Solution
Glass becomes
sooted heavily,
rapidly and
unevenly.
You did not use the correct combustion materials.
2.
Use natural, bulky bits of timber compliant with BImSchV §3 (German legislation).
The ambient temperature is above about 15°C. The weather conditions are unfavorable
(e.g. fog). These weather conditions occur most frequently in spring and fall.
4.1
Fill the fireplace with a small amount of fuel and light it with the damper fully open
(max. air flow).
There is a temperature inversion. That means that the upper layers of the atmosphere
are warmer than the lower layers.
4.1
Fill the fireplace with a small amount of fuel and light it with the damper fully open
(max. air flow).
The combustion air controller is not fully opened.
3.2.1
Move the air actuating lever into its far right-hand position.
The external combustion air line is not free.
4.3
Clean the combustion air line.
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!)
3.2.1
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.
The seating of a gasket / door seal is not perfect.
-
Check all seals, e.g. open the fire door and press the seal fully into the door profile.
The wood is not dry enough.
2.
Measure the residual humidity in the wood used with a humidity detector. The recom-
mended residual humidity is 20% or less.
Not enough wood has been added. (an insufficient amount of wood can result in temper-
atures in the stove not being high enough).
2.1.3
The proper amount of wood per hour can be found in the technical data.
The chimney draught is too strong / too weak.
-
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.
Fire is difficult to
ignite
You did not use the correct combustion materials.
2.
Use natural, bulky bits of timber compliant with BImSchV §3 (German legislation).
The wood is not dry enough.
2.
Measure the residual humidity in the wood used with a humidity detector. The recom-
mended residual humidity is 20% or less.
The wood too thick.
2.
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-
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.
A sufficient air supply is not assured.
3.
For heating or for adding more firewood, move the actuating lever fully to the right.
The ambient temperature is above about 15°C. The weather conditions are unfavorable
(e.g. fog). This is referred to as an intervening period.
4.1

3.2.1

The external combustion air line is not free.
4.3
Clean the combustion air line.
The chimney is not free.
-
Inform the chimney sweep.
There is not enough vacuum in the chimney.
-
Light a small fire in the fireplace, following advice from your fireplace installer or
chimney sweep.
