After adding firewood, the combustion air must once again be opened fully
in order to burn the additional wood rapidly. This causes high combustion
temperatures to be reached again almost immediately, the key to complete and
environment-friendly combustion.
Depending on the type and quantity of wood, remaining embers and chimney
draught, this reheating phase may take about 5 minutes, until the combustion
air, in a way similar to that described in Point 8, can be restricted.
End of the combustion process!
3.3 FIRING/ADDING WOOD
• Depending on weather condition, move the actuating lever more of less
into centre position or slightly above it (closing the supply of air). This
always depends on experience and on prevailing conditions on location.
• Do not open the doors forcefully or gases may enter your living room
through a suddenly produced negative pressure. At first, open the door
slowly and only a crack.
• Putting fresh firewood onto hot embers prevents the possible release of
smoke when the door is opened.
• Typical intervals for adding firewood are 30 to 60 minutes approx., which
ensures that the fireplace insert can be operated continuously.
• When adding fresh firewood, completely cover the hot embers.
• Depending on how much firewood you add, you may move the actuating
lever completely to the right for a few minutes until that fresh firewood is
burning brightly.
• After adding fresh firewood, never choke off the flow of combustion air.
Risk of explosion!
• Never repeatedly put more than the recommended amount of wood onto
the fire.
• This also applies whenever the fireplace system is not operational
• Never close the actuating lever completely during the burn-up process
(risk of explosion).
4. TECHNICAL INFORMATION
4.1 HEATING DURING THE TRANSITION PERIOD
The basic requirement for correct fireplace system function is the draught
produced by your chimney (pressure head). This is dependent on the outside
temperature and therefore, to a large extent, on the season. Higher ambient
temperatures during the shoulder seasons (spring and fall) can lead to weaker
draughts and consequently, poorer combustion or more smoke production.
What can you do to help prevent this?
• Empty the ash can and grate before lighting a fire. Place grate with
embossed engraving facing downwards.
• If the chimney draught is less than this, a larger ‘initial burn’ should be
12. If no more firewood is to be added, the actu-
ating lever can be closed completely using the
‘cold hand’ as soon as there are only a few
remaining hot embers.
The end of the burning process is achieved when
the wood has burned completely, and no smold-
ering or incomplete combustion can occur. Now
the actuating lever can be closed (left position).
11. Provided that there are sufficient hot embers,
you can continue adding fresh firewood.
