Problem Solution
POOR DRAFT: Extend chimney in length or have the chimney realigned to the proper size flue. Oversized chimneys normally have
poor drafts. Remember, the stove or fireplace inserts’ draft depends solely on the natural draft of the chimney (See
Draft Requirements on Page 4). If your stove or fireplace insert is not drafting properly, your chimney is the problem.
All stoves are thoroughly tested to ensure proper draft with the correct size chimney flue.
EXCESSIVE DRAFT: With better chimneys being more common, excessive draft can be an issue. Alleviate excessive draft by slowing the
burn rate of the stove or fireplace insert once it has reached proper operating temperature (See Maximizing Your Stoves
Overall Efficiency on Page 21).
DIRTY GLASS: 1) Burn smaller, hotter fires and check to make sure you are not setting the draft down too far with the draft control.
2) Make sure your wood is well-seasoned and dry (not open to rain - see Creosote [Page 24] and Fuel [Page 20] sec-
tions).
3) See Poor Draft section (above) and Cleaning Glass on Page 24.
SMOKES WHEN 1) If smoke is entering the room, check to make sure your baffle boards are properly installed.
DOOR IS OPEN: 2) Check the chimney for blockage due to creosote (see Chimney [Page 6] and Creosote [Page 24] sections).
3) Check draft (See POOR DRAFT section above).
WOOD BURNS 1) The draft control must be closed further.
TOO FAST: 2) Add fuel at lower firebox temperatures.
3) Load wood side to side and reduce the flow of air under wood.
4) The door seal may need replacing, check for leakage.
5) See “Excessive Draft.”
POOR HEAT OUTPUT: 1) Check your wood. Wet, moist, unseasoned wood will not produce heat.
2) Your stove or fireplace insert needs to be seasoned (moisture removed from the steel and brick). Continue to burn a
fire. It normally takes from one to three weeks of burning to season your stove (See Burn-In procedures on Page 18).
3) See Excessive Draft section above.
PAINT GIVES OFF Paint is tempering-in. Burn only moderately hot for the first few days until paint is fully cured.
ODOR (smoke): Then burn a very hot fire to cure any paint that may not easily cure. Open windows or door to ventilate (See Burn-In
Period on Page 18).
