Britannia 70CM, User Instructions

WARNING - THIS APPLIANCE  MUST BE EARTHED 

Important: 

The wires in this mains lead are

coloured in accordance with the following code:- 

Green/Yellow = Earth, Blue = Neutral, Brown = Live 
 

As the colours of the wires in the mains lead of this appliance may not correspond with the 
coloured markings identifying the terminals in your spur box, proceed as follows: 
The wire which is coloured green and yellow must be connected to the terminal which is marked 
with the letter ‘E’ or by the earth symbol or coloured green or green and yellow. The wire which is 
coloured blue must be connected to the terminal which is marked with the letter ‘N’ or coloured 
black. The wire which is coloured brown must be connected to the terminal which is marked with 
the letter ‘L’ or coloured red. 

Height above Hotplates 
 

For best performance we suggest that the hood is installed at a distance between 65cm to75cm 
from the hotplate surface. Under no circumstances should the hood be installed lower than 65cm 
above the hotplate surface. 
 
 

Ducting out / Filtering 

The hood can be used as a filtering version or as a ducted version. It is always preferable to 
install the hood as a ducted version i.e. duct to an outside wall. If this is not practical, charcoal 
filters can be fitted. In the filtering mode the air drawn in is purified as it passes through the 
charcoal filters, the air is then recycled back into the kitchen. It is realistic to assume that using a 
hood in filtering mode will circulate 30% less air than by ducting out. Charcoal filters are an 
optional extra and will require replacing after 120 hours of use or at least every 6 months. 
Charcoal filters are not required if you duct out. If the hood is used as a filtering version, please 
note that the filters will help reduce cooking odours but will not reduce steam or condensation. If 
you wish to reduce steam, condensation and cooking odours then you must duct out.  

We strongly recommend that the hood is only used as a filtering version if it is impossible to duct 
out. 
 
 

Ducting Information

 
To obtain the best possible extraction performance use 150mm diameter ducting. Wherever 
possible utilise rigid circular pipe or “Mega duct” ducting. Both types are available via your 
Britannia dealer. Do not use expanding concertina type ducting as this is not smooth on the 
interior and can cause air flow restrictions. Do not use ducting that has a smaller diameter than 
150mm as this will reduce extraction rates and can increase noise levels. Please note ducting kits 
and ducting components are optional accessories and have to be ordered. They are not supplied 
with the hood.
