INTRODUCTION

Thekeystosafe,successfulandefficientwoodburningaregoodplanning,correctinstallation
andproperoperation.Pleasereadthefollowinginstructionscarefullytogetthebestfromyournewpurchase.

Modernhomeshavebetterlevelsofinsulationandaremoreenergyefficient,withmoreeffectiveandbetter
sealsondoorsandwindows.Thismakesourhomeseasiertoheat,butalsomeansthatsolidfuelappliances
mustbemorecarefullydesignedsothattheywillfunctioncorrectlyintheenergyefficient,modernhomesof
today.Themoreenergyefficientahouseis,thelessfuelisrequiredtoheatit.Lessfuelusemeanslessimpact
ontheenvironment.

Theoperationofourappliances,sothattheydonotproduceexcessivesmoke(beyondtheinitiallightupand
reloadingperiods)ismostimportant.Whenourappliancesarenotsmoking,itisanindicationthatitisbeing
operatedcorrectlyandefficiently.

Theflamesthatareseeninsidetheappliancearenotthefuelburning,butthecarbonparticlesandgasesthat
arereleasedfromthefuelonceithasbeenheatedtoasufficientlyhightemperature.Theescapeofany
unburntparticlesandsomegasesintotheatmospherearethecauseofairpollution.
Ourappliancesaredesignedtoensurethatthecombustionofallgasesandparticlestakesplacewithinthe
firebox,tomaximizetheheatoutputoftheapplianceandtominimizethedischargeofparticulateemissionsto
theatmosphere.

Itisimportanttherefore,forappliancestobeoperatedinaccordancewithourinstructionsinamannerthat
maintainsahightemperatureinthefireboxwithanadequatesupplyofairtoensureefficientcombustion.A
goodindicationofefficientcombustionisabrightlivelyflameinthefirebox.Adullflameorsmolderingfire
indicatespoororincompletecombustion.
Tomaintainadequateheatinthefirebox,itisveryimportanttousedry,wellseasonedwoodwithlessthan
20%moisturecontent.Thewoodmustbecorrectlysizedfortheparticularapplianceanditalsohelpstohave
atleastthreeorfourpiecesburningattheonetimetoassistthecombustionprocess.

Addingsinglepiecesofunseasonedorwetwoodtoafirewillreducethefireboxtemperatureandprevent
adequatecombustion.Thiswillresultinincreasedsmokeemissionscausingtheflueandinternalcomponents
oftheappliancetobecomeblockedwithtarandcreosotemorequickly.Thetarandcreosotedepositsinthe
chimneywillfuelachimneyfire.

PleasenotethatitisarequirementundertheBroseleyFiresLtd’swarrantysystemthattheinstallationof
thestoveiscarriedoutbyaCompetentPersonregisteredwithaGovernmentapprovedCompetentPersons

2. TECHNICALDESCRIPTION

TheTHERMOVERONADSAwoodburningboilerstoveissuitableforheatinglivingspaceswithinahomeor
supportingacentralheatingsystem.Thestovewillalsobesuitableforcookingawidevarietyoffoodstuffs.
Theyareidealforholidayapartmentsandweekendhousesorasaheatingsystemduringthewholeyear.

TheTHERMOVERONADSAstoveismadeofcastironandplatesofsteelmetalsheet.Thefirechamberis
internallylinedwithcastironfirebricks.Thereisaturningandextractablegrate.Thestoveisequippedwitha
panoramicdoorwithceramicglass(resistantupto700ºC)thisallowsawonderfulviewoftheflamepicture,
whilstalsopreventingoutputsofsparksandsmoke.Theintegralhotplate,allowsyoutocookonthestove.

Theapplianceisequippedwithprimaryandsecondaryaircontrols,bywhichitispossibletocontroltheburn
rateandhencetheoutputoftheappliance.

3.HEATABLEAREA(VOLUME)

Theheatingvolumeoftheappliance;accordingtoDIN18893;willvarydependingontheamountofthermal
insulationthatthepropertyhas.Propertieswithhighceilings,draughtywindowsanddoors,solidbrickwalls
andpoorinsulation,theseareallgoingtoaffectthepotentialmaximumheatingvolumeoftheappliance.

