2.2 ZONEHEATINGANDHOWTOMAKEITWORKFORYOU

YournewOsburnMatrixwoodfireisaspaceheater,whichmeansitisintendedtoheattheareait

isinstalledin,aswellasspacesthatconnecttothatarea,althoughtoalowertemperature.Thisis

calledzoneheatinganditisanincreasinglypopularwaytoheathomesorspaceswithinhomes.

Zoneheatingcanbeusedtosupplementanotherheatingsystembyheatingaparticularspace

withinahome,suchasabasementfamilyroomoranadditionthatlacksanotherheatsource.

OsburnMatrixInstallationandOperationManual

10______________________________________________________________________________

Housesofmoderatesizeandrelativelynewconstructioncanbeheatedwithaproperlysizedand

locatedwoodfire.Wholehousezoneheatingworksbestwhenthewoodfireislocatedinthepart

ofthehousewherethefamilyspendsmostofitstime.Thisisnormallythemainlivingareawhere

thekitchen,diningandlivingroomsarelocated.Bylocatingthewoodfireinthisarea,youwillget

themaximumbenefitoftheheatitproducesandwillachievethehighestpossibleheating

efficiencyandcomfort.Thespacewhereyouspendmostofyourtimewillbewarmest,while

bedroomsandbasement(ifthereisone)willstaycooler.Inthisway,youwillburnlesswoodthan

withotherformsofheating.

Althoughthewoodfiremaybeabletoheatthemainlivingareasofyourhousetoanadequate

temperature,westronglyrecommendthatyoualsohaveaconventionaloil,gasorelectricheating

systemtoprovidebackupheating.

Yoursuccesswithzoneheatingwilldependonseveralfactors,includingthecorrectsizingand

locationofthewoodfire,thesize,layoutandageofyourhomeandyourclimatezone.Three‐

seasonvacationhomescanusuallybeheatedwithsmallerwoodfiresthanhousesthatareheated

allwinter.

2.3 THEBENEFITSOFLOWEMISSIONSANDHIGHEFFICIENCY

ThelowsmokeemissionsproducedbythespecialfeaturesinsidetheOsburnMatrixfireboxmean

thatyourhouseholdwillreleaseupto90percentlesssmokeintotheoutsideenvironmentthanif

youusedanolderconventionalwoodfire.Butthereismoretotheemissioncontroltechnologies

thanprotectingtheenvironment.

Thesmokereleasedfromwoodwhenitisheatedcontainsabouthalfoftheenergycontentofthe

fuel.Byburningthewoodcompletely,yourwoodfirereleasesalltheheatenergyfromthewood

insteadofwastingitassmokeupthefluesystem.Also,thefeaturesinsidethefireboxallowyouto

reducetheairsupplytocontrolheatoutput,whilemaintainingcleanandefficientflaming

combustion,whichbooststheefficientdeliveryofheattoyourhome.

Theemissioncontrolandadvancedcombustionfeaturesofyourwoodfirecanonlyworkproperly

ifyourfuelisinthecorrectmoisturecontentrangeof15to20percent.SeeSection3ofthis

manualforsuggestionsonpreparingfuelwoodandjudgingitsmoisture.

2.4 OSBURN’SCOMMITMENTTOYOUANDTHEENVIRONMENT

TheOsburnteamiscommittedtoprotectingtheenvironment,sowedoeverythingwecantouse

onlymaterialsinourproductsthatwillhavenolastingnegativeimpactontheenvironment.

2.4.1 WHATISYOURNEWWOODFIREMADEOF?

Thebodyofyourwoodfire,whichismostofitsweight,iscarbonsteel.Shoulditeverbecome

necessarymanyyearsinthefuture,almosttheentirewoodfirecanberecycledintonew

products,thuseliminatingtheneedtominenewmaterials.

OsburnMatrixInstallationandOperationManual

______________________________________________________________________________11

Thepaintcoatingonyourwoodfireisverythin.ItsVOCcontent(VolatileOrganicComponents)is

verylow.VOCscanberesponsibleforsmog,soallthepaintusedduringthemanufacturing

processmeetsthelatestairqualityrequirementswithregardstoVOCreductionorelimination.

Theairtubesarestainlesssteel,whichcanalsoberecycled.

TheC‐Castbaffleismadeofanaluminosilicatefibrematerialthatiscompressedwithabinderto

formarigidboard.C‐Castcanwithstandtemperaturesabove1093°c.Itisnotconsidered

hazardouswaste.Disposalatalandfillisrecommended.

Firebrickismainlycomposedofsilicondioxide,alsoknownassilica,anearthderivedproduct.Itismost

commonlyfoundinnatureintheformofsandandclay.Disposalatalandfillisrecommended.

