This product uses fuel effect pieces and burner compartment wallscontaining Refractory Ceramic Fibres (RCF), which are man-made vitreoussilicate fibres. Excessive exposure to these materials may cause irritation toeyes, skin and respiratory tract. Consequently, it is important to take carewhen handling these articles to ensure that the release of dust is kept to aminimum. To ensure that the release of fibres from these RCF articles is keptto a minimum, during installation and servicing we recommend that you usea HEPA filtered vacuum to remove any dust and soot accumulated in andaround the fire before and after working on the fire. When replacing thesearticles we recommend that the replaced items are not broken up, but aresealed within a heavy duty polythene bag, clearly labelled as RCF waste. RCFwaste is classed as a stable, non-reactive hazardous waste and may bedisposed at a landfill licensed to accept such waste. Protective clothing isnot required when handling these articles, but we recommend you follow thenormal hygiene rules of not smoking, eating or drinking in the work area andalways wash your hands before eating or drinking. Check that the appliance is clean and that soot or debris is not blocking the gapsbetween the ceramic fuel effect pieces causing an imperfect flame. Check that soot or debris is not impairing the electrode spark or pilot burner. Check that soot or debris is not blocking any of the slots in the main burner. After servicing, make sure that the ceramic walls are replaced and the ceramic fueleffect pieces are replaced correctly as described in the installer and owner guidesupplied with the ceramic fuel effect.