3A.KEYENVIRONMENTALCONSIDERATIONS

Tominimizetheimpactontheenvironmentthefollowingissuesneedtobeconsideredwhenproposingto
installasolidfuelappliance:

•Localauthorities(Councils)mustbeconsultedforanyrestrictionsthatmayapplytotheuseofsolid
fuelappliancesincertainareassuchassmokefreezones.
•Theappliancemustbecorrectlysizedtosuitthespaceandnecessaryclearancesmustbestrictly
adheredto.
•Theapplianceandfluesystemmustbecorrectlyinstalledtothecurrentregulationsinforceatthe
time.
•Theappliancemustbecorrectlyoperated.
•Theapplianceandfluesystemmustbeproperlymaintained.
•Itisalsoimportanttoensurethatthedwellingtobeheatedisinsulatedandisasenergyefficientasis
practical.
•Thecorrectfuelmustbeused.

Theselection,installation,correctuseandmaintenanceofwoodburningappliancesandfluesystemsare
discussedinmoredetailinthefollowingsectionsoftheseinstructions.


4.0 THE‘AIR’CONTROLS

Thestoveisfittedwithcontrolsthatadjusttheflowofairintotheunit.Itisveryimportantthatthesecontrols
arefullyunderstoodinordertoachievethebestresultsfromyourstove.
Whenoperatingthecontrols,ensurethattheyareusedinsmallincrementsandnotchangedbylargeamounts
suddenly.Donotusethemlikeanon–offswitch.
Itisimportantthatthefollowingcontrolsareusedcorrectly.

Theaircontrolsareasfollows:
•PRIMARYAIRCONTROL
•SECONDARYAIRCONTROL(AIRWASH)
•THERMOSTATCONTROL
•FLUEPATHSHUTTERCONTROL

4ATHEPRIMARYAIRCONTROL(leverB)

Theprimaryaircontrolisfoundtotherightofthemaindoor(‘B’inthe
attacheddiagram),itisinthestyleofapush/pulllever.Thiscontrolwill
beusedduringtheinitiallightingphase.

Theashdrawermustberegularlyemptied,sothattheashdoesnot
obstructtheentryofprimaryair.Thechamberinwhichthedraweris
housedwillalsoneedtobecleanedonaregularbasis,asanyashthat
spillsoverthesidesofthepanwillgetpushedtotherearofthe
chamberandinterferewiththethermostatcontroldamper.Failureto
keepthisareaclearwillresultinthedamperbeingstuckintheopen
position.

4B SECONDARYAIRCONTROL(slider)

Overthehearthdooryouwillfindthe‘secondaryair
control’inthestyleofaslider.(‘A’intheattached
diagram)
Combustionairenteringthestovethroughthisventwill
bedirecteddowntheinsideoftheglasspanel,thisis
knownasthe‘airwashsystem’.Ithelpstokeepsooty
depositsfromstickingtotheglassandobscuringtheview
oftheflames.Havingcleanglassalsoimprovestheheat
radiationtobeuninterrupted.Thiscontrolwillbeusedto
adjustthecombustionrateinsidethefirechamber.


4CTHETHERMOSTATCONTROL(lever)

Thethermostatcontrolcanbefoundattherearofthestoveontherighthandside,itissituated
abovethedirectfluepathshuttercontrol(seebelowforpositionoffluepathshutter)

Thethermostatcontroloperatesadamperthatallowsairtoenterthestoveatacontrolledrate.Itregulates
theburnrateofthefireandkeepsitataconstantheatoutput,irrespectiveofthefuelload(solongasitisn’t
empty)Whenwantingtocontrolthestoveusingthethermostaticcontrol,theprimaryandsecondaryair
controlscanbeshut.

Accordingtothechosenpositionofthethermostatdial,thedamperwillreactslowlyandalterthecombustible
airenteringtheunit.Thisishowafirewouldnaturallyrespondtochangingairsupply.

Asitisahighprecisiondevicewerecommendmovingtheleverslowlyandwithcareandneverforcingit.

Thethermostatcontrolmustnotbeusedtobuildthefireupsuddenlyandthenshutitdownsuddenly.Thisis
ofnobenefitandmaycauseseriousdamagetotheinternalcomponentsoftheapplianceorcontrol.

4DDirectFluePathShutterControl(leverC)

Thiscontrolisusedtobypassthebafflewithin
thestovewhenthereisariskofthechimney
beingcoldandthereforegeneratinglittle
draw;whenthestovehasnotbeenlitfor
sometimeforexample.Thefluemayneeda
littleassistanceandtherefore,iftheshutteris
openedbeforethefireislit;thewarm/hot
gassesfromthefirewillnothavetotravel
aroundthebaffle,losingheatastheygo.They
cangodirectlyintothechimneywherethey
willheatthechimneyandthusgeneratea
goodfluedraft.

