Try to avoid too many curves and horizontal sections; if this is impossible, ensure that there is always a
slope of at least 2/3 cm per linear metre as compensation.
The same flue must never be used for more than one appliance.
Do not decrease the flue section by positioning the pipe connecting the stove and the flue too deep in the
flue.
4.4 Cleaning the tubes and flue
Every time you notice the draught is becoming difficult, you should clean the stove, the tubes, and the
flue.
The removal of soot and carbon residues must be carried out to the highest standards using
appropriate means. Cleaning should be performed when the stove is cold.
The junction pipe for the connection to the chimney must be shortest possible and the junction points of the
single pipes must be hermetic. The connection to the chimney must be performed with stable and strong
pipes. The pipe for smokes exhaust must be fixed hermetically to the chimney.
ATTENTION: Possible flammable pieces in the area of 20 cm round the connection pipes must be changed
with fireproof and not sensitive to heat materials.
For a good operation of the equipment it is essential that in the installation place, there is sufficient air for
combustion. This means that through suitable openings, air must circulate for the combustion, even with
doors and windows closed.
The draught in the chimney should be 12 Pa – The measurement must be done always with the stove
being hot. When the draught exceeds 15 Pa it is necessary to reduce the same with the installation of an
additional flue adjuster (butterfly valve) on the exhaust pipe or in the chimney.

5. WOOD

Only burn dry wood! You must not only select quality wood but it must also be dry at the moment in
which you use it.
Remember that the calorific power of the wood drops considerably as the presence of humidity
means that a large part of the heat produced is used to evaporate the water and, furthermore, the risks of
obstruction increase rapidly with the condensation of the vapors in the flue.
Recommended humidity of wood is up to 20%.
5.1 DRYING
Damp wood not only burns badly but also makes the lighting of the fire difficult and damages the flue.
The water vapor transports condensible products such as acetic acid, alcohol, methyl alcohol and tars
which contribute to the formation of incrustations which are detrimental for the efficiency of your stove.
Fresh cut wood is useless as a fuel. Actually a considerable part of the energy produced is only used to
