5.10 Creosote Formation and the
Need for Removal
When wood is burned slowly, it produces tar and other
vapors that combine with moisture to form creosote.
Creosote vapors condense in the relatively cool chimney
flue, and creosote residue accumulates on the flue
lining. When ignited, this creosote fuels an extremely
hot fire.
The chimney connector and chimney flue should be
inspected at least twice monthly during the heating
season to determine if creosote buildup has occurred.
If creosote has accumulated, it should be removed to
reduce the chance of a chimney fire.
In the event that creosote ignites in the flue, the
resulting fire is often accompanied by a roaring noise
and crackling sound as flakes of burning creosote break
loose. If you suspect you are having a chimney fire,
immediately close the air controls and make sure the
door is closed securely. Call the fire department and have
everyone leave the house.
Do not attempt to extinguish the fire. Opening the door
will only supply additional oxygen and intensify the
fire. When the fire in the flue has subsided, resist the
temptation to open the door to check on the fire. The fire
may have suffocated, but could re-ignite with a supply of
fresh air. After a chimney fire, do not use the stove until
the chimney connector and flue have been cleaned and
inspected to ensure no damage has been sustained.
See Section 6.6 of this manual regarding chimney
cleaning.
5.11 Ash Removal
Ashes will drop through the bottom grate into the inter-
nal ash pan during normal operation. Empty the ash pan
periodically, depending on how frequently the stove is used.
Avoid letting the ash accumulation to spill over the pan and
into the pan housing.
Always wear safety gloves when handling the ashes.
Ashes should only be placed in a metal container equipped
with a tight sealing lid.
The container should be placed on
a noncombustible floor or on the ground, well away from
all combustible materials, pending final disposal. If the
ashes are disposed of by burial in soil or otherwise locally
dispersed, they should be kept in the closed container until
all cinders have thoroughly cooled.
