A Quick Understanding of Chimney Liners

   A chimney needs a liner when:

a) The chimney is older and lacks clay tiles through the flue.

b) The clay tile liner is damaged.

c) A reduction of the passage is required in the installation of 
    newer, high efficiency units.

   But the most important reason a chimney needs a liner is safety. 
   Clay tile deteriorates over time, especially in uncapped oil flues where water combines with oil soot, producing an acidic reaction that literally eats away at the tile and compromises its structure. 
   Given enough time, tiles can collapse and block the passage, forcing toxic fumes to leak into the home.
   Yearly inspections are paramount in identifying potential hazards. The presence of tile flakes accumulated at the bottom of the flue is a clear sign a problem needs to be addressed, and can only be identified with regular yearly inspections.
   We highly recommend the installation of smoke and carbon monoxide to alert you to any fume leakage.
   According to the Chimney Safety Institute of America, studies performed on masonry chimneys in the 1980's by the National Bureau of Standards for durability due to the rising concerns about performance and safety, revealed that unlined chimneys were so unsafe that researchers characterized building a chimney without a liner as "little less than criminal." 
Chimney liners are not exclusive to furnaces. 
   To properly vent a wood stove, current building codes require the installation of an insulated liner to ensure the passage doesn't allow for the quick condensation and eventual solidification of creosote. 
  Reliable chimney professionals know how to size the home for the proper liner system and will adhere to the manufacturer's specific installation guidelines for every situation. Chimney liner warranties require that the installation is done by a qualified chimney professional and for the liner to be inspected annually.
