- any fl ammable fl uids (including methanol

is not permitted.
ENVIRONMENT!
Combustion of the materials listed above not
only gives off unpleasant odours, but also
generates emissions that damage the environ-
ment and are harmful to health.
Combustion of non-permitted fuels constitutes
a violation of the German Federal Immission
Control Act.
Improper fuels and their combustion residues
can be detrimental to the functioning and ser-
vice life of the stove and chimney – use of such
fuels voids both the warranty and guarantee.

10. Regulating the Combustion Air

To effectively guide the required volume of air to the right
places, a customized air fl ow system has been developed for
your Hase stove.
When lighting the fi re and adding fuel, you can use the primary
air and secondary slider to regulate the combustion air.

10.1 Primary Air

The primary air is guided through the grate and into the fi re
box from below, which allows the stove to reach the required
fi re box temperature more quickly during the warming up
phase.

10.2 Secondary Air

The secondary air is guided into the fi re box from the top, via
air ducts in the stove. It supplies the fi re box with the volume
of preheated oxygen necessary to completely burn off the
wood gas and reduces the build up of soot on the fi re box
windows.
For regulating the secondary air, the following general rule
applies: a small fi re requires little secondary air; a large fi re
requires ample secondary air.
WARNING!
If the secondary air slider (Fig. 5/II) is closed
too tightly, there is a risk that the fl ue gases
will not burn completely (smouldering fi re),
that soot will build up on the fi re box window,
or that the amassed wood gases will burn
explosively (overfi ring/defl agration).
Burning wood when the primary air slider
(Fig. 5/I) is opened too wide poses the risk of
overheating the stove (forge fi re effect).
CAUTION!
During operation, the secondary air slider
(Fig. 5/II) should never be completely closed.
In contrast, however, the fi re box door and ash
compartment must always be tightly shut.

11. Fuel Load Sizes and Thermal Output

The thermal output depends on the amount of fuel you put in
the stove. When adding more fuel, please do not exceed the
maximum fuel load size of 2,5 kg. Exceeding the maximum
fuel load size leads to a danger of overheating, which can
result in damage to the stove and the risk of a stove fi re.

NOTE!
To attain a thermal output of approx. 7 kW,
burn wood logs that weigh 2.0 kg and are no
longer than 30 cm in length for about 50 min.
(1.6 kg / 60 min. at browncoal briquettes)
NOTE!
To attain a thermal output of approx. 4.5 kW,
burn wood logs that weigh 1 kg and are no
longer than 25 cm in length for about 45 min.
(1 kg / 60 min. at brown coal briquettes).
The Luno is intended for intermittent operation, please only
apply one fuel layer at a time.
