HINTS FOR EXHAUST DUCT INSTALLATION
The following rules must be strictly followed to obtain optimal air extraction:
● Keep exhaust duct short and straight
● Do not reduce the size or restrict exhaust duct
● When using flexible duct always install the duct pulled taut to minimize pressure loss
● Failure to observe these basic instructions will reduce the performance and increase noise levels of
the cooker hood.
● Any installation work must be carried out by a qualified electrician or competent person.
● Do not connect the ducting system of the hood to any existing ventilation system which is being used
for any other appliance ,such as warmer tube, gas tube , hot wind tube.
● The angle of the bend of the ventilation pipe should not be less than 120º; you must direct the pipe

wall.
● After the installation ,make sure that the cooker hood is level to avoid grease collection at on end
