SAFETY CONSIDERATIONS
IMPORTANT SAFETY CONSIDERATIONS
Solid fuel exhaust contains creosote and other substances that accumulate in ducting, creating a risk of fire� The rate
of accumulation will vary with respect to flue gas temperature, wood type and moisture content� Frequent, regularly
scheduled, thorough flue cleaning is the best way to minimize the risk of flue fires�
CREOSOTE - AND THE NEED FOR ITS REMOVAL
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 oven flue of a slow-burning fire� As a result, creosote
residue accumulates in the duct� When ignited, this creosote makes an extremely hot fire� The duct serving this oven
should be inspected at least twice a month during the first two months of operation, to establish rate of creosote buildup
and necessary cleaning schedule� If creosote or soot has accumulated, it should be removed to reduce the risk of a flue
fire� The interior floor and dome of the oven do not require creosote or soot removal�
The oven flue and exhaust system will require inspection and cleaning� The exhaust system should be inspected and
cleaned per the manufacturer’s and or local code official’s recommendations�
Wood Stone recommends cleaning and
inspection at least monthly on any ventilation system serving solid fuel equipment.
