YouareremindedthattheESC(EuropeanStandardisationCommittee)isintheprocessof

definingfutureEuropeantechnicalstandardsthatwillgovernboththetechnicalfeaturesofthis

fuelandtheeconomicandenvironmentalaspectsassociatedwiththeproductionline.



1.3Fuelfeatures

Themainfeatureofthisheateristhatitburnsanaturalfuel(thepellet)obtainedinan

environmentally‐friendlywayfromscrapsofthetimberindustry(woodchippings,sawdust,

etc.).



Woodchippingsandsawdustfromwoodproducts,afterhavingbeendulyre‐cleanedanddried,

arecompactedinstate‐of‐the‐artveryhigh‐pressureplants,intopureroundedwoodpieces:the

pellet.Eachroundedpiececanhavevariablelengthsandthicknesses,respectivelybetween1÷3

cminlengthand6÷8mmindiameter.Thepellet’smainfeaturesarelowmoisturecontent

(below12%),itshighdensity(=600kg/m30aswellasitsregularityandcompactnessthatgive

thistypeoffuelcharacteristicsofhighcalorificpower(I.C.P.4000÷5000kcal/kg).



2TheDINprohibitstheuseofanyaddedsubstance.However,thisprohibitionisnotvalidforsmallheatingsystems.



DINplusproposesthecombinationofthequalitativeparametersproposedbystandardDIN

51731andbyAustrianstandardÖnormM7135.



Thepellet,asalsostipulatedbycurrentItalianlegislationgoverningthecommercial

technologycharacteristicsoffuels(DPCM2.10.1995)mustbeproducedexclusivelywith

untreatedwoodchippings,withnootheraddedmaterials.



Itisstrictlyprohibitedtouseanysolidorliquidfuelotherthanthepelletto

feedthestove.



Inordertooptimisetheuseoftheproductwerecommendusingpelletswhich

havebeengivenaqualitycertificatebyanauthorisedbody.Theuseofpelletsother

thanthosedirectedbytheinstallermayleadtoheatermalfunctionandtothe

guaranteebecominginvalid.



Storingandevenmovingthepelletsareimportantoperationstobecarriedoutwithcare:



•Thefuelmustbestoredinadryplaceawayfromcold;

•Thepelletsmustbemovedsoastoavoidexcessive   

crumblingintofinedust.



Observanceofthesetwosimplerulesmakesitpossiblebothtoobtainbetterfuel

efficiencyandtopreservethemechanicalmovingpartsoftheapparatus.



Iftheproductiskeptoutofserviceforlongperiodsoftime(overfifteendays),the

tankmustbeemptiedofanyresidualfuel,inordertopreventanyexcessive

dampnessofthefuelcausingtheproducttomalfunction.



Ahighmoisturecontentinthepelletmaycauseittocrumbleintodust,thatcreates

agreateraccumulationofresidueinthebrazierareaandblockageofthefuelfeed

system(auger).



2INSTALLATIONINS.

Foracorrectinstallationoftheheaterandtopreventtheuprisingofpossibleproblemsduring

runningtheheater,wearesupplyingsomesimplerecommendationsfortheinstallation–

accordingtoregulationsUNI10683,UNI9615,UNI9731,UNI‐CIG7129andfollowingupdating

referredtodomesticgasuseunits.



2.1Indoorpositioning



Ourproductisaheaterthatdrawsairthatisnecessaryforitscombustionprocessdirectlyfrom

theenvironmenttobeheated.

Forthisreasonandfortheevenmoreimportantreasonofsafetyforthepeopleusingit,the

heatermustbeinstalledinasufficientlyventilatedplaceinordertoguaranteeacontinuous

flowofairatalltimes.



Itisthereforeessentialtomakeairventsconnectedtotheoutside.Seeexampleinfigure2.1



DetailA



Figure2.1:Exampleofmakinganairvent.



IncompliancewiththeindicationsreportedunderregulationUNI10683,the

airinletsmusthavethefollowingfeatures:

1.Theymusthaveaclearspaceofnotlessthan80cm2;

2.Theymustbemadeataheightclosetothefloor;

3.Theymustbesuitablyprotectedbyawiremeshorgrilleinsuchaway

thattheminimumpassagespaceisnotandmaynotbereduced;

4.Theymustbeplacedinsuchawaythattheyarenotobstructedin

anyway.



Thecorrectinflowoffreshairmaybeguaranteedbyusingapertures

towardsanadjacentroom,providedthatithasdirectventilation,and

itisnotanenvironmentwithafirehazard,suchas store‐rooms,garages

or warehouses,asregulatedbyregulationUNI10683



Ourheatershouldbeinstalledinroomswherethereisnoequipmentoperatinginairtight

conditionsinrelationtotheroom,orapparatusthatmayplacetheroomitselfinavacuumin

relationtotheoutsideenvironmentandthuscauseproblemsofpoordraughtforourproduct(

regulationUNI10683).



Combustionproductsfromourheatermustnotbeextractedintosharedflues.



Whencheckingequipmentcompatibility,itisgoodpracticetocheckwhetherthesupportplane

(floor)hasabearingcapacity(kg)thatissuitedtotheweightoftheproductitmustsustain.If

not,correctsafetymeasuresmustbetaken(eg.Load‐distributionplate).



Wheninstallingtheheater,itisadvisabletoplanasuitabledistancefromthewallsoftheroom

inordertoprovideanyaccessnecessarybothintherear(atleast20cmisrecommended)and

tothesideoftheproduct(80cmisrecommended)(forexampletocarryoutappropriate

cleaningworkcorrectly).
