Hoover HI642CBB Instruction Manual page 11

Use pans whose diameter of the ferromagnetic area (base of the pan) is in the
range of dimensions in the table below. (Table 1)
- If you use smaller pots, performance could be affected
- If you use pot with a diameter smaller than the one indicated in the table
above, pots may not be detected
According to the dimension of the zone you can use pots of different diameters
as picture below:
If the ferromagnetic part covers only partially the base of the pan, only the
ferromagnetic area will heat up, the rest of the base may not heat up a sufficient
temperature for cooking.
If the ferromagnetic area is not homogeneous, but presents others material such
as aluminum this may affect the heating up and the pan detection.
If the base of the pan is similar to the pictures below the pan could be not
detected.
