9.5 chimney cleaning
Both the chimney and the appliance must be inspected and cleaned if necessary at least once a year.
For serious wood burners, chimney cleaning must be done as needed to avoid chimney fi res; the venting
systems for controlled combustion appliances may need cleaning as often as once a month. These rates,
however, depend on the burning habits of the individual operating the appliance. For example, it is possible to
clog a solid fuel appliance chimney in a few days if slow, smoldering fi res are burned and the chimney is cold.
Certain items and considerations are important in chimney cleaning:
• Proper tools should be used, including a brush specifi cally designed for chimney cleaning.
• The chimney connector and dampers as well as the chimney should be cleaned.
• The appliance’s fi rebox and baffl e system should be cleaned if needed.
• The chimney should be inspected and repairs made if needed, preferably by a qualifi ed chimney sweep
or mason.
note:
Appliances burned consistently without hot fi res may result in signifi cant creosote accumulations in the
chimney.
• See chimney manufacturer’s installation instructions for cleaning and inspection instructions.
!
WARNING
If cleaning the chimney from the inside of the fi rebox, the secondary air manifold must be removed and the
gaskets replaced using gasket kit W370-0075. See “internal gasket replacement” section for details.
