How do you remove an existing flexible ducting hose that goes from the ventilation hood/fan above a stovetop to an outside wall? & then replace it?
We have a 60cm wide cooker hood (what it's called here in the UK) over our stovetop. There is a flexible hose 100mm in diameter that goes from the hood, directly up vertically through one cabinet & then bends 90 degrees to the left to run straight along the top of the cabinets to a hole in our outside wall.
We want to replace the hose part. We aren't completely sure how to take the existing one out & then be able to put the new one in cleanly because there is no mounting plate on the kitchen wall (on the inside). And we don't want to rip the existing one out only to find that we can't fit a new one in easily either.
As I said, there is no plate or fascia over the hole in the wall on the inside, but there is a plate on the exterior wall of the house that has 3 slats - they are closed when the hood is off, they open up when the hood is turned on. I believe its official name is: "External Wall Louvre Vent"
There is a metal band (& screw to tighten it) around the hose near where the hose enters the actual cooker hood (in the cabinet above the hood).
We bought the replacement flexible hose already so we're good to go there. & we know we'd need to take that metal band off & the fascia on the outside wall of the house, but we aren't sure if that's all we need to do. Is there anything else that needs to be done?
Has anyone ever done this before - particularly someone else living in the UK?
