ᐅ Sealing a Ceramic Cooktop to an IKEA Countertop with Silicone?

Hello everyone,
does the cutout in the countertop for the ceramic cooktop need to be sealed with silicone or not?
The Daglig installation manual doesn’t mention this, except for "do not glue the cooktop in" – well, obviously.
The installation instructions for the Boholmen sink say to "seal the cutout for the sink with silicone."
The kitchen installation guide says to "prepare the cutout for the stove the same way as for the sink."
So, which is it?
Also, would silicone around the ceramic cooktop start to smell when the cooktop is in use due to the heat?
Thanks and best regards!

As long as no moisture reaches the joint, nothing will happen. Sealing the edge cannot harm. I have not experienced any odor development, but my experience is based on only 5 cutouts.

Hello Büchenkauer,
usually the rubber seal on the glass-ceramic cooktop provides a good seal. You should not use regular silicone to seal the cutout, as it can release toxic fumes. If you really want to seal it, use heat-resistant silicone. Gluing the cooktop itself in place is not recommended, as it cannot be removed without potential damage in case it needs to be taken out for repairs.
