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 controller 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.
According to 15a B-VG since 01.01.2015 only nominal load operation has been
permitted in Austria!
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.
At the end of the heating phase, the combustion air is reduced again to keep the
embers glowing for longer. The air controller 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.
