3 APPLIANCE DATA
This product uses fuel effect pieces, burner compartment rear wall and gaskets 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.
The appliance data label is on a plastic tie below the burner and is visible when the
bottom front cover is removed.

INSTALLER’S GUIDE
4.5 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.
4.6 The minimum allowable distance from the outside of the appliance case to a
corner wall having combustible material or any other combustible surface which
projects beyond the front of the appliance is 148mm at either side.
A minimum clearance of 100mm to any non-combustible surface at the right side is
recommended to allow satisfactory access to the control knob. No access clearance
from a non-combustible surface is necessary at the left side. See figure 1.
4.7 The minimum height from the top surface of the hearth to the underside of any
shelf made from wood or other combustible materials is shown in graph 1.
Graph 1 Combustible shelf clearances
4.8 The appliance must not be installed in any room, which contains a bath, or
shower or where steam is regularly present.
4.9 In the United Kingdom this appliance can be installed in the following
situations: -
4.9.1 To a fireplace complete with surround and hearth complying with B.S 1251. The
required fireplace, hearth, debris catchment area and clearance dimensions are shown in
figure 1.
Page 7
INSTALLER’S GUIDE
4.9.2 To a fireplace incorporating a twin walled metal flue box complying with the
constructional requirements of the current edition of BS 715 and standing on a noncombustible base. The dimensions of the flue box must conform to the opening shown
in figure 1. For flue details see section 4.10.
4.9.3 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
13,000mm
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 100mm.
The current version of BS1289 recommends 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

Older editions of BS1289 required a cross-sectional area of 13,000mm2.
.
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.
4.9.4 To a builder’s opening within the dimensions shown in figure 1.
4.9.5 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.
4.10 Suitable flues and minimum flue sizes are as follows: -
• 225mm x 225mm conventional brick flue.
• 175mm diameter lined brick or stone flue.
• 200mm diameter factory made insulated flue manufactured to BS 4543.
• 175mm diameter flue pipe (see B.S 6461 part 1 for suitable materials).
• Single wall, twin wall or flexible flue liner of minimum diameter 125mm. The
materials to be used are stainless steel or aluminium as specified in B.S 715.
• A properly constructed precast concrete or clay flue system conforming to BS1289 or
BS EN 1806.
It should be noted that, sharp bends or horizontal runs in metal flues at the top of the
system could be a cause of problems in these types of installation.
4.10.1 The minimum effective height of the flue must be 3m.
4.10.2 The flue must be completely sealed so that combustion products do not
come into contact with combustible materials outside the chimney.
4.10.3 The flue must serve only one fireplace.
Page 8
INSTALLER’S GUIDE
4.10.4 Proprietary terminals must comply with BS 715 or BS 1289. Any terminal
or termination must be positioned in accordance with BS 5440 Part 1 to ensure that the
products of combustion can be safely dispersed into the outside atmosphere. Where the
appliance is connected to an unlined brick chimney it is generally unnecessary for the
chimney pot to be replaced or for a terminal to be fitted unless the flue has a diameter
smaller than 170mm.
4.11 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
4.12 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 surface of the hearth must be sufficiently flat to enable the bottom of the front
surround, the burner bracket and the bottom front cover casting to be aligned
horizontally. Any excessive unevenness (uneven tiles, Cotswold stone, etc.) should be
rectified.
The appliance must not stand on combustible materials or carpets.
The appliance must not be fitted directly against a combustible wall. If the
appliance is to be fitted against a wall with combustible cladding, the cladding must be
removed from the area covered by the outer surround (See figure 1). We suggest that
the actual surround is used as a template to mark the area for combustible cladding
removal.
4.13 The front face of the fireplace should be reasonably flat over the area covered by
the convection box 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
convection box can be made.
4.14 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.
4.15 Propane gas appliances must not be installed in a room, which is built entirely
below ground level (See BS 5871 Part 2).

6 FIREPLACE CHECK
1. The fireplace must comply
with all the requirements of section
2. The debris catchment area
shown in figure 3 must be kept
clear of obstructions.
3. Fireplace General Condition
The fireplace floor should be
reasonably flat to ensure that the
convection box can be installed
without it rocking and so that a
good seal can be made at the
bottom front of the box. The front
face of the fireplace should be
reasonably flat over the area
covered by the convection box top and side flange seals to ensure good sealing. These
faces should be made good if necessary. If the appliance is to be fitted against a wall with
combustible cladding, the cladding must be removed from the area covered by the outer
surround (see figure 1). We suggest that the actual surround is used as a template to mark
the area for combustible cladding removal.
4. Soundness for appliance attachment
Two primary methods of retaining the appliance are provided: -
1) By fixing to the fireplace front.
2) Using concealed tension cables fixed to the rear of the fireplace opening together
with secondary fixing to the fireplace floor.
The methods are detailed in section 10 of this manual. Before selecting the retention
method, consult with the customer. Method 2 is provided for instances where drilling
holes in the front surface of the fireplace surround is unacceptable to the customer or
otherwise impractical. N.B. It is unwise to attempt to drill into marble without the proper
Figure 3. Fireplace debris catchment minimum
areas.
tools and equipment.
If method 1 is chosen, make sure that the fireplace front surround area is sound enough to
take the rawlplugs and woodscrews. If necessary, make sound with a suitable cement.
If method 2 is chosen, make sure that the areas at the back and towards the centre of the
fireplace floor are sound enough to take the eyebolts and screws. If these areas have
deteriorated due to prolonged use, they should be made sound with a suitable cement.
5. Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a layer of
mineral wool or equivalent insulation at least 100mm thick. See figure 1.
