3. Combustion air supply
The wood-burning stove may only be installed in rooms with a sufficient supply of combustion air. It is
guaranteed in rooms that have at least one door or window leading to the external environment that can be
opened or that are directly or indirectly interconnected with other rooms, forming a combustion air unit
with them. Such a unit only comprises rooms of one apartment or commercial unit.
THE WOOD-BURNING STOVE REQUIRES APPROX. 15 - 40 M³/H OF COMBUSTION AIR (see Table
1.1 Technical specifications and dimensions ).
In the case of new, insulated houses and mainly houses with
mechanical ventilation it is important to supply enough
combustion air. The wood-burning stove has a central connection
(from the bottom or from the back) used to supply enough air
directly to the combustion process. It means that you can provide
air via a connection pipe. The air supplied this way can be directly
controlled on the stove with a combustion air slider.
4. Operation
4.1 Stove controller
Lever on the right (P) Primary and secondary air is open.
Lever in the middle (S) Primary air closed
Secondary air open
Lever on the left (0) Primary and secondary air closed
1) Air control slider (combustion air slider)
2) Grill draw-bar
Primary air
is used to control combustion air from the bottom that flows through the ashpan and the grate into
the stove. Therefore, do not let the ashpan get completely filled with ashes as the ashes might prevent the supply
of combustion air.
Secondary air controls the air quantity that is necessary to burn mainly the flammable products that are generated
in the combustion chamber during burning of wood. A certain part of secondary air that flows from the top to the
door minimizes soiling of the glass (air cleaning of the door).
As soon as the stove is heated up after the firing, close the primary air supply. Then, you can control the
combustion intensity with the secondary air only.
The
grate control is used to open and close the grate.
4.2 Door
Automatic closing of the door is ensured with the use of a spring. The spring must never put out of operation.
Locking
must be done manually.
4.3 Throttle flap
It is used to control the draught of the flue. During the firing and the
heating-up stage the throttle flap should be open (+). During residual
glowing, when no flames are seen any longer, it can be closed. This
way you can achieve longer presence of hot gases in the wood-
burning stove.
The central air supply
connection for Ø 125 mm.
The temperature of the
