Banned fuel types 

It is not allowed to stoke a fire with the following: printed matter, plywood, plastic, rubber, fluid fuels, 
and rubbish such as milk cartons, lacquered wood or impregnated wood and fossil fuels. The reason that 
you should not apply any of the above is that during combustion they develop substances that are health 
hazardous and harmful to the environment. These substances could also damage your wood burning stove 
and chimney, rendering the product warranty void.

Storage of wood

A water content of a maximum of 20% is achieved by storing the wood for a minimum of one year, 
preferably two years, outdoors under a lean-to. Wood stored indoors has a tendency to become too 
dry and combust too quickly. However, it might be advantageous to store fuel for lighting a fire indoors 
for a few days prior to use.

Recommended dimensions 

The dimensions of the fuel are important to good combustion. The dimensions should be as follows: 

Fuel type

Length in cm

Diameter in cm

Wood for kindling a fire (finely chopped)

25-30

2-5

Chopped wood

25-30

Special lighting guide for wood-burning stoves with soapstone cladding

Soapstone is a natural product that must be allowed to adapt to fluctuations in temperature. We recom-
mend following the procedure below:

1. First stoking

Turn the regulator (drawing E, 1) clockwise to maximum. Place two pieces of wood (5-8 cm in diameter) 
horizontally in the bottom of the combustion compartment (corresponding to 1-2 kg). Place 5-8 pieces 
of kindling randomly on top. Place two firelighters between the top layer of kindling. Light up the fire-
lighters and close the stove door.  If condensation forms on the glass, keep the door ajar for a little while 
and close again. When the fire has gone out, open the door and leave it open while the stove cools to 
room temperature.

2. Second stoking

Turn the regulator (drawing E, 1) clockwise to maximum. Place two pieces of wood (5-8 cm in diameter) 
horizontally in the bottom of the combustion compartment (corresponding to 1-2 kg). Place 5-8 pieces 
of kindling randomly on top. Place two firelighters between the top layer of kindling. Light up the fire-
lighters and close the stove door. If condensation forms on the glass, keep the door ajar for a little while 
and close again. When no more yellow flames are visible and a suitable layer of embers has built up, the 
stove can be stoked again. There is a suitable layer of embers when the bottom of the stove is covered 
completely. Half fill the combustion chamber with dry wood with a diameter of about 7-9 cm. When all 
of the wood has caught fire, turn the regulator (1) to middle position. Allow the fire to burn and let the 
stove cool to room temperature before stoking again.

3. Third  stoking

Repeat the procedure for the second stoking, but put in more wood this time. Allow the fire to burn and 
let the stove cool to room temperature after the fire has gone out.

Restoking:

Follow the general instructions, see the sections “Lighting the stove” and “Stoking”.

Lighting the stove (drawing E)

A successful combustion process requires that the wood is lit in the right way. A cold stove and a cold 
chimney challenge the combustion process. It is important to achieve a high flue gas temperature quickly.
Turn the regulator (1) clockwise to maximum. Place two pieces of wood (5-8 cm in diameter) horizontally 
in the bottom of the combustion compartment (corresponding to 1-2 kg). Place 5-8 pieces of kindling
