Early Times Chimney Sweeps- Liners

The National Fire Protection Association Code 211 requires that all masonry chimneys have a liner. The liner is the passageway in the fireplace or furnace flue through which gases and smoke travel in order to escape your home. The liner separates the fireplace or the furnace system from the rest of your house.

	A LINER IS NEEDED WHEN...
	The following is a list of a few situations in which a liner is needed: You have an unlined flue. There is a liner, but it is improperly sized or the integrity of the structure is compromised. (Cracked tiles, missing mortar joints) You’ve updated your furnace system to a more efficient one, and you have not had a new appropriately sized liner installed. You see efflorescence, a whitish discoloration on the exterior of your furnace chimney. You see condensation near the base of the furnace and the water heater pipes.

	TYPES OF LINERS
	A Stainless steel liner is recommended for lining almost all types of flues, fireplace, and furnace and water heater. An Aluminum liner is suitable for lining many furnace and the water heater flues, provided that neither oil nor coal has ever been burned in the system. A Clay tile liner is most commonly found in older homes with masonry fireplaces.
