INSTALLING THE COOKER HOOD
Extraction (Ducted)
The cooker hood is more effective when installed in the extraction mode (ducted to the outside). Venting kits may be purchased through your retailer or DIY store or using the enclosed form, and must be evacuated through an outside vent of �125 (5ins) or �150mm (6ins). The ducting used must be manufactured from fire retardent material conforming to the relevant British Standard or DIN 4102-B1. When the cooker hood is ducted to the outside the charcoal filter must be removed.

Fitting the Ducting
� Fit the �150mm (6ins) ducting to the spigot on top of the hood body as illustrated. When using �125mm (5ins) ducting fit item 9 and 10 on to the spigot on the top of the hood body as illustrated. For the best performance use the shortest possible run of ducting and we recommend the use of rigid pipe in preference to flexible hose as this will improve the flow of air while reducing turbulence, which causes causes noise and a loss of performance. If the room where the cooker hood is to be used contains a fuel burning appliance such as a central heating boiler, then its flue must be be of the room sealed or balanced flue type. If other types of flue or appliances are fitted ensure that there is an adequate supply of air to the room. The cooker ducting when fitted in the evacuation mode must never be connected to central heating flues, radiators or water heaters.

Recirculation Mode
The cooker hood is supplied specified for use in the recirculation mode, with the charcoal filter fitted. In the recirculation mode contaminated air is passed through the charcoal filter to be purified and recirculated into the kitchen through the grille outlets on either side of the chimney.
