This product uses fuel effect pieces and burner compartment walls 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. RCF waste is classed
as a stable, non-reactive hazardous waste and may be disposed at a landfill licensed to
accept such 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.

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
Installations” which makes clear the conditions that must be met to demonstrate that
sufficient ventilation is available.
3.3 The Atmosphere sensing device (ASD).
The appliance is fitted with an A.S.D (Atmosphere sensing device). If the appliance
closes down after a period of operation for no apparent reason, the consumer should
be informed to stop using the appliance until the installation and appliance have been
thoroughly checked. The A.S.D will shut the appliance down if an unacceptable
amount of harmful products of combustion accumulate. Under no circumstances
should the A.S.D be altered or bypassed in any way. Only a genuine manufacturer’s
replacement part should be fitted. The individual A.S.D components are not
replaceable.
3.4 Fireguard requirements.
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, the infirm and pet animals.
3.5 Room considerations.
3.5.1 This appliance must not be installed in any room that contains a bath or shower
or where steam is regularly present.
3.5.2 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.
3.5.3 Note that soft wall coverings (e.g. embossed vinyl, etc.) are easily affected by

INSTALLER GUIDE
3.6.2 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
3.7 Fireplace preparation.
3.7.1 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
3.7.2 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.
3.7.3 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.
3.7.4 If the appliance is to be fitted against a wall
with combustible cladding, the cladding must be
removed from the area covered by the fascia. The
cladding must also not touch the fascia (See figure
1). We suggest that the actual fascia is used as a
template to mark the area for combustible cladding
removal and that this area is increased by at least
2mm all round.
3.7.5 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.
3.8 The hearth.
The appliance must be mounted behind a non-combustible hearth unless the
conditions of section 3.10.1.1 are met (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 and the bottom front cover 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.

3.9 Fireplace clearances.
3.9.1 The minimum height from the base of the fireplace opening 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 = 700mm.
• For a shelf deeper than 150mm: 700mm + 12.5mm for every 25mm depth over
150mm (See Figure 2).
3.9.2 The minimum allowable distance from the outside of the appliance fascia to a
corner wall having combustible material or any other combustible surface which
projects beyond the front of the appliance is 100mm.
For access purposes a10mm clearance from to non-combustible surfaces is
recommended on the left side of the appliance. On the right side the recommended
clearance is 50mm for access to the slider control.

INS ALLER GUIDE
13

INSTALLER GUIDE
3.10.1.1 ‘Hole-in-the-wall’ Installations.
-It is recommended that a hearth should be installed as in section 3.8.
-If a reduced depth hearth is 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 100mm. It is recommended that the reduced hearth has a depth from the
fixing plane of the fire of 100mm minimum. This is necessary to support the lower
front casting. Where there is no floor covering or carpet and the floor is of a type
that is likely to be covered in such a way in the future then the distance from the
base of the fireplace opening in the wall to the floor level should be increased to at
least 175mm.
3.10.2 etal flue box and hearth.
The appliance can be installed to a fireplace incorporating a metal flue box complying
with the constructional requirements of the current edition of BS 715 and with a flue
conforming to BS EN 1856 part 1. The dimensions of the flue box must conform to
those shown in figure 6.
The top, sides and rear surface of the metal flue box must be covered with a 50mm
layer of mineral wool or equivalent insulation (See figure 6).
Important Note: Where the flue box has a base sheet that is single wall (i.e. a single
metal sheet) the flue box must be mounted on a non-combustible hearth. The hearth
material must be at least 12mm thick.
Figure 6. Metal flue box dimensions
INS ALLER GUIDE

INSTALLER GUIDE
3.10.3 Precast concrete or clay flue block system and hearth.
The appliance can be installed to a
precast concrete or clay flue block
system conforming to BS EN 1858
with dimensions as in figure 7.
BS 1289 part 1 recommends 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.
3.11 Flues.
1. Suitable flues and minimum flue
sizes are as follows:
It should be noted that, as with
many appliances, sharp bends or
horizontal runs in metal flues at the
top of the system can be a cause
of problems in these types of
installation.
- 225mm x 225mm conventional brick flue.
- 175mm diameter lined brick or stone flue.
- 200mm diameter factory made insulated flue manufactured to BS4543 Part 2.
- 175mm diameter flue pipe. See BS6461 Part 1 for suitable materials.
- Single wall, twin wall or flexible flue liner with a minimum diameter of 125mm. The
materials to be used are stainless steel or aluminium as specified in
BS EN 1856 Part 1. 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 concrete or clay flue system conforming to BS1289
or BS EN 1858. This system is only suitable if the conditions stated in section 3.10.3
are met.
Figure 7. Precast or clay flue block system
INS ALLER GUIDE

INSTALLER GUIDE
2. 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. The flue must not be used for any other appliance or application.
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.

5. FIREPLACE CHECK
5.1 Soundness for appliance attachment.
Two primary methods of retaining the appliance are provided: -
1) By fixing to the fireplace front surround.
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 9 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 tools and e uipment.
If method 1 is chosen, make sure that the front surround area is sound enough to take
the fibre / wooden plugs and woodscrews. If necessary, make sound with 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 suitable
cement.
5.2 Fireplace flue pull.
Close all doors and windows in the room in which the appliance is to be installed.
After confirming with a match that smoke is drawn into the flue, light a 13 gram smoke
pellet and check that there is a definite flow through the flue. Verify outside that the
smoke exits from one terminal only and that the termination is suitable. Observe,
where possible, upstairs rooms and loft spaces for signs of escaping smoke indicating
a defective flue. If there is not a definite flow warm the flue for a few minutes and
repeat the smoke pellet test. If there is still no definite flow the flue may need remedial
work – Do not fit the appliance until there is a definite flow through the flue.
5. FIREPLACE CHECK
INS ALLER GUIDE

INSTALLER GUIDE
6. IGNITION CHECK
Before attempting to install, it is worth checking that
the electronic ignition system performs satisfactorily.
Fit the battery to the ignition block located below the
burner tray at the left side (See figure 9). The positive
terminal (+) is to the bottom as you insert.
Depress the slider knob as far as it will go and hold in
this position. This should close the ignition circuit and
sparks should be seen tracking from the electrode pin
to the pilot tip (See figure 10).
If there are no sparks make the following checks.
- Check condition of battery and that it is correctly
fitted.
- If the above is satisfactory, check the ignition circuit
and components - see the servicing section in this
guide.
7. GAS SUPPLY CONNECTION
A nut and olive are provided for an 8mm pipe inlet connection to the ‘T’ connector at
the bottom front of the appliance. The ‘T’ connector can be rotated to allow a
connection from any direction and includes a valve for isolating the gas supply and a
pressure test point.
The supply pipe must be rigid material. Flexible pipe must not be used.
Concealed Supply Pipe Connection
If a concealed connection from inside the fireplace is required then, before the
appliance is fitted into the fireplace it will be necessary to extend the supply line so
that it will project through the hole in the back of the convection box and run to the ‘T’
connector at the front. The pipe run from the supply line up to the rear opening in the
convection box must be kept away from the area which will be taken by the
convection box when it is installed (See figure 5).
Note that the centre of the appliance inlet ‘T’ connector is 25mm above the fireplace
floor. The inlet ‘T’ connector should be fitted to the supply pipe at this stage.
