6. Putting the Furnace into Operation
Before the first use of the furnace, you need to wipe the enamel surfaces with a damp cloth in order to
avoid staining. Painted surfaces are not to be touched, nor are there any objects to be left on the furnace
in order to prevent paint damage.
After reading the instructions, the first furnace putting into operation follows. When the furnace is fired for
the first time, open the windows as the corrosion protection creates an unpleasant odour and some
smoke. This is normal occurrence, and it will stop after a short time. If necessary, turn on the fan to make
rapid air circulation. Fire up to a maximum temperature for at least one hour. If during the first firing the
maximum combustion temperature is not reached, there may be problems with the odour later.
People including pregnant women and young children should be out of the room during the firing phase.
Keep in mind that some of the furnace built-in parts (drain pipe, loading door, furnace door) become very
hot while the furnace is in operation, and there is a risk of burns. Keep small children away from the
furnace.
6.1 Putting the Furnace into Operation and Its Running
- Open the primary air regulator all the way (Fig. 1, position 2)
- Open the furnace door
- Load the wood wool, wood chips or paper
- Put two pieces of wood before this
- Fire
- Close the furnace door
- Let the wood burn
After the glow is formed, load new fuel through the fire opening, and adjust the air regulator for primary air
according to the type of fuel. Never put new fuel onto the flame!
A certain amount of smoke is released when the furnace door is opened suddenly. When adding fuel, you
should open the furnace door slowly as to avoid the suction of the smoke. This way, you stop the smoke
from coming into the room.
Nominal heating power can be achieved with the following amounts of fuel, and the following adjustments
to the primary air regulator.

The furnace may only be used with natural, cleaved wood and brown coal briquettes. Cleaved wood is
inserted using wooden pieces that are 32 cm long, while with brown coal you insert a certain number of
pieces.
Lacquered, painted, laminated and impregnated heated wood or wood processed using adhesives cannot
be used in the furnace. In such a case, any guarantee or responsibility of the manufacturer shall cease to
exist. Heating wood you intend to use must be dry (wood humidity 20%). The wood is usually dry after
two years of storage in a dry and well ventilated place. Wet wood has a low calorific value and leaves
deposits in the exhaust stacks and in the chimney.
Under the most adverse weather conditions, interferences may be formed in the chimney (e.g. bad
weather). In such cases, the furnace may not be used for safety reasons.
