5. Troubleshooting

5.1.

Poor draught

Check the length of the chimney and that it complies with
national laws and regulations. Make sure that there is not
anything preventing the smoke gasses from escaping:
branches, trees, etc.
Upon suspicion of excessive/poor draught in the chimney,
seek professional help for measurement and adjustment.
5.2.

The fire extinguishes after a while

•
Make sure that the firewood is sufficiently dry.
•
Find out whether there is negative pressure in the house,
close mechanical fans and open a window close to the
fireplace.
•
Check that the air vent is open.
•
Check that the flue outlet is not clogged by soot.
5.3.

Unusual amount of soot on glass

Some soot will always stick to the glass, but the quantity
depends on:
•
Moisture in the fuel.
•
The local draught conditions.
•
Air vent opening.
Most of the soot will normally burn off when the air vent is
opened all the way and a fire is burning briskly in the fireplace.
