FOREWORD
This chapter on the Smoke Flue has been produced in reference to the prescriptions of European regulations (EN13384 - EN1443 - EN1856
- EN1457).
The chapter provides indications for installing an efficient and correct smoke 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 chimney.
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 regulations in force.
SMOKE FLUE
The flue or chimney is of great importance for the proper operation of a solid fuel-burning heating appliance with natural draught, as
modern heating appliances have high efficiency with cooler flue gasses and consequently less draught, it is therefore essential that the
flue is built up to standard and always kept in perfect working order. A flue that serves a pellet/wood fuelled appliance must be at least
category T400 (or greater if the appliance requires, 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 in cement must be suitably lined. In both solutions there must be an inspection cap (AT) and/or inspection hatch (AP)
- FIG.1.
It is prohibited to connect more than one wood/pellet or any other type of appliance (vent cowling...) to the same flue.
The stove must be connected to a flue pipe or an internal or external vertical duct conforming to EN 1856-1-2 to suit the
appliance and types of fuels to be burnt – refer to detailed guidance in sections 2, 3 and 4 (ONLY FOR UK).
