CHIMNEY FLUE CONNECTION
Your pellet stove works through a fume draught forced by a fan. It is obligatory to check that all pipes are realized in compliance
with the following regulation on material selection: EN 1856-1, EN 1856-2 e UNI/TS 11278. All must be effected by specialized
personnel or companies as provided by UNI 10683:2012.
• The connection between the appliance and the chimney flue should be short in order to favor the draught and to avoid con-
densation in the pipes.
• The fume conduit should be equivalent or longer than the outlet joint ones (Ø 80 mm).
• Some stove models are endowed with a lateral and/or back exhaust. Check that the unused exhaust is sealed with the plug
given with standard equipment.

• Use a plate pipe for stoves of Ø80 mm or Ø100 mm depending on the type of system and with silicone gaskets.
• It is forbidden to use metal, fibre cement or aluminium flexible pipes.
• For change of direction it is obligatory always to use a union (with angle > 90°) with inspection plug which enables an easy
periodic cleaning of the pipes.
• Please assure you that after the cleaning the inspection plugs are sealed with its efficient gasket.
• It is forbidden to exhaust flue gases directly from the wall towards the outside and closed spaces also at open top.
• The fume conduit must be placed at a distance of minimum 500 mm from flammable or heat-susceptible components.
• 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.
