Section 3 – Maintenance & Servicing 
3.1  REMOVAL OF DEBRIS OR SOOT                 18” Inset 
Allow the appliance to cool for two to three hours before removing all of the fibre components for cleaning purposes. Once all the fibre is 
removed, check that no debris is located in the burner holes of the appliance. If any debris is located, carefully remove any foreign matter 
from the burner holes. 
Any soot deposits or debris left on the fibre components may be removed by using a soft brush. Brush with the component held away from 
your face so that you avoid inhaling the dust. CROSSLEE plc DOES
 NOT recommend the use of a normal vacuum cleaner, which may 
blow dust back into the room. 
To ensure that the release of fibres from these RCF articles is kept to a minimum, during installation and servicing, CROSSLEE 
recommend that a HEPA filtered vacuum is used to remove any dust and soot accumulated in and around the appliance before and after 
working. When replacing these articles, CROSSLEE recommend that they are NOT
 broken up, but are sealed in heavy duty polythene 
bags and clearly labelled as RCF
 WASTE. This is not classified as hazardous waste and may be disposed of at a tipping site licensed for 
the disposal of industrial waste. Protective clothing is not required when handling these articles although CROSSLEE recommend you 
follow the normal hygiene rules of not smoking, eating or drinking in the work area and to always wash your hands before doing so.
