Combustion air slide valve
Operating lever for combustion air supply
● Operating lever on „0":
all slide valves closed
● Operating lever on „I":
Secondary slide valve completely open /
Primary air slide valve completely closed
● Operating lever on „II":
Secondary slide valve completely open /
Primary air slide valve completely open
Regulation of combustion air
Position of operating lever:
„II" ..Ignition position, max. heat output
„II" ..Nominal heat output with lignite briquette
„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 cleanli-
ness 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.
Fire grate
Operating lever for the fire grate
● With the help of the operating lever the fire grate can
be opened or closed to move the ash from the com-
bustion chamber to the ash pan by pushing the fire
grate back and forth.
● Primary air can only enter the combustion chamber
if the fire grate is set on open position.
● For heating operation with lignite briquettes, the fire
grate must always be in the open position.
Wood storage compartment
The wood storage compartment below the combus-
tion chamber is fitted with a magnetic pressure clo-
sure. It can be opened by lightly pressing on the but-
ton (Olsberg logo). Likewise it can be closed by light-
ly pressing.
Admixed air mechanism
The admixed air mechanism is pre-adjusted in such a
way that the admixed air flap opens when about 20 Pa
flue draught are reached and the flue draught is kept
nearly stable.
In case of strong draught variations pendulum noises
may be created. In this case the admixed air tap may
be fixed with the closing tab.
