Creosote can be a problem in any wood-burning appliance. Creosote is a black, foul smelling liquid that
results from distillation of wood gases during the combustion process. It solidifies depending on temperature
and in either state is highly combustible. The best way to prevent or minimize creosote build up is to follow
proper firing methods. The amount of creosote depends on several factors that include:
1) Moisture content of the fuel
2) Stack or flue temperature
3) Amount of draft
4) Efficiency of the appliance
5) Turbulence of smoke
.
At stack temperature below 120
°
C (250
°
F), the creosote will condense out of the gasses (smoke). Once a
flue pipe becomes heavily coated with creosote, the only safe way to remove it is mechanically with a proper
chimney cleaner or brush. A combination of wet fuel and poor operating procedure may necessitate weekly
cleaning to remove creosote buildup.
Remember - the hotter the fire the less creosote. Small intense fires create less creosote than large,
smoldering fires. We recommend that each day a small intense fire be built, preferably in the morning. This
daily practice should burn out the small deposits of creosote before they build to a dangerous level. The
combustion air inlet should be opened for at least 30 minutes by turning the thermostat up in the morning and
evening. NEVER "burn out" large deposits of more than one days accumulation.
Always assure safety by having a clearly understood plan of how to handle a chimney fire, should one occur.
In conclusion, creosote can best be controlled as follows:
1. Burning dry split wood.
2. Mixing small and large pieces of wood.
3. During warm weather using smaller split wood.
4. Establish a routine for the storage of fuel, care of the appliance, and firing techniques.
5. Keeping stack temperature up by using double wall pipe on flue runs and
protect outside chimney installations in a chase. Minimize elbows and keep
flue runs as short as possible and ensure tight connections.
6. Checking daily for creosote until experience shows how often cleaning is required. Remember a
clean chimney is a safe chimney.
7. Having a clearly understood plan should a chimney fire occur.
