I have a new (second hand) Omega rangehood that i am installing in my new (second hand) kitchen. I am unsure what type of ducting i need for the rangehood. I dont have the original instruction booklet, nor can i find it on the Omega website (probably too old).
I am ducting it up an old chimney that used to service the copper in the laundry (a long time ago).
My specific questions are:
1. Can i use standard PVC pipe, or do i need something special?
2. What diameter pipe do i need. Outlet from unit is 125mm, but cannot fit 125 mm pipe up chimney.
3. I was planning to just duct it into the bottom of the chimney and let it do its own thing from there (rather than duct all the way up to the top of the chimney). Is this OK?
Any advice welcome.
thanks
Nicko
