Replacing the nozzles for burners A -SR -R
If the equipment is adjusted for a type of gas that is different from the one available, it is necessary to replace
the burner nozzles.
The choice of the nozzles to replace must be made according to the table of the “technical characteristics”.
Act as follows:
- Remove the racks and burners.
- by means of a straight spanner L, unscrew the nozzle U (fig. 7) and substitute it with the corresponding one.
- tighten the nozzle strongly.
Replacing the nozzles for double ring
To replace the nozzles must be remove the ceramic plate:
- to replace the nozzle U1 (central burner) unthread the nozzle holder from the burner seat (fig. 7/A)
- replace the nozzle U2 (outer burner) (fig. 7/B) directly from burner seat.
Adjusting the burners
The lowest flame point must always be properly adjusted and the flame must remain on even if there is
an abrupt shift from the maximum to the minimum position. If this is not so, it is necessary to adjust the
lowest flame point as follows:
- start the burner up
- turn the tap up to the minimum position (small flame)
- remove the knob from the tap rod
- introduce a flat-tip screwdriver C in the hole F of the tap (fig.8) and turn the by-pass screw up to
a proper adjustment of the lowest flame point.
As regards G 30 gas burners, the by-ass screw must be tightened completely.
MAINTENANCE
Lubricating the taps
In case of tap hardening, it is necessary to disassemble and grease it.
These are the operations to carry out:
- Unscrew the two screws that lock the head flange of the tap.
- Lift the gas adjusting cone and carefully clean it with gasoline or diluents.
- 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 should be replaced, it is necessary to use a cable with a section of 3 x 0.75 mm²,
type HO5VV-F or H05RR-F, complying with the regulations in force.
The connection to the terminal board must be effected as indicated:
brown cable L (phase)
blue cable N (neutral)
green-yellow cable (ground)
