FOREWORD
The Chimney Flue chapter has been drawn up with reference to the provisions of European Standards (EN13384 - EN1443 - EN1856 -
EN1457).
The chapter provides indications for installing an efficient and correct flue but is under no circumstances to substitute the regulations in
force, which the qualified technician must be in possession of. Check with local authorities whether there are any restrictive regulations in
force regarding the intake of air for combustion, the smoke extraction system, the flue or the chimneypot.
The company declines all liability relating to the poor functioning of the boiler if this is due to the use of an insufficiently sized flue in
violation of the Standards in force.
FLUE
Have the efficiency of the flue checked by an authorised technician.
The flue or chimney is vital to the correct functioning of a forced draft solid fuel heating appliance, given that boilers with high performance
have cooler fumes with consequently weaker draft and the possible formation of condensation.
It is therefore essential that the flue meets all construction standards and is always maintained in perfect condition.
A flue that serves a pellet/wood fuelled appliance must be at least category T400 (or greater if the appliance requires so) and resistant to
soot fires. Smoke must be extracted through a single flue made of insulated steel (A) or an existing flue that complies with the intended
use (B).
A simple air shaft made of cement must be suitably lined. In either case, ensure to include an inspection cap (AT) or inspection door (AP)
and a suitable device for collecting condensation - FIG.1.
It is prohibited to connect more than one wood/pellet (*) or any other type of appliance (vent cowling...) to the same flue.
(*) unless there are national derogations (for instance in Germany), which under suitable conditions allow for the installation of several
appliances in the same fireplace. In any case, strictly follow the product/installation requirements of the relative regulations/legislation
in force in that country
.
