Installing your Cooker Hood
RECIRCULATION:
The chimney hood is supplied specified for installation in the extraction mode. To convert to recirculation it will be necessary to obtain the optional pack of two carbon filters.
In the recirculation mode, contaminated air enters the chimney hood and passes through the grease filters and carbon filters and then out into the kitchen through two grilles, at either side of the lower chimney.
To convert the chimney hood to recirculation proceed as follows:
1.To fit the carbon filters, open the metal grease filters. Place one filter over the inlet grille at either end of the fan housing and twist into position (Fig.2).
Fig.2
2.Fit the recirculation spigot over the round outlet on top of the canopy, whilst pressing down on the spigot (Fig.3).
EXTRACTION:
Ducting Fitting:
The chimney hood can be ducted to the out- side, using either rigid or flexible ducting of 100mm, 120mm or 150mm. the choice of ducting is left to the discretion of the installer, however, the best performance will be obtained by using 150mm of rigid ducting. Where flexible ducting is fitted it should not be turned through very tight bends as this could impair the performance of the hood. The ducting must be manufactured from fire retardant material conforming to the relevant British Standard or DIN
Where the 125mm ducting is used, it will be necessary to install the reduction flange and 125 ÷ 125mm ducting collar over the air out- let in the top of the canopy (Fig.4).

The installer should provide suitable ducting and sealing tape for the installation.
The (optional) carbon filter is not required when the hood is installed in the ducting mode.

NOTE: The two venting grilles must not be fitted into the chimney stack until the chimney stack has been installed onto the wall above the canopy.
