C. Fuel
1. Hardwood vs. Softwood
Yourreplace’sperformancedependsonthequalityof
therewoodyouuse.Onespeciesofwoodvariesvery
little to the other in terms of energy content.All sea-
soned wood contains about 8,000 BTU’s per pound.
Hardwoods have a greater density than softwoods; a
pieceofhardwoodwillcontainabout60%moreBTU’s
than an equal size piece of softwood.A cord of sea-
sonedoak(hardwood)wouldcontainabout60%more
potential energy than a cord of seasoned pine (soft-
wood).
Most softwoods are coniferous. These are trees with
needle-like leaves that stay green all year and carry
their seeds exposed in a cone. Examples of conifer-
oustreesareDouglasr,pine,spruceandcedar.Soft-
woods, being more porous, require less time to dry,
burn faster and are easier to ignite than hardwoods.
Hardwoods are deciduous trees, broadleaf trees that
lose their leaves in the fall. Their seeds are usually
foundwithin a protectivepod or enclosure.Some ex-
amplesofdeciduoustreesareoak,maple,apple,and
birch.However,itshouldbenotedthattherearesome
deciduoustreesthataredenitelynotconsideredhard-
woods such as poplar, aspen and alder. Hardwoods
requiremoretimetoseason,burnslowerandareusu-
allyhardertoignitethansoftwoods.Obviously,youwill
usethe type ofwood that ismost readily availablein
yourarea.However,ifatallpossiblethebestarrange-
mentistohaveamixofsoftwoodandhardwood.This
wayyoucanusethesoftwoodforstartingthere,giv-
ingoffquickheattobringthereplaceuptooperating
temperature.Addthehardwoodforslow,evenheatand
longerburntime.
2. Moisture content
The majority of the problems replace owners expe-
rienceare caused by trying to burn wet, unseasoned
wood.Freshlycutwoodcanbeasmuchwaterasitis
wood,havingamoisturecontentofaround50%.Imag-
ineawoodenbucketthatweighsabout8pounds.Fillit
withagallonofwater,putitinthereboxandtrytoburn
it.This sounds ridiculous butthatisexactly what you
are doing if you burn unseasoned wood. Dead wood
lyingontheforestoorshouldbeconsideredwet,and
requiresfullseasoningtime.Standingdeadwoodcan
beconsideredtobeabouttwo-thirdsseasoned,ifcutat
thedrytimeoftheyear.
Burningwet,unseasonedwoodwillproducelessheat
outputbecause it requiresenergyin theformof heat
toevaporatethe watertrappedinside.Thisiswasted
energythatshouldbeusedforheatingyourhome.This
moisture evaporates in the form of steam which has
a cooling effect in your rebox and chimney system.
Whencombinedwithtarandotherorganicvaporsfrom
burningwooditwillformcreosotewhichcondensesin
therelativelycoolreboxandchimney.
Even dry wood contains at least 15% moisture by
weight,andshouldbeburnedhotenoughtokeepthe
chimneyhotforaslongasittakestodrythewoodout
-aboutonehour.Totellifwoodisdryenoughtoburn,
checktheendsofthelogs.Iftherearecracksradiating
inalldirectionsfromthecenter,itisdry.Ifyourwood
sizzlesinthere,eventhoughthesurfaceisdry,itmay
notbefullycured.
WARNING! For use with solid wood fuel only.
Otherfuelsmayoverreandgeneratepoisonousgases(i.e.
carbon monoxide).

5. Burning Process
Firerequiresfuel,airandheat.Ifheatisrobbedfrom
thereplace duringthe dryingstage, thenew loadof
woodhasreducedthechancesforagoodcleanburn.
Alwaysburndry,seasonedrewood.
6. Creosote Formation
Whenwoodisburnedslowly,itproducestarandother
organicvaporswhichcombinewithexpelledmoisture
to form creosote. The creosote vapors condense in
the relatively cool chimney ue of a newly-started or
a slow-burning re.As a result, creosote residue ac-
cumulatesontheuelining.
When ignited, creosote creates an extremely hot re
which may damage the chimney or even destroy the
house.
Thechimneyshallbe inspected atleastannually be-
forelighting,oronceeverytwomonthsduringheating
season.
Whencreosotehasaccumulateditshallberemovedto
reducetheriskofachimneyre.
7. Processed Solid Fuel Firelogs
Manufacturedrelogsmaybeusedwiththisreplace.
Hearth&HomeTechnologiesrecommendstheuseof
ULClassiedprocessedfuelrelogs.Followthemanu-
facturer’slightingandsafetyinstructions.
Usingrelogsmayrequire more frequent chimney in-
spectionsandcleaning.
Donotpokeorstirthelogswhiletheyareburning.Use
only relogs that have been evaluated for the appli-
cation in manufactured replaces and refer to relog
warningsand cautionmarkings onpackaging priorto
use.
3. Seasoning
Seasonedrewoodisnothingmorethanwoodthatis
cuttosize,splitandairdriedtoamoisturecontentof
around20%.Thetimeittakestoseasonwoodvaries
fromaroundninemonthsforsoftwoodstoaslongas
eighteenmonthsforhardwoods.Thekeytoseasoning
woodistobesureithasbeensplit,exposingthewet
interiorandincreasingthesurfaceareaofeachpiece.
A tree that was cut down a year ago and not split is
likelytohavealmostashighamoisturecontentnowas
itdidwhenitwascut.
Toseasonwood:
• Cutlogstosize
• Splitto6in.(152mm)orless
• Airdrytoamoisturecontentofaround20%
 - Softwood-aboutninemonths
 - Hardwood-abouteighteenmonths
NOTICE: Seasoningtimemayvarydependingondrying
conditions.
4. Storing Wood
Splittingwoodbefore it isstoredreduces drying time.
Thefollowingguidelinewill ensure properly seasoned
wood:
• Stackthewoodtoallowairtocirculatefreelyaround
andthroughthewoodpile.
• Elevate the woodpile off the ground to allow air
circulationunderneath.
• Thesmallerthepieces,thefasterthedryingprocess.
Anypieceover6in.(152mm)indiametershouldbe
split.
• Woodshouldbestackedsothatbothendsofeach
pieceareexposedtoair,sincemoredryingoccurs
throughthecutendsthanthesides.Thisistrueeven
withwoodthathasbeensplit.
• Storewoodundercover,suchasinashed,orcovered
withatarp,plastic,tarpaper,sheetsofscrapplywood,
etc.,asuncoveredwoodcanabsorbwaterfromrain
or snow, delaying the seasoning process.Avoid
covering the sides and ends completely. Doing so
maytrapmoisturefromthegroundandimpedeair
circulation.

