Final attempt to salvage my 42" antique copper hood, before I give up and buy a stainless steel chimney wall hood or something: (see pix below)
- I have this 42" wide antique copper hood shell
- I am having trouble finding an insert that fits w/in this shell: mainly because the "lip" or "brim" of the hood is only 3", and most inserts need 4"+ (something about the ability to hang the baffle filters)
- New idea of using external blower, so that I am not limited to a smaller/weaker cfm internal blower.
- But does my setup allow for external blower? Hood needs to go up ~12" and 90degree turn left ~45" to go outside
- How exactly does external blower system work? Is there a complete diagram?

Notes:
- Waiting for Mark from Tradewind to get back to me w/ ideas of what his engineers can customize

- Broan/Nutone technician said they don�t have anything that fits my hood

- Do I talk to a local HVAC person? What do I ask for?

- One possibility is to reuse the old Tradewind insert that I have (w/ the mesh filters) attach it to an external blower????

I am not 100% attached to this copper hood, but I do like it. I like the shape and the fact that it is an antique and not some generic hood from the manufacturing line.
But I could live w/out all the hassle/run-around.

Really appreciate any ideas/help.
As my friend Kristin (thrilledtoremodel) said, do not give up until you run it by the gardenweb. They are creative; they will come up with something!

Thank you!

Wants:
- 900+ CFM (I fry, garlic/oil, fish, etc A LOT � need to remove the grease and smell). Yes, I could live w/ 600cfm (better than the 0cfm that I had).
- Baffle filters (instead of mesh)

Limitations:
- Ceiling height = 91"
- Option A. If I stay UNDER the ceiling, I have only 13.5" from hood top to ceiling bottom for transition piece + elbow ducting
- Option B. If I go THROUGH the ceiling joist space, I gain another 7", but then I�m limited to 7-8" ducting (to go out the house)
- Budget: cannot spend over $2000

91 height
36 base cab to countertop
29 countertop to hood bottom
12.5 height of hood
Leaves 13.5" from hood top to ceiling bottom for transition piece + elbow ducting

My layout: hood is label "Pots/Pans"

will custom build a hood liner to your exact specs--size, depth, location of ductwork, type of blower (internal vs external--although the shallow height of your hood would likely be better accommodated with an external blower), lighting choice etc. You should end up with a SS liner with the preferred baffle filters, which would drop into your unit like a glove. And at a price that's surprisingly close to off the shelf units. And with superb hand craftsmanship, made in America.

I post this repetitively, I know, but I love my MA hood just as much 5 years after installation as I did when we installed it. One of the best things in my kitchen.

If this was my hood I would send it to Modern-Aire and have them refurbish the hood and fit the insert in the factory.

In addition, a series of duct sections connects the fan to the hood (or hood liner). Duct configurations can accommodate a lot of variation in house construction. There should be a damper at the hood, and depending on the style of the roof fan, one at the fan.
