ADVICE ON HANDLING AND DISPOSAL OF FIRE
CERAMICS
The fuel effect and side panels in this appliance are 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.
5.2 To clean the burner system, firstly depress the front door
centrally on the RH side and the door will release allowing
you to open fully. See diagram 1.
1
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.

ADVICE ON HANDLING AND DISPOSAL OF FIRE
CERAMICS
The fuel effect and side panels in this appliance are 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.
AR1195
4.4 Place log B on the first stud. The recess on the underside of
the log should locate on the top of log C. See diagram 6.

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.
4.1 Place log A on to the burner. Ensure the rear of the log
touches the rear of the burner. See diagram 3.
