Yeah, I think you've got potential problems if the vent stack that contains your kitchen duct runs in the same chimney chase that is also used for a fireplace below, or even just other peoples' vented stuff. Couple of issues: the air inside a fireplace stack is really hot - and needs to be in order for it to draft. Perhaps that's not for the fireplace, but for another kitchen exhaust stack? Another kitchen vent stack would be the least worrying because of what is carried up by a kitchen fan: cooking heat, steam, odors and some grease, annoyances but not really dangerous. Any burning appliance or fireplace vented to the stack would be a major worry for me. However if it is a fireplace stack (and except for woodstoves, or fake gas-fired fireplaces) the chimney on a wood-burning fireplace is pretty big, perhaps 15 X 15 inches square. The other issue is that the exhaust from the chimney (or from any other combustion appliance) could be sucked back down into your kitchen under certain atmospheric and draft circumstances, which depending on what is being ventilated could be dangerous or fatal to you. You really need to investigate what's being sent up in the other flues! Espcially dangerous is a vent stack from a gas or oil-fired water heater, furnace or boiler. Leaks among the vent stacks are a small issue, the main issue would be backdrafting which could be drawing stuff from one stack back down into the living space of another unit. That's scary. Do you know the symptoms of carbon monoxide poisoning? It's colorless, odorless, and deadly. The early warning of slight, persistent carbon monoxide poisoning is a feeling of malaise, tiredness, sometimes with cracking headaches that disappear pretty promptly when you leave the building. And with higher levels a bright red coloration to your face, like you get when you're out of doors in really cold weather. You can get a carbon monoxide detector where smoke detectors are sold. Now about your own venting: can you get the vent to the exterior of the building and just vent to a wall? Your tile roof doesn't preclude having the exhaust there. I have a slate roof and with proper installation of the roof jack, with careful flashing, etc., there should be no problems with it. You will need a skilled and competent tile-roof worker doing that part of the job (opening the roof, installing the roof jack, flashing like a maniac around the opening and re-installing the tile field around it.) I would only trust a tile roof expert with that part because tile is so different from regular asphalt or shingle roofs. The ducting itself could be done by an HVAC guy, but probably the guy who installs the fan will be able to do that part. As for how they work on the non-step roof surface - that's easy - they use roof ladder brackets that hook the ladder over peaks. Then they only step on the ladders which avoids breaking the tiles. I do all my own slate roof repairs and that's how I do it. If the roof is particularly high and challenging, they will bring in a bucket platform truck to work from. That's a pricier option. The roof may not be as daunting as it appears to someone who doesn't do roof work regularly. I work on my three story tall hay barn, using only roof ladders, and a fall-arrest safety harness, of course. Howver, as noted the MUA (make up air) may be more of a problem than the exhaust stack pathway. It can be done - solving these issues is what the GC does to earns his whack. Since you're keeping that part in your bank account, you'll have to find the right guys yourself. But don't skip figuring out what's running through that chase from other units, even if you decide to vent through the roof. HTH L.

fancypants2008----i first saw these lights at napastyle but they were backordered forever. then i bought them from ballard design. once i purchased them, they pulled them off the website. it ended up i got the last two!!!! someone just posted on another thread that they found them on "urban cottage".....i think that was the website. they are mercury glass silver pendants....they backsplash is a raised alabaster basketweave with ming green dots. i got it from elon tile. their website is awful so maybe you can find it at a local tile shop. if you need anymore details, i can provide you the tile shop that i used (rochester, ny) cheril27---when looking for a kd, i gave all that i interviewed my inspiration picture of this hood. i did have some designs done with cabinets on both sides. the reason i opted out was simply the size of my space. i really wanted a 36 inch cooktop so i couldn't fit cabinets on that wall. now that it is all said and done, i actual love it freestanding. it almost looks like a fireplace on that wall. with that being said, i think it would look fine with cabinets on both sides if you have the room. also, since the hood curves inward, i think it would look best to leave a little room between the hood and the cabinets so it does't feel too crowded....even if it is only 6 inches or so......very much like the picture lyno did for sdionnemoore sdionnemoore....i think i would keep the mantle and trim on the hood the same hickory color as your cabinets. i suppose you could do black but i think i would keep everything on the perimeter consistant.....that's just my preference though!!! the other thing i really loved about my inspiration picture was that the backsplash was only above the cooktop. it gives it more of a fireplace feel, and you can pick something that really makes a statement. but you could continue it under your cabinets if you prefer or use a different backsplash above the cooktop than the backsplash below the cabinets.

I'm getting ready to install the backsplash tile and it will be going up first then the rangehood and chimney. My reasoning, my sister remodeled and her GC installed her hood and then tile was applied up to the ceiling in a herringbone pattern, 2 months later the hood malfunctioned and research showed a defect in the electronics. The new hood that was selected didn't match the tile layout outline and the tile had to be taken down to just above the range, her nightmare continued when she learned the marble tile had been discontinued. I figure its easier to chip out the tiles containing the anchor mounting hardware and replace them, than a whole wall of marble tile. Having done many kitchen tile jobs if the wall is flat, the tile will be flat.

Hoods such as the VaH ARS that have significant filter packs and adequate blower performance can reduce odor and grease. We have a long running ARS thread here. https://www.houzz.com/discussions/2347276/vent-a-hood-ductless-ars-range-hood-update#n=65 Broan may also make an adequate assembly, but we haven't seen any review. More modest designs will be much more modest in filtering performance.
