Creosote - Formation and Need for Removal -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slow-burningre.Asaresult,creosoteresidueaccumulatesontheuelining.Whenignited,thiscreosotemakesan
extremelyhotre.Thepelletventpipeshouldbeinspectedatleasttwicemonthlyduringtheheatingseasontodetermine
ifacreosotebuilduphasoccurred.Ifcreosotehasaccumulateditshouldberemovedtoreducetheriskofachimneyre.
Guidanceonminimizingcreosoteformationandtheneedforperiodiccreosoteremoval:Thechimneyshouldbeinspected
duringtheheatingseasontodetermineifacreosotebuild-uphasoccurred.Ifasignicantlayerofcreosotehasaccumulated
(3mmormore)itshouldberemovedtoreducetheriskofachimneyre.
