Adapting the hob to different types of gas
To adapt the Hob for use with different types of gas, carry out the following instructions:
— remove the grids and burners
— insert the hexagonal spanner (supplied) into the burner support (Fig. 5)
— unscrew the injector and replace it with one suitable for the gas to be used (see
Table page 28).
When you have carried out the new gas regulation, replace the old gas rating plate
on your appliance with one (supplied with hob) suitable for the type of gas for which
it has been regulated.

and 0,75 mm

for others products. Also, the maximum external diameter of the cable
should not be greater than 7 mm.
Declaration of compliance. The parts of this equipment which are designed to come
into contact with foodstuffs, comply with EEC directive 89/109.
Appliance complying with European directives 89/336/EEC, 90/396/EEC,
73/23/EEC and subsequent modifications.
The rating plate on the hob shows the type of gas with which it is designed to be used.
It is possible to use other types of gas after carrying out some simple modifications.
a) Connection to the gas supply
— connection to the mains gas supply or gas cylinder should be carried out according
to the relevant national standards, after having checked that it is regulated for the
type of gas with which it will be supplied. If it is not correctly regulated follow the
instructions in the paragraph entitlet «Adaption for different types of gas». For liquid
gas (cylinder gas) use pressure regulators which comply with the relevant national
standards.
N.B.: for safe operation, economic use of energy and to ensure greater durability
of the appliance, make sure that the supply pressure conforms with the values shown
in the table on page 39
— Connection to a rigid pipe (see instruction on page 44)
Connection to the gas supply should be done without putting any kind of stress on
the appliance.
— Connection to a flexible steel pipe (see instructions on page 44)
The junction of the gas pipe with the appliance is a 1/2” gas tapered thread connec-
tion. Use only pipes, washers and sealing washers which comply with the relevant
national standards.
The fitting of these pipes should be done to that their
maximum length, when fully extended, should not
exceed 2000 mm.
N.B.: carry out a final check for leaks on the
pipework using a soapy solution. Never use a
flame. Also, make sure that the flexible pipe
cannot come into contact with a movlng part of
the cabinet (eg, a drawer) and that it is not situa-
ted where it could be damaged.

REGULATING THE BURNERS
Flame Combustion
For maximum efficiency from the burners, the correct combustion of the flame is ne-
cessary. A good flame must be well aligned and without yellow tips (Fig. 7/B). If there
is insufficient air, the flame will be uneven with yellow tips (Fig. 7/A). If there is too much
air, the flame will be very short and bright (Fig. 7/C). In these cases the combustion
must be adjusted by re-fitting the carburation tube to the Venturi (where there is insuffi-
cient air) or removing the carburation tube (in the case of too much air). To position
the carburation tube, the fixing screws must be loosened, and retightened when the
satisfactory combustion is obtained.
