Island Ventilation - Contractor Talk - Professional Construction and Remodeling Forum

Milhaus · 02-06-2008, 11:13 PM

I have a customer whose countertop stove is on the island. They are interested in ventilation for the stove. I'm curious if there are any suggestions for downdraft ventilation for the stove? There is an 8 inch raised countertop directly behind the stove, so it could potentially be mounted behind the stove. The other thought I had was to put something in the ceiling. I've heard of some ultra quiet ventilation systems that work well mounted on the ceiling.

thanks,

That's why they invented Jenn-Aire.

I question whether there is really enough venting capability to pull ALL the smoke down with a Jenn-aire. Even from the outside burners?

The only times I've seen problems
were when someone got
"creative" with the duct work.

None of the residential units will capture all the smoke. They just don't move enough air.

Overhead units do a better job of removing funk, but the side and down draft units (Jenn-Air, Dacor) do a good job. I'd put one in my home, and I'm a cooking maniac.

For the Dacor, you can have a remote blower, an inline blower, or a built in blower. Do read up on them or visit your local dealer/reseller for all the details.

Takes a bit more planning, but sounds like one of these type of units will work well for you.

Price = not cheap.

No, they invented JennAire so people could have something to hate after they spent a lot of money paying for it. There is not a down draft vent out there that is worth the box it's packed in.

There are some very nice ceiling hung vents on the market. Like everything else, the ones that work are not cheap though. The GE's are not bad, but my favorite is the Broan Best. Very neat and simple, twin blowers that will suck your shirt off (1000cfm's) and the best rack on the market for the filters.
They are even available with exterior remote blower , which I am not a big fan of, but it's there if required.

I know Dacor are considered top end products, but every time we install them, the customer always reports a never ending series of problems with the electronic circutry in them.

The point of my other post exactly. If you are downdrafting enough air to effectively pull smoke or steam down from the height of the top of a pot, especially on the outside burners, you would not have any flame/heat left.

Why don't people understand that for any mechanical device to be successfull, it must work with the laws of physics(heat and smoke rise naturally), not try to overpower them. It is like mounting gutters on the ridge of your roof and believeing that you can install a mechanical system that will be effective at making the rain water run up to them.

What about the ones that rise up behind the the stove and vent down? I have seen them in houses but never had the opportunity to install one but they seem to work and they vent down. The customers seem to like them and they usually rise high enough to draw from the top of the tops to obey the laws of physics. I don't remember the brands though.
