Cleaning and care
The surface of the burner caps will
become more matt over time. This is
normal and does not indicate damage
to the burner caps. Nor will it affect
the operation of the cooktop.

Assembling the auxiliary, semi-rapid
and rapid burners
 Place the burner head  on the
burner base  so that the ignition
safety device  and the ignitor 
extend through their respective holes
in the burner head. The burner head
must click into place correctly.
 Place the burner cap  flat over the
burner head . When correctly
positioned, the burner cap will not
slide about.
Ensure parts are reassembled in the
correct order after cleaning.
