ing, or once every two months during heating season.

• When wood is burned slowly, it produces tar and
other organic vapors, which combine with expelled
moisture to form creosote. The creosote vapors
condense in the relatively cool chimney flue of a
slow-burning fire. As a result, creosote residue
accumulates on the flue lining. When ignited, this
creosote makes an extremely hot fire.
• Remove all ash from the firebox and extinguish all
hot embers before disposal. Allow the fireplace to
cool completely.
• Remove baffle and ceramic blanket from fireplace
before cleaning chimney (refer to Section 5.C.3 Baffle
Removal and Installation).
• Close the door tightly.
• Remove the top of the termination cap as shown in
Figure 4.1 to clean the cap and chimney.
• The creosote or soot should be removed from the
chimney with a brush specifically designed for the
size of chimney in use.
• Reinstall termination cap.
• Clean out fallen debris from the firebox.
