Log size
The size of the wood logs can also affect the efficiency of the
product.
- It is essential for the wood to be arranged on the grate on top of a
layer of embers.
- The logs must not touch the aluker or the glass window nor must
they be put on top of each other. Place the wood as shown in the
figure30.
- We therefore recommend using logs of the following size:
perimeter approx. 30/35 cm;
length approx. 20–25–30 cm according to the type of hearth.
3.2 Adjusting the combustion air - Fig. 31
The nominal heat output is determined with the air dampers. Take
note of the positions given in the table below, according to the fuels
being used.
The positions given below naturally refer to nominal output. Since
the output also depends on atmospheric and climatic conditions and
therefore on the draught, the most suitable position will be learned
with experience.
Adjustment can be made as shown in the figure to the side.
an excessive amount of fuel and excessive opening of the air
dampers compared to table values, leads to an increase in
heat of the appliance, decrease in efficiency and increase in
the consumption of wood.

3.3 Lighting for the first time
There are two important stages when lighting the appliance for the first time: the operating test and start-up.
1.
Operating test
- Before carrying out the operating test, check that everything has been installed correctly (see section GENERAL RULES).
- Start with the lighting stage (see paragraph LIGHTING).
- The first load should be reduced by 50% of the normal recommended amount.
Should smoke come out:
• do not open the door of the stove;
• close the combustion air dampers (MINIMUM position) only on appliances with combustion air damper;
• let the fire go out slowly;
• air the room before staying in it;
• check the cause of malfunctioning.
Do not extinguish the fire with water as this could damage the grate
