We just had it installed yesterday. Recommend that you get a print out of the specifications and the installation. From what I was able to read in Wayfare’s description section, we would be able to install the unit flush with the ceiling. And unfortunately, because I didn’t have printed specifications we had to drop down the unit a foot  from the ceiling. Not the inconspicuous flush mount unit and I was hoping for. According to my contractor, this was a very complicated unit to install. To be fair this is a relatively new category of range top hoods that are being offered. Pleased with the noise level, but have yet to cook with it. Read reviews from other previous purchasers, and a common statement was how small the remote controller was. Minuscule is more appropriate for the slim silhouette 1 1/2 x 3“ controllers. Hope this was helpful.
