INSTRUCTIONS FOR THE INSTALLER
Electric connection
The connection to the electric grid must be carried
out by qualified personnel and in conformity with
the regulations in force.
The voltage of the electr ic system must
correspond to the value indicated in the label

GAS TRANSFORMATIONS AND
ADJUSTMENTS
Replacing the nozzles
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. 8) and substitute it with the
corresponding one.
- tighten the nozzle strongly.
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. 9) and turn the by-pass screw up to a
proper adjustment of the lowest flame point.
As regards propane gas burners, the by-pass
screw must be tightened completely.
MAINTENANCE
Lubricating the taps
In case of tap hardening, it is necessar y 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 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 should be replaced, it is
necessary to use a cable with a section of 3 x 0.75
mm2, type H05VV-F or H05RR-F, complying with
the regulations in force.
The connection to the terminal board must be
effected as shown in fig. 10:
brown cable L (phase)
blue cable N (neutral)
