The wood must be dry (max. 18% water contents) before it is stored indoors. It is recommended that
kindling wood is stored indoors for a couple of 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) 30-45 2-5
Chopped wood 30-45 7-9
Special fire lighting guide for stoves with soapstone or sandstone cladding
Soapstone and sandstone are natural products which need to adjust to temperature changes. We
recommend following the procedure below:
1. The first stoking
Place two pieces of wood (5-8 cm in diameter) horizontally in the bottom of the combustion compart-
ment (corresponding to 1-1,5 kg). Place 6-10 pieces of kindling randomly on top. Place four firelighters
between the top layer of kindling. Press the remote control twice to activate the symbol of lighting up.
Light up the fire-lighters and close the stove door. Adjust the temperature selection mechanism on the
remote control to level one. Let the fire burn out and do not restoke even if there is a restoking alarm.
When the fire has died out completely, the door must be opened and stay open while the stove cools
down to room temperature.
2. The second stoking
Place two pieces of wood (5-8 cm in diameter) horizontally in the bottom of the combustion compart-
ment (corresponding to 1-1,5 kg). Place 6-10 pieces of kindling randomly on top. Place four firelighters
between the top layer of kindling. Press the remote control twice to activate the symbol of lighting up.
Light up the fire-lighters and close the stove door. Adjust the temperature selection mechanism on the
remote control to level two. When there is a restoking alarm, you should restoke. Place 2 pieces of new
firewood (up to 1.2 kg each) with a diameter of approx. 7-9 cm in the combustion chamber. Let the fire
burn and let the stove cool down to room temperature before the next lighting.
3. The third stoking
Repeat the second stoking, but use more wood this time and adjust the temperature selection on the
remote control to level three. Let the fire burn and allow the stove to cool down after the fire has died out.
Lighting Up
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.
Only at temperatures around 350° C will environmentally friendly combustion take place.
Place two pieces of wood (5-8 cm in diameter) horizontally in the bottom of the
combustion compartment (corresponding to 1-1.5 kg). Place 6-10 pieces of kindling
randomly on top. Place 4 fire-lighters in between the top layers of kindling. Press
the remote control twice to activate the symbol of lighting up. Light up the fire-
lighters and close the stove door. Adjust the temperature selection mechanism
on the remote control to the desired heat level.
If the desired flue gas temperature of 350° C has not been achieved within 15 minutes, the remote control
will activate a re-stoking alarm even if there still might be wood and flames in the combustion compart-
ment. The re-stoking alarm can seem misplaced, but it is activated because the temperature climbs too
slowly. Re-stoking with small pieces of kindling wood can often result in a faster increase in temperature.

closes all three air dampers when the stove is in standby mode. This prevents
hot air from the room to enter the chimney (heat loss). This might on the other hand result in a very
cold chimney when the stove is lit. In certain cases it is necessary to assist the draught in the chimney by
