Exhaust ducting and connections
Use smooth or flexible pipework made
from approved non-flammable
materials for exhaust ducting.
To achieve the most efficient air
extraction and quietest noise levels,
consider the following:
– The diameter of the ductwork should
not be less than 8" (203 mm) with
DRIB/DREB XL and 10" (254 mm)
with DRIB/DREB XXL.
– If flat ducting is used, the cross
section must not be smaller than the
cross section of the ventilation
– The ducting should be as short and
straight as possible.
– Use ductwork with a wide radius.
– The exhaust duct must not be bent
– Make sure all connections are
– Where the ductwork is horizontal, it
must slope away from the hood at
