ECO 810
Adverse effects on the output are:
Ÿ
Burning the fi 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 fi re.
Ÿ
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.
Ÿ
Using too much wood. This is a problem if your fi re 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.
Ÿ Admitting too much air under the fuel (Operating handle for primary air/ridling
grill.).
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.
