Solution
Fire is difficult to
ignite
The wood too thick.
5.
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 approximately 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.
4.2.
For lighting the fire or adding more firewood, move the actuating lever fully to the right.
The ambient temperature is above
about 15°C. The weather conditions
are unfavourable (e.g. fog). This is
referred to as an intervening period.
4.6
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.
4.6
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.
4.2
Move the air actuating lever into its far right-hand position.
The external combustion air line is
not free.
2.4.3
Clean the combustion air line.
The chimney is not unobstructed.
-
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.
Smoke escapes
when adding
wood
Air-extracting equipment is switched
on, e.g. kitchen extractor fan.
-
Ensure that all air-extracting equipment is switched off.
Wood added prematurely, on top of
unburned wood.
4.3.1
Do not add fresh firewood until there is a bed of hot embers in the combustion chamber.
The chimney is not unobstructed.
-
Inform the chimney sweep.
Your fireplace has not already reached
its operating temperature.
-
Burn down remaining wood until it forms a bed of hot embers, then add smaller pieces of firewood.
The door has been opened too wide.
4.3.1
Open the door slowly and carefully.
