Termocamino 650 - 800
5. FLUE
Essential prerequisites for correct operation of the appliance:
•
The internal cross-section should preferably be circular.
•
The flue must be thermically insulated and waterproof and
made of materials that are resistant to heat, combustion
products, and any condensates.
•
It must be free of bottlenecks and be vertical with deviations no
greater than 45° .
•
If the flue has already been used, it must be cleaned.
•
Respect the technical data provided in the instruction manual;
If the flue has a square or rectangular section, the internal angles must
be rounded with a radius of no less than 20 mm. For the rectangular
section, the maximum ratio between the sides must be 1:5.
A cross-section that is too small will cause a decrease in draught.
We recommend a minimum height of 4 m.
The following materials are prohibited, as they could jeopardise the
correct operation of the appliance: asbestos cement, galvanised steel,
internal surfaces that are rough and/or porous. Picture 6 shows some
examples.
The minimum cross-section must be 4 dm2 (for example: 20 x 20
cm) for appliances with duct diameter less than 200 mm, or 6.25
dm2 (for example: 25 x 25 cm) for appliances with diameter
greater than 200 mm.
