• Excessive chimney draught.
The combustion air does not reach the fuel, but leaves the appliance via the
chimney. The fi re cools and the combustion quality decreases.
• Using too much wood.
This is a problem if your fi replace insert is too small. In that case, it becomes
overloaded and burns more wood than heat emitted. In this case too the fuel
cannot burn completely. More to the point, there is not enough air to mix with
the fl ames. This has an extra impact on the environment.
• Admitting too much air under the fuel.
(Combustion air supply slider is fully over to the “
+
” position.)
Combustion is raised to high intensity (like a blacksmith’s fi re). Combustion
really needs time. If combustion is too intense, there is insuffi cient time for
the fi re to radiate all the heat.
The chimney will become excessively hot and the same will be true of the
escaping smoke. This heat is thus lost.
