Problem: Down draft on chimney caused by one or more of the following. 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.
• 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. • Flue is too close to another building.
• Remove obstruction.
• Increase chimney height.
• Increase chimney height.
• Check entire chimney system including stove pipe run. Utilize chimney cleaning device to remove any obstruction or foreign matter. • Remove as necessary.
• Obstruction in chimney.
• Excessive ash accumulation. Problem: Flames discharging from fuel door during reloading.

Remedies:
Possible Causes:
• Opening the door has provided additional oxygen which has ignited the accumulated gases from partially spent fuel. • Insufficient natural draft or an obstruction in the flue system. • Fire chamber filled to capacity with unburned fuel.
• Always open the door cautiously and allow the safety latch system to perform its designed function, containing gases within the fire chamber.
• See #8, #9 and #16.
• Do not attempt to overload the furnace.
Problem: The air coming out of heat registers is not warm enough. Possible Causes: Remedies: 18. • The chimney on the furnace is not tall enough which is affecting the efficiency of the furnace.
• Add additional sections of chimney to the flue to ensure compliance with the “10/2 Rule.” See diagram on page 4.
• Wood being used is not dry
• Use hardwood that is covered and protected from the weather for at least a year. Avoid using rotten or poor quality wood. • Check the return duct and blower housing for holes and cracks, and seal with aluminum tape.
enough to produce higher BTU’s.
• Outside air is being pulled
through the return air duct, thus reducing the temperature of the heat supply.
• Fan limit control is not set to factory specifications.
• Set fan limit to 160° as high limit, and 100° as the low limit.
