Air regulation
Knob position Start - heating up:
In this position all ventilation openings are fully open.
In addition, the exhaust flap (oven side) opens to
reduce the flue gas. This ensures a better air draught
during heating up.
Knob position coal - nominal heat output:
When using brown coal briquettes, it is
recommended to adjust the applied amount of fuel to
the heat demand, so that only in case of large heat
output would it be fully loaded.(see max. deposition
rate „fuels“ page 14)
Knob in position coal - partial load operation:
If using lignite briquettes, first let the applied amount
burn through properly then adjust the knob to a
lower value to let it smolder.
Knob position wood - heating mode:
As soon as the fuel vividly burns (depending on the
air draught conditions), the knob must be adjusted to
position ‘wood‘.
