Guarantee
Installation and start-up must be carried out in accordance with correct practice by a qualified specialist. Current regulations, as well as the following instructions, must be complied with. Any failure, however minor, to observe these provisions shall absolve the manufacturer from any liability. Also see:
- guarantee certificate enclosed with burner,
- general terms of sale.
Safety
The burner is designed to be installed on a generator connected to exhaust pipes used for combustion products in working conditions. It should be used in an area where there is an adequate supply of combustion air and where polluted products can be properly evacuated. Flue size and design must be appropriate to the fuel, in accordance with current regulations and standards. The control and safety unit and cut-off devices used require a 230 VAC % 50 Hz
±1%
power supply.
In addition, the neutral conductor
must have the same electrical potential as the earth conductor.
Should this not be possible, the burner should be electrically supplied with an isolating transformer with the necessary safety devices (fuses and differential circuit breaker 30 mA). In order that the burner operates
correctly, please respect the polarity of the conductors when connecting the 7P connector.
The burner must be able to be isolated from the system via an all pole switch complying with the standards in force. Operating staff should always act with extreme caution and especially avoid direct contact with areas that are not heat-insulated and electrical circuits. Avoid splashing water on the electrical components of the burner. In the event of flood, fire, fuel leakage or abnormal operation (strange smells, noises, etc.), switch off the burner, turn off the power and fuel supplies and call in a qualified specialist. It is essential that all furnaces and accessories, waste gas ducts and connection pipes are serviced, cleaned and swept once a year and before burner start-up. See the applicable regulations in force.

Settings check Combustion components Secondary air
Secondary air (Y dimension)
It is the air flow admitted between the different diameters of the baffle and the blast tube. On delivery, dimension Y is set to 453 for KN and 753 for KL. However depending on:
- firing quality (shock, vibration, judder, delay),
- the cleanliness of the gas flow combustion,
this value can be changed.
Setting This is done when the burner is stopped by disassembling the combustion elements following the process described in the previous chapter. By increasing dimension Y, the secondary air is reduced and the CO
2
increases and vice versa.
• Unscrew the two screws from the baffle support.
• Slide the baffle support in the desired direction.
• Measure the dimension Y; tighten the two screws again.
• Adjust the diffusers according to the type of head and the gas used as per the plan opposite.

Description and settings Gas valve/leak testing device
Leak testing device VPS 504 S02
How it works: Before each activation of the burner the test device is used to test the leak tightness between the safety valves and the principle valves by raising the distribution pressure. Electrically the leak tightness test device is connected in series between the thermostatic circuit and the burner’s control and safety unit.
Setup: Directly onto the valve.
Program cycle: When the burner is switched off the safety valves and principle valves are closed. When the thermostat is closed, the leak tightness test device is switched on and the booster increases the distribution pressure by 20 mbar. After running for a maximum of 30 seconds:
- The leak test is validated; the yellow
light comes on, a voltage is released to power the burner control and safety unit, which begins its program.
- The leak test is not validated; the red
light comes on, power is not supplied to the control and safety unit.
- Manual intervention is required to
relaunch a test cycle. If the problem persists the valve must be changed.
Settings: The leak tightness test device does not need any on-site adjustments to its setting. Operating test: While the leak testing device is in operation.
• Open the pressure connector pa. The
leak generated prevents boosting and after 30 secs the device will go into safety mode.
• Reclose the pressure tap pa.
• Reset the leak tightness test device’s
safety catch by pressing the red
indicator. The leak testing device restarts itself and after 30 seconds the yellow light comes on and the control and safety unit is powered up and will start its program.

• Open the quarter-turn hand-operated fuel valve, then immediately close it again.
• Switch the burner on.
• On the control cabinet TC select the manual operation mode S1&- S2 '
• Close the thermostatic circuit.
The leak tightness test device VPS 504 S02 is switched on. After 30 seconds, if the test is validated; the amber light comes on. The control and safety unit is powered on; the red light on the control unit comes on
• Open the control unit and check that it is working correctly.
The program should function in the following way:
- complete opening of the air flap,
- preventilation for 30s,
- return to ignition position,
- 6-second electrode ignition,
- valves open,
- valves closed max 3 seconds after opening,
- burner stops due lack of gas pressure or control unit locks because flame goes out.
If unsure, conduct the above test again.
The unit can only be fired once this very important operating sequence check has been performed.
Firing
Warning:
The burner may be only fired when all the requirements listed in previous sections have been met.
• Connect a microammeter (scale 0 ­100 µA DC) in place of the measuring bridge on the TC (check the polarity).
• Open the quarter-turn hand-operated fuel valve.
• Close the thermostatic circuit.
The leak tightness test is switched on. At the end of the test (30s), the unit is switched on.
• Unlock the control and safety unit.
The burner is in service.
• Check the following:
- combustion as soon as flame
appears,
- any possible gas train leaks.
No leakage should be detected.
• Read the ionisation current (value between 20 and 80µA inclusive).
• Measure the gas flow shown on the counter.
• Raise the power to its nominal output by activating the switch intermittently S3+.
• Check combustion.
Comply with the smoke temperature value recommended by the boiler manufacturer in order to obtain the required effective output. According to the combustion tests, with
the burner operating at the nominal flow rate turn screw V on the MB VEF valve, or screw R on the SKP regulator.
• To increase the CO
2
rate, increase the
ratio and vice versa.
• Read the ionisation current (value between 20 and 80µA inclusive).
• Measure the gas flow at the meter.
• Increase or reduce power by increasing or reducing the value read on the cam I graduated cylinder.
• Stop, then restart the burner.
• Check combustion as soon as the flame appears.
According to the values measured, with the burner operating, turn screw N on the MB VEF valve, or screw D on the SKP regulator.
• If necessary, adjust the cam III value for ignition and the cam VI value for minimum control. Setting is performed in the same way as for cam I.
• Return power to the nominal flow rate and check the combustion parameters. If the value changes when screw N is turned (screw D for the SKP), correct the ratio V (R for the SKP) in the desired direction.
• Obtain the best possible combustion results by adjusting:
- the secondary air setting dimension
Y according to the procedure described in the “Combustion components and secondary air head settings” section.
• Increase dimension Y: the CO
2
rate
increases and vice versa. A modification made to the Y dimension can necessitate a correction of the air flow.
• Check combustion.
• Check operation during the following: firing, increasing and decreasing power.
• With the burner in operation check the leak tightness of the gas train connections using foam designed for this purpose.
No leakage should be detected.
• Check the safety devices.
