• The chimney flue must be sealed from fumes.

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 flammable materials with an air gap or with insulating materials.
Check the distance with the chimney manufacturer.

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 flue can be round (the best one) or square and the jointed sides must have

• The flue system must be placed on the roof.
• The chimney flue must be provided CE in accordance with EN 1443 regulation. Please find attached an

HEIGHT-DEPRESSION
The depression (draught) of a chimney flue depends also on its height. Check the depression with the values
provided at FEATURES page 38. Minimum height 3,5 meters.

MAINTENANCE
• The chimney flue must be cleaned, since the soot and unburnt oil deposits reduce its section so blocking the
draught. In great quantities they can flare up.
• The fumes extraction pipes (fumes conduit + chimney flue + 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 flue 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.
