CONNECTIONS
Ducted mode air exhaust system
Caution: To reduce the risk of fire, use metal
ductwork is preferred.
1. Decide where the ductwork will run
between the hood and the outside.
2. A straight, short duct run will allow the hood
to perform most efficiently.
3. Long duct runs, elbows, and transitions will
reduce the performance of the hood. Use
as few of them as possible. Larger ducting
may be required for best performance with longer duct runs.
4. Attach an adequate length of
φ
150mm round duct to the air outlet adapter.
5. The air must not be discharge into a flue that is used for exhausting fumes from
appliances burning gas or other fuels" "Regulations concerning the discharge of
air have to be fulfilled.
6. Install a roof/wall cap. Connect round metal ductwork to cap and work back
towards hood location. Use duct tape to seal the joints between ductwork
sections.