A. FAQs
Ifsmokespillageoccursfromareplaceopeningwhen
thedoorisopen,thereiseitheraleakageintheue,a
blockageintheue,orsomeconditionisaffectingdraft
Understandinganddifferentiatingtheconditionswhich
cancauseeachofthesekindsofspillageproblemsis
essentialtotheirsolution.
• FlueLeakage
 Check for improperly connected flue joints or a
damaged ue joint in the chimney system. Such
leakagewouldreducedraft(airwouldbedrawnin
throughtheleaksratherthanthroughthereplace).
The result might be difficult start-up and smoky
resthatmightspillifotheradversedraftconditions
accompanythisproblem.
• FlueBlockage
 Thedampershouldbeopen.
 Check for objects that may have fallen down the
chimney.
eratinginstructions,“StartingaFire”.Besureyourue

• Allchimneysectionsareproperlyinstalled.
• Thechimney iscleanandfreeofcreosoteor soot
buildup.
• Makesureoverhangingtreesandbranchesarecut
backwithintenfeetofthetopofthechimneyandthe
chimneyisfreeofdebrisfromanimals.
• Ensure the chimney cap is clean and free of any

• Thewoodbeingusedindryandwellseasoned.
Ifyoustillsuspectyouhavealowdraftproblemitmay
be necessary to increase the volume of air in your
uesystem.Sincethediameterofyouruesystemis
matchedwiththesizeoftheuecollarandshouldnot
bechanged,thentheheightofthesystemmustbein-
creased.Addchimneysectionsoneatatimeuntilthe
draftimproves.
Insomecases,regardlessofwhatyoudo,itcanstillbe
difculttoestablishtheproperuedraft.Thisisespe-
ciallyevidentwhenusinganexteriorfactory-builtchim-
neyorexteriormasonrychimney.Tryholdingaburning
rolledupnewspaperasclosetotheueoutletaspos-
sibleforafewminutes,thenlightthepaperunderthe
kindling.Theheatgeneratedfromtheburningrolledup
newspapershouldhelpgetthedraftestablished.
Stillotherfactorscanaffecthowwellyouruesystem
performs.Neighboringstructures,highwinds,talltrees,
evenhillsidescanaffectaircurrentsaroundthechim-
ney.Welldesignedchimneycapsareavailablethatcan
help. Your replace dealer is the local expert in your
area. He can usually make suggestions or discover
problems that can be easily corrected allowing your
replacetooperatecorrectlyasithasbeendesigned,
providingsafeandeconomicalheatforyourhome.
Flue draft is measured as negative pressure in the
chimney.Theamountofnegativepressuredetermines
howstrongthedraftis.Thedraftisimportantbecause
itdrawsthecombustionairintothereplaceandpulls
thesmokeoutofthechimney.
Therearethreebasiccriteriaessentialinestablishing
andmaintaininguedraft:
• availabilityofcombustionair
• heatgeneratedfromthere
• diameterandheightoftheuesystem
Thesethreefactorsworktogetherasasystemtocreate
theuedraft.Increasingordecreasinganyoneofthem
willaffecttheothertwoandthuschangetheamountof
draftintheentiresystem.
Ifthereishardtostartandsmokespillsoutofthere-
place,oryounditdifculttoestablishandmaintaina
moderatelyhighburnrate,thentheuedraftistoolow
andcorrectivemeasuresmustbetaken.
Besureyouhaveairavailableforcombustionandthat
yourrewoodisdryandwellseasoned.Buildyourres
properlyandaccordingtotheinstructionsgiveninop-
