The hose goes straight up to the ceiling in the loft above bunk. You have to remove a wood panel to get to it. On mine the hose was connected to a metal fitting. That metal fitting was like the black plastic piece everyone is taking off. So i just trimmed it down so it did not stick up in the ceiling to block the air flow. Taped everything up good while I was in there too. That really helped with my air flow in the bunk room.
