8.3.3
For easier cleaning, the flame spreader crowns can be removed; wash them with
warm water and a non-abrasive detergent making sure to remove any encrustations
and wait until they are perfectly dry.
The burner pins A must be inserted in the housings B in the burner crown. The holes
C in the latter should be slid over the igniters and thermocouples D on the hob.
8.3.4
For correct operation the igniters and thermocouples must always be perfectly clean.
Check them frequently and clean them with a damp cloth if necessary. Remove any
dry residues with a wooden toothpick or a needle.
