3.2.1 WHATISGOODFIREWOOD?
Good firewood has been cut to the correct length for the insert, split to a range of sizes and
stackedintheopenuntilitsmoisturecontentisreducedto15to20percent.
3.2.2 TREESPECIES
The treespecies the firewood is pr oduced from
isless important than its moisture content. The
maindifference infirewoodfromvarioustreespeciesisthedensityofthewood. Hardwoodsare
denserthansoftwoods.PeoplewholiveinthecoldestregionsofNorthAmericausuallyhaveonly
spruce, birch and poplar, other lowdensity species to burn and yet they can heat their homes
successfully.
Homeowners with access to both hardwood and softwood fuel sometimes use both types for
differentpurposes.Forexample,softerwoodsmakegoodfuelforrelativelymildweatherinspring
andfallbecausetheylightquicklyandproducelessheatSoftwoodsarenotas
denseashardwoods
so a givenvolumeof wood containsless energy. Using softwoods avoids overheatingthe house,
whichcanbeacommonproblemwithwoodheatinginmoderateweather.Harderwoodsarebest
forcolderwinterweatherwhenmoreheatandlongerburncyclesaredesirable.
Notethathardwoodtreeslikeoak,maple,ashandbeechareslowergrowingandlongerlivedthan
softer woods like poplar and birch. That makes hardwood trees more valuable. The advice that
MatrixInsertInstallationandOperationManual
14______________________________________________________________________________
only hardwoods are good to burn is outdated. Old, leaky cast iron stoves wouldn’t hold a fire
overnight unless they were fed large pieces of hardwood. That is no longer true. You can

3.2.5 HOWTODRYFIREWOOD
Firewood that is not dry enough to burn is the cause of most complaints about wood inserts.

Thisinserthasbeentestedforusewithanopendoorinconjunctionwithafirescreen(AC01315,

sparksdamagingyourflooring.Whenthefirescreenisinuse,donotleavetheinsertunattended
sothatyoucanrespondpromptlyintheeventofsmokespillageintotheroom.Potentialcausesof
smoke spillage are described in Section 9 The Venting System of this manual. See Appendix 6:
InstallingtheFireScreen(AC01315)forinstallationinstructions.
OPERATING WITH THE FIRE SCREEN INCREASES POSSIBILITIES OF GENERATING CARBON
MONOXIDE. CARBON MONOXIDE IS AN ODOURLESS GAS THAT IS HIGHLY TOXIC AND WHICH
CANCAUSEDEATHATHIGHCONCENTRATIONINAIR.
4.2 YOURFIRSTFIRES
Two things will happen as you burn your first few fires; the paint cures and the internal
componentsoftheinsertareconditioned.
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 insert, 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 insert. Once the paint smell
disappears,yourinsertisreadyforseriousheating.
4.3 LIGHTINGFIRES
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 chimney. Here are three popular and
effectiveways
tostartwoodfires.
MatrixInsertInstallationandOperationManual
18______________________________________________________________________________
4.3.1 CONVENTIONALFIRESTARTING
Theconventionalway tobuildawood fire
is to bunch up 5 to 10 sheets of plain
newspaper and place them in the firebox.
Next,place10orsopiecesoffinekindling
onthenewspaper.Thiskindlingshouldbe

some larger kindling pieces on the fine

light the newspaper. If you have a tall,

4.4 MAINTAININGWOODFIRES
4.4.1 GENERALADVICE
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
theseareadvantagesofzoneheatingwithwood.
Donotexpectsteadyheatoutputfromyourinsert.Itisnormalforitssurfacetemperaturetorise
after a new load of wood is ignited and for its temperature to gradually decline as the fire
progresses.Thisrisingandfallingoftemperaturecanbematchedtoyourhouseholdroutines.For
example,theareatemperaturecanbecoolerwhenyouareactive,suchaswhendoinghousework
or cooking, and it can be warmer when you are inactive, such as when reading or watching
television.

atimesothatthe heatradiatedfromonepiecehelpstoignitethepiecesnexttoit.Eachloadof
wood should provide several hours of heating. The size of each load can be matched to the
amountofheatneeded.
When you burn in cycles, you rarely need to open the insert’s loading door while the wood is
flaming. This is an advantage becausethere ismore chance that smoke willleak fromthe insert
whenthedoorisopenedasafullfireisburning.
