Mareli Systems

Pellets are stored in a hopper. Mareli hoppers have a 45-degree tilt. The screw conveyor pipe must be placed 

therein. The Screw conveyor draws pellets from the hopper and feeds the burner through a flexible connection. 

Dosing is controlled by the control unit by changing the operating time of the screw conveyor. The initial load-

ing of the screw conveyor with pellets (filling the screw conveyor pipe) is carried out when the screw conveyor 

plug is connected to a normal 230V/50Hz outlet. As pellets start to fall through the flexible connection, the 

plug is shifted to the burner.

Important

: For ensuring normal operation of the burner a 20 Pa chimney draught is required. After starting 

the burner, wait for about 3 hours for the chimney to be warmed up and measure the draught. Install addition-

al chimney fan (controlled by the control unit of the burner) if necessary.
The heat exchange surface is made of high quality low-carbon stainless steel. Wear is extremely slow, and 

cleaning is done with a soft damp cloth without any cleaners.
