Storage of wood

A moisture content of 12-18% is achieved by storing recently felled wood outdoors under a lean-to 
for at least one year, preferably 2 years. 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.

We recommend that you buy a moisture meter to continuously check that the wood has the correct 
moisture content before it is used for firing. Split the wood and measure the moisture content of the 
split surfaces.

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)

Special fire lighting guide for stoves with soapstone or natural stone cladding

Stones are natural products which need to adjust to temperature changes. We recommend following 
the procedure below:

1. First stoking (drawing F)

Push the air control lever (1) all the way to the right push the shaking grate lever (2) all the way in. Place 
2 pieces of wood (5-8 cm in diameter) horizontally in the bottom of the combustion compartment (cor-
responding to 1-2 kg). Place 5-8 pieces of kindling randomly on top. Place 2 firelighters between the top 
layer of kindling. Light up the firelighters 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

Push the air control lever (1) all the way to the right push the shaking grate lever (2) all the way in. Place 
2 pieces of wood (5-8 cm in diameter) horizontally in the bottom of the combustion compartment (cor-
responding to 1-2 kg). Place 5-8 pieces of kindling randomly on top. Place 2 firelighters between the top 
layer of kindling. Light up the firelighters 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,  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 F)

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.
Push the air control lever (1) all the way to the right push the shaking grate lever (2) all the way in. Place 
2 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 2 firelighters between the 
top layer of kindling. Light up the fire-lighters and close the stove door.  If condensation forms on the
