5. Leave the air adjustment lever in the fully open position (far right) for about 2
to 5 minutes. Wait for all the new wood to catch light before altering the air
adjustment lever position again.
6. Then move the lever to the middle
position B.
The end of the burning process is achieved
when the wood has burned completely, and
no smoldering or incomplete combustion
can occur. Now the lever can be closed.
Always leave the air adjustment lever in the
closed position C when the stove is not in
use (see Fig. 23).
4.3.2 HOURLY WOOD CONSUMPTION RATE
In order to avoid damage due to over-heating (discolouration of the steel,
deformation, etc.) and to guarantee optimum performance over the lifetime
of the appliance, ensure that the stove is fuelled in the proper manner.
To prevent any risk of over-heating, make sure that the maximum heating
capacity is never exceeded.
The proper amount of wood feed per hour can be found in
„2.2 Technical data“ on page 6. The individual wood logs should be no
more than approx. 25 cm in circumference!
Please note: Increasing the wood feed beyond this amount may result in
overheating and damage to the stove. Wood pellets (briquettes) have a
higher heat output than hardwood. Hourly consumption when using pellets
should therefore be at least 20% lower than when burning logs.
The warranty will be voided in cases of damage due to overheating (exces-
sive hourly wood consumption).
4.4 CONTROLLING HEAT OUTPUT
Heat output is controlled by regulating the amount of fuel added. Do not try
to slow down combustion excessively by reducing the flow of inlet air. When
heating with wood, this causes incomplete combustion and therefore wastes
fuel and causes unnecessary levels of environmental pollution because
wood releases gases even if no flames are produced. This also increases
the soot deposits on the viewing panes! What is more, there is the risk of
deflagration (explosive ignition of the flue gases).
Ensure that the firebox door is always firmly closed to prevent combustion
being accelerated by the uncontrolled inflow of air. Your stove’s output also
depends on the chimney draught. This draught can be adversely affected
by the cross section of the chimney, or by environmental factors such as
strong winds etc.
4.5 ROOM HEATING CAPACITY / INDOOR CLIMATE
The room heating capability used to be quoted in accordance with the DIN
18893 standard (most recent edition being August 1987) so is no longer a
meaningful indicator for modern houses constructed after 1990. However,
the old room heating capacity value may still be of interest as a comparative
value or for use in the case of older structures pre-dating the 1977 thermal
insulation standard.
