3.3 Protecting the floor
• Any combustible floor beneath a fireplace must have a floor protector that extends minimum 300mm at the front.
• If installed directly on combustible material, the floor protector must be made of a minimum 6mm thick cement sheet.
Non-combustible finishes can be applied to the floor protector (tiles, steel sheet, light concrete, etc).
• If the combustible floor is installed on concrete, you can replace the combustible material with non-combustible
material laid directly onto the concrete.
