CREOSOTE - FORMATION AND NEED
FOR REMOVAL
Wood stoves can quickly create large deposits of
creosote in the chimney. Some wood stoves can
create enough creosote in two weeks to cause a
chimney fire.
When wood is burned slowly, it produces tar and other
organic vapours, which combine with expelled mois-
ture to form creosote. The creosote vapours 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.
When using a wood stove, we recommend that you::
1. Initially, inspect the chimney system weekly. You
will learn how often it will be necessary to clean
your chimney.
2. The chimney should be inspected at least once every
2 months during the heating season to determine
if a creosote or soot build-up has occurred: if a
significant layer of creosote has accumulated (3
mm or 1/8''), it should be removed to reduce the
risk of chimney fire.
3. Have your chimney cleaned by a qualified chimney
sweep. If you want to clean your chimney yourself:
clean your chimney using plastic or stainless steel
brushes. Do not use a brush that will scratch the
stainless steel interior of your chimney.
4. Do not expect chemical chimney cleaners to keep
your chimney clean. Their use does not negate the
necessity of periodically inspecting and cleaning
your chimney.
In Case of Fire: If a flue fire occurs, close all appliance
dampers and source of combustion air, and call your
Fire Department. Do not use the chimney again, until it
has been inspected for possible damage.

CAP REMOVAL FOR MAINTENANCE
To remove cap, unscrew the collar screw to un-
tighten the collar.
Pull on the cap to remove it from the chimney.
To put the cap back in place, slide it over the
chimney and then tighten the collar using the col-
lar screw.
