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, hot wind.
•
The angle of the bend of the expansion pipe should not be less than 120º; 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.
•
After the installation, make sure that the cooker hood is level to avoid grease collection at on end.
•
Ensure the expansion pipe selected for installation complies with relevant standards and is fire
retardant.
