6. GENERAL RULES FOR THE REALIZATION OF THE FLUE
Here are illustrated a few simple yet important rules to follow for the safe construction of the flue (for further
information, please read the UNI 10683 regulation)
• The safe and correct functioning of the pellet stove is dependant on the connection to a single and
independent flue. No other fireplace, stove, boiler, aspiring hoods etc... are to be connected to the same
flue (see fig.3).
• This machine needs to expel products resulting from combustion via a vertical flue that has a suction
pressure between 6 and 10 Pa, in order to constantly guarantee the expulsion of smoke, even with the
absence of electric power or adverse conditions.
• The part of the flue that extrudes from the roof or remains in external contact must be covered with tiles or at
least well insulated.
• The stack must be wind resistant, have an internal section that is equal to that of the flue, a useful section at
least twice the size of the flue, and prevent entering of rain.
• Any other building parts, plants or other obstacles that are higher than the roof must be positioned at least
3m away from the flue.(see fig.4).
• Whenever two flues with parallel exits are used, it is advisable to lift the wind resistant flue (see fig. 5).
 The flue section must be uniform, with smooth surfaces that do not narrow down, and the curves must be
regulated, without discontinuity.
 It is advisable that the smoke conduct has a solid material and eventual condensation collecting box,
positioned under the smoke conduct intake, so that it is easily accessible and can be inspected from the
airtight door.
