How to connect a kitchen duct to microwave?

Hi Sam. Any progress on the microwave range hood install? You maybe able to use a round duct plate adapter and the attach a round damper to it. That will save you considerable space and should be enough to be able to make the connection to the current duct. I wouldn't reduce the ducting to anything smaller than the manufacturer's recommendations.

Here are the links for the items I mentioned. I could only find in 7" diameter, which seems to be standard size.

The other thought I had, was to go straight up through the ceiling, into the attic and through the roof. Obviously that will only work if you have a bungalow type house.

Good luck.

Hi Steve,

Not a bungalow unfortuntely ;)

We looked at where the bottom of the duct and it was actually 1/8" below the cabinet. Had we put in a 30" cabinet (rather than a 20") it would have allowed for the duct, but would have created a 17" gap between the stove and microwave which is too small. We ended up deciding on a recirculating microwave.

If, in the future, we decide to sell we may just figure out a way to move the duct, but for now the recirculating option is best as we don't do much greasy cooking anyhow.

Hi:)

I have exactly the same issue. I'm just in the process of having my kitchen renovated and I was very interested in getting an over the range microwave. I did my own research and compared some good brands here . As I have a limited space, I'm going to put a microwave over the top of a range hood.
