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 flexible ducting as this
has a significant negative impact on airflow and
noise due to turbulence
• caused by the ribs. Instead consider using semi-
rigid or rigid duct.
• Avoid using a narrower duct than specified as
this will reduce airflow; 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 specified 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 five 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.).
