Venting for cooktop located in kitchen island.

I currently have an electric cooktop with a downdraft system that carries smoke and fumes through ducting to the outside of my house. I'm planning on installing a gas cooktop and since the downdraft system has never worked as advertised is it really necessary to install a new downdraft with the new cooktop.

We have a downdraft vent with a gas cooktop and it works great. Too good sometimes in fact, on 'high' it actually pulls the gas flame towards it and results in uneven heating.
Perhaps you need more cfms?

I had downdraft in my last house. It sucked. On low, it captures nothing. On high, it captures a bit more, but it pullls the flames sideways and still isn't efficient.
You can get an island vent hood that is finished on all four sides for over-stove use. That's a way, way better choice if you actually cook & use your stove frequently.

this ^^^^^^
just like over the stove upvents you can use cheap crappy vents that dont do much or good quality vents that move more cfms and work fine
if the house was a model home builder then they saved $200 to give you the cheapest of the cheap crappy venting no matter how much your house cost.

It's been a while since I looked it up but this is what I remember: Code requires/required you to have a vent only if the cooktop's manufacturer requires one. However, if you do have a vent, it has to vent out of the home. You can't just vent it into the attic. Again, this is old info so feel free to check me.

If you don’t mind please provide manufacturer and model. Thanks for the post as well.

It's an older GE Profile range top model JGP990SELSS with a built in downdraft. 400cfm, 6" ducting venting to the outside about 5' away.
