Basic opening sizes (all dimensions in mm)
The basic opening dimensions for the appliance are as follows;
The opening must be within these sizes in order to accommodate the full depth of
the fire box in non-combustible applications. Applications involving combustible
materials e.g. timber battens in false chimney breasts, must use appropriate clear-
ances and insulation methods as described in the relevant section of these instruc-
tions. Opening depth
‘c’
includes any plaster, cement or infill/back panels that form
part of the installation.
Consideration for cable fixings, any hearth that may be required etc. should be made
in addition to the basic sizes given in table 1.
•
Cable fixings at rear - allow an extra 20mm depth.
•
Hearth to be installed - allow the height of the hearth (minimum 50mm).
The appliance must be sited on a solid base (indicated in figure 2). This base may be
combustible (i.e. laminate or wooden flooring) but must not be carpet or fabric of
any kind. If the room in which the appliance is to be installed is carpeted or has a
fabric floor covering then a small solid hearth will be required, meeting the dimen-
sions specified in table 1 and illustrated in figure 3.
In all installations, the wall or back panel of the installation must be flat, non-com-
bustible and meet the dimensions specified in table 1 and illustrated in figure 2.
The appliance may be installed as a ‘hole in the wall’ type installation, however a small
hearth or ledge must be provided to support the base of the appliance and decora-
tive facia. In this situation the thickness of the hearth or ledge may be as desired, but
it must have the strength to support the weight of the appliance and the facia.
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.
The wall/back panel for the opening must always be non-combustible. Bare plasterboard must be protected by non-combustible
plaster or replaced with non-combustible material (e.g. Superlux board). Any gap between wall boards and the wall must be filled
using glass fibre insulation, silicone mastic or similar material to prevent heat ingress.
Any type of fire surround used with this appliance must be adequately sealed to the wall and floor to prevent excess draughts
around the back of the fire. The temperature rating of any surround used must be 150°C minimum.
Clearances to the sides of the appliance are 100mm (4”). Clearance to the front of the appliance is 500mm (20”).
