2.2 ZONEHEATINGANDHOWTOMAKEITWORKFORYOU
YournewOsburnMatrixwoodinbuilt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.
Housesofmoderatesizeandrelativelynewconstructioncanbeheatedwithaproperlysizedand
locatedwoodinbuilt.Wholehousezoneheatingworksbestwhentheinbuilt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inbuilt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inbuilt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inbuilt,thesize,layoutandageofyourhomeandyourclimatezone.Three‐
seasonvacationhomescanusuallybeheatedwithsmallerwoodinbuilts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

OsburnMatrixInbuiltInstallationandOperationManual
10______________________________________________________________________________
youusedanolderconventionalwoodinbuilt.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inbuilt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inbuilt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INBUILTMADEOF?
Thebodyofyourwoodinbuilt,whichismostofitsweight,iscarbonsteel.Shoulditeverbecome
necessarymanyyearsinthefuture,almosttheentirewoodinbuiltcanberecycledintonew
products,thuseliminatingtheneedtominenewmaterials.
Thepaintcoatingonyourwoodinbuilt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1093°C(2,000°F.)Itisnot
consideredhazardouswaste.Disposalatalandfillisrecommended.
Firebrickismainlycomposedofsilicondioxide,alsoknownassilica,aproductprocessedfroma
minedmineral.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inbuilt,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inbuilts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.
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inbuiltverydifficult.Themostcommonstandardlengthof
firewoodis400mm(16”).

OsburnMatrixInbuiltInstallationandOperationManual
12______________________________________________________________________________
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.
3.2.5 HOWTODRYFIREWOOD
Firewoodthatisnotdryenoughtoburnisthecauseofmostcomplaintsaboutwoodinbuilts.
Continuallyburninggreenorunseasonedwoodproducesmorecreosoteandinvolveslackofheat
anddirtyglassdoor.SeeSection5:Maintainingyourwoodheatingsystemforconcernsabout
creosote.

OsburnMatrixInbuiltInstallationandOperationManual
______________________________________________________________________________13

Herearesomethingstoconsiderinestimatingdryingtime:

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inbuilt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inbuilt,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

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inbuilts.
4.3.1 CONVENTIONALFIRESTARTING
Theconventionalwaytobuildawoodinbuilt 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INBUILT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.
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.

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inbuilt.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.
Whenyouburnincycles,yourarelyneedtoopenthewoodinbuilt’sloadingdoorwhilethewood
isflaming.Thisisanadvantagebecausethereismorechancethatsmokewillleakfromthewood
inbuiltwhenthedoorisopenedasafullfireisburning.
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inbuiltisrelativelycool,but
thereisstillsomefluesystemdrafttodrawtheashdustintothewoodinbuiltandpreventitfrom
comingintotheroom.
NOTE:Thefanshouldbeturnedin“OFF”position(2)priortoashremovaltoavoidashestobe
pulledtowardstheinbuiltandthenpushedintotheroom.

Afterasheshavebeenremovedfromthewoodinbuilt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.

______________________________________________________________________________19
4.4.4 FIRINGEACHNEWLOADHOT
Placethenewloadofwoodonandbehindthecharcoalandnottooclosetotheglass.Closethe
doorandopentheaircontrolfully.Leavetheaircontrolfullyopenuntilthefireboxisfullof
flames,thewoodhascharredtoblackanditsedgesareglowingred.Firingeachloadofwoodhot
accomplishesafewthings:
•drivesthesurfacemoisturefromthewood,
•createsalayerofcharonthewood,whichslowsdownitsreleaseofsmoke,
•heatsthefireboxcomponentssotheyreflectheatbacktothefire,and
•heatsthefluesystemsoitcanproducestrong,steadydraftfortherestofthecycle.
Althoughitisimportanttofireeachnewloadhottoprepareforacleanburn,donotallowthefire
toburnatfullintensityformorethanafewminutes.
DONOTLEAVETHEWOODINBUILTUNATTENDEDWHILEANEWLOADISBEINGFIREDHOT.
DONOTOVERFIRE.
Whenyouburnanewloadofwoodhottoheatupthewood,thewoodinbuiltandtheflue
system,theresultwillbeasurgeofheatfromthewoodinbuilt.Thisheatsurgeiswelcomewhen
theroomtemperatureisalittlelowerthandesirable,butnotwelcomeifthespaceisalready
warm.Therefore,alloweachloadofwoodtoburndownsothatthespacebeginstocooloffalittle
beforeloading.Lettingthespacecoolbeforeloadingisoneofthesecretstocleanburningand
effectivezoneheating.
4.4.5 TURNINGDOWNTHEAIRSUPPLY
Oncethefirewood,fireboxandfluesystemarehot,youcanbegintoreducetheairsupplyfora
steadyburn.
Asyoureducetheairsupplytothefire,twoimportantthingshappen.First,thefiringrateslows
downtospreadtheheatenergyinthefueloveralongerperiodoftime.Second,theflowrateof
exhaustthroughthewoodinbuiltandflueslowsdown,whichgivesmoretimeforthetransferof
heatfromtheexhaust.Youwillnoticethatasyoureducetheairsetting,theflamesslowdown.
Thisisyourindicationthatthewoodinbuiltisburningatitspeakefficiency.
Iftheflamesgetsmallandalmostdisappearwhenyouturndowntheair,youhaveturneddown
theairtooearly,oryourfirewoodiswetterthanitshouldbe.Withgoodfuelandcorrectair
controluse,theflamesshouldslowdown,butshouldstaylargeandsteady,evenastheairsupply
isreduced.

4.5 FANOPERATION
Allowthewoodinbuilttoreachoperatingtemperature(approximatelyonehour),beforeturning
onthefan,sinceincreasedairflowfromthefanwillremoveheatandaffectthestart‐up

switchintheautomaticposition(3).Thefanwillstartautomaticallywhenthewoodinbuiltishot
enoughanditwillstopwhenthewoodinbuilthascooleddown.Youcanalsosettheswitchtothe

4.5.1 BUILDINGDIFFERENTFIRESFORDIFFERENTNEEDS
Usingtheaircontrolisnottheonlywaytomatchthewoodinbuilt’sheatoutputtotheheat
demand.YourhousewillneedfarlessheatinAprilthaninJulytobekeptatacomfortable
temperature.Ifyoufillthefireboxfullinfallweather,youwilleitheroverheatthespaceorturn
thewoodinbuiltdownsomuchthatthefirewillbesmokyandinefficient.Herearesome
suggestionsforbuildingfirestomatchdifferentheatdemand.
4.5.1.1 SmallFirestoTaketheChillOfftheHouse
Tobuildasmallfirethatwillproducealowheatoutput,usesmallpiecesoffirewoodandload
themcrisscrossinthefirebox.Thepiecesshouldbeonly75mmto100mmindiameter.After
rakingthecoals,youcanlaytwopiecesparalleltoeachothercornertocornerinthefireboxand
laytwomoreacrossthemintheotherdirection.Opentheaircontrolfullyandonlyreducetheair
afterthewoodisfullyflaming.Thiskindoffireisgoodformildweatherwhenyouarearoundto
tendthewoodinbuiltandshouldprovideenoughheatforfourhoursormore.Smallfireslikethis
areagoodtimetousesofterwoodspeciessotherewillbelesschanceofoverheatingthehouse.
