Room ventilation

There must not be an extractor fan fitted in the same room as the stove as this can 

cause the stove to emit smoke and fumes into the room. 

The stove requires a permanent and adequate air supply in order for it to operate safely 

and efficiently. 

In accordance with current Building Regulations the installer may have fitted a perma-

nent air supply vent into the room in which the stove is installed to provide combustion 

air. This air vent should not under any circumstances be shut off or sealed. 

Drying and storage

Drying wood takes time. Proper air drying takes approx. 2 years. 

Here are some tips:

•  Store the wood sawn, split and stacked in an airy, sunny place, which is protected 

against rain (the south side of the house is particularly suitable).

•  Store the firewood stacks at a hand’s breadth apart, as this ensures that the air 

flowing through takes the moisture with it. 

•  Avoid covering the firewood stacks with plastic, as this prevents the moisture from 

escaping. 

•  It is a good idea to bring the firewood into the house 2-3 days before you need it.

Regulating the combustion air

The stoves are equipped with a one-handed operating lever for regulating the damper. 

The stove-specific regulating mechanisms can be seen on the diagrams (front of manu-

al).

The primary air is added to the primary combustion zone at the bottom of the burning 

chamber, i.e. the bed of glowing embers. This cold air is only used in the lighting stage.

Secondary air is the air, added to the gas combustion zone, meaning air, which con-

tributes to the combustion of the pyrolysis gasses (preheated air, used for cleaning the 

glass and combustion). This air is sucked through the damper below the burning cham-

ber and is pre-heated through the side channels and then emitted as hot scavenging air 

onto the glass. The hot air rinses the glass and keeps it soot-free.

Tertiary air at the back of the burning chamber at the top (row of holes) ensures the 

combustion of the final gas residues and particles before leaving through the chimney.

The pilot nozzles are placed at the bottom and front of the combustion chamber. They 

ensure that the bed of glowing embers is fed with air and therefore holds a high tem-

perature. It provides a quick start when refuelling and reduces the risk of fire going out.

By setting the interval between position 1 and 2, the energy content in the firewood is 

used optimally, as there is oxygen for combustion and for the burning of the pyrolysis 

gasses. When the flames are a clear yellow the damper has been set correctly. Finding 

the correct position comes with time after you have used for stove for a while.

It is not recommended that you turn it down completely. A mistake commonly made 

is shutting the damper too early because it feels too hot. This results in dark smoke 

emanating from the chimney and in the calorific value of the firewood not being used 

to its fullest.
