Cut an opening in the floor and insert the sleeve (sleeve can be trimmed with a fine tooth saw to reduce the depth if required). Fasten the louvre to the sleeve through the pre-formed holes using the screws provided. Peel off the protective film.
Note: When installing in an uncarpeted floor the flange may be trimmed and the louvre ventilator screwed to the floor to maintain as flush a finish as possible.
Important: In areas where radon gas has been identified as a problem, ventilation shall not be taken from the space below ground floor level (e.g. using a floor vent), or interfere in any way with any remedial measures already in place to prevent radon gas entering the habitable part of the dwelling.
