GAS TRANSFORMATIONS AND ADJUSTMENTS

Replacing the nozzles

If the equipment is adjusted for a type of gas that is different from the original, it is necessary to replace the burner nozzles as well. The nozzles used to replace the original must be in accordance with the table of the technical characteristics enclosed.

To remove the racks and burners by means of a straight spanner ‘L’, unscrew the nozzle ‘U’ (Fig.8) and substitute it with the corresponding one and tighten the nozzle.

Adjusting the burners

The flame should always stay alight when the burner is switched on, even if there is an abrupt shift from the maximum to minimum flame position. If the flame does not stay alight, adjust it as follows:

–Start the burner

–Turn the tap up to the minimum position (small flame)

–Remove the knob from the tap rod

–Using a flat-tip screwdriver ‘C’ into the hole ‘F’ of the tap (fig.9) turn the by-pass screw up.

MAINTENANCE

Lubricating the taps

In the case of tap hardening, it is necessary to disassemble the tap and grease it.

–Unscrew the two screws that lock the head flange of the tap.

–Lift the gas adjusting cone and carefully clean it with gasoline or diluent.

–Spread a little high-temperature grease on it, making sure that the gas holes are not obstructed.

–Reassemble all of the parts with care.

Replacing the power supply cable

If the power supply cable needs to be replaced, it is necessary to use a cable with a section of 3x0.75mm2, type H05VV-F or H05RR-F, complying with the regulations in force.

NOTE:

The connection to the terminal board must be effected as shown in fig. 10 - 10A:

Brown cable L (phase)

Blue cable N (neutral)

Green-yellow cable (ground)