5.FUELOPTIONS

Theseapplianceshavebeendesignedtoburnwoodastheirprimaryfuelsource.Donotburnwoodthat
containschemicals(e.g.paintandglue).Youneedtousewellseasonedwoodtogetthebestresultsfrom
yourstove,logsshouldhaveamoisturecontentoflessthan20%.

5A BURNINGWOOD

Hardwoodsandsoftwoodsbothhavethesamecalorificvalue(byweight),howeversoftwoodswillburnnearly
twiceasfastashardwoods.Mostfirewoodyoupurchasewillbegreenandhaveafairamountofwater
content.Itwillneedtobestoredinawellventilatedsheltertoseasonit.
Woodusedinthisappliancemusthaveamoisturecontentoflessthan20%.Damporwetwoodwillquickly
formtardepositsonalltheinternalareaswherethecombustiblegassestravel.Theywillcoatthechimney/flue
withtarandsootthereforeincreasingtheriskofachimneyfire..Alwaysusegoodqualitywood,storeitunder
coverinawellventilatedarea.
Avoidburningoakbark,asthisformstarataveryfastrate.
Whenselectingwood,alsotakeintoconsiderationeaseofsplitting,easeofignitionandburning,howmuch
smokeitproducesandits"coaling"qualities."Coaling"referstotheabilityofaspeciesofwoodtoformalong‐
lastingbedofhotcoalswhenburned.Coalingqualitiesimprovewithhigherdensity.

5CHotPlateOperation

Tooperateyourhotplateonyourstoveliftthehotplatecoverupwards,alwaysusingtheglovesupplied,until
thecatchattherearislockedintoplace,topreventthecoverfromfalling.Tolowerthehotplate,releasethe
catch(usingthetoolsupplied)andslowlylowerthehotplatecoverbackintoplace,usingtheglovesupplied.
Familiariseyourselfwiththisoperationwhilstthestoveiscold.

6.0INITIALBURNINGANDCURINGOFTHEAPPLIANCE

Thefirsttimethattheapplianceislit,therewillbeanodourgivenoff.Thisisthecomponentsoftheappliance
curing.Itwillbenecessarytoventilatetheroominwhichtheapplianceissited.
Thefirstfiringneedstobedonecarefullytoallowallofthecomponentsoftheappliancetosettlegradually.
Nevertrytoruntheapplianceflatoutthefirsttimeyoulightit.
Graduallybuilduptheoutputofthefiresothatnosuddenstressesareputonthecomponentsofthe

6A.USINGYOURSTOVE‐IMPORTANTNOTES:

•Seriousdamagecanresultiftheapplianceisleftrunningwiththeaircontrolsfullyopenfor
extendedperiods.
•Makesurethatnoneofthedoorsareleftopenwhiletheapplianceisinoperation.
•Neverleavetheapplianceunattendedduringtheinitiallightingsequence.
•Donotattempttoopenthedoorimmediatelyafterignitingthefire.Thiscouldcauseaflameflash
out.
•Alwaysweartheprotectivegloveswhenoperatingtheappliance.
•Neverburnenhancedfuelssuchas‘Petrocoke’
•Donotoverloadtheappliancewithfuel.
•Neverusechemicalsorfluidssuchasgasoline,charcoallighter,drainoilorkerosenetolightafire.
•Usingtheapplianceonaverylowoutputwillcauseexcessiveamountsoftartobuildupinsidethe
flueandcanbeaseriousfirerisk,asthiswillfuelachimneyfire.
•Weadvisethatyouhavetheapplianceservicedannuallybyacompetentheatingengineerbefore
thebeginningofanewheatingseason.

