EN - Rev. 1.0
Pellet properties
The appliance has been tested with all types of pellets available on the market. The pellets must have the following
properties:
-Diameter 6 mm.
-Maximum length 35 mm.
-Maximum humidity content 8 –9 %.
-100% wood. Totally additive-free.
-Maximum ash residue 1.1 %.
To obtain good performance from the appliance, we recommend using good quality pellets. Pellets should be poured
into the tank using a shovel, and not directly from the bag.
Good quality pellets should have the following properties:
-Constant diameter cylinders with a smooth, shiny surface;
-There should not be a lot of sawdust inside the packaging;
-After grabbing a bunch of pellets and placing them into a container filled with water, good-quality pellets will sink and
poor-quality ones will tend to float;
-The quality certification data, in particular conformity to international standards such as EN14961-2, DIN 51731 and
O-NORM M7135, should be indicated on the packaging;
-The packages should be intact since pellets tend to absorb humidity. Humidity not only reduces the calorific value
and increases the amount of flue gases expelled, but also causes swelling of the product which may create problems
with the appliance.
The production of pellets must be compliant with some international standards (such as EN14961-2, DIN 51731 and O-
NORM M7135) which establish minimum values for quality checks on pellets. To facilitate the right choice of the
combustible material you can find below one of the most common certification marks identifying the quality of the pellets:
The use of poor quality pellets or any other material can damage the appliance operation, voiding the warranty
and exempting the manufacturer from all liability.
In order to guarantee trouble-free combustion, the pellets must be stored in a dry place.
REQUIREMENTS OF THE PLACE OF INSTALLATION
Positioning
The initial phase for best installation of the appliance is to determine its optimum location; the following elements need to
be considered:

The unit must be installed on a floor with a suitable load capacity. If the existing building does not fulfil this requirement
appropriate measures (e.g. load distribution plate) must be taken.
The minimum safety distance from flammable materials must be at least 200 mm from the sides and back of the
appliance, 800 mm from the front and 750 mm from the upper part.
The installation must guarantee easy access for cleaning the appliance, the flue gas exhaust pipes and the flue, and any
subsequent maintenance operation by the Authorised technical assistance centre.
Once you have found the best location for the appliance, position it following the instructions given below.
The appliance must not be installed in small rooms, bedrooms, bathrooms or in areas with an explosive atmosphere
(e.g. garages).
Spaces around and above the appliance
The figure below shows the minimum distances from walls or other not-easily-removable furniture, that need to be taken
into consideration when positioning the appliance.
Any shelves or false ceilings mounted above the appliance must be at least 75 cm away from the top part of it.
Furniture and movable objects made from flammable materials must be positioned at least 20 cm from the side surfaces
of the appliance; these objects must be moved when performing maintenance on the appliance.
Protect all structures that can catch fire against the radiated heat of the fire.
Any extra intervention by the Authorised technical assistance centre, which requires the appliance to be
disconnected from the system, will not be covered under warranty as described in the chapter “Standard
Warranty Conditions”.
External air intake
During operation, the appliance takes in air from the environment in which it is installed; It is therefore essential that this
air is replaced through an external air vent. The absence of the air vent may affect the flue draught and therefore the
combustion and the safety of the appliance.
Therefore it is mandatory to install an external air vent with a minimum completely free passage of at least 80 cm2
(round hole with minimum diameter of 15 cm protected with a special fixed large mesh grille).
If it not possible to put the external air vent in the same room as where the appliance is installed, this hole can be made
in an adjoining room as long as this room communicates permanently, by means of a transit hole (15 cm minimum
diameter).
The hole must be protected externally with a fixed grille. The protective grille must be checked periodically to ensure that
it is not obstructed, thereby impeding the passage of air. Therefore keep the air vents clear of obstructions.
The UNI 10683 Standard FORBIDS the drawing of combustion air from garages, warehouses storing combustible
materials, or from business premises with a fire hazard.

If there are other heating or extraction devices inside the room, the air vents must guarantee a sufficient amount of air for
properly operating all the devices.
Only sealed appliances (e.g. C type gas appliances, according to the UNI 7129 Standard) or appliances that do not
cause a lower pressure compared with the external environment can pre-exist or be installed in the place where the
appliance is installed.
Extractor fans can cause malfunctions to the appliance if used in the same room.
The flue and connection to the same
The flue is an essential element for the efficient operation of the appliance. The flue must have the minimum cross-
sectional dimensions stated in the appliance’s technical specifications (80 mm). Each product must be equipped with its
own flue, without other adjoining elements (boilers, chimneys, stoves, etc.). The flue dimensions are closely related to its
height, which must be measured from the appliance flue gas outlet to the base of the stack. In order to guarantee
adequate draught, the surface of the chimney flue outlet must be double the flue cross-section. The discharge pipe for
combustion products generated by the forced draught device, must comply with the following requirements:
-It must seal off the combustion gases, as well as being waterproof and suitably isolated and insulated in relation to
the conditions of use (refer to UNI 9615);
-It must be made of suitable materials capable of withstanding normal mechanical stress, heat, and the effects of
combustion gases and condensate, if any;
-It must go upwards after the vertical section, for the entire remaining part, with a minimum gradient of 5%. The sub-
horizontal section must not have a length greater than ¼ of the effective height H of the flue or chimney, and must
not be longer than 2,000 mm;
-It must preferably have a round internal cross-section: square or rectangular cross-sections must have rounded
corners with radius not inferior to 20 mm;
-It must have a constant, free and independent internal cross section;
-Rectangular cross-sections must have a maximum ratio of 1.5 between the sides;
- It must be insulated to prevent the fumes from cooling and forming condensation;
-Parts made from non-combustible materials (it is absolutely prohibited the use of aluminium flue) - capable of
withstanding combustion gases and potential condensation - must be used for mounting the flue gas pipes (for the
section from the appliance to the flue inlet);
-It is forbidden to use fibre cement pipes to connect the appliance to the flue;
-Flue gas conduits must not pass through rooms in which the installation of combustion devices is prohibited;
-The flue gas conduits must be assembled in such a way as to guarantee adequate sealing of flue gases during low
pressure operation of the appliance;
- The installation of horizontal sections is prohibited;
- It is prohibited to use counter sloping elements;
-The flue gas pipe must allow for the recovery of soot or be cleanable, and must have a constant cross-section;
