Limiting Creosote Build Up

Creosote is the technical name for soot. It’s essentially unburned fuel formed when flue gases are too cool and condense into a grimy buildup. Creosote is very flammable, which is why chimney sweeping is necessary. One way to minimize creosote buildup is to properly prime your fireplace by burning balls of newspaper before attempting to start a wood-burning fire. When the smoke from the paper fire disappears, your chimney is sufficiently primed and any cold air pockets have been expelled. This will keep the flue gases too hot to be able to condense into creosote.
