ECO 40 / 52 / 55
Adverse effects on the output are:
• Burning the • re with the door open.
A warm chimney works in the same way as an extractor. When the door is
open, the chimney draws in much more air than is necessary for combustion.
This relatively cool air cools down the • re.
• Excessive chimney draught.
The combustion air does not reach the fuel, but leaves the appliance via the
chimney. The • re cools and the combustion quality decreases.
• Using too much wood.
This is a problem if your stove 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 • 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 • re). Combustion
really needs time. If combustion is too intense, there is insuf• cient time for
the stove 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.
