Do your research. Chimney dimensions are rounded up. This woul dnot have worked for my 7.5' ceiling. I had to purchase a short chimney which had the correct dimensions whereas this was rounded up to 10.8 and 11.8 instead of 10.75 x 11.75. Verified info with Z-line and Wayfair confirmed as well about a week later but the info on the Wayfair site has not been updated. It's installed and works and looks beautifully for the two days it's been installed. And the controls are on both sides which is a bonus.
