6. USE
6.1. VENTILATION
Air is a vital component of the combustion process. Ensure that there is a
suffi cient supply of fresh air. For each kilo of wood that you put on the fi re (door
closed), 10 - 15 m
3
of extra air is needed. That means 50 m
3
per hour! As you
can see, a plentiful supply of air is essential. Fresh air supply opening: minimal
50
cm 2 (= Ø80 mm).
6.2. GETTING THE FIRE GOING (Figure 1)
When you start the fi re, the chimney is still cold and there is little draught. This
means that the chimney’s capacity to draw in air is limited. That is why the air
supply has to be assisted by opening the locking slider (and/or the door) and air
supply slider. Use dry, fi ne wood and some scrunched-up paper or fi relighters to
start the fi re.
