Using the CSL with a woodstove or fireplace insert
Woodstoves are well known to produce high amounts of creosote inside the flue pipes.
Burning only one CSL in a wood stove or fireplace insert will reduce overall creosote weight, thickness & volatile organic compounds. Therefore, to keep your woodstove or fireplace insert in good condition, follow the guidelines in the chart below according to your woodstove or fireplace insert usage.

Creosote build-up will depend on appliance type, fuel used, frequency of use and other factors.
For Woodstoves, inserts and small fireplaces, use 1 CSL at a time:
Regular chimney inspections are always recommended. The CSL will not tell you if your chimney is blocked or has any kind of structural damage. The CSL does not take the place of inspection and professional cleaning.
