5. Adapting to different types of gas
Before carrying out the operations described below, disconnect the appliance
from the electricity supply.
The hob is tested with G20 (2H) natural gas at the pressure of 20 mbar.
If it is to be used with other types of gas, the burner nozzles have to be changed and
the primary air flow adjusted.
To replace the nozzles and adjust the burners, the hob plate has to be removed as
described below.
5.1 Removing the hob skin
Remove all the burner components in the numerical order shown below:
• Remove the pan stands (Fig.1) by lifting them at the back (1) and extracting them
(2). (On 70 cm hobs remove the central pan stand first; on 60 cm hobs the right-
hand pan stand must be removed first);
• remove all the knobs (3, Fig.2) by pulling them outward;
• lift all the burner components off the hob (4-5, Fig. 2);
• use the spanner 6 (Fig. 3) to open the bayonet fastenings of the burner fixing rings,
applying leverage on the guides 7;
• after removing all the components described above, lift the front of the hob skin (8,
Fig. 4).
• the burners and gas taps can only be accessed by pushing the rear of the hob
gently upwards with the aid of a tool (9-10, Fig. 5).
This is necessary to release the internal snap fixing devices. The hob skin can now be
removed. Some models may have 2 additional pins at the side (Fig. 5), which must be
removed in the same way, using a tool to apply leverage to the hob.
