Possible causes of and remedies for
malfunctions for any type of stove
A whole lot of soot gets left on the glass
A slight soot coating on the glass pane is
unavoidable and ncreases a little with each firing.
In principle, soot on the glass has three
different causes:
-
The wood is too moist. This results in unclean
combustion with high smoke formation.
-
The ember bed has a temperature which is
too low. This results in high smoke formation
when adding wood and poor draught in the
smoke pipe.
-
Wrong handling, e.g. the primary air valves
are not sufficiently opened in the ignition
phase.
Test the moisture content of the wood. Ensure
that you maintain a sufficient ember and refer to
the heating manual if need be.
Temporary smoke odour near the chimney
stove
This can occur due to weather-related pressure in
the chimney and when it typically occurs with a
certain wind direction. If this occurs frequently,
speak with your chimney constructors about how
to remedy this effect.
Operation: Please ensure that you never open
the door in a jerking manner. The resulting under-
pressure can draw smoke into the installation
room. Loose lock first, wait until the fire adjusts to
the new air intake situation (2 – 3 seconds) and
open door slowly.
Discolouration of painted parts
A discolouration of painted parts is very rare and
is attributable to exceedingly high temperature in
the stove.
The reason for the excessive temperature can be
a continuous exceeding of the permissible
maximum quantity of wood or the use of
unsuitable fuels (e.g. pallet residuals, card-board,
large quantities of thin waste wood etc.).
Chimney fire
Causes: A chimney fire can occur when using the
wrong com-bustion material – e.g. wood moisture
too high – or improper operation of the stove.
Here excess tar and water vapours (as a kind of
greasy soot) and begin to cover the walls of the
inner chimney. If the saturation point of the
condensate is reached, an ignition of the
chimney with major flame and temperature
development may occur.
This is how to take effective precautions:
–
Use dry, well stored firewood.
–
Supply enough oxygen during the combustion
process.
–
Regularly service and clean the chimney.
–
Take care of the correct dimension of the
chimney.
–
Do not add to much firewood in order to
prevent a smouldering fire.
–
Please note the operating manual of the
stove.
What to do in an emergency
–
Contact the fire department – Emergency call!
–
Firmly close the doors and combustion air
supply of the firing installation.
–
Move all combustible items away from the
stove.
–
Keep/make free access to chimney cleaning
locks.
–
Notify the chimney cleaner.
–
Have a fire extinguisher ready.
Important! Never attempt to extinguish a
chimney fire with water!
Due to the evaporating water, this can result in a
'blasting effect' and the chimney can be seriously
damaged.
General malfunction
If problems occur which you cannot remedy
yourself, let the fire burn down and cool down the
stove.
Before recommissioning, please contact your
specialised dealer or professional chimney sweep
or contact Bullerjan GmbH directly.
