Wood burning stove in a shed

by Kev

Hi,
I have a summer house/bar in my garden I have just extended it and now want to put a wood burner in but am a little worried about the wooden walls,it will be sat on a stone floor so that's not an issue just the fact of installing the flue through the wooden frame.

I would if possible like to put the flue through the wall rather than the roof what sort would I require(height etc.) the outside of the walls are featheredge boards and the inside will be timber cladding,any help and advice would be appreciated.

Cheers

Kev
