5. 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 1.5
kg. The fuel can be filled to the maximum height of
20 cm in the combustion chamber. Exceeding the
maximum fuel load size leads to a danger of over-
heating, which can result in damage to the stove
and the risk of a stove fire.
NOTE!
To attain a thermal output of approx.
5,5 kW, burn wood logs that weigh 1.3 kg
and are no longer than 25 cm in length for
about 45 min.
The Luno is intended for intermittent operation,
please only apply one fuel layer at a time.
5.1 Wood Briquettes
You can also fuel your Luno with wood briquettes
as specified in DIN 51731 Hb2 or of equal quality.
Please note that wood briquettes swell and expand
during combustion. As compared to the amount of
fuel when using logs, reduce the amount by approx.
10-20% based on the calorific value of the wood bri-
quettes. The control element settings and procedure
are the same as when burning logs.
6. Initial Operation
NOTE!
During shipment, condensation moisture
can accumulate in the stove’s interior,
which may possibly lead to the appear-
ance of condensation or water on the
stove or flue pipes. Please dry off these
damp areas immediately.
The surface of your stove was treated in a sand-
blasting machine before applying the colour coating.
Despite careful and thorough inspection, there may
still be some residual material in the stove body,
which can fall out when your stove is being insta-
lled.
NOTE!
To prevent any damage, please immedi-
ately vacuum up these small steel pellets
with a vacuum cleaner.
The first time a stove is operated, the heat devel-
opment causes the emission of volatile components
from the coating, sealing strips and lubricants, and
smoke and odours can occur.
At a higher combustion temperature, this one-time
process can take between 4 to 5 hours.
To achieve this higher combustion temperature,
please increase the fuel quantity recommended in
Section 8, „Adding Fuel/ Heating with Nominal Ther-
mal Output“, by approximately 25%.
CAUTION!
To prevent adverse effects on health, no-
body should stay in the room(s) during
this process unless absolutely necessary.
Make sure the room is well-ventilated and
open the windows and outside doors. If
needed, use a fan for faster air circulation.
If the maximum temperature is not reached during
the first heating operation, you may notice an odour
for a short period of time the next time the stove is
used as well.
