5.Adapting to different types of gas

Before carrying out the operations described below, disconnect the appliance from the electricity supply.

The hob of the cooker is adjusted for use with either natural gas at a pressure of 1.0 kPa. If used with other types of gas, you have to replace the nozzles, then adjust the minimum flame on the gas taps. For nozzle replacement and burner adjustment operate as described in the following paragraph.

5.1Removing 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.
