9. Problem: Down draft on chimney caused by one or more of the following.

Possible Causes:


• Flue has a cold spot which inhibits exhaust discharge from rising properly.

• This problem may occur in factory built flues because the insulation has settled or a seam has ruptured. In masonry flues, mortar loss may be causing seepage of cooler outside air into the stack. Check entire flue for structural integrity and leakage. Correct or repair as needed, or replace or re-line the chimney.

• There is an obstruction outside the chimney, such as a tree. • Flue is located too close to the peak of the roof or does not rise above it to provide the proper draft.

• Remove obstruction.

• Increase chimney height.
