Try to plan Britannia cooker hoods
onto an outside wall in the kitchen if this is at all possible.
By doing this, you will minimise the length of the ducting and
maximise the hood performance. General guidelines - All Britannia
cooker hoods have high performance extraction rates, therefore using
the correct size ducting is of paramount importance. The majority
of Britannia cooker hoods have outlets to accept 150mm diameter ducting.
Do not be tempted to use reducers and fit 125mm or 100mm ducting
as this will dramatically reduce performance and increase noise
levels. Do not use concertina type expanding 150mm ducting.
When planning your ducting run try to keep the number of bends
to a minimum as this will also help maximise the hood performance.
We suggest that you always utilise rigid circular ducting or
'Mega duct' to optimise performance, (please note the twin motor
canopy hood model CK2000 is designed to take 200mm diameter
ducting due to the exceptional high power). Note that any ducting
used must not be connected to any existing ventilation or flue
system that is being used for any other purpose.
Very Important : Britannia Cooker Hoods over BBQs
If you intend to use Britannia cooker hoods over range cookers with a barbeque, chef top,
or if you intend to use a griddle, then you must duct out.
We strongly recommend that any cooker with a barbeque is always
sited on an outside wall of the kitchen so as to minimise
the ducting run and maximise hood performance. Hood model
K274L is specifically designed for use over the 90cm cooker
with barbeque,

Cooker Hoods Height above hotplates
Ideally Britannia chimney cooker
hoods should be positioned between 650mm to 750mm above the
Britannia hotplate surface. Note that the chimney hood must
not be positioned lower than 650mm. If you are using a Britannia
back panel with ladle rack the height is pre-determined at
660mm. Ideally the chimney hood should be positioned between
650mm to 750mm above the hotplate surface. Note that the chimney
hood must not be positioned lower than 650mm. If you are using
a back panel with ladle rack the height is pre-determined
at 660mm.
Chimney Cooker Hoods Telescopic flues
All the wall mounted chimney cooker hoods models (detailed on pages 68 to 71) and the corner chimney hood have telescopic flues, which adjust to suit most room heights. The telescopic flue is made up of a lower and upper section. The lower section houses the motor. The upper section conceals the ducting, it is open at the rear so ducting can be turned through 90 degrees to go out through the rear wall. Alternatively the ducting can be run out of the top of the upper flue section and through the ceiling. The remaining wall mounted chimney hood models have the motor housed in the base section of the hood and the telescopic flue section hides the ducting. |
