Hints for exhaust duct installation
The following rules must be strictly followed to obtain optimal air extraction:
•
Keep expansion pipe short and straight.
•
Do not reduce the size or restrict expansion pipe.
•
When using expansion pipe always install the pipe 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 or hot
wind tube.
•
The angle of the bend of the expansion pipe should not be less than 120°. You must
direct the pipe horizontally, or, alternatively, the pipe should go up from the initial
point and should be led to an outer wall.
•
Ensure the expansion pipe selected for installation complies with relevant standards
and is fire retardant.
• After the installation, make sure that the cooker hood is level to avoid grease
collection at on end.
