There is a temperature inversion. That means that the upper layers of the atmosphere
are warmer than the lower layers.
The combustion air controller is not fully opened.
The external combustion air line is not free.
Combustion air is too heavily restricted. This means that soot accumulates quickly,
within just half an hour. (it is normal for the fireplace unit to become progressively dirtier
from operation. When driving, a car window becomes dirty, too!)
The seating of a gasket / door seal is not perfect.
The wood is not dry enough.
Not enough wood has been added. (an insufficient amount of wood can result in temper-
atures in the stove not being high enough).
The chimney draught is too strong / too weak.

The wood too thick.
A sufficient air supply is not assured.
The ambient temperature is above about 15°C. The weather conditions are unfavorable
(e.g. fog). This is referred to as an intervening period.
There is a temperature inversion. That means that the upper layers of the atmosphere

The chimney is not free.
There is not enough vacuum in the chimney.

Solution
2.
Use natural, bulky bits of timber compliant with BImSchV §3 (German legislation).
Fill the fireplace with a small amount of fuel and light it with the damper fully open

(max. air flow).
3.2.1
Move the air actuating lever into its far right-hand position.
4.3
Clean the combustion air line.
Check the position of the air lever and, if necessary, open up the combustion air flow rate

fully to bring the fireplace unit up to operating temperature.
-
Check all seals, e.g. open the fire door and press the seal fully into the door profile.
Measure the residual humidity in the wood used with a humidity detector. The recom-
2.
mended residual humidity is 20% or less.
2.1.3
The proper amount of wood per hour can be found in the technical data.
Observe the situation. The draught characteristics can be affected by the prevailing
-
weather pattern. If the glass continues to soot up badly, inform your chimney sweep.

Use small-sized timber to light the fire. For firewood, use only split wood that is not
thicker than about 8 cm at its thickest point. The optimum length of firewood is approx-
2.
imately 20 - 25 cm. In the case of prolonged heating, do not add too much wood.
Instead, it is better to add smaller quantities of wood.
3.
For heating or for adding more firewood, move the actuating lever fully to the right.
Fill the fireplace with a small amount of fuel and light it with the damper fully open
