Can a recirculating venting hob be installed in a sealed island cabinet with no vents?

[TurtleShuffle]

I’m looking for clarification on the installation requirements for a recirculating extractor induction hob in a kitchen island.

The hob is an AEG TCH74B01CB venting induction hob, installed in recirculation (internal) mode, not ducted externally.

The current cabinet configuration is as follows:

• The hob is installed in an island unit.
• There is a sealed, non-opening drawer directly beneath the hob.
• There is a void within the island, but the void is fully sealed on all sides, including at floor level.
• There are no ventilation grilles, cut-outs, or airflow openings anywhere in the unit.

The kitchen supplier have advised that no ventilation openings are required because the hob is “internal / recirculating”.

My understanding is that, even in recirculation mode, a venting hob still relies on airflow into and out of the extractor system, and that installing it above a sealed cabinet with no ventilation path may prevent correct operation and could cause performance or overheating issues.

My question is:

Is it acceptable installation practice for a venting / extractor induction hob to be installed over a fully sealed cabinet with no ventilation openings, or should there be some form of cabinet ventilation or airflow path provided?

I’d read the MI’s or ring the manufacturer

You don’t need an extractor by the hob if there is a sufficient one elsewhere in the room. I installed an induction hob in the island and a recirculating extractor above. I just had to install a decent proper one in the wall to comply.
