How to Burn Out Creosote in a Stovepipe
Few things present more of a danger for house fires than creosote buildup in a stovepipe. This black, tar-like substance is released from burning wood. Creosote is composed of unburned wood particles, ash and gases, all of which are highly flammable.
Things You Will Need
+- Firewood
- Powder chemical catalyst
- Liquid chemical catalyst
- Fireplace thermometer
- Chimney or stovepipe brush
When the pipe becomes clogged, heat and smoke move sluggishly and may even get trapped. If an ember flies up into the pipe, a fire is likely. Thus, the moment you notice creosote, it must be removed.
-
Light a fire in the stove using only very dry wood; this produces very little creosote and very hot temperatures. Keep an eye on your temperature, as you need it to be above 300 degrees F.
-
Once the fire gets going, puff in the powder chemical catalyst above the flames, following the instructions on the bottle. This product is available at most home improvement stores.
-
Repeat this process for about two weeks, making a fire as often as possible during that time.
-
After two weeks, attempt to brush out the creosote.; it should have broken down to a form that an ordinary brush will remove. If not, repeat the process another week. Severe cases may take more than a month to clear.
-
Each time you have a fire after removing the creosote, spray a few pieces of firewood with a liquid chemical catalyst. Follow the instructions on the bottle.
Tip
Don't be afraid to call a professional inspector and cleaner. Some severe cases may require this, as a professional has access to stronger catalysts not available on the market.
Warning
Do not attempt this if your stovepipe is more than 75 percent clogged. Call a professional instead.
Use proper safety measures when handling the catalysts and the fire. Do not leave the fire unattended.
