A:Answer Go to Broan website, or just search: Broan BKDEG130WW Sahale and go to the Broan website. All of the specs, installation pdf and videos are there. We are installing ours 12/29/19. Got everything out of box, removed the knockouts required for our type of installation. We are replacing a round vertically ducted 30" range hood that is ancient but made by the same company under their old name Mercury.
We are hoping when we remove the old one, we will logically see how the damper is installed.
Get metal foil duct tape also.
