Gas cooktop need ventilation

Im interested in purchasing a new gas cooktop, a 30" Bosch. Does it need and special venting above it? I have a microwave mounted above it that has a vent that just basically circulates air (its not vented to the outside) isnt that sufficient?

In the field of indoor air quality a properly sized exhaust hood above a gas range should be vented to the outside and turned on any time the range is in use. If the range is large and the fan necessary exhaust volume reaches 400 cfm then a replacement air system becomes necessary.

The purpose of the vented hood is more than just removing cooking odors it also removes the combustion products. If your current range is gas and you are using a recirculating hood it to should be vented outside.

One of the reasons for the increased concern is the result of today's tighter construction. When homes leaked like mad it really didn't matter. but when you seal things up you end up breathing those exhaust products.

I have relatives that put a vent/microwave combination above their new gas stove. The burners on the stove top put out enough BTU's that the finish on the microwave was damaged. I think it's partially because microwave vent hoods are terrible vent hoods. In your case I would install a proper (single job in life) vent hood that exhausts outside.
