6. Arrangement of Fuel Bed

Advice on handling and disposal

of fire ceramics

The fuel effect of the log version of this

appliance is made from Refractory Ceramic Fibre (RCF), a material which is commonly used for this application.

Protective clothing is not required when

handling these articles, but we recommend you follow normal hygiene rules of not smoking, eating or drinking in the work area and always wash your hands before eating or drinking.

To ensure that the release of RCF fibres are

kept to a minimum, during installation and servicing a HEPA filtered vacuum is recommended to remove any dust accumulated in and around the appliance before and after working on it. When servicing the appliance it is recommended that the replaced items are not broken up, but are sealed within heavy duty polythene bags and labelled as RCF waste.

RCF waste is classed as stable, non-reactive

hazardous waste and may be disposed of at a licensed landfill site.

Excessive exposure to these materials may

cause temporary irritation to eyes, skin and respiratory tract; wash hands thoroughly after handling the material.

7. Log Layout

LOGS MUST BE POSITIONED ACCORDING TO THE

FOLLOWINGINSTRUCTIONSTOGIVETHECORRECT
