Installation with flexible ducting
Where flexible ducting is used the diameter must be
maintained with the minimum radius of a bend equal to
the diameter of the ducting. It is good ventilation
practice that the ducting is extended to 90% of its
possible length in order to maintain the best possible
airflow. Ensure that flexible duct connections are not
over tightened to the fan outlet spigot. To maximise
airflow rigid ducting should be used where possible.
The fan and ducting should be installed in accordance
with the requirements of the Domestic Ventilation
Compliance Guide, part of the Building Regulations.

Recommended Best Practice
The Building Regulations 2010, Statutory Instrument
Part 9, paragraph 42, imposes a requirement that
testing and reporting of mechanical ventilation
performance is conducted in accordance with an
approved procedure.
Compliance with this requirement by an assessed and
registered 'Competent Person' should follow a 'Best
Practice' process and adopt air flow measurement,
Method A – The Unconditional Method – using a
suitable UKAS certified measuring instrument.
Generically referred to as a 'Zero Pressure Air Flow
Meter' or 'Powered Flow Meter'.
Further information on this method is detailed in
NHBC Building Regulations Guidance Note G272a
10/13 and BSRIA 'A Guide to Measuring air flow rates'
document BG46/2015
