The rangehood can be installed to operate with the exhaust air ducted externally from the kitchen, or installed to operate
in recirculation mode with the exhaust air recirculating within the kitchen.
Ducted externally
For an externally ducted installation it is recommended that 150 mm diameter, rigid or semi-rigid ducting is used. This
will require a 160 mm (min) round hole in the ceiling or wall. Care should be taken to position the hole correctly.
For optimal efficiency use the shortest and straightest duct route possible and use rigid or semi-rigid ducting for reduced
noise and increased airflow. Flexible metal ducting should only be used as a last resort (ie in difficult installations) and if
used ensure that it is straight and smooth and extended as much as possible.
Recirculation mode
To enable the product to operate with the air recirculating within the kitchen, please purchase a recirculation diverter and
carbon filters (refer to the ‘
Parts and accessories
’ section). The recirculation diverter is installed after a short length of
ducting and is required to channel the air out the side vents at the top of the chimney and the carbon filters are required
to remove odours.
A ducting hole is not required in the wall or ceiling if the rangehood is installed to operate in
recirculation mode.
