Since these are both exhaust flues and ducts, no clearances are required. Clearances are only required when an air intake vent, door or window opening is located near a flue exhaust, vent hood or dryer duct terminal. You do need to consult your building code office, however, because there has been a change in some mechanical codes this year that require the installation of 'make-up air' ducting when using an exhaust hood rated over 400cfm. If you do not already have a make-up air intake duct, your code may now require one, and if it doesn't, you should still consider adding make-up air anyway.

If you have sufficient space on the other side of the stove, you will be ok, but it is not ideal. I have the 12" now and it is not very useful. Another few inches would have made a difference. BTW - we are extending and re-doing our kitchen, so I could have laid it out as I chose and I ended up with the work area as a galley and have another area nearby (a peninsula) for when I need to spread out and the normal size is not enough. I was mindful of trying to avoid corner cabinets and even worse, a corner sink. Our counters won't even need seams because one side has the sink in the middle and the stove is in the middle of the island. A galley can be laid out easily and is much better than an equal about of linear space on one long run. Everything is nearer and a simple pivot gets me to the sink area and fridge. In my current smaller kitchen, I have over 6 feet between my stove and sink with a dishdrain in the middle of just going in a straight line. If anything is dripping, it has a long way to go... It also makes emptying the pasta pot very dangerous. In our new layout it will be just over half the distance. Can't wait.

Mike, thank you! I do indeed have a picture or 5 or 6 from my back deck. But you must promise not to laugh. I have gardened for a long time -- but in the back of a big brick colonial in full sun. After 10 years I had a really lovely Southern garden built around a pretty carefully curated collection of ~150 roses, from Old Blush on up through the ages. The old teas and noisettes were my favorites. THAT was maintenance, LOL. But just as you note, that was also about (ever expanding) beds,... Life changes and now I am single again, caring for a very sick mother who lives with me, communing to work in Philadelphia, trying to rehab a house and learning to garden in a new way. I mention all this to beg a little bit of a pass on my unimpressive results to date -- its hard to find time to study and learn! That said, what time I do have is devoted not to trips to the tile store, but to this -- there's an image "just below the surface" -- its compulsion. And given how precious that time is, it feels awful to be floundering! I am so grateful for your note. The site is not easy to photograph because when the sun is out, the camera really exaggerates the shadows; therefor I'm uploading shots taken on overcast days. The setting is a suburban woodland of ginormous red, white and chestnut oaks and tulip poplars that slowly are giving way to runs of American beech. It is hillside watershed into a Potomac river tributary. Soil is two or three decades of leaf litter sitting on top of marine clay, and that clay is important to keep stable. The backyard is on the south side of the house -- the sun travels right over my roof line, is blotted by 2:00 p.m. by a big old white oak on my west wall. It is a pie shaped lot, the narrow end deep in the woods. The first picture is from last fall, looking at the back of the house from about half-way to the back property line. That's metasequoia "Miss Grace" planted high on some big rocks (that can be repurposed eventually). On the far left, a very old, not terribly lovely Fosters holly (I think) -- the end of a screen of now 18 footers that I've been trying to rehab with pruning but... The second photo is from early this spring-- my little Lilliputian garden secreted among those great big trunks. [All the cryptomeria here took a bad hit with the freeze/thaw cycle this spring]. I was okay with the idea of a "grotto" as the best I would be able to do in the shadows. But when the big oak off my deck that so intimately connected the house to the woods finally gave up and came down, everything changed. In the photo below, the rocks along the property line on the right (which extends another 20 feet beyond the rocks) I put there with the idea of filling in the grade a bit, but want someone trained in water/erosion control to keep me from making a mistake I might regret. I imagined, and still do, a small pondless falls next to the big stump on the far right -- not for splash, just for some sense of movement. Now that I am thinking bolder, I also imagine that the "source" for that falls is a very shallow "destination" pond roughly behind the azaleas (in the photo below it would be mostly screened by the top of the variegated dogwood). The dogwood is Samaritan -- just one of many poor choices/placements I've made -- it will get too big to between the sun and everything that is behind it. The river stones I was just playing with. Those will go away. You can just make out the deck coffee table in the photo below, where I imagine a bench would be. The Nootka (oddly my favorite thing in the whole yard-- I love weeping forms and this one just makes me smile) also is poorly placed, probably should be snug up against the big stump to backdrop the vignette of a the falls, with a red dissectum in there somewhere (I have 1 gallon Shaina, Temukayama, Red Dragon, and Orangeola waiting for homes), and a bigger boulder than I have. I also went with Alice hydrangeas on the left for scale, but honestly I do not like them, at least not now -- they are coarse -- another variety would be lovelier. Or something else fronting that stand of oaks. The Atlas Cedar was another inexpensive chance taken -- I'm fond of him but tall as he is, he'll get no respect inn that spot. Apricot carpet roses in front of the hydrangea were meant to help call him out. Not shown here are a recently purchased an "at your own risk" 6 foot Seiryu that needs a home and an Omurayama that I imagine on the property line next to the "pondless" pond, this side the stump. And Red Sentinel, back there just to the left of the wood pile, is not his best self in that shade, neither red nor sentinel-like. Seems like his columnar shape should be next to a trunk. LOL, Where do I start from here? Lay in the hardscaping, re-position the existing trees...purchase many more... but this time with something like a plan. I sure could use a steady hand to guide me..

@Stoveguyy - I was thinking the same thing... I blame Fixer Upper for making it all look so easy. How in the world do they do all that and stay within those budgets?!!! Yes, we thought of all those expensive things you listed. We are trying to figure out how to keep the family room fireplace and still have an open floor plan. Sadly, it is a big obstacle right in the middle - backs up to and blocks access to a unused living room that 28 x 15. Thank you for your thoughts.
