3.2 Ceiling Diffuser Installation
3.2.1 Ceiling Diffuser Location
The diffuser has a unique air throw pattern and it is essential that it is
located correctly in the central hallway in single storey properties or in
the ceiling of the top floor landing on 2 or more storey dwellings. The
diffuser discharges air evenly in all directions along the underside of the
ceiling.
SMOKE ALARMS -It is also important to ensure that the diffuser is
NOT placed within 1 metre of a smoke alarm.
Where a floor/room is more than 4.5m tall, the fan unit must be
fitted with a 3 storey aluminium diffuser and requirements in
section 5.2 followed.
If the diffuser cannot be repositioned, two sides of the diffuser must
be closed off using the air dams supplied to encourage the air through
the remaining open sides that faces at least 1.5 metres of unobstructed
area away from the smoke alarm sensor.
