the system manu-
facturer, with the recommendation to keep it in the room where the
heat generator is to be installed.
- The instruction manual shows:
- the serial number of the burner;
- the address and telephone number of the nearest Assistance
Centre;
- The system supplier carefully informs the user about:
- the use of the system,
- any further tests that may be necessary before the system is
started up,
- maintenance and the need to have the system checked at least
once a year by the manufacturer or another specialised techni-
cian.
To ensure a periodic check, recommends the drawing up
of a Maintenance Contract.

TEST BOILER
The working field has been defined according to EN 676 standard.
COMMERCIAL BOILERS
The burner-boiler matching is assured if the boiler conforms to EN 303 and the combustion chamber dimensions
are similar to those shown in the diagram EN 676. For applications where the boiler does not conform to EN 303,
or where the combustion chamber is much smaller than the dimensions given in EN 676, please consult the
manufacturers.
CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT
To obtain the maximum output, a gas head pressure of 5.8 mbar is measured (M2, see chapter 3.3, page 4) with
the combustion chamber at 0 mbar using gas G20 with a net heat value of 10 kWh/Nm3(8,570 kcal/Nm3).
3. INSTALLATION
THE BURNER MUST BE INSTALLED IN CONFORMITY WITH LEGISLATION AND LOCAL STANDARDS.

3.4 ELECTRICAL WIRING
ATTENTION:
³Do not swap neutral and phase over, follow the diagram shown carefully and carry out a good earth connection.
³The section of the conductors must be at least 1mm. (Unless requested otherwise by local standards and legislation).
³The electrical wiring carried out by the installer must be in compliance with the rules in force in the country.
³Verify that the burner stops by operating the boiler control thermostats and that the burner locks out by separating
the red ionisation probe lead connector.
NOTES
The burners have been type-approved for intermittent operation. This means they must stop at least once every 24 hours in
order to allow the electrical control box to check its efficiency on start-up. The boiler limit thermostat (TL) normally ensures
the burner halts. If this does not happen a time switch halting the burner at least once every 24 hours must be applied in se-
ries to limit thermostat (TL).

4. WORKING
4.1 COMBUSTION ADJUSTMENT
In conformity with Efficiency Directive 92/42/EEC the application
of the burner on the boiler, adjustment and testing must be car-
ried out observing the instruction manual of the boiler, including
verification of the CO and CO2concentration in the flue gases,
their temperatures and the average temperature of the water in
the boiler.
To suit the required appliance output, choose the proper set-
ting of the combustion head, and the air damper opening.
4.2 COMBUSTION HEAD SETTING
Loose the screw (A), move the elbow (B) so that the rear plate
of the coupling (C) coincides with the set point.
Tighten the screw (A).
Example:
The burner is installed on a 81 kW boiler
with an efficiency of 90%, the burner
input is about 90 kW using the diagram,
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).

4.3 AIR DAMPER SETTING
The regulation of the air-rate is made by adjusting the air damper (1), after
loosing the screws (2).
When the optimal regulation is reached, screw tight the screws (2).
4.4 COMBUSTION CHECK
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 necessary for the control box operation is 3 μA.
The burner normally supplies a higher current value, so that no check is needed. However, if you want to measure
the ionization current, you must open the connector fitted to the red wire and insert a microammeter.
4.5 AIR PRESSURE SWITCH
The air pressure switch is set after all other adjustments have been made. Begin with the switch at the lowest
setting. With the burner working at the minimum output, adjust the dial clockwise, increasing its value until
the burner shuts down. Now reduce the value by one set point, turning the dial anti-clockwise.
Check for reliable burner operation, if the burner shuts down, reduce the value by a half set point.
Attention:
To comply with the EN 676 standard, the air pressure switch must operate when the CO value exceeds 1%
(10,000 ppm). To check this, insert a combustion analyser in the flue, slowly reduce the burner air setting and ver-
ify that the burner shuts down by the action of the air pressure switch before the CO value exceeds 1%.
