MAINTAINING YOUR BIS TRADITION
3.3.1 Creosote
When wood is burned slowly without a flame, it produces tar and other organic vapours
which combine with expelled moisture to form a black deposit called creosote which
accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire. If
the creosote accumulation is large, a creosote fire in the chimney can damage the chimney and
overheat the surrounding wood framing. Creosote formation in a chimney can be minimized
by making sure there is always visible flame burning, avoid smouldering fires and by proper
refuelling techniques.
3.3.2 Chimney Maintenance
Regular chimney inspection and maintenance combined with proper operation will prevent
chimney fires. Keep your chimney clean. Do not allow more than 1/16" creosote build up in
your chimney. The amount of creosote will depend on variables such as frequency of use
and type of fire. We recommend that you:
A.
Initially inspect the chimney system weekly. From this, you will learn how often it will
be necessary to clean your chimney.
B.
Have your chimney cleaned by a qualified chimney sweep. If you wish to clean it
yourself, we recommend using a stiff plastic or non-metallic brush. If a metal brush is
used, its size should be slightly smaller than the flue to avoid damaging the chimney. Do
not use a brush that will scratch the stainless steel interior of the chimney.
C.
Do not expect chemical cleaners to keep your chimney clean. The rain cap can be
removed for inspection and/or cleaning of the chimney.
3.3.3 Dealing With a Chimney Fire
Regular chimney maintenance and inspection can prevent chimney fires. If you have a
chimney fire, follow these steps:
1.
IMPORTANT: Close the fireplace door and the combustion air controls; this will stifle
the fire.
2.
Alert your family of the possible danger.
3.
If you require assistance, alert your fire department.
4.
If possible, use a dry chemical fire extinguisher, baking soda or sand to control the fire.
Do not use water as it may cause a dangerous steam explosion.
5.
Ensure that sparks and hot embers coming out of the chimney are not igniting the roof.
6.
Do not use the fireplace again until your chimney and fireplace have been inspected by a
qualified chimney sweep or a fire department inspector.
