The pellet burner is a compact modular design with integrated elec-
tronic control unit, consisting of the following components:
1. Combustion chamber made of high quality stainless steel;
2. Grill in the combustion chamber that is easily removed and al-
lows for easy ash removal;
3. Air duct, which ensures an even supply of air for combustion and
cooling elements of the burner;
4. Electric heater, which ignites the fuel, positioned beneath the in-
clined portion of the combustion chamber;
5. Fan, equipped with a sensor for adjusting speed;
6. Photo-sensor, which monitors the combustion process and ap-
plies a corresponding program;
7. Emergency temperature sensor to prevent “Backfire” in the pipe
of the unit;
8. Controller, which monitors and controls the burner and indicates
its mode of operation;
9. Connector auger, which realizes the power of the auger;
10. Interface panel equipped with indicator lights;
11. Transparent panel that shows the operation of the controller;
Electrically powered auger that transports fuel to the burner depending on the operating mode of the burner.
The screw consists of a compact geared motor with a built-in protection against overheating tube which trans-
ports fuel until it reaches the hole through which is supplied to the flexible tube. The flexible tube is made of
special heat-resistant material (which in the case of combustion does not emit toxic substances) and connects
the auger and pellet burner.

•
The installation must be performed by a qualified expert in the field of heating systems. The place and
way of connecting the burner must be chosen carefully, follow the safety instructions!!!
•
Never try to make changes to the torch! It is forbidden to use flammable liquids for ignition! Main-
tenance should be done by an adult who is familiar with the operating conditions! Introduction of
inflammable liquids in room with a working burner is strictly prohibited! Children should not be left
unattended in the room where the product is installed!
2. Measures to improve safety
•
The burner is controlled by a microprocessor.
•
The process of ignition is monitored by a photo sensor, if there is no ignite the first time, the micropro-
cessor feeds a second dose of pellets and ignition starts again. If after 2 attempts ignition does not take
place burner goes into standby mode.
•
If the hopper has no more pellets, the burner will not ignite.
•
Flexible pipe for transporting the pellets is made from heat-resistant material. If during operation tem-
perature sensor detects a temperature higher than 90 ° C, the auger conveyor stops and the burner is
turned off. The temperature has to fall below 90 ° C, for the safety measures to stop .
