INSTALLATION INSTRUCTIONS
EN
WARNING!
To reduce the risk of fire, use only metal ductwork. Do not use flexible plastic ducting.
CAUTION!
To reduce risk of fire and to properly exhaust air, be sure to duct air outside –
do not vent exhaust air into spaces within walls or ceilings or into attics, crawl spaces,
or garages.
Venting options
Attention should be given to ensure that any applicable regulations concerning the
discharge of exhaust air are fulfilled.
The ventilation hood can be installed to operate with the exhaust air ducted
externally from the kitchen, or installed to operate with the exhaust air recirculating
within the kitchen.
Ducted
For ducted installation it is recommended that 6" (152 mm) diameter, rigid or
semi-rigid ducting is used. This will require a 6 5/ 1 6" (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.
Recirculating
To enable the product to operate with the air recirculating, purchase a recirculation
diverter and carbon filters (refer to the 'Parts and accessories' section). This recirculation
diverter is required to channel the air out the side vents at the top of the chimney and
the carbon filters are required to remove odors.
Note: a ducting hole is not required in the wall or ceiling if the ventilation hood is
installed to operate with exhaust air recirculating.
