INSTRUCTIONS FOR USE

First firing

The stove has been treated with a
heat-resistant coating which hardens
at a temperature of approximately
250 ºC.
This hardening process causes the
production of smoke and malodorous
fumes, so the room must be very well
ventilated.
During the first firing, which should
be carried out using approximatly 1,0
kg. of wood, the stoking door must
be left slightly open and must not be
closed until the stove is cold. This is to
prevent the sealing rope sticking to
the stove.
Fuel
Your new stove is EN approved for
firing with wood fuel. You must
therefore only burn clean, dry wood
in your stove. Never use your stove to
burn drifwood, as this may contain a
lot of salt which can damage both the
stove and the chimney. Similarly, you
must not fire your stove with refuse,
painted wood, pressure-impregnated
wood or chipboard, as these materials
can emit poisonous fumes and smoke.
Correct firing using well seasoned
wood provides optimal heat output
and maximum economy. At the same
time, correct firing prevents environ-
mental damage in the form of smoke
and emmissions and also reduces the
risk of chimney fires. If the wood is
wet and inadequately seasoned, a
large proportion of the energy in the
fuel will be used to vaporise the water,
and this will all disappear up the chim-
ney. Thus it is important to use dry,
well seasoned wood, i.e. wood with
a moisture content of no more than
18%. This is achieved by storing the
wood for 1–2 years before use. Pieces
of firewood with a diameter of more
than 10 cm should be split before
4
storing. The pieces of firewood should
be of an appropriate length (approx.
25–30 cm) so that they can lie flat on
the bed of embers. If you store your
wood outdoors, it is best to cover it.

Chimney fires

In the event of a chimney fire – which
often results from incorrect operation
or protracted firing with moist wood
– close the door and shut off the se-
condary/start-up air supply to smother
the fire. Call the fire department.
Lighting and combustion
To open the flow of secondary air, use
the operating handle at the front of
the stove. The secondary airflow is
completely open when the handle is
to the left side position, fig. 1.
Shut off the secondary airflow gra-
dually by moving the handle to the
right. The supply is completely shut off
when the handle is to the right side
position, fig. 2.
