  • Page 11: Fuel

    8. FUEL The EG MULTIFUEL multi-fuel boiler is designed to burn biomass, which can be woodchips and wood pellets. Fuels such as sawdust, briquettes, nut shells or fruit stones must not be burned in EG Multifuel boilers. Incineration of the above may void the warranty. Do not use too large pieces of biomass, as this can lead to wear of the feed screw and gearmotors in a short period of time, as well as blockage of the feed system.
