A. Chimney Systems
Achimneyoruesystemisrequiredtorunyourwoodstove
safelyandefciently.Whenareisstartedintherebox
hotgasesarereleasedandexitthereboxintothechimney
system. These hot gases heat up the chimney system and
createavacuuminthereboxorcommonlyreferredto
asdrafting.Asaresult,moreairispulledintotherebox
through the air openings. When more air is pulled into
there,thereburnshotterandisacleanerburn.This
also means that the burn time is shorter but more heat
is generated to heat the living space and the glass stays
cleaner. When the air controls are adjusted and reduced,
therewillslowdown.Thislowersthedraftandasa
result, the burn times are longer.
When lighting the appliance, it is important to get a hot
reasquickaspossibletoestablishthedraftinthesystem
foranefcientandcleanburn.Therearemanydifferent
types of chimney systems, check with your local authority
for more details and follow all regulations in your area.

B. Drafting
Weather and chimney location can affect the draft of your
stoveresultingindifferentperformancesettings.Forwindy
conditions, the draft may be higher which will result in
changing the air control settings for the same performance.
In areas where high wind is common, a damper may need
tobeinstalledintheuepipetobestcontroltheappliance.
Performancecanalsobeinuencedbychangesinhumidity
includingfog.Adjusttheaircontrolsasneededtoachieve
the desired heat output of your Curve wood burning stove.
