@Randys Construction: once you have selected the gas range you'd like to use, please feel free to take a look at our website (www.FuturoFuturo.com), or give us a shout (phone or E-mail), and we can provide advice on choosing the range hood.

@bubblyjock: thank you for your kind compliments! You're absolutely right about how Houzz should work - this is the age of communication, companies must be engaged with the market, and be aware of their potential customers' concerns and wishes.

Now, on to your question about sloped/vaulted ceilings...

You will not find an "off-the-shelf" island range hood that can accommodate any ceiling other than perfectly flat & level. Unless you're going to have a metal fabricator make a custom chimney for you (time & $$$), this issue would need to be solved not at the hood, but at the ceiling.

To accommodate a sloped/cathedral ceiling, simply build a soffit. The soffit only needs to be large enough to accommodate the vertical chimney of the hood (13" x 10.5" on most of our models), but it can be made bigger for visual effect, or to incorporate lighting or other design features. An example of a large soffit is attached below.

A soffit is very easy to build, it typically involves only beams, sheetrock, and paint - and it's much cheaper than a custom chimney. Plus, it can provide space for the ducting, as well as additional lighting or decorative accents.

Here's a page on our website that provides some examples of different types of soffit boxes: http://www.futurofuturo.com/rangehood-FAQ-sloped-ceiling.php
