• The chimney ue must be sealed from fumes.
• It must have a vertical run without narrowing. It must be realized with fume and condensation resistant
materials with thermal insulation and able to last against usual mechanical stresses.
It must be insulated to avoid condensation and to reduce fume cooling effects.
• The stove must be spaced out from fuels or ammable materials with an air gap or with insulating materials.
Check the distance with the chimney manufacturer.
• The chimney entrance must be placed in the same room where the appliance is installed or otherwise in
the adjacent room and it must be provided with a solid and condensation collection chamber under the
entrance, accessible through the sealed metal gate.
• Auxiliary exhaust fans cannot be installed neither along the chimney nor on the chimney pot.
• The inner section of the chimney ue can be round (the best one) or square and the jointed sides must have
a minimum radius of 20 mm.
• The section dimension must be minimum Ø120 mm and maximum Ø180 mm.
• Made the efciency of the chimney ue overhauled by an expert stove-repairer and if necessary cover the
chimney ue with materials in compliance with current regulations.
• The ue system must be placed on the roof.
• The chimney ue must be provided CE in accordance with EN 1443 regulation. Please nd attached an
example of label:

8.4 HEIGHT-DEPRESSION
The depression (draught) of a chimney ue depends also on its height. Check the depression with the values
provided at FEATURES page 34. Minimum height 3,5 meters.
8.5 MAINTENANCE
• The chimney ue must be cleaned, since the soot and unburnt oil deposits reduce its section so blocking the
draught. In great quantities they can are up.
• The fumes extraction pipes (fumes conduit + chimney ue + chimney pot) must always be cleaned, scrubbed
and checked by an expert stove-repairer, in compliance with current regulations, with the instructions of the
stove-manufacturer and the directives of your insurance company.
• In case of doubts, please follow the most restrictive regulations.
• Have your chimney ue and chimney pot checked and cleaned by an expert chimney sweep at least once
a week. The chimney sweep has to release a written declaration about the security of the system.
• Not cleaning compromise safety.
