How to install a Schweigen Silent Rangehood

All Schweigen silent rangehoods come with Schweigen SteelFlex™ high performance safety ducting at no extra cost.

Good design practice would always see a fire-rated ducting system extend to the house exterior, rather than to the ceiling cavity. When a rangehood is ducted only into the ceiling space, the collection of humidity and grease can present very real health issues and fire hazards. Over time, the back pressure will also impact the longevity and performance of the rangehood motor.

Different Australian states have varying legislative requirements for the installation of rangehood ducting. Some will insist on ducting being vented externally (i.e. not in to the ceiling cavity); others will not. It is imperative that you check with your state building authority and/or private certifier to confirm their position.