7.0LIGHTINGANDMAINTAININGALOGFIRE
Allchimneysandfluesactdifferently.Afterawhile,youwillfindouthowyourunitworksbestforstarting.
•Usescruncheduppaperanddrykindlingtostartthefire.Laytheseonthegrate.
•Opentheprimaryandsecondaryaircontrols.Thethermostatcontrolshouldbesettonumber5.
•Theignitioncontrolshouldbepushedin.Thiswillopenthedampertothechimneyfullyandcreatethe
bestconditionforthelightingofthefire.
•Itwilltakeafewminutesforthefiretoestablishitself.
•Whenthefireisburninghot,addsmallpiecesofhardwood.
•Keepallthedraftcontrolsfullyopentillabedofhot,glowingembersisestablished.
•Onceyouhavesomeredhotburningembers,openthedoorandraketheembersevenlyoverthe
gratebeforeaddinglargerpiecesofwood.
•Wesuggestthatyoudonotfullyloadtheapplianceuntilyouhavebecomecompletelyfamiliarwith
theoperationofALLthecontrols.
•Forbestresults,inanidealsituation,opentheprimaryaircontrolonethirdopenandthesecondaryair
controlcompletelyopen.Theoutputoftheappliancecannowbecontrolledusingthethermostat
control.ThisiswhenburningLOGS.
•Donotopentheloadingdoortooquicklywhenreloadingtheapplianceasthiscancauseflamesto
flashoutthedoor.Thisoccurswhenthereisunburnedfuelandalargeamountofgasesinthetopof
thefirebox.Whenthedoorisopened,oxygeniscombinedwiththegasesandtheseignite,causinga
‘miniexplosion’.
•Themaximumsizeoflog,whenrefuellinganestablishedfire,shouldbe30cm’slongand30‐40cm’sin
circumference.
•Donotburnpaintedorvarnishedwoods,MDF,oakbarkorwoodwithmorethan20%humidity.

8.0ASHREMOVAL

•Theremovaloftheashesshouldbedonewhentheapplianceiscold.
Ashesmustberemovedperiodicallyforthecorrectandefficientoperationofyourappliance.
Donotwaittilltheashpan'scompletelyfull.Thefrequencyofthisashremovalwilldependonthefuelbeing
burned,ie.Softwoodorhardwoodastheycreatedifferingamountsofash.
Keepinmindthatcleaningyourapplianceboostsitsefficiency,asash,sootortardepositswillblocktheheat
fromcomingoutoftheapplianceandthehob.
Excessashinthepancancausethefiretogooutandmayalsocauseseveredamagetoyourgrates.Itwillalso
blockthedampercontrollocatedattherearoftheashpanchamber.
Ifthereisashinsidetheashpanchamber,thiswillalsoneedremoving.Ifnotremoveditmaygetpushedinto
thedampercontrolaperture;locatedattherearoftheashpanchamber;preventingthethermostatcontrol
fromworkingcorrectly.Periodicalinspectionisrecommended.
Takecarewhenremovingtheash,assmallbitsofhotemberscanstaydormantforlongperiodswhenburied
inashes.Thesewillthenflareupagainwhenexposedtooxygen,someknowledgeofproperashremovalis
requiredforsafety.Herearetheimportantpoints:
Removeashestoametalcontainerusingasmalltrowel.Nevervacuumtheashesunlessitisagenuine
‘AshVac’.Thisisavacuumyoucanbuyathearthshops,itisspecificallydesignedforashremoval.

9.0WOODASHDISPOSAL

Thebestthingtodowithyourashesistoputtheminyourgarden.Woodashesarehighinpotassium,calcium,
sodium,magnesium,andphosphorus.
Woodashwillmakeyoursoilmorealkaline,soapplyitappropriatelyforyoursoil.
Inareaswhereofhighrainfall,thisisabenefitbecausethesoilstherearetypicallyacidic.
Dryareastendtohavemorealkalinesoil,soaddingwoodashmightbeaproblem.

Ifyouhavenogarden,youcandisposeofcompletelycoldashwithyourhouseholdtrash.
Placeitinatightlyclosedbagtokeepitcontained.

10.0OPERATINGINTRANSITIONPERIODS(Summer)

Whentheoutsidetemperaturegetstobemorethanthetemperaturewithintheproperty,thereisastrong
possibilityoftheflueworkinginreverse.Iftheapplianceisnotlit,thiswillcausethedraughtoftheflueto
travelinadownwarddirectionandthesmellofsmokewillbeobviousintheroom.
Ifyouexperienceproblemslightingtheappliancebecauseofthegreateroutsidetemperature,thenitwillbe
necessarytowarmthefluebeforeloadingtheappliancewithkindling.Therearevariousmethodsforthis
procedure.Askyourlocalsupplierorregisteredchimneysweepforadvice.
Ifthefireislit,theheatoutputoftheapplianceisoftenreducedandtheexhaustgasesmaynotcomeoutthe
chimneycompletely.Thiscancausethemtocomebackintotheroom.
Inthiscase,
•shaketheembersmorefrequently,
•increasetheairforcombustionand
•onlyloadareducedquantityoffuel.
Thiswillhelptokeepthechimneyhotandworkingefficiently.
Checkthatallthesealsoftheapplianceareingoodorderandthattheconnectionstothechimneyarealso
sound.
