3. FUEL CHARACTERISTICS AND DESCRIPTION OF THE COOKER
3.1 FUEL CHARACTERISTICS
- Pellet is a fuel of cylindrical shape, produced from different types of wood, mechanically pressed, in compliance with the
regulations on environmental protection.
It is the only type of fuel envisaged for this type of cooker.
- The efficiency and thermal power of the cooker may vary depending on the type and quality of the wood pellets used.
- Burning of different types of pellets may require modification or adjustment of program settings.
In order for the cooker to work properly, the pellets must have the following characteristics:
- diameter Ø 6 mm
- maximum length 30 mm
- maximum moisture content 8% to 9%
The cooker is equipped with a pellet storage with the capacity specified in the table of technical characteristics.
The storage cover is on the upper side of the cooker.
The proper operation of the cooker depends on the type and quality of pellets, since the heat obtained from the different
types of pellets can be of different intensity.
The manufacturer of the cooker does not bear any responsibility for poor operation of the cooker in the case of use of pellets
of inadequate quality.
It is forbidden to use the cooker for incinerating waste.
3.2. PELLETS STORAGE
Pellets must be stored in a dry and well-ventilated room, at a temperature of 10˚C ÷ 25˚C. A cool and moist pellet stored in a
humid room, with temperature below 5˚C, has reduced thermal power and requires additional cleaning of the cooker.
PELLETS CAN NOT BE KEPT AT A DISTANCE OF LESS THAN 2 METERS FROM THE COOKER. Handle pellets carefully, do not
break it.
WARNING: If a sawdust or small (broken) pellets are fed in the fuel storage, it may block the pellet insertion. Such pellets
may lead to burnout of the electric motor that drives the pellet insertion mechanism, or to damage of the gear unit that works in
conjunction with the electric motor. If you notice such pellets at the bottom of the pellets storage, that is, at the bottom of the
auger when the storage is empty, vacuum it with a vacuum cleaner by dragging the vacuum cleaner pipe through the openings
of the storage grate.

When lifting, avoid sudden movements.
Make sure that the forklift truck has a load capacity greater than the weight of the cooker to be lifted.
The forklift operator will be solely responsible for raising the load.
Prevent children from playing with parts of packaging (for example: foils and polystyrene). Risk of choking!
5. PREPARATION OF THE SPACE FOR INSTALLATION
5.1. PRECAUTIONARY MEASURES
The responsibility for the work done at the point of installation is entirely on the user.
The user must comply with all local, national and European safety regulations.
The cooker must be set up on the floor of the appropriate load capacity.
Cooker assembly and disassembly instructions are exclusively intended for authorized installers.
The installer must, prior to commencing the assembly or disassembly stage of the cooker, implement the safety measures
prescribed by law, and in particular:
A) must not work in interfering conditions;
B) must verify that the personal protective equipment is complete and in good condition;
C) must wear protective gloves;
D) must wear protective shoes;
E) must use tools with electric shock insulation;
F) must ensure that the place where assembly or disassembly is carried out is free of obstacles.
5.2. GENERAL MEASURES
There are many factors that influence the efficiency of burning - in terms of thermal performance and low emissions of
contaminants (CO - carbon monoxide). Some factors depend on the cooker, but some depend on the characteristics of the
space, installation and the degree of regular maintenance of the product.
Some of the more important factors are:

6
-the amount of incoming air used for combustion;
-characteristics of the system for combustion products discharge;
-quality of pellets (humidity and dimensions).
In the following paragraphs, some notes are given that have to be observed in order to achieve the best performance of
the purchased product.
5.3. 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.
Figure 3 Figure 4
5.4. 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.
Figure 5

7
5.5. SMOKE EXTRACTION
- The tubes to be used for smoke extraction must be rigid, made of aluminum sheet (at least 1.5 mm thick wall) or stainless
steel (at least 0.5 mm thick wall). For lengths up to 5m, use pipes of 80mm diameter, with seals, and for lengths greater than 5m,
pipes of 100mm diameter, with seals.
- It is advisable to insulate the pipes with insulating material (with a mineral wool of at least 2 cm thickness), or use steel
pipes with a double wall, where the first vertical part, if it is internal, does not have to have double layer.
- It is mandatory that the first vertical part has a length of at least 1.5 meters in order to guarantee proper smoke extraction.
- It is advised to make at most 5 to 6 changes of direction using knees of 45-90˚or T joints.
- Always use T joints with inspection openings for each horizontal or vertical change of direction of the flue pipe.
- Horizontal parts must not have a length greater than 2-3 m, with an inclination of at least 5%.
- Anchor pipes to walls.
Flue pipes MUST NOT BE CONNECTED:
- To a chimney used by other smoke generators (furnaces, fireplaces, etc.)
- To the air extraction system (aspirators, valves, etc.) even if it is connected by pipes.
It is forbidden to install valves for preventing the draft.
In case of length of the flue pipe greater than 5 meters or in the conditions of poor airflow (the presence of many curves,
inadequate ending of the outlet, etc.), the extraction of smoke might be inappropriate. In this case, it will be necessary to
change the operating parameters (extraction of smoke and feeding pellets) in order to adjust the cooker to the actual
characteristics of the chimney.
Contact technical support.
5.5.1 Smoke extraction through the roof chimney
The smoke extraction chimney must be constructed in compliance with the regulations, both in terms of dimensions and in
terms of materials used for its construction.
RUINED chimneys, made of inadequate material (fibrous cement, galvanized steel, etc... whose interior is not smooth and
porous) are inadequate and may impact proper operations of the cooker.
Smoke extraction through a traditional chimney (Figures 7 and 8) can be executed only if the following rules are observed:
- Check the condition of the chimney - in the case of an old chimney, its repair is advised by introducing a properly insulated
steel tube (mineral wool, vermiculite).
- Smoke can be taken directly into the chimney equipped with an inspection opening.
The smoke extraction system (chimney) made of metal pipes must be grounded in accordance with existing standards and
legal regulations.
This grounding must be independent of the cooker’s grounding.
When installing the flue pipes start with T-
branch (2), to which a condensate vessel with an outlet
for condensate (1) is mounted. Then install a flue pipe
(3) and penetrate the wall with an 90° elbow (4).
