Soffit Ducting Kit
The soffit is probably the most common place to vent a rangehood from in New Zealand. Quite simply the rangehood outlet is connected to the outside with a length of ducting and a louvred grill, which is screwed to the soffit.
As always, the quality of ducting is important to ensure the rangehood performs as it should and that noise is kept to a minimum. Ducting that disrupts the airflow will cause noise and reduce performance. Ducting that prevents the back-draft flaps from rising properly will restrict the airflow, strain the fan motor and increase noise.
A soffit ducting kit will consist of 3m of semi-rigid ducting and a louvred outlet vent. It may also have a pair of ties but ducting tape is adequate to seal the duct ends to the rangehood and vent.
