RANGE HOODS
HOOD DUCTING GUIDE
Here are some important points to consider when choosing and/or installing a range hood:
• An externally ducted range hood will generally outperform a recirculating range hood.
• We discourage the use of exible ducting as this has a signicant negative impact on airow and noise due to turbulence
• caused by the ribs. Instead consider using semi-rigid or rigid duct.
• Avoid using a narrower duct than specied as this will reduce airow; the best performance is obtained when the range hood is
installed with a short duct with minimal bends.
• To determine the required clearance between the cooktop and the range hood always consult the installation manual for both
the range hood and cooktop. The required clearance is the greater of the distance specied in either manual (and a minimum of
600mm between the highest point of the highest burner for gas cooktops).
• Five metres is the recommended maximum length for ducting (see diagram 1.). When the ducting exceeds ve metres in length
the installation of a TD500 or TD350 in-line motor is required, which must be placed one metre from the external vent (see
diagram 2.).
