Flame Appearance and sooting
Proper.flame.appearance.is.a.flame.which.is.
blue.at.the.base.and.becomes.yellowish-orange.
in.the.body.of.the.flame...When.the.appliance.
is.first.lit,.the.entire.flame.may.be.blue.and.will.
gradually.turn.yellowish-orange.during.the.first.
15.minutes.of.operation..After.15.minutes.of.
operation,.if.the.flame.is.blue,.or.if.the.flame.is.
orange.with.evidence.of.sooting.(black.tip),.the.
air.shutter.opening.may.need.to.be.adjusted.
If. the. air. shutter. opening. is. closed. too. far,.
sooting.may.develop..Sooting.is.indicated.by.
black.puffs.developing.at.the.tips.of.very.long.
orange.flames...Sooting.results.in.black.deposits.
forming.on.the.logs,.appliance.inside.surfaces.
and.on.exterior.surfaces.adjacent.to.the.vent.
termination...
Sooting.is.caused.by.incomplete.combustion.in.
the.flames.and.lack.of.combustion.air.entering.
the.air.shutter.opening..To.achieve.a.warm.yel-
lowish-orange.flame.with.an.orange.body.that.
does. not. soot,. the. shutter. opening. must. be.
adjusted.between.these.two.extremes..
Air Shutter Adjustment Guidelines
•. If.there.is.smoke.or.soot.present,.first.check.
the. log. set. positioning. to. ensure. that. the.
flames.are.not.impinging.on.any.of.the.logs.. .
If.the.log.set.is.properly.positioned.and.a.
sooting. condition. still. exists,. then. the. air.
shutter.opening.should.be.increased.
•. The.more.offsets.in.the.vent.system,.the.larger.
the.air.shutter.opening.will.need.to.be.
•. An.appliance.operated.with.the.air.shutter.
opened.too.far,.may.have.flames.that.appear.
blue.and.transparent...These.weak,.blue.and.
transparent.flames.are.termed.anemic..
•. Propane.models.may.exhibit.flames.which.
candle.or.appear.stringy..If.this.is.present.
and.persists,.adjust.the.air.shutter.to.a.more.
closed.position,.then.operate.the.appliance.
for.a.few.more.minutes.to.ensure.that.the.
flame. normalizes. and. the. flames. do. not.
appear.sooty..
The.following.chart.is.provided.to.aid.you.in.
achieving. the. correct. air. shutter. adjustment.
