Use smoke ducts that are able to withstand the unit operating temperatures (min. T400).
The use of flexible metal hoses made
of fibre cement or aluminium is forbidden. For direction changes, we always recommend the use of a T fitting
with an
inspection cap ensuring easy access to clean the pipes. Always ensure that the inspection cap is put back in place and sealed hermetically
with the relevant seal intact after cleaning.
It is prohibited to connect more than one appliance to the same smoke duct, or the discharge from hoods above it. It is forbidden to extract
the combustion products directly through the wall, whether into indoor spaces or outdoors.
The smoke duct must be installed observing the safety distances from flammable materials as specified on its rating plate (e.g. G400=
400 mm).
