• Increase chimney height.
• Increase chimney height.
• 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.
16.
• 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.
• Opening the door has provided
additional oxygen which has
ignited the accumulated gases
from partially spent fuel.
• Always open the door cautiously and allow the safety latch system
to perform its designed function, containing gases within the fire
chamber.
Possible Causes:
Remedies:
17.
• Insufficient natural draft or an
obstruction in the flue system.
• See #8, #9 and #16.
• Fire chamber filled to capacity
with unburned fuel.
• 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 7.
• Wood being used is not dry
enough to produce higher BTU’s.
• Use hardwood that is covered and protected from the weather for at
least a year. Avoid using rotten or poor quality wood.
• Outside air is being pulled
through the return air duct, thus
reducing the temperature of the
heat supply.
• Check the return duct and blower housing for holes and cracks, and
seal with aluminum tape.
• Fan limit control is not set to
factory specifications.
• Set fan limit to 150° as high limit, and 100° as the low limit.
