Fitting Ducting To Lamona Extractor

[80's Owl]

I currently have a Lamona extract unit built into a kitchen cupboard above the hob that's using charcoal filters, I've decided to extract it outside and have drilled the relevant holes to do so, the extractor has a black plastic 150mm outlet on top, I will be using 100mm flexible ducting, for the reducing kit do I need a one piece kit (150 - 100mm) or will I need one piece on top of the extractor and a second on the end of the ducting?

Most electrical wholesalers will have an adapter for under a tenner
