In the following paragraphs, some notes are given that have to be observed in order to achieve the best performance of
the purchased product.

LOCATION OF INSTALLATION OF THE COOKER
Figure 3 lists the minimum distances that must be observed when setting up the cooker, regarding the materials and
inflammable objects.
Protect from heat radiation of the flame all the objects that could catch fire due to exposure to excessive heat.
Wooden floors or those made of flammable material must be protected by non-flammable material, for example sheet metal
with a thickness of 2-3 mm.
The cooker can be installed between the two walls.
The minimum distance to be applied between the cooker and walls must be 10-20 cm.
Any wooden beams placed above the cooker must be protected with non-flammable material.
If the previous conditions are not met, the cooker cannot be installed.

AIR USED FOR COMBUSTION
- The cooker takes the air during operation from the room where it is located.
- The outside air can be supplied directly through a tube of 80 mm diameter with a seal (Figure 4).
- The maximum length of the air supply pipe is 4.5 m with a maximum of 3 knees at 90
˚
.
- The air inlet hole must be set at a height of about 20-30 cm from the ground.
- One grid for continuous ventilation must be installed outside. In very windy areas exposed to rain and wind, protection
against rain and wind must be foreseen.
- Ensure that the air inlet is positioned so that it cannot be accidentally blocked.
- In case it is impossible to achieve a direct supply of external air through the wall behind the cooker (the wall is not outer),
an opening must be made on one of the outer walls of the space in which the cooker is located.
- If the room does not have outer walls, it is possible to make an outer opening in the adjacent room and provide constant
supply of air through a grid placed on a wall between these two rooms.
- If the cooker is placed in the room with air extraction grilles, or if it is placed in a room with already existing appliances that
take air from the room, always take care that the amount of air supply to the room is sufficient to ensure the safe operation of
the cooker and existing appliances.
It is forbidden to supply air for combustion from rooms where there are risks of fire, such as garages, warehouses, depots,
etc.
A - chimney cap
B - inspection opening
C - slope
H - height
- If one or more fans for the extraction of air (aspirators) are installed in the room where the
cooker is placed, it is necessary to check if the poor operation of the cooker is caused by the
insufficient air required for combustion.
