CONNECTION TO THE FLUE
The connection between the flue and the appliance must be via a smoke duct that conforms to EN 1856-2. The connecting section must
extend no more than 4 m horizontally, with a minimum slope of 3% and with a maximum of 3 90% bends (accessible for inspection - do
not count the T fitting at the appliance outlet).

Use smoke ducts with a diameter of 80mm or 100mm depending on the type of system, with silicone gaskets or similar gaskets that can
withstand the high operating temperatures of the appliance (min. T200 class P1).
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
allowing easy access for cleaning the tubes. 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 at a minimum distance of 400 mm from flammable or heat-sensitive structures.
