The doors or the air register input were closed too quickly. The contribution of air is essential
to the maintenance of combustion.
If the room is too airtight, or the house has a negative pressure and does not have any
external air intake, the contribution of air to the fireplace will be more difficult than usual.
Temporarily open a window near the fireplace to increase it.
Any ventilator (cook top exhaust fan, bathroom ventilator, central vacuum cleaner or dryer)
inhales air toward outside. This could create a negative pressure in the house. Turn it off or
open a window near the fireplace to solve this problem.
b) Wet wood
Wet wood releases more smoke while burning than seasoned wood. Wetter the wood is,
less heat it releases and more creosote it produces. If the wood burnt is very wet, inspect
the chimney each month that the fireplace is in use.
c) Dirty or blocked chimney
Make sure that the chimney is reasonably clean and free of any obstruction.
d) Chimney not long enough
Check if the chimney is sufficiently high: minimum of 914 mm (
3’) above its junction with the
roof (See page 23). If not, add additional lengths of duct, which will increase the pulling of
the chimney and will reduce tendency of the return of smoke.
The chimneys joined with an external wall (See page 19 right drawing) without facing often
present problems. Open a window near the fireplace.
Always remove the surplus of ashes before lighting a fire. Maintain a thickness of 24 mm
(
1’’) of ashes to optimize the combustion and maximize the duration of fire.
2.3 FUNCTIONNING OF THE FIREPLACE
2.3.1 Creosote
When wood burns slowly, it produces tar and other organic vapours which, when associated with
moisture, forms the creosote. The creosote vapour condenses in a chimney-flue relatively cooled by
a slow fire. The result is an accumulation of creosote inside the pipe.
When burning, the creosote forms an extremely blazing hot fire.
It is preferable to make small brisk fires rather than large smouldering fires. This will enable you to
keep the chimney and panes clean.
2.3.2 Chimney-sweeping
The chimney should be inspected periodically during heating season to check for creosote
accumulation. If there is an accumulation of creosote (3 mm or more), the chimney must be cleaned
to prevent a risk of chimney fire.
It is necessary to sweep the chimney after an accumulation of 3 mm of creosote.
2.3.3 Smoke detector
Do not install your smoke detector to close to your fireplace because it will start when opening the
door for loading.
2.3.4 Firewood
Avoid using green wood to slow down combustion. This causes the formation of excessive soot and
creosote deposit in the chimney. It may cause a chimney fire.
