Year 2 - Day 282

Ay carumba! The range hood is up but not without much crunching of brain cells, wringingof hands and of course the able help of Bob. Many challenges as usual. 1) our ceiling is only 7'6" so with the hood at the recommended 28" above the cooktop that left us with just over 14" to get the duct up, through a 90 degree turn and out the wall; 2) The center point for the range hood was right on a stud, a stud which happened to be the LH stud of a panned in stud bay that was a return for the HVAC which couldn't be violated; 3) The outer edge of the range hood chimney was about 3-1/2" from the center line and had a 5/8" flange that sat against the wall, this gave us an effective usuable space for the outgoing duct of approx. 3"; 4) The duct collar coming out of the range hood was 6" circular and centered on the range hood.
This picture shows the final solution: I explained my challenge to a local plumbing supply store (N&S Supply, Danbury, CT) and out of the many ducts they showed me we found a 90 degree elbow that was 6" round on one end and 6" oval on the other. This was like it was custom made for me! The vertical oval was 3" at it's widest section - just enough to go through the gap that we had. I had to shorten both the 6" round cone part and the 6" oval part to get it to turn a full 90 degrees in the 14" that we had to work with. I sheet metal screwed it and aluminum taped it to stop it breaking apart when we shoved it through the wall. I also extended the oval end so that it would extend all the way through the wall.











Here it is in all it's friggin' glory.










So today I just had to finish off the outside. As usual still not a stright forward job as the siding wasn't level so I filled it in with some siding offcuts turned the opposite way to the boards so that I got a flat surface so that the plastic cover would sit flush with the siding. I also had to customize the plastic duct vent as it was made for 6" round. After filling in teh gaps around the duct with insulating foam, I cut the duct extension into flanges so that it I could sheet metal screw it to the siding. I then aluminum taped over all screws and seams to fully seal the duct exit and then screwed the plastic cover to the wall and caulked the where it touched the wall. I have burnt more brain cells on this project than I did on moving the window but I thinkthe final result has been worth it.