Thedoorandglassgasketsarefibreglasswhichisspunfrommeltedsand.Blackgasketshavebeen

dippedintoasolvent‐freesolution.Disposalatalandfillisrecommended.

Thedoorglassisa5mmthickceramicmaterialthatcontainsnotoxicchemicals.Itisbasicallymadeof

rawearthmaterialssuchassandandquartzthatarecombinedinsuchawaytoformaglassathigh

temperatures.Ceramicglasswillnotre‐meltinthesamewayasnormalglass,soitshouldnotbe

recycledwithyourregularhouseholdproducts.Disposalatalandfillisrecommended.

3.2 HOWTOPREPAREORBUYGOODFIREWOOD

3.2.1 WHATISGOODFIREWOOD?

Goodfirewoodhasbeencuttothecorrectlengthforthewoodfire,splittoarangeofsizesand

stackedintheopenuntilitsmoisturecontentisreducedto15to20percent.

3.2.2 TREESPECIES

Thetreespeciesthefirewoodisproducedfromislessimportantthanitsmoisturecontent.The

maindifferenceinfirewoodfromvarioustreespeciesisthedensityofthewood.Hardwoodssuch

asgums,Manukaorironbarkaredenserthansoftwoods.Hardwoodwillproducelong‐lastingcoal

bedscombinedtomoreheatandlongerburncycles.

Old,leakycastironwoodfireswouldn’tholdafireovernightunlesstheywerefedlargepiecesof

hardwood.Thatisnolongertrue.Youcansuccessfullyheatyourhomebyusinglesswoodand

givetheforestabreakatthesametime.

OsburnMatrixInstallationandOperationManual

______________________________________________________________________________13

3.2.3 LOGLENGTH

Logsshouldbecutabout25mm(1”)shorterthanthefireboxsotheyfitineasily.Piecesthatare

slightlytoolongmakeloadingthewoodfireverydifficult.Themostcommonstandardlengthof

firewoodis400mm(16”).

Thepiecesshouldbeaconsistentlength,withamaximumof25mm(1”)variationfrompieceto

piece.



3.2.4 PIECESIZE

Firewooddriesmorequicklywhenitissplit.Largeunsplitroundscantakeyearstodryenoughto

burn.Evenwhendried,unsplitlogsaredifficulttoignitebecausetheydon’thavethesharpedges

wheretheflamesfirstcatch.Logsassmallas75mm(3”)shouldbesplittoencouragedrying.

 

Woodshouldbesplittoarangeofsizes,fromabout75mmto150mm(3”to6”)incrosssection.

Havingarangeofsizesmakesstartingandrekindlingfiresmucheasier.Often,thefirewood

purchasedfromcommercialsuppliersisnotsplitfinelyenoughforconvenientstoking.Itis

sometimesadvisabletoresplitthewoodbeforestackingtodry.

OsburnMatrixInstallationandOperationManual

3.2.5 HOWTODRYFIREWOOD

Firewoodthatisnotdryenoughtoburnisthecauseofmostcomplaintsaboutwoodfires.The

complaintsusuallyinvolvealackofheatanddirtydoorglass.



Herearesomethingstoconsiderinestimatingdryingtime:

•firewoodtakesalongtimetodry

•firewoodboughtfromadealerisrarelydryenoughtoburn,soitisadvisabletobuythewood

inspringanddryityourself

•dryinghappensfasterindryweatherthanindamp,maritimeclimates

•dryinghappensfasterinwarmsummerweatherthaninwinterweather

•smallpiecesdrymorequicklythanlargepieces

•splitpiecesdrymorequicklythanunsplitrounds

•softwoodstakelesstimetodrythanhardwoods

•hardwoodslikegums,Manukaandironbarkcantakeone,oreventwoyearstodryfully,

especiallyifthepiecesarebig

•firewooddriesmorequicklywhenstackedintheopenwhereitisexposedtosunandwind;it

takesmuchlongertodrywhenstackedinawoodshed

•firewoodthatisreadytoburnhasamoisturecontentbetween15and20%byweightandwill

allowyourwoodfiretoproduceitshighestpossibleefficiency

additives.Manufacturedlogsmadeof100%compressedsawdustcanbeburned,butusecaution

inthenumberoftheselogsburnedatonetime.Startwithonemanufacturedlogandseehowthe

woodfirereacts.Youcanincreasethenumberoflogsburnedatatimetomakingsurethe

temperatureneverriseshigherthan246°C(475°F)onamagneticthermometerforinstallationon

Thisstovehasbeentestedforusewithanopendoorinconjunctionwithafirescreen(AC01315,

soldseparately).Makesurethefirescreenisproperlysecuredonthestovetoavoidanyriskof

fire.Whenthefirescreenisused,itisimportantnottoleavethestoveunattendedtorespond

promptlyintheeventofsmokespillageintotheroom.Potentialcausesofsmokespillageare

forinstallationinstructions.



