Never use mineral based solid fuels in wood burning appliances (see Introducing wood as a fuel). Mineral fuel burns hotter than wood and must always be burnt on a grate please be sure to insert the solid fuel grate in a multi-fuel stove before burning mineral based solid fuels.  


Always buy solid fuel from an Approved Coal Merchant and look for the approved Coal Merchant logo (see Coal Merchant Federaton or the Solid Fuel Association)
