The flue pipe is the “engine” of the stove. Whatever the type, it must be compatible with waste-gas temperature of 600 °C at least and resist to soot combustion. It must bear the label UNI TS 11278, duly filled in by the installer, well visible, and completed by the declaration of compliance in accordance to the law in force (D.P.R. n. 1391/70 e dal D.M. n. 37/2008).
The flue pipe installer must control that the pipe, made in lined refractory material or insulated metal, is perfectly sealed and provided with adequate protection particularly through the wooden structures of floors and roofs. Refractory rings and stainless steel skin must expand vertically up to the chimneys. |