4.2 YOURFIRSTFIRES

Twothingswillhappenasyouburnyourfirstfewfires;thepaintcuresandtheinternal

componentsofthewoodfireareconditioned.

Asthepaintcures,someofthechemicalsvaporize.Thevaporsarenotpoisonous,buttheydo

smellbad.Freshpaintfumescanalsocausefalsealarmsinsmokedetectors.So,whenyoufirst

lightyourwoodfire,bepreparedbyopeningdoorsand/orwindowstoventilatethehouse.Asyou

burnhotterandhotterfires,moreofthepaintedsurfacesreachthecuringtemperatureofthe

paint.Thesmellofcuringpaintdoesnotdisappearuntilyouhaveburnedoneortwoveryhot

fires.

Burnoneortwosmallfirestobeginthecuringandconditioningprocess.Thenbuildbiggerand

hotterfiresuntilthereisnolongeranypaintsmellfromthewoodfire.Oncethepaintsmell

disappears,yourwoodfireisreadyforseriousheating.

4.3 LIGHTINGFIRES

Eachpersonwhoheatswithwooddevelopstheirownfavoritewaytolightfires.Whatever

methodyouchoose,yourgoalshouldbetogetahotfireburningquickly.Afirethatstartsfast

produceslesssmokeanddepositslesscreosoteinthefluesystem.Herearethreepopularand

effectivewaystostartwoodfires.

4.3.1 CONVENTIONALFIRESTARTING

Theconventionalwaytobuildawoodfireistobunch

up5to10sheetsofplainnewspaperandplacethem

inthefirebox.Next,place10orsopiecesoffine

kindlingonthenewspaper.Thiskindlingshouldbe

verythin;lessthan25mm(1”).Next,placesome

largerkindlingpiecesonthefinekindling.Openthe

aircontrolfullyandlightthenewspaper.Ifyouhave

atall,straightfluesystemyoushouldbeabletoclose

thedoorimmediatelyandthefirewillignite.Ifyour

fluehaselbowsoranoutsidefluesystem,youmay

needtoleavethedoorclosedbutunlatchedforafew

minutesasthenewspaperignitesandheatintheflue

systemproducessomedraft.Oncethefirehas

ignited,closethedoorandleavetheaircontrolfully

open.

Aconventionalkindlingfirewithpaper

underfinelysplitwood.

DONOTLEAVETHEWOODFIREUNATTENDEDWHENTHEDOORISSLIGHTLYOPENEDDURING

IGNITION.ALWAYSCLOSETHEDOORAFTERIGNITION.

Afterthekindlingfirehasmostlyburned,youcanaddstandardfirewoodpiecesuntilyouhavea

fireoftherightsizefortheconditions.

4.3.2 THETOPDOWNFIRE

Thetopdownfirestartingmethodsolvestwoproblemswiththeconventionalmethod:first,it

doesnotcollapseandsmotheritselfasitburns;andsecond,itisnotnecessarytobuildupthefire

graduallybecausethefireboxisloadedbeforethefireislit.Atopdownfirecanprovideuptotwo

hoursofheatingormore.Thetopdownmethodonlyworksproperlyifthewoodiswell‐seasoned.

Startbyplacingthreeorfourfull‐sizedsplitpiecesofdryfirewoodinthefirebox.Next,place4or5

morefinelysplitpiecesoffirewood(50mmto75mm[2”to3”]india.)onthebaselogsatright

angles(logcabinstyle).Nowplaceabout10piecesoffinelysplitkindlingonthesecondlayerat

rightangles.

OsburnMatrixInstallationandOperationManual

______________________________________________________________________________19

Thefireistoppedwithabout5sheetsofnewspaper.Youcanjustbunchthemupandstuffthemin

betweenthekindlingandtheundersideofthebaffle.Oryoucanmakenewspaperknotsbyrolling

upsinglesheetscornertocornerandtyingaknotinthem.Theadvantageofknotsisthatthey

don’trolloffthefireastheyburn.Lightthenewspaperandwatchasthefireburnsfromtopto

bottom.

4.3.3 TWOPARALLELLOGS

Placetwospitlogsinthefirebox.Placeafewsheetsoftwistednewspaperbetweenthelogs.Now

placesomefinekindlingacrossthetwologsandsomelargerkindlingacrossthose,logcabinstyle.

Lightthenewspaper.

4.3.4 USINGFIRESTARTERS

Manypeopleliketousecommercialfirestartersinsteadofnewspaper.Someofthesestartersare

madeofsawdustandwaxandothersarespecializedflammablesolidchemicals.Followthe

packagedirectionsforuse.

