First Time of Use:
The paint will harden the first time the cassette is used. This will result in a burned smell, which, however,
disappears again when the room is thoroughly aired.
LIGHTING AND STOKING
Primary air for the lightning:
The handle for the primary air (see sketch, no. 7) is underneath the door at the left side of the cassette. By pulling
out the handle the primary air is opened. The primary air should be fully opened in approximately 2 minutes
during lightning and stoking.
Lightning:
For lighting use pieces of crumbled paper (newspaper) and/or firelighters, and about two kgs wood (small pieces)
on top of the paper. Do never use oil, gas or other flammable liquids!
The combustion air (see sketch, no. 6) should be fully opened. Paper and/or firelighters are lighted and the door
remains slightly open. When the fire has caught on well, after about 10-15 minutes, the cassette is ready for the
first portion of wood, and the combustion air and primary air are adjusted according to the following diagrams.
Depending on the chimney draught the position of the air valves can change.

Stoking:
Use the amount of fuel previously specified and ensure that the wood has the prescribed size. Do not pack the
wood too closely - this is important in order to obtain an optimal airflow in the combustion material. Close the
door after approx. 2 min. To avoid overheating, close the ash pan (SCAN DSA 3) as soon as the fire has caught
on well. The ash pan must only be opened during lightning and stoking.
Please make sure that the right amount of fuel is used (according to the previous table). Otherwise the
temperature in the chimney can be too high and the efficiency too low and a damage of the chimney can occur.
Stoking During Spring Time and Autumn:
At outdoor temperatures of more than 15°C, the cassette may be under fired, and a so-called "cold" combustion
will build-up. The result will be an increasing formation of soot in the smoke ducts of the cassette, the chimney
connector, and in the chimney. To avoid the soot build-up, we recommend that you clean the smoke ducts more
frequently and increase the supply of combustion air. Small pieces of wood should be used, and fuel should be
added more frequently.
Chimney Draught:
The chimney draught depends on the weather conditions. In stormy weather, you may reduce the chimney
draught by closing the damper in the smoke pipe (if a damper has been installed). If the chimney draught is
strong, the combustion air supply must be reduced additionally.
Room Ventilation:
During the combustion, oxygen taken from the room air is used. In order to get sufficient air for the combustion,
leave the windows half open in well-insulated rooms or have a fresh-air intake installed.
Cleaning:
Be careful when you empty the cassette for ashes. There may be glows left as long as 24 hours after the cassette
was last used. The ash may, when it is cold, be placed in a garbage bag.
