■INDEX
These instructions are intended for qualified heating engineers trained by ACV.
BG 2000-S burners are preset at the factory for natural gas.
ACV reserves the right to change the technical specifications and components of its products without prior notice.

■OPERATION
The BG 2000-S burner is fitted with a gas valve – venturi assembly, an electronic controller, a fan, a
flame holder and lighting and ionisation electrodes.
◆CONTROLLINGTHE AIR – GAS MIXTURE (illustration D)
As the fan sucks in air through the venturi, a drop in pressure (P1) is produced in the neck of the venturi.The
gas valve regulator then reacts to maintain a pressure differential equal to the offset value between the
pressure at the gas valve outlet (P2) and atmospheric pressure (P3): P2 – P3 = offset
If the air flow decreases, P1 increases;the same occurs for P2; P2 is then >P3;the regulator R is moved higher
to make P2 – offset = P3; pressure P4 falls and the valve C is turned down: the gas flow decreases.
By careful adjustment of the offset, an air – gas pressure ratio of 1 is obtained, regardless of the fan speed.
The pressure differential between the venturi neck and the gas valve outlet then causes gas to be sucked
through the venturi.
The gas flow adjustment screw can be used to adjust the quantity of gas injected for a given air flow, which will
set the %CO2 in the flue gas. A given output can then be set simply by adjusting the speed of rotation of the
fan and the % CO2 to preset values.
◆LIGHTING AND FLAME CONTROL
The S 4565 AD 2080 control unit performs the tasks of lighting the burner by producing a spark at the ignition
electrode, and maintaining the flame when the gas valve is opened by measuring the ionisation current.
The lighting sequence is shown in the diagram below:
When the boiler thermostat detects a demand for heat, the fan starts; after 15 seconds of preliminary flushing,
the gas valve is opened and simultaneously a spark is produced. If an ionisation current is detected in the first
5 seconds, combustion occurs normally until the end of the demand. If not, the gas valve is closed and the fan
stopped, the burner being in safety mode. It must then be reset manually before lighting is attempted again.

◆BURBER TUBE GAS (illustrations E / F / G)
The air-gas mixture leaving the gas valve - venturi assembly is forced into the burner tube gas and combustion
spreads evenly around the burner.
BG 2000-S burners are fitted with three different types of flame holder: two are made of stainless steel
(illustration E) for outputs less than 60 kW, the others (illustrations F / G) receive metal fibre (NIT) which distributes
the flame better. It also gives longer life and considerably lower pollution emissions.

■FITTING THE BURNER (illustrations L / M)
1. Remove the burner chamber plate.
2. Fit the BG 2000-S burner.
3. Insert the burner connector in the boiler socket.
4. Connect the gas to the burner, vent the air and test for gas leaks.
5. Start up the boiler.
■SETTINGS
Note:
•The offset value is set at the factory.
•The burner can only be fitted to one of the boilers in the table above.
•The CO2value given in the table above is valid only for natural gas; for propane, refer to the propane
conversion brochure. (code: 662Y0100)
■SETTING PROCEDURE IN CASE OF REPLACEMENT
◆FAN ROTATION SPEED
•Remove the green protective disk (1, illustration N) on the front of the fan.
•Remove the cover protecting the fan blades. (illustration P)
•Using a stroboscope (or any other suitable instrument) measure the rotation speed of the fan attached to the
motor shaft (3, illustration Q);adjust the fan speed to the value given in the setting parameter table by turning
the potentiometer screw (2, illustration O) (anticlockwise to reduce speed, clockwise to increase speed), after
the adjustment to replace the protection.
◆GAS FLOW RATE (illustration R)
•Measure burner combustion using an electronic flue gas analyser.
•Adjust the % CO2to the value given in the setting parameter table by turning the gas flow adjustment screw
(1, illustration R):anticlockwise for increased flow (rise in %CO2), clockwise for decreased flow (tall in % CO2).
