cooker hood conversion

[ugjointer]

I would like to convert my Firenzi cooker hood from recycling to ducted extraction via a 100mm flat ducting to outside wall.Do I remove the circular carbon filter and the flat filters from the unit when I convert the hood.Also would the Firenzi hood be powerful enough to extract the odours down one and a half mtres of ducting.The hood is a cheapo that was given away with a Magnet trade kitchen.

The carbon filter goes in the bin but the filters that are just inside of the grille remain. There may be adjustable flaps inside that cover either the back or top outlet, depending on which way you want the fumes to exit. The hood should perform fine over that short length of ducting. John
