Problem: Down draft on chimney caused by one or more of the following.
• Cast iron damper in “CLOSED”
position.
• Open damper.
Possible Causes:
Remedies:
• 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.
• Remove obstruction.
• Increase chimney height.
• Open backdraft damper.
• There is an obstruction outside
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.
• Backdraft damper is in the
“closed” position.
