2. THEORETICAL NOTIONS FOR THE INSTALLATION
2.1 PELLETS
Thepelletisobtainedbyprocessingthesawdustproduced
duringworkingwoodandtimber(driedwoodandpaintfree).The
compactnessofthematerialisguaranteedbytheligninwhichis
contained in the wood itself and allows the production of pellets
withouttheuseofgluesorbinders.
The market offers different types of pellets with characteristics
thatvarybasedonmixturesofwoodused.Thediametervaries
between6and8mm,withastandardlengthbetween5and30
mm. The pellets of good quality has a density ranging from 600
to more than 750 kg/m3with a water content that is maintained
between5%and8%ofitsweight.
Inadditiontobeinganenvironmentallyfriendlyfuel,asyoupush
thelimitsofwoodresiduesresultinginacleaner-burningthan
that produced with fossil fuels, the pellets also have technical
advantages.Whileagoodwoodhasacaloricvalueof4.4kW/kg
(15%RH,after18monthsofseasoning),thepelletis4.9kW/kg.
Toensuregoodcombustion,andnopowerproblems,itisimpera-
tive that the pellets are stored in a dry place, protected from dirt,
and the thermo stove is placed in a place where the conditions

power pellets in the tank. The pellet is usually supplied in 15 kg
bags,sostorageisveryhandy.
Agoodqualitypelletensuresgoodcombustionloweringharmful
emissions into the atmosphere.
If the fuel is poor, the more often cleaning inside the grate and the combustion cham-
ber will be required.

2.2 PRECAUTIONS FOR INSTALLATION
IMPORTANT!
Installationandassemblyofthestovemustbecarriedoutbyqualiedpersonnel.
Thestovemustbeinstalledinasuitablepositiontoallowthenormaloperationsofopeningandordinary
maintenance.
Thesitemustbe:
● capableofprovidingtheenvironmentalconditionsforoperation
● equippedwithpowersupply230V50Hz
● capableoftakinganadequatesystemforsmokedischarge
●provided with external ventilation
●provided with an earth connection complying with IEC standards
Thestovemustbeconnectedtoauepipeoraninternalorexternalverticalductconformingtocurrentstan-
dardsUNI7129-71319615.Thestovemustbepositionedinsuchawaythattheelectricalplugisaccessible.
The stove must be connected to a ue pipe or a vertical duct which can discharge the fumes at the hig-
hest point of the building. The fumes are however derived from the combustion of wood products and
if they come into contact with or close to walls, they can make dirty marks. Also take care because the
fumes are very hot but almost invisible, and can cause burns on contact. The holes for the passage of
the smoke pipe and for the intake of air from outside should be made before positioning the stove unit.
2.3 OPERATING ENVIRONMENT
IMPORTANT!
Forproperoperation,andauniformdistributionoftemperature,
thestoveshouldbeplacedinalocationwithanairowthat
guaranteestheairneededforcombustionofthepellets(should
beavailableapproximately40m3/h) according to the installation
and the second regulations in the country.
Thevolumeoftheenvironmentmustnotbelessthan30m3.
The air must enter through permanent openings on the walls
(near the stove) with a minimum of 100 square centimeters.

2.4 CONNECTION TO THE EXTERNAL AIR INTAKE

combustionequipmentandventilation.Thiscanbedonebymeansof
permanentopeningsonthewallsthatgivetheroomtobeventilatedto
the outside, ventilation ducts or through individual or collective. Within
this scope, the outer wall near the stove must have an opening minimum
100 cm2,protectedbyagridinsideandoutside.
The air intake must also:

●beprotectedbyagrate,wiremeshorothersuitableprotection,provideditdoesnotreducetheminimumsection.
●positioninasuitablemannerastopreventitfrombeingobstructedinanyway
It is prohibited to connect the air directly to the stove (communicating directly from the out-
side), to avoid compromising thermodynamic performance, however it is required that the
conditions still guarantee about 50 m3/h of air replacement, as provided in the current UNI
10683.

2.5 CONNECTION OF SMOKE DISCHARGE PIPE
Whenmakingtheholefortheuepipeitmustbetaken
intoaccountthepossiblepresenceofinammable
materials. If the hole has to go through a wood wall or
otherthermolabilematerial,theinstallerMUSTusethe
Industrial insulated pipe (with min thermal conductivity
of 0.07 W/m°K). The same applies if the stove pipe
mustgoverticalorhorizontalsectionsremainnear

It should always use pipes and ttings with
appropriate seals to ensure airtightness in
order to avoid possible harmful CO fumes
into the environment.
All sections of the exhaust duct must be
inspectable and removable to allow for
periodic cleaning of the interior, which is necessary
for the proper functioning of the system (T-piece
with inspection). Position the stove strict accordan-
ce with all regulatory requirements and attention to
highlighted date
All changes direction 90 degrees of the ue gas channel must be prepared if possible, with the appro-
priate ttings to "T" with inspection. It is absolutely forbidden to use a net at the end of the hose as it
can cause serious problems for the proper and safe operation of the stove.
In connection do not use the chimney sections of pipe horizontally, but always the same place at an
angle of 5° minimum to rise, possibly avoiding the use of a 90-degree (you can use up to 3) and use
preferably 45° curves. It is recommended to not use a total length of the pipe diameter 80 mm, greater
than 6 m in total.

2.6 CONNECTION TO THE CHIMNEY
The chimney must have inside dimensions of no more
than cm. 20X20 or 20 cm diameter. In the case of
larger or poor condition of the chimney (ie: cracks, poor
insulation, etc.) it is recommended to insert stainless
steeltubeinthechimneyofaofsuitablediameterfor
its entire length, to the very top. Check with suitable
instruments that there is a minimum draft. Gua-
ranteed 15 Pa. Atthebottomofachimneyinspection

installed according to regulations for wind force.
This type of connection must guarantee of 15
