The appliance is equipped with an easy-to-use handle for adjusting the air control.
For the various positions of the control please see the following illustrations. To ensure
proper combustion process it is very important to supply the correct quantity of air at
the right time and place. The adjustment range made from factory may not be altered
for increasing firing for any reason.
Primary air is defined as combustion air for burning the mass of wood and stimulates
production of volatile gases.
Secondary air is used to burn off the gases at high temperatures (above 1,000°F/540°C)
The warm secondary air runs along the glass, keeping it free of soot.
Tertiary air is supplied through the tertiary air channel in the back of the burning cham-
ber and through the baffle plate above the burning chamber. Tertiary air helps to com-
bust the remaining gases.
When positioning the air control between Pos. 2 and 3 optimum utilization of the en-
ergy contents of the wood is obtained, because of sufficient oxygen for combustion.
When the flames burn bright and yellow, the control has been adjusted correctly. Find-
ing the correct position takes some trial and error, but is easy to find.
Never close the air control completely before the flames are no longer visible. A typical
error is to close the control too soon, because the heat gets too intense. This results in
the appearance of a dark cloud of smoke from the chimney and that means the energy
value of the wood is not being used properly.
It is important for proper control of the fire that the instructions in the manual are fol-
lowed and the stove door normally is kept closed. It is also necessary to keep the seals
in a good condition.
