Page 8: General Information
Mareli Systems 1. GENERAL INFORMATION Steel boilers LCG, with an rated thermal output 22, 32, 40 and 50 kW are constructed for wood fir- ing and aimed for heating of small and middle sized premises. Due to the applied wood gasification principle, wood is totally burned. - Page 9 Mareli Systems 2. POSITIONING AND ASSEMBLY The installation of the boiler has to be carried out by the authorized person. We suggest the boiler to be installed on the solid concrete basis, which height is between 50-100 mm. The boiler room has to be absolutely protected from freezing and properly ventilated.

Page 15: Boiler Thermal Protection
Mareli Systems BOILER THERMAL PROTECTION According to European EN standards, boiler thermal protection must be installed in closed heating system. Boiler is factory prepared for installation of thermal protection. IMPORTANT: In case of any damage of boiler installed in the closed heating system due to its overheating, and boiler or system are not equipped with any thermal protection at all, or do not have properly installed thermal protection, guarantee will not be applied. -
