An extractor fan may only be used in the same room as this appliance, or in any
area from which ventilation for the appliance is taken, if it does not affect the safe

this manual. If the fan is likely to affect the appliance, the appliance must not be
installed unless the fan is permanently disconnected.

The minimum height from the base of the fireplace opening to the underside of
any shelf made from wood or other combustible materials is shown below: -
•
For a shelf up to 150mm deep
Minimum height = 700mm.
•
For a shelf deeper than 150mm
Minimum height = 700mm + 12.5mm for every 25mm depth over 150mm.
(See graph 1).

If the appliance is to be fitted against a wall with combustible cladding, the
cladding must be removed from the area covered by the fascia. The cladding must also

template to mark the area for combustible cladding removal and that this area is
increased by at least 2mm all round. If the cladding projects forward from the fixing
