Adding Fuel / Heating At Nominal Thermal Output; Heating With Brown Coal Briquettes; Banking The Fire And Raising The Temperature; Heating At Low Thermal Output - HASE Luno Mode D'emploi

14. Adding Fuel / Heating at Nominal Thermal Output

More fuel should be added to the fi re when the fl ames from
the previous burning off phase have just gone out.
Adding Fuel / Heating at Nominal Output
Procedure
Close primary air
Adjust secondary air
Close fi re grate.
Add two logs weighing approx.
2 kg in total. Place logs with
one end to the front of fi re box.
Only add a single layer of fuel.
Close fi re box door.

15. Heating with Brown Coal Briquettes

Wood should be used for the warming-up phase and when
adding fuel for the fi rst time, see "Warming-up Phase". As
soon as a basic glowing fi rebed is reached, place 2-3 brown
coal briquettes on the grate in the middle of the fi rebox, kee-
ping a fi nger's width between the briquettes, and use the
following procedure and settings:
Position of
Control Elements
Set primary air slider (I),
all the way to the right.
Set secondary air slider (I),
all the way to the left.
Open primary air completely.
Push in fi re grate slider.
Open fi re box door.
Adjust secondary air.
Open fi re grate.

Heating with Brown Coal Briquettes
Procedure Position of
Control Elements
Set primary air slider (I),
all the way to the left.
Half open secondary
air slider [II]
Pull out fi re grate slider.

16. Banking the Fire and Raising the Temperature

Keep the stove set as described above until the brown coal
briquettes are thoroughly burnt. Then close the primary air (I)
and the fi re grate. Slide the secondary air slider (II) to position
2/3.
NOTE!
While the stove is in operation, the secondary
air slider should never be completely closed.
To raise the temperature of the fi re, stir up the rest of the
glowing embers with the fi re grate slider. Open the primary air
(I) and add new logs to the fi re.

17. Heating at Low Thermal Output

(during Transitional Seasons)
You can vary the thermal output of your Luno by adjusting the
quantity of fuel used.
NOTE!
Do not attempt to slow down the combustion
by reducing the air supply. When heating with
wood, this can result in an incomplete burning
process and pose the risk of an explosive-like
combustion of the accumulated wood gases
