CLEARANCES TO COMBUSTIBLES
Clearances to combustible materials
Combustible materials are defined as wood, fabrics, or other materials likely to combust if exposed to
flame. Generally, any material, which is likely to discolour, melt or misshape when exposed to moderate
heat, should be considered as a combustible material or surface.
Clearance to the sides of the appliance are 100mm(4in) but curtains, drapes and other fabrics are not per-
mitted within a distance of 500mm(20in) of the appliance sides. No such materials are permitted directly
above the appliance regardless of distance.
The minimum clearance to the ceiling above the appliance is 800mm measured from the top of the appli-
ance glass panel.
Combustible materials should not be positioned directly in front of the appliance within a distance of one
metre.
Under no circumstances should any electrical equipment e.g. plasma screen TV sets etc. be positioned on
the wall above the appliance. The appliance is designed to be wall mounted alone and not in conjunction
with any type of combustible fire surround. No combustible shelves should be positioned on the wall above
the appliance. It should be established that any mirrors or picture frames etc. to be positioned on the wall
above the appliance are able to withstand prolonged moderate heat before proceeding with their installa-
tion.
The back of the appliance may be installed directly onto a combustible wall, providing it is relatively flat
and does not interfere with the various vent holes in the back panel of the appliance. The wall must be
structurally sound and constructed from a material capable of withstanding moderate heat. Finished plas-
ter, conventional wall paper and dry-lined plasterboard are examples of suitable materials. Materials such
as flock, blown vinyl and embossed paper which are sensitive to even small amounts of heat should be
avoided as scorching and or discolouration may occur over time.
The appliance must not be positioned vertically within 100 mm of a carpeted floor, rugs or fabric materi-
als of any kind. This dimension is measured vertically to the bottom of the appliance firebox.
Clearances to non-combustibles
Non combustible surfaces are defined as brick, metal, marble, concrete etc. and also a number of man-
made materials impervious to flame. If in doubt refer to the material manufacturer for further information
before proceeding with installation.
Clearances to the sides of the appliance are 100mm (4in). Clearance to the front of the appliance is 500mm
(20in).
The back of the appliance may be installed directly onto a non-combustible wall, providing it is relatively
flat and does not interfere with the various vent holes in the back panel of the appliance.
A non combustible shelf of any depth may be positioned above the appliance provided it is no closer than
400mm from the top of the appliance glass panel and the wall above the appliance is non combustible.
The appliance must not be positioned vertically within 60mm of a solid floor (i.e. wood or stone) or hearth.
This dimension is measured vertically to the bottom of the appliance firebox.
VENTILATION AND ROOM SIZE
Purpose provided ventilation of 100cm
2
is required for this appliance. An openable window or equivalent
is also required. The appliance should not be installed within 500mm of any air vent.
Any ventilation fitted must comply with BS 5871 part 2 and BS 5440 part 2. Ventilation fitted under, or
within immediate vicinity of the appliance must not be used as it may adversely effect performance of the
combustion monitoring system (ODS) system.
The requirements of other appliances operating in the space or room must be taken into consideration
when assessing ventilation requirements, this will have been carried out by your CORGI registered
installer.
A supply of fresh air into the room is advisable to maintain temperatures within limits. The appliance
MUST NOT be installed in a bedroom or bathroom. For Republic of Ireland, see relevant rules in force.
