Mareli Systems

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 .
