What factors can accelerate the deterioration of a furnace chimney flue?
• Gas Heat: The high volume of water vapor in gas heat exhaust increases deterioration. • An Adjacent Laundry Room: Vapors from chlorine and other cleaning products can enter the chimney through the combustion chamber of the furnace, the draft hood of heating appliances, or the draft regulator on the smoke pipe. • A Nearby Workshop: Again, vapors from solvents can be drawn into the chimney liner.
