Dear All,
I have an Elica Plaza cooker hood which has been installed for around 5 years. It currently vents through the kitchen wall to the open air via 150mm ducting.
I am considering re-routing the ducting due to fitment of a new extension. To allow this the cooker hood ducting will need diverting to allow it to vent to the open air via the soffit. Unfortunately, the soffit is small so cannot accommodate the fitment of a 150mm grille. I am therefore considering fitment of a 150mm to 100mm reducer in the last 300mm of ventilation before the soffit. 95% of the ducting would be in 150mm and the last 5% in 100mm.
I would appreciate your thoughts on whether this would put any stress on the fan and also whether there would be any real measurable reduction in performance.
Kind Regards
Paul
