Installation Instructions

Prior to Installing the Rangehood
Before beginning the installation of your rangehood,
consider your ducting method.
This rangehood has been supplied with expandable plastic
ducting, however for maximum performance we recommend
installing with rigid or semi rigid ducting. Use cable ties or
suitable duct tape to secure the flexible pipe or ducting to
the rangehood duct outlet.
Recirculating Installation
We recommend ducting your rangehood wherever possible,
for the maximum performance, however this rangehood can
be operated in recirculating mode. You will need to purchase
the relevant Carbon Filter accessory which is available for
purchase from our After Sales Service Team.

Ducted Installation
WARNING: All ducting must be fire retardant.
Depending on your situation, there are multiple options
for ducting your rangehood, as follows:
• Straight up through your tiled or metal roof, using a roof
cowl (not supplied with the rangehood).
• Into your ceiling cavity (where compliant with local and
national building regulations/codes. Seek approval
from the relevant authority or building inspector where
necessary.
• Into your ceiling cavity and then vented to the atmosphere
through your eaves, using no more than 2 × 90 degree
bends within the ducting run.
• Through your wall.
IMPORTANT: Ducting can have a major effect on your
rangehoods performance. The following tips outline how to
correctly duct your rangehood.
• Always use the correct size ducting. This rangehood is
designed for use with 150mm ducting to achieve optimum
airflow performance and minimised noise.
• For maximum performance use semi rigid or rigid ducting
• Always use non-flammable ducting
• Always duct to the outside atmosphere, unless your local
building codes and regulations permit otherwise
• Where using flexible ducting, always install the ducting
pulled taut to minimize pressure loss, and cut any excess
ducting off.
• Where possible, avoid using 90 degree bends and in their
place use multiple 45 degree bends.
• Keep your total length of ducting to the shortest length
possible.
• Ensure there are no kinks in your ducting.
• Use cylindrical ducting whenever possible
