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 of gas consumption)
— carry out regulation of the burner.

Electrical connection
Check the data on the rating plate, located on the outside of the unit, to ensure that the
supply and input voltage are suitable.
Before connection, check the earthing system.
By Law, this appliance must be earthed. If this regulation is not complied with, the
Manufacturer will not be responsible for any damage caused to persons or property.
If a plug is not already attached, fit a plug appropriate to the load indicated on the rating
plate. The earth wire is coloured yellow/green. The plug should always be accessible.
Where the Hob is connected direct to the electricity supply, a circuit breaker must be
fitted with at least a 3 mm contact spacing when in the open position.
It if is necessary to replace the connecting cable, the earth wire (yellow/green) must,
by law, be approximately 10 mm longer than the live and neutral wires. Cable type
H05RR-F, H05VV-F, H05V2V2-F must be used.
The cables should be 1 mm

section, also, the maximum external diameter of the ca-
ble should not be greater than 7 mm.
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.
(See the instructions in the following paragraphs).
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 38
— 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
For maximum efficiency from the burners, the correct combustion of the flame is neces-
sary (see table of gas consumptions quota “X”). 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 yel-
low 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 sati-
sfactory combustion is obtained.
