Operating instructions
Operation
Once the operating temperature has been reached, the first burnup should be
completed without reducing the combustion air. Once almost all the wood has been
burnt and there is a firebed with subtle flames, it is time to add more fuel. Larger
sized pieces of firewood can now be chosen.
The amount of wood added depends on the heating requirements. The air valve
should remain fully open until the wood which has been added is properly ignited. To
prevent the basic stove from overheating, a surface temperature of max. 85°C
should be aimed for.
The combustion air can now be reduced for further operation and the speed of
combustion thus slowed down. In principle, however, the thermal output is controlled
by the amount of fuel added and the operating time. The combustion air may only be
reduced to the extent that clean combustion is ensured. If dark threads of smoke
form on the tips of the flames, the combustion air was reduced too much.
Maintaining the glowing embers
After the flames have gone out, an energy-loaded firebed remains in the combustion
chamber. It can now be decided whether the fire should be revived with thin firewood
and an open combustion air supply or if the combustion air should be reduced again
at the end of the heating phase to maintain the glowing embers for longer. The air
valve is only closed completely if the stove is heated up and the firebed has gone
out.
Ash
Wood logs and wood briquettes produce only a small amount of combustion residue.
It will therefore be necessary to remove this ash from time to time.
This should be done when the bed of ashes is more than 5 cm high. It is staggering
how long embers can remain hot in seemingly cold ash. That is why ash should
never be thrown directly from the stove in the waste bin. It is recommended to store
ash temporarily in a metal bucket with lid. Ash is also suitable for composting.
