2.6 Extractor fans or cooker hoods must not be placed in the

same room or space as this can cause the appliance to emit

fumes into the room.

appliances.

2.8 The need for additional ventilation may also be identified

during the commissioning procedure and should be provided

if needed.

An inadequate air supply to the room is potentially

fitting of the appliance until they have been rectified.

where they are unlikely to be become blocked.

2.4 If vents open into adjoining rooms or spaces there must be an

air vent of at least the same size direct to the outside.
