kitchen extractor fan ducting

by Stob » Fri Jun 27, 2008 4:20 pm

Does anyone know if there is a maximum recomended length for 4" ducting from a kitchen extracting fan going to the outside?
I am thinking of re-locating my kitchen and the new position of the extractor would be about 4-5m from the nearest outside wall.
