Blanco BC 75 X manual Substitution of the nozzles, Regulation of the minimum, Tap

Adaptation to different types of gas

WARNING: Servicing shall only be carried out by authorised personnel.

Substitution of the nozzles

-Remove the grills;

-Remove the caps and baffles from the burners;

-With a tubular spanner no. 7 unscrew and remove (fig. 8) the nozzles substituting them with those corresponding to the type of gas used (see table on page 18);

-Remount the parts carrying out the operations described in reverse. Upon completion remove existing gas type label and stick the relevant gas type label near the gas supply pipe.

If the pressure of gas used is different (or variable) from that foreseen an appropriate pressure regulator should be installed on the entry tube. In case pressure regulators for U-LPG are used these should conform to the regulations in force.

Regulation of the minimum

To regulate the minimum:

-bring the tap to the minimum flame position.

-extract the knob.

-in case of conversion from natural gas to U-LPG, tightly screw the by-pass screw (Fig.9);

-when converting from U-LPG to natural gas unscrew about ½ turn by-pass screw, until a regular small flame is reached.

Finally check that by quickly turning the tap from the maximum position to the minimum position the burner is not extinguished; remount the parts carrying out the operations described in reverse.
