CREOSOTE - Formation and need for removal
When wood pellets are burned slowly, they produce tar and other
organic vapors that combine with expelled moisture to form creo-
sote. The creosote vapors condense in a relatively cool oven flue
and exhaust hood of a slow burning fire. As a result, creosote residue
accumulates on the flue lining and exhaust hood. When ignited, this
creosote makes an extremely hot fire.
The grease duct should be inspected at least monthly to determine
when grease and/or creosote buildup has occurred.
When grease or creosote has accumulated, it should be removed to
reduce risk of fire.
When Creosote, or soot, is burning, it produces black smoke and
leaves a residue which is also black in color. Soot or creosote is
formed when the appliance is operated incorrectly, such as: blockage
of the combustion fan, failure to clean and maintain the fire pot area,
or poor air-to-fuel combustion. It is dangerous to operate this appli-
ance should the flame become dark and sooty. When ignited, this
creosote will result in an extremely hot and uncontrolled fire, similar
to a grease fire. Should this happen, turn the appliance OFF, let it
cool completely, then perform maintenance and cleaning. Creosote
commonly accumulates along exhaust areas, and other areas where
smoke can escape. If creosote has formed inside the appliance; allow
the appliance to warm up at a low temperature, turn off the appliance,
then wipe away any formation with a hand towel. Similar to tar, it is
much easier to clean when warm, as it becomes liquid.
