Regulation of combustion air

„II" ..... Ignition position, max. heat output
„I"....... Nominal heat output with billet wood
„I"....... Nominal heat output with wood briquettes
„0" ..... Obtain glow
As the secondary air also contributes to the
cleanliness of the glass pane, the operating lever
should be set on "I" minimum. This also applies in the
event of low-load operation.
When not operating the lever should be set on"0", to
reduce the cooling down of the room.
