5. FLUE<br />
Essential prerequisites for correct operation of the appliance:<br />
• The internal cross-section should preferably be circular.<br />
• The flue must be thermically insulated and waterproof and<br />
made of materials that are resistant to heat, combustion<br />
products, and any condensates.<br />
• It must be free of bottlenecks and be vertical with deviations no<br />
greater than 45°.<br />
• If the flue has already been used, it must be cleaned.<br />
• Respect the technical data provided in the instruction manual;<br />

If the flue has a square or rectangular section, the internal angles must<br />
be rounded with a radius of no less than 20 mm. For the rectangular<br />
section, the maximum ratio between the sides must be 1:5.<br />
A cross-section that is too small will cause a decrease in draught.<br />
We recommend a minimum height of 4 m.<br />
The following materials are prohibited, as they could jeopardise the<br />
correct operation of the appliance: asbestos cement, galvanised steel,<br />
internal surfaces that are rough and/or porous. Picture 6 shows some<br />
examples.<br />
The minimum cross-section must be 4 dm2 (for example: 20 x 20<br />
cm) for appliances with duct diameter less than 200 mm, or 6.25<br />
dm2 (for example: 25 x 25 cm) for appliances with diameter<br />
greater than 200 mm.<br />
1) Flue in AISI 316 steel with double<br />
chamber insulated with material<br />
resistent up to 400°C. Efficiency<br />
100% excellent.<br />
2) Flue in refractory material with<br />
double insulated chamber and<br />
external covering in lightened<br />
concrete. Efficiency 100%<br />
excellent.<br />
3) Traditional flue in clay, square<br />
cross-section, with air gaps.<br />
Efficiency 80% excellent.<br />
4) Avoid using flues with rectangular<br />
section having a ratio different<br />
from that shown in the drawing<br />
(MAX=A+1/2A). Efficiency 40%<br />
mediocre.<br />

(1) Connecting the flue to more than one<br />
appliance is not recommended. Each one should<br />
have its own flue.<br />
