TECHNICAL FEATURES

LEGEND
• The chimney flue 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 flammable 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.
• The inner section of the chimney flue 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 Ø150 mm and maximum Ø240 mm.
• Made the efficiency of the chimney flue overhauled by an expert stove-repairer and if necessary cover the
chimney flue with materials in compliance with current regulations.
• 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
example of label:

HEIGHT-DEPRESSION

• The depression (draught) of a chimney flue depends also on its height. Minimum height 3,5 meters.
• Installations with the exhaust at the back make flue gas evacuation very difficult.
• For installations with the exhaust at the back, we advise round AISI 316 flues with double insulated chamber.
• The horizontal duct connecting the stub pipe to the flue must be no longer than 30 cm.
• Check the depression with the values provided at FEATURES page 35.
