9.3.1 FLUE OUTLET / FLUE SYSTEM COMPONENTS
Every chimney must have minimum number of components as laid down by standard UNI EN 10683 which are also indicated in the
figure below.
ATTENTION:
Wall outlets or outlets installed on the outer front wall without the use of a chimney/flue outlet /flue pipe to
convey the combustion products to the roof, are strictly prohibited.
9.3.2 CONTROLS PRIOR TO INSTALLING THE APPLIANCE
The user must possess a certificate of conformance for the flue outlet
(Ministerial Decree 22 January 2008, no. 37).
The flue outlet must be built in compliance with UNI 10683.
The smoke exhaust shown in the following figures is the best solution to
facilitate the discharge of smoke even when the fan is not operational, such as
for example if there is an electrical power failure. A minimum drop of 2/3 metres
is required between the T terminal on the outside of the building and the outlet
at the back of the generator, to facilitate the discharge of residual combustion
smoke in the case described above (otherwise the residues would stagnate
inside the firebox and exhaust into the environment with added the possibility
of explosions).
If the flue outlet is too big it is necessary to insert a stainless steel or porcelain-
coated steel tube with a diameter not exceeding 150mm. Seal area where the
inlet and outlet part of the smoke exhaust meets the wall.
It is strictly forbidden to apply mesh to the end of the outlet tube , as it could
cause the appliance to malfunction. If the smoke tube is installed in a fixed
position it is advisable to provide inspection openings for clean-out purposes
especially in the horizontal sections.
These openings are essential to allow for the
removal of ash and unburned products which tend
to accumulate along the discharge path. The
appliance functions with the combustion chamber in
a vacuum, while the discharge of smoke to the flue
outlet has a slight pressure, consequently it is
imperative to ensure that the discharge system is
hermetically sealed.
The smoke discharge tube must be made from
suitable materials such as for example: porcelain-coated steel tubes, with the various fittings sealed with red silicone (resistant to
350°C). The outer casing of the tube must be made with insulating material (mineral wool, ceramic fiber) or use pre-insulated tubing.
THE FLUE OUTLET MUST BE USED ONLY FOR THE APPLIANCE.
