should be taken
into account when choosing
the length of the screws for
the fixing hooks:
• 30 mm thick: 17.5 mm screws
• 40 mm thick: 7.5 mm screws
Fix the hob as follows:
1. Use short flat-bottomed screws to fix the 4 alignment
springs in the holes provided at the central point of
each side of the hob.
2. Place the hob in the cavity, make sure it is in a
central position and push down on the whole perimeter
until the hob is stuck to the supporting surface.
3. For hobs with raised sides: After inserting the hob
into its cavity, insert the 4 fixing hooks (each has its
own pin) into the lower edges of the hob, using the
long pointed screws to fix them in place, until the glass
is stuck to the supporting surface.
!
The screws for the alignment springs must remain
accessible.
