Method 2: Extraction through
an outside wall
The fan draws cooking fumes through
the washable grease filter into the
underside of the hood, then the fumes
are expelled through a duct or directly
through an outside wall.

Assembly
1. Remove the grease filters.
2. Remove the carbon filter (if
supplied) and discard, as this is
not required when installing the
cooker hood as an extractor fan.
3. Connect the discharging pipe to
the ducting outlet adaptor, and
route the pipe through a 130 mm
hole in the rear wall.
Wall vent kit and ducting
•
For connecting the hood outlet
adaptor to the outside wall, we
recommend that a wall vent kit is
purchased from your supplier or
local hardware store.
•
Use a 125 mm diameter ducting
kit and connect to the ducting
outlet adaptor.
•
Horizontal duct runs should be
avoided. A slope of 5˚ or more
upwards from the hood to the wall
outlet will assist the flow of air.
•
The ducting pipe and any connecting
pieces should be coupled to the
preceding piece by pushing into
and never over it - the upper part
must be fitted over the lower part.
•
The outlet from the hood must not
be ducted into a wall cavity,
through a ventilator shaft or
through a chimney. It must not be
ducted through a flue used by a
non-electrically powered appliance.
•
Adequate ventilation must be
provided if a cooker hood extracts
fumes from the room at the same
time as an appliance powered by
a fuel other than electricity (such
as a gas appliance) is operated.
The extractor hood removes air
from the room which the burner is
dependant on for combustion.
