WARNING
When wood is burned slowly, it produces tar and
other organic vapors, which when combined with
expelled moisture form creosote. The creosote
vapors 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. ...A creosote
deposit just 1/8’’ (3 mm) thick is enough to cause
a chimney fire.
COAL:
Some coals contain large quantities of sulphur
(up to 7%). When coal is burned, sulphur and
coal ashes are deposited in the chimney flue. This
deposit combines with moisture to form a highly
corrosive acid (sulphuric acid). In order to protect
your chimney, we recommend that you:
1. Burn only low sulphur coals (less than 1%
sulphur).
2. Have your chimney cleaned within 48 hours
of shutting down your stove at the end of the
heating season. Be certain that all the soot is
removed. Wipe the chimney flue using a strong
solution of baking soda and water. This can
be done by wrapping a rag around a chimney
cleaning brush, dipping it into the baking
soda-water solution then passing it through the
chimney three of four times.
CREOSOTE FORMATION AND NEED FOR REMOVAL
Clearance
The clearances stated in this guide are minimum re-
quirements: if more space is available, use it. Min-
imum clearances mean leaving unobstructed air
space.
Inspection
Contact local building or fire officials about restric-
tions, installation inspections and permits that may
be required in your area.
Replacement Parts
If a component of your chimney system is damaged
it must be replaced by an identical one from
DuraVent.

WOOD AND COAL STOVES
If you are planning to install a wood stove, we rec-
ommend that you:
1. Choose a stove that bears the label of a test-
ing laboratory (such as ULC, CSA, WH, UL, or
ICBO).
2. Choose the right size stove. Do not buy one
larger than you need.
3. Connect only one appliance to a chimney.
4. Never overfire your stove. If any part of the
stove or stove pipe is glowing red, then you are
overfiring. Immediately close the stove’s damp-
ers until the system cools. The high temperature
caused by overfiring can permanently damage
the stove and stove pipe and may overheat
nearby combustible walls and furniture.
5. Install the stove and stove pipe as described in
the installation instructions accompanying the
stove. Be certain to maintain the required clear-
ances to combustible construction.
6. Keep your flue gases between 300°F and 500°F.
This will maximize efficiency while minimizing
condensation and creosote formation. Do not
fill your stove with wood and allow it to smolder
for 8 to 10 hours. This condition produces large
amounts of creosote in the chimney.
WARNING
In Case of Fire: If a flue fire occurs, close all appliance
draft openings, and call your Fire Department. Do not
use the chimney again, until it has been inspected for
possible damage.
