During the first few times the stove is used, it is possible that it can produce a slight smell 

while the paint is curing. This will disappear after a short while. If the smell appears, open 

the windows of the room for ventilation. 

ATTENTION 

THE ASHPAN MUST BE TIGHTLY CLOSED FOR PROPER REGULATION OF THE 

PRIMARY AND SECONDARY AIR. 

If ash is allowed to build up behind the ashpan then it can prevent the ashpan sealing 

properly. 

6.2. Suitable materials for lighting 

The stove should be used for the combustion of natural wood and wood briquettes. 

Some of the best wood for the stove is beech and birch. These types of wood have the 

highest burn temperature, and they burn the cleanest, as long as they have been stored in 

a dry place for a sufficient length of time. 

If the glass window blackens excessively during burning it is usually an indication that the 

moisture content of the firewood is too high. 

Do not use any of the following: 

 

Damp wood or treated wood 

 

Cardboard 

 

Bark or plywood 

 

Plastic or other waste 

Fresh wood should be cut up and stored 12 to 18 months in open storage, but protected 

from rain. According to the manual, any wood used should have a maximum humidity of 

20%. 

6.3 Emptying the ashpan 

It is recommended to clean out the ash every day. 

Be careful that too much ash is not accumulated otherwise there is the danger that, if the 

ash reaches up to the grate, it will not cool sufficiently and may get damaged. 

Before emptying the ashpan, check if there are any embers left in the ashtray. 

Even though the ash is cold from the outside, it is possible that there are embers within the 

ash which can lead to a fire in the waste bin.
