Induction cooktop in Ikea Faktum PROBLEM?

Hello,

I want to install an induction cooktop from Neff in a Faktum base cabinet.
Today, the consultant at the electronics store told me that there must be a 4.5 cm gap between the bottom edge of the countertop and the start of the drawer. This is urgently necessary for the ventilation of an induction cooktop.
I just measured, and it is less than 3 cm.
How did you solve this problem?
Does no one have an induction cooktop in a Faktum base cabinet??

THANKS

Hello, which cooktop is it specifically?

It is not the same but it is the same drawing of this cooktop:

When I look at the drawing, it is not the distance from the bottom edge of the countertop to the start of the drawer, but to the start of the back panel of the cabinet. But the back panel of the base cabinet goes all the way up to the countertop, doesn't it?

You see that correctly. 65 mm from the top of the work surface, with 38 mm, there is 27 mm of space to the drawer. For ventilation, you need to adjust the cabinet, because the specified 2 cm between the back panel and the wall are not given either.

The 65 cm at the front are there. The drawer is slightly lower than the drawer front.

But I do not have the 45 cm at the back, because the cabinet back goes all the way up.
That's normal, which cabinet back ends before the countertop?
