2. APPLIANCE DATA
This product uses fuel effect pieces and a burner compartment rear wall
containing Refractory Ceramic Fibres (RCF), which are man-made vitreous
silicate fibres. Excessive exposure to these materials may cause irritation to eyes,
skin and respiratory tract. Consequently, it is important to take care when
handling these articles to ensure that the release of dust is kept to a minimum. To
ensure that the release of fibres from these RCF articles is kept to a minimum,
during installation and servicing we recommend that you use a HEPA filtered
vacuum to remove any dust and soot accumulated in and around the fire before
and after working on the fire. When replacing these articles we recommend that
the replaced items are not broken up, but are sealed within a heavy duty polythene
bag, 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, but we recommend
you follow the normal hygiene rules of not smoking, eating or drinking in the work
area and always wash your hands before eating or drinking.
This appliance does not contain any component manufactured from asbestos or
asbestos related products.
* When converted using Kit 0595221
The appliance data label is located on a plate at the base of the fire. This can be seen by
removing the lower hanging trim.

Figure 1. Hearth and Fireplace Opening Dimensions

Where no specific instructions are given, reference should be made to the relevant
British Standard Code of Practice.
3.2 In the United Kingdom, as supplied, this appliance can be installed in the
following situations: -
3.2.1 A masonry chimney with a minimum diameter of 175mm (7”) free from any
obstruction, and with any damper or restrictor plate in the chimney removed or secured,
and having a minimum effective flue height of 3m (10ft). A masonry chimney having a
correctly installed flue liner to BS715 and with a minimum flue diameter of 125mm is
also acceptable. Chair brick removal may not be required providing at least 50mm
clearance is available from the flue outlet to any fireplace component. The appliance is
designed to cater for low lintel installations (min height 505mm) providing a minimum
distance of 25mm is maintained between the lintel and the front face of the fireplace
(i.e. 25mm rebated fire surround).
3.2.1.1 ‘Hole-in-the-wall’ Installations
 It is recommended that a hearth should be installed as in figure 1.
 If a hearth is not fitted, the fire must be installed so that the distance from the
base of the fireplace opening in the wall to the finished floor level is at least 72mm.
3.2.2 To a fireplace incorporating a metal flue
box conforming to BS715 with a minimum
internal depth of 150mm. Incombustible
mineral wool insulation of not less than
50mm thickness must be applied to the top
surface of the firebox (See figure 2) and it
must stand on a non-combustible hearth. See
figure 1.
3.2.3 To a fireplace that has a precast
concrete or clay flue block system
conforming to BS1289 or BS EN 1806. The
appliance is suitable for installations
conforming to older versions of BS1289 as
well as the current edition. The flue blocks
must have a minimum width not less than
63mm and a cross-sectional area not less than
13,000mm2.Older editions of BS1289
required a cross-sectional area of 13,000mm2.
Page 7
INSTALLER GUIDE
Figure 2. Metal Flue Box

The current revision of the standard requires 16,500mm2. This appliance is suitable in
both cases. The total depth of the opening measured from the finished front of the
fireplace (Including plaster, surround etc.) must be not less than 120mm. See figure 3.
The current versions of BS1289 and BS EN 1806 recommend that there should be an air
space or insulation between the flue blocks and the plaster because heat transfer may
cause cracking on directly plastered
flues. However, generally this appliance
is suitable for installations under all
circumstances unless there is a history of
cracking problems. Remember that faults
such as cracking may be caused by
poorly built and restrictive flues, e.g.
mortar extrusions, too many bends, flue
heights below three metres, restrictive
terminations, etc.
3.2.4 If the fireplace opening is greater
than the acceptable dimensions given in
this guide, do not use the back of a fire
surround or marble to reduce the
opening. This may cause cracking of the
surround back or marble.
3.3 The following flues are suitable:
 225mm x 225mm conventional brick
flue.
If a flue liner is used, it must be a
minimum of 125mm diameter. The liner
must be sealed to the surrounding area
above the fireplace opening and to the
top of the chimney. An approved terminal
must be fitted.
 A properly constructed precast flue conforming to B.S 1289 or BS EN 1806.
 A flue pipe with a minimum diameter of 127mm. See B.S 6461 Part 1 for suitable
materials. Metal flue pipes must comply with B.S 715.
3.3.1 The minimum effective height of the flue must be 3m.
3.3.2 The flue must be clear of any obstruction and its base must be clear of debris.
3.3.3 The flue must be completely sealed so that combustion products do not come into
contact with combustible materials outside the chimney.
3.3.4 The flue must serve only one fireplace.

INSTALLER GUIDE
Figure 3. Pre-cast Fireplace

3.4 The flue must conform to BS 5440: Part 1 in design and installation.
The flue, measured from the bottom of the fireplace opening to the bottom of the
terminal, shall be not less than 3m in actual vertical height. When calculated in
accordance with BS 5440: Part 1 Annex A, the minimum equivalent height of the flue
shall be 2.0m of 125mm dia. flue pipe.
3.5 The flue must not be used for any other appliance or application.
3.6 Any chimney dampers or restrictors should be removed. If removal is not
possible they must be fixed in the open position.
3.7 If the appliance is intended to be installed to a chimney, which was previously
used for solid fuel, the flue must be swept clean prior to installation. All flues should be
inspected for soundness and freedom from blockages.
3.8 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
3.9 The appliance must be mounted behind a non-combustible hearth (N.B.
conglomerate marble hearths are considered as non-combustible). The appliance can be
fitted to a purpose made proprietary class “O”-150°C surround. The hearth material
must be at least 12mm thick. The periphery of the hearth (or fender) should be at least
50mm above floor level to discourage the placing of carpets or rugs over it.
The appliance must not stand on combustible materials or carpets (See figure 1).
3.10 The front face of the fireplace should be reasonably flat over the area covered by
the hotbox top and side flange seals to ensure good sealing. These faces should be made
good if necessary.The fireplace floor should be reasonably flat to ensure that a good seal
with the hotbox can be made.

INSTALLER GUIDE

3.11 The minimum height from the top surface of the hearth to the underside of any
shelf made from wood or other combustible materials is detailed below.
• For a shelf up to 150mm deep: Minimum height = 750mm.
• For a shelf deeper than 150mm: 150mm + 12.5mm for every 25mm depth over
150mm. (See Graph 1)
3.12 Note that soft wall coverings (e.g. embossed vinyl, etc.) are easily affected by
heat. They may scorch or become discoloured when close to a heating appliance. Please
bear this in mind when installing.
3.13 The appliance must not be installed in any room, which contains a bath, or shower
or where steam is regularly present.
3.14 An extractor fan may only be used in the same room as this appliance, or in any
area from which ventilation for the appliance is taken, if it does not affect the safe
performance of the appliance. Note the spillage test requirements detailed further on in
this manual. If the fan is likely to affect the appliance, the appliance must not be
installed unless the fan is permanently disconnected.
3.15 Normal adventitious ventilation is usually sufficient to satisfy the ventilation
requirements of this appliance. In GB reference should be made to BS 5871 Part 2 and
in IE reference should be made to the current edition of IS 813 “Domestic gas
