This image shows all possible assembly positions with
relative height indications. In this regard, please note
that installation at a 90° angle generates more heat than
discharge ow. Smoke return should be vertical or at an
angle of 45°.
SMOKE FAN ASSEMBLY
The forced draught smoke fan, complete with smoke tting, is supplied separately with the boiler.
During installation, the fan is secured to the discharge ange of the boiler together with the fastening nuts and perimeter gasket.
To facilitate installation, the smoke inlet can be installed in dierent positions, with the option to rotate it by 180°.
ATTENTION The smoke fan is supplied separately. Insert it into the smoke duct at the back, tighten the wing nuts
completely, connect it to the power supply outlet and check if it operates correctly - suction.
THE FLUE
The size, installation and connection of the ue to the boiler must be carried out by an authorised company DM 37/08 Letter
C” of re engineers and chimney sweepers according to UNI 10683.
The ue must develop a sufcient draught to convey and transport combustion smoke outdoors at all operating speeds. It is important
to have an adequately sized self-sufcient ue for the boiler to operate correctly.
Draught depends on combustion, power and duration of the boiler.
Fireplace draught is directly proportional to the diameter, height and coarseness of the internal wall. Smoke from another appliance
must not ow into the ue connected to the boiler.
ATTENTION: comply with the provisions of Standard UNI10683 with regard to ue connection and ammable materials. The ue
must be at a suitable distance from ammable or combustible materials by means of adequate insulation or an air gap.
SMOKE DUCT
The heat generator operates with negative pressure and is equipped with an output fan for smoke extraction. The generator must only have
one discharge system. It is not permitted to have a ue that is shared with other devices.
Components of the smoke extraction system must be selected based on the type of device to install and according to:
UNI/ TS 11278 in the case of metal replaces, with special reference to the designation.
UNI EN 13063-1 and UNI EN 13063-2, UNI EN 1457, .-UNI EN 1806: in the case of non-metal replaces.
The smoke duct must be as short as possible.
A T-tting must be installed with a condensation collection cap at the bottom of the vertical section.
The vertical duct can either be inside or outside the building. If the smoke duct is installed inside an existing ue, it must be certied for
solid combustion.
If the smoke duct is outside the building, it must still be insulated.
It must be possible to inspect all sections of the smoke duct.
Inspection openings must be provided for cleaning.
Connection must be carried out with stable, sturdy pipes that comply with all Standards and Regulations in force and according to the
provisions of Law, and secured well to the ue.
The internal diameter of the connection pipe must correspond to the external diameter of the smoke discharge section of the
appliance (UNI 10683).
