Futuro Futuro Kitchen Range Hoods "Everyone" is wrong. The purpose of the vertical chimney cover is to conceal the blower motor, mounting bracket/hooks, and the duct. If the duct is angled into the wall, then the chimney only needs to be high enough to cover the duct.

Once the chimney is high enough to cover the "mechanicals" - you can leave it at any height you like past that. Make it proportional to the width of the hood, or match its height to the height of cabinets / window frame / other elements.

Here are a few examples of wall-mount hoods with chimneys that do not reach the ceiling:

Carm Longo - The Kitchen Planners Great question!!!

As the popularity of having an island continues to grow....the rule to keep in mind these days....is that there has to be at least one table in the home. It is no longer necessary to have both a kitchen table and an island....as long as there is a dining room area you can eliminate your kitchen table. Now in saying that...you would want to fit an island that can accommodate at least 4 people....the same minimum number as you would have if there was a table in the kitchen. When placing chairs, you want at least 2' in length for every chair on one side, and 42" of space to move behind the chairs when backing up against a wall! 36"-42" is acceptable space in front or on the side of an island if there are no chairs or countertop overhang. The more space the better especially if you are opening a dishwasher or oven!

Carm Longo - The Kitchen Planners I just saw now how old the question was....but still it is a great question!!!
