What must the chimney lining be appropriate for?

The chimney lining must be appropriate for the type of fireplace, stove, heating system, or appliance because different heating sources produce various types and amounts of gases, heat, and particulate matter. Each type of system has different requirements for safe venting. The lining material must be compatible with the type of fuel being burned, whether it is wood, gas, or oil, to prevent issues such as flue gas condensation, which could lead to corrosion or a chimney fire.

For example, wood-burning fireplaces require a different lining than gas appliances due to the higher temperatures and creosote production associated with burning wood. A proper chimney liner also ensures efficient venting of the combustion gases and protects the chimney structure from heat and corrosion, which ultimately promotes safe operation and reduces the risk of fire hazards. Thus, it is essential that the chimney lining is specifically matched to the type of appliance it serves to ensure safety and efficiency.
