Installing a range hood with existing ductwork
5 Attachment(s)
Hey folks, I hope you are doing well. I have learned alot from the forum and appreciate this resource. Thanks for sharing your knowledge. :thumbup:

I need some help and I would appreciate your thoughts on the proper installation of a range hood in the kitchen. I've attached a few photos and drawings. The old hood vented through a 6" duct in the ceiling, which turned 90 into a 10" duct which goes straight up through the roof. I was just going to connect the new range hood to the old duct work, but....

The 10" vertical duct also goes straight down to the stove level where there is another 90 and dead ends right over the stove level in the wall. The 10" duct is lined with some kind of clay which brings it down to 6" diameter. This portion of the duct is not used, and seems like it was for an old style stove / oven. (My house is a one level rancher built in the 1950's)

What I'd like to do is remove the 10" duct below where the range hood vent connects. My range hood duct will then have two 90s and go from 6" to the existing 10" duct.

What do you folks think?

Could the lining be an asbestos material?

Thanks in advance.

Looks okay to me. I can't say if asbestos is there or not, though.
