Ventilation requirements (all countries except UK)
Providing adequate ventilation
The installer must refer to the current local regulations.
The room accommodating the gas cooktop must have
adequate natural draught to allow combustion of the gas.
The flow of air must come directly from one or more air vents
made in the outside walls with a free area of at least 100 cm
2
.
The vents must be positioned close to the floor, preferably
on the opposite side to the gas burners of your cooker (as
shown in Figs. 1a and 1b). The vents must be designed in
such a way that they cannot be obstructed either from
the inside or the outside.
When it is not possible to provide the necessary vents,
the draught may be supplied from an adjacent room,
ventilated in the required manner, provided it is not a
bedroom or an area at risk. In this event, the kitchen door
must be opened to allow the draught to enter the room.
Extracting cooking and gas fumes
Important!
This appliance is not connected to a device extracting the
products of gas combustion. Such a device must be installed
and connected in accordance with the installation rules in force.
Take special care to provide adequate room ventilation as well.
To eliminate cooking and gas fumes, extractor hoods
ducted directly to the outside must be installed. (Fig. 1a).
If this is not possible, an electric fan installed in an
external wall or window may be used; the fan should have
a capacity to circulate air at an hourly rate of 3 to 5 times
the total volume of the kitchen (Fig. 1b). The fan can only
be installed if the kitchen has suitable vents to allow air to
enter, as described under ‘Providing adequate ventilation’
above.

Installation instructions
When connecting the cooktop to the gas supply with rigid pipes or a flexible
hose (which must comply with BS 669 in the UK), make sure that:
you use rigid pipes or a flexible hose compliant with applicable local regulations. The flexible
hose shall be of the correct construction for the type of gas being used and of the correct size to
maintain the heat output of the appliance
the connection with rigid metal pipes does not cause stress or pressure to the gas piping.
the flexible hose is not under tension, twisted, kinked, or too tightly bent, neither while the
cooktop is in use nor while it is being connected or disconnected
the flexible hose is not longer than 2000 mm (or refer to applicable local regulations) and does
not come into contact with sharp edges, corners, or moving parts, as these may cause abrasion.
Use a single flexible hose only; never connect the cooktop with the more than one flexible hose.
the flexible hose can easily be inspected along its entire length to check its condition; if it has an
expiry date, it should be replaced before that date
if using a flexible hose which is not entirely made of metal, make sure that it does not come into
contact with any part of the cooktop with a surface temperature of 70
o
C or above.
the rigid pipe or flexible hose is replaced if it shows signs of damage
the flexible hose is not subject to excessive heat by direct exposure to flue products or by
contact with hot surfaces
the socket into which the plug of the flexible hose fit is permanently attached to a firmly fixed
gas installation pipe and is positioned so that the hose hangs freely downwards.
the plug of the flexible hose is accessible after installation, so that it can be disconnected for
service or removal
you inform the customer that the rigid pipe or flexible hose should not be subjected to
corrosion by cleaning agents.

Converting the cooktop to a different gas type
Important!
Only a suitably qualified and registered person may convert the cooktop to a different gas type.
To convert from one gas type to another, you need to replace the injectors, and then
adjust the minimum gas rate setting.
Replacing the injectors
1
Remove the pan supports and burners from the cooktop.
2 Using a spanner, remove the injectors and replace them with ones suitable for the type of gas
you are converting the cooktop to. See the ‘Table for the choice of injectors’.
The burners are designed so that regulation of primary air is not required.
Adjusting a burner’s minimum gas rate setting
Check whether the flame spreads to all burner ports when the burner is lit with the gas valve set
to the minimum position. If some ports do not light, increase the minimum gas rate setting.
Check whether the burner remains lit even when the gas valve is turned quickly from the
maximum to the minimum position. If the burner does not remain lit, increase the minimum gas
rate setting.
To adjust the minimum gas rate setting
1
Make sure the burner is lit.
2 Turn the knob to the minimum position.
3 Remove the knob.
