What is wrong with a smoking chimney?
A seriously smoking chimney means that combustion is less than optimum.
There may be a number of reasons for this. If the fi re has only just caught on,
or has recently been topped up, some smoke is normal. By opening the door
for a short period, the wood will catch fi re quicker and the smoky period will be
shorter.
If you leave the fi re door open, and especially if you burn damp wood, the result
will be a lot of smoke. In both cases, the combustion temperature is too low. This
leaves numerous dangerous compounds intact, which means more deposits in
your chimney and more waste into the environment.
What should I do if the wood does not catch fi re?
This probably means that the wood is damp. Remove the wood and replace it
with dry wood. If necessary, make a fi re with wood briquettes. They are always
dry (they have a moisture content of <10%).
The wood burns up too quickly. What should I do?
Ensure that air cannot get in underneath the fuel. Move the combustion air
supply slider towards the “
- ” position. (The primary air supply is now closed.)
Under these conditions, the layer of ash should no longer burn bright orange/
white but red.
If there is a draught (due to strong wind), air intended as secondary air for above
the fuel may enter through the openings above the door and fl ow straight down
beneath the wood. Also slide the combustion air supply slider tighter shut.
There may be too much of a draught in your chimney, particularly if it is very high
(in excess of 8 m). Ask your supplier to fi t a check valve or damper. This may not
be possible in all cases.
Can I leave my fi re unattended?
Only do this when the appliance is burning quietly, with just a little wood, with
a closed door and with the combustion air supply slider in the centre position
between “
+
” and “
-
”. In this position, the primary air supply beneath the grate
is closed and the secondary/tertiary air supply is open. Secondary air is supplied
through the small holes in the rear panel of the combustion chamber. Tertiary air
is supplied through the opening behind the glass at the top of the combustion
chamber.
Do not leave children unattended while the fi re is burning.
