Your chimney liner is arguably the most important component of your chimney and flue system.  It is extremely important the chimney liner is intact and in good condition whether it is for your fireplace, furnace, wood, pellet, or gas stove.

Your chimney liner has 3 main priorities.

1. Create an air tight flue system
   Your liner is responsible for exhausting not only the dangerous products of combustion like carbon monoxide and carbon dioxide but it also must contain all flames, sparks and heat.
2. Insulate against high temperatures
   Your chimney system can be exposed to temperatures above 2000 degrees Fahrenheit at times (as hot as molten lava).  Since the brick and mortar your chimney is built from is extremely dense (like a frying pan) the high temperatures can conduct through the bare brick to catch nearby combustibles on fire. Your chimney liner is responsible for insulating against this heat to stop thermal conduction through the chimney walls.
3. Protect masonry against acids and moisture  
   The products of combustion with any type of fuel is extremely corrosive and full of condensation.  Combustion exhaust almost always has an acid base and lots of moisture. This constant exposure to moist conditions and an acidic environment will corrode and erode the interior brick and masonry causing premature deterioration and compromise the integrity of the flue system. Your flue liner is responsible for protecting the masonry from these hazardous conditions.
