draught. The flue must be adequately distanced from flammable or combustible materials by means of<br />
insulation or an air gap.<br />
It is forbidden to run it inside the piping of air feed systems or channels. It is also prohibited to make moving or fixed<br />
openings on the flue for the connection of other different devices.<br />

1) Flue in AISI 316 steel with double chamber insulated with material resistant up to<br />
400°C. Efficiency 100% excellent.<br />
2) Flue in refractory material with double insulated chamber and external covering in<br />
lightened concrete. Efficiency 100% excellent.<br />
3) Traditional flue in clay, square cross-section, with air gaps. Efficiency <strong>80</strong>%<br />
excellent.<br />
4) Avoid using flues with rectangular section having a ratio different from that shown in<br />
the drawing (MAX=A+1/2A). Efficiency 40% mediocre.<br />

The flue draught also depends on the suitability of the chimney cap.<br />
It is therefore indispensable that the outlet cross-section be twice the internal cross-section of the flue when making<br />
the chimney cap by hand. As it will always rise above the roof ridge, the chimney cap must also ensure exhaust even<br />
in the presence of wind. (see Picture 9)<br />
The chimney cap must meet the following requirements:<br />
• The internal cross-section must be equivalent to that of the chimney.<br />
• The useful outlet cross-section must be twice that of the internal cross-section of the flue.<br />
• It must be constructed in such a way as to impede the penetration of rain, snow, or any foreign body into the flue.<br />
• It must be easy to inspect for any maintenance and cleaning operations.<br />
