[. . . ] The works on the burner and on the system have to be carried out only by competent people. Read carefully the instructions before starting the burner and service it. The system electric feeding must be disconnected before starting working on it. If the works are not carried out correctly it is possible to cause dangerous accidents. [. . . ] It's advisable to regulate in such a way as to achieve a closing of the air on the head; this will necessitate a considerable opening of the air shutter which regulates the flow to the burner's fan suction. Obviously, these adjustments should be carried out when the burner is operating at maximum delivery desired. In practice, start regulating by putting the device which closes the air on the combustion head in an intermediate position, start up the burner and make trial adjustments as previously described. When maximum delivery desired has been reached, proceed with correcting the position of the device which closes the air on the combustion head; move it backwards or forwards in such a way as to obtain an air flow suitable to the delivery, with the air regulation shutter in suction considerably open. When reducing the air passage on the combustion head, avoid closing it completely. Check that ignition occurs regularly, because if the passage between the disk and the head is closed, it could occur that the air velocity is so high as to render ignition difficult. If this happens, gradually open the regulator until it reaches the correct position and ignition occurs regularly. It should alsobe remembered that, for the 1st flame, it is preferable to limit the quantity of air to that which is strictly indispensable in order to have safe ignition even in the most difficult circumstances. The burner does not require special maintenance, but it is good practice to check periodically that the gas filter is clean and that the ignition electrode is efficient. It is also necessary to verify that the ignition electrode's spark is produced between the same electrode and the disk. During re-assembly, special attention must be paid to centring exactly the electrodes (ignition and flame detection) in order to avoid them going to earth or short-circuiting which would result in the "shut down" of the burner. The burner operates fully automatically, therefore it is non necessary to carry out any kind at adjustment during its operating. The "block" position is a safety position reached by the burner automatically when some of the components of the burners or the plant do not work properly. It is necessary to check then whether the cause to the problem is a dangerous one before unblocking the burner. The causes to the block may be temporary, for example when air in inside the pipes. When it is unblocked, the burner starts operating properly. If the burner stops three or four times at a stretch, it is necessary either to loock for the problem and solve it or ask for the intervention of the after sales service. Different springs to obtain different pressure values form those described above are not foreseen. To regulate the pressure stabilizer, connect a water manometer to the rubber tube holder installed on the valve, to tap Pa (7), in correspondence with the stabilizer exit. 3) It is not necessary to regulate the rapid opening and closing safety valve (4). Regulating the initial rapid release effects the 1st and 2nd opening positions of the valve. regulation of the rapid release and of the hydraulic brake modify the 1st and 2nd positions of the valve in proportion to the output regulated. [. . . ] It is also necessary to point out that the usual gas filter must be installed near the burner. ) with density of 1, 56 (according to UNI 712872), calculated for a maximum load loss of 0, 5 mbar. For pressure loss of 1 mbar flow rates must be increased by 45%; For pressure loss of 2 mbar flow rates must be increases by 110%. 5) Burner The burner must be ordered specifically for use with liquid gas (L.
