Venting Range Hood - Straight Up?


Working on the kitchen remodel, a bit earlier than originally expected. Thought I'd have plenty of time to research range hoods, but it's turning out that we need to be start moving on it. Right meow. I'm lost in a sea of options. Three questions, hopefully easy ones:

1. Freestanding, stainless 30" range against a wall on 8' ceilings with 39" cabinets within 2" of the ceiling that will receive crown. So I'm guessing I need a wall-mounted stainless 36" wide hood approximately 30" tall. Does that seem about right?

2. I opened the drywall behind where the existing under-cabinet hood is, expecting to see it vented to the ceiling directly above and thru the attic. Not so. Venting material in the wall, but it's abandoned, and the hood was set to recirc instead. Can anybody identify this venting material?





3. I'd like the hood to butt to the ceiling, venting thru the attic and the roof if that's possible, and I'd prefer to repurpose the existing roof hole and remove the abandoned venting material. Is this feasible if I just throw two 45 elbows in there?

Tried to do my research before asking. Hope it shows.

Is that PVC pipe? It's got to go and be replace with solid galvinized pipe.
It does not stick out of the roof so it's exposed, it's inserted into a roof vent.

That looks like 6" oval pipe, oxidized.

I try to put an over-the-range microwave above my ranges, and vent it straight up through the cabinet above with some rectangular duct. Then I transition to 6" pipe and run ridgid up a ways into the attic, then go with flex duct and terminate near the ridge vent.

You vent it inside the attic?? That would never pass inspection here. Even if it did, I wouldn't do it that way.

Venting Range Hood - Straight Up?


It's certainly not PVC. It feels white painted ceramic or metallic. Has a nice hollow thump to it. Fairly weighty. Dimpled like a golf ball IIRC. The vent cap is similarly shaped as an oval or rounded rectangle.

Seems galvy is acceptable for venting ranges. That makes things easy enough.

Do these chimney style hoods butt to the ceiling? Does my body have a picture or diagram of the connection to the venting? Thanks in advance!
