In order to obtain the best combustion efficiency respectful of the environment, it is recommended to control
and adjust combustion using appropriate tools.
Fundamental values to be considered are:
— CO Indicates with how much excess air combustion takes place; if the combustion air is increased, the
2.
CO % value decreases, and if the air is decreased, the CO
2
— Flue gas number (Bacharach). Indicates that solid unburnt particles are present in the flue gas. If exceed-
ing 2 on the BH scale, check that the nozzle is not defective and that it is suitable for the burner and the
boiler (brand, type, atomising angle).
In general, the BH number tends to decrease when the pump pressure is increased; in this case, pay
attention to the fuel flow rate as it increases.
— Flue gas temperature. This value represents the heat dispersion through the stack; the higher the tempera-
ture, the higher the dispersion and the lower the combustion efficiency.
If the temperature is too high, the quantity of diesel oil burnt has to be decreased.
N.B.
The regulations in force in some countries may require different adjustments from those above as well as
compliance with other parameters. The burners of the ECO series have been designed in compliance with the
strictest international standards for energy saving and environmental protection.
The release pushbutton on the equipment is the main component for accessing all the diagnostic functions
(activation and deactivation) as well as for releasing the control and checking device.
The release pushbutton has a multicoloured led which indicates the state of the control and checking device
during operation and when the diagnostic function is in use.
Condition
Standby, other intermediate states
Fuel preheating "on", waiting time 5s.max
Ignition stage
Correct operation
Incorrect operation, current level of
flame detector below permitted minimum
Drop in voltage
Burner lock out
Fault (see table on page 8)
Stray light before burner ignition
Rapid flashing for diagnostics
If the burner is locked out, there will be a steady red light on the lock out pushbutton.
By pressing the transparent pushbutton, the control and checking device will be released. By pressing it for
more than 3 seconds, the diagnosis stage will be activated (red light flashes rapidly). The table below de-
scribes the causes of the lock out or fault in relation to the number of flashes (always red).
The diagnosis function is interrupted by pressing the release button for at least 3 seconds.
