THE PANSTHE PANS
If you choose a pan with this logo, you will be certain that it is absolutely compatible with your induction hob under normal condition of use
The compatible induction pans must be made of a magnetic material :
• Enamelled steel pans with or without non-stick coating
• In cast iron with or without enamel coating
• In ferrous stainless steel – laminated stainless steel
• In aluminium with special bottom
We advise to choose pans with a thick bottom and a minimum diameter of 12 cm (i.e. 5 inches) for even more cooking : the heat spreads more evenly

1- In case of a small cross piece, there is no problem
2- In case of a rectangular cross piece or with a closed top, make a bevelled cut so that air comes out of the hob
3- In case of an intensive using with more than 1 cooking zone, we advise to make an opening on both sides of the unit