Gelstartermaybeusedbutonlyiftherearenohotemberspresent.Useonlyinacoldfireboxto

startafire.

DONOTUSEFLAMMABLELIQUIDSSUCHASGASOLINE,NAPHTHA,FUELOIL,MOTOROIL,OR

AEROSOLSTOSTARTORREKINDLETHEFIRE.



4.4 MAINTAININGWOODFIRES

4.4.1 GENERALADVICE

Woodheatingwithaspaceheaterisverydifferentthanotherformsofheating.Therewillbe

variationsinthetemperatureindifferentpartsofthehouseandtherewillbevariationsin

temperaturethroughoutthedayandnight.Thisisnormal,andforexperiencedwoodburners

theseareadvantagesofzoneheatingwithwood.

Donotexpectsteadyheatoutputfromyourwoodfire.Itisnormalforitssurfacetemperatureto

riseafteranewloadofwoodisignitedandforitstemperaturetograduallydeclineasthefire

progresses.Thisrisingandfallingoftemperaturecanbematchedtoyourhouseholdroutines.For

example,theareatemperaturecanbecoolerwhenyouareactive,suchaswhendoinghousework

orcooking,anditcanbewarmerwhenyouareinactive,suchaswhenreadingorwatching

television.

Woodburnsbestincycles.Acyclestartswhenanewloadofwoodisignitedbyhotcoalsandends

whenthatloadhasbeenconsumeddowntoabedofcharcoalaboutthesamesizeasitwaswhen

thewoodwasloaded.Donotattempttoproduceasteadyheatoutputbyplacingasinglelogon

thefireatregularintervals.Alwaysplaceatleastthree,andpreferablymore,piecesonthefireat

atimesothattheheatradiatedfromonepiecehelpstoignitethepiecesnexttoit.Eachloadof

woodshouldprovideseveralhoursofheating.Thesizeofeachloadcanbematchedtothe

amountofheatneeded.

OsburnMatrixInstallationandOperationManual

20______________________________________________________________________________

Whenyouburnincycles,yourarelyneedtoopenthewoodfire’sloadingdoorwhilethewoodis

flaming.Thisisanadvantagebecausethereismorechancethatsmokewillleakfromthewood

firewhenthedoorisopenedasafullfireisburning.Thisisespeciallytrueiftheflueconnectorhas

90degreeelbowsandifthefluesystemrunsuptheoutsidewallofthehouse.

IFYOUMUSTOPENTHEDOORWHILETHEFUELISFLAMING,OPENTHEAIRCONTROLFULLYFOR

AFEWMINUTES,THENUNLATCHANDOPENTHEDOORSLOWLY.

4.4.2 ASHREMOVAL

Ashshouldberemovedfromthefireboxeverytwoorthreedaysoffulltimeheating.Donotlet

theashbuildupinthefireboxbecauseitwillinterferewithproperfiremanagement.

Thebesttimetoremoveashisafteranovernightfirewhenthewoodfireisrelativelycool,but

thereisstillsomefluesystemdrafttodrawtheashdustintothewoodfireandpreventitfrom

comingintotheroom.

Afterasheshavebeenremovedfromthewoodfireandplacedinatightlycoveredmetal

container,theyshouldbetakenoutsideimmediately.Theclosedcontainerofashesshouldbe

placedonanon‐combustiblefloororonthegroundwellawayfromallcombustiblematerials

pendingfinaldisposal.Ashesnormallycontainsomelivecharcoalthatcanstayhotforseveral

days.Iftheashesaredisposedofbyburialinsoilorotherwiselocallydispersed,theyshouldbe

retainedintheclosedcontaineruntilallcindershavethoroughlycooled.Otherwasteshallnotbe

placedinthiscontainer.

NEVERSTOREASHESINDOORSORINANON‐METALICCONTAINERORONAWOODENDECK.

4.4.3 RAKINGCHARCOAL

Rekindlethefirewhenyounoticethattheroomtemperaturehasfallen.Youwillfindmostofthe

remainingcharcoalatthebackofthefirebox,furthestfromthedoor.Rakethesecoalstowards

thedoorbeforeloading.Therearetworeasonsforthisrakingofthecoals.First,itconcentrates

themnearwheremostofthecombustionairentersthefireboxandwheretheycanignitethenew

loadquickly,andsecond,thecharcoalwillnotbesmotheredbythenewloadofwood.Ifyouwere

tosimplyspreadthecharcoalout,thenewloadwillsmoulderforalongtimebeforeigniting.



Removeashfirst,andthenrakecharcoaltowardsthefrontofthefireboxbeforeloadingsothatit

willignitethenewload.
