2. APPLIANCE DATA
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. 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 0595211.
The appliance data label is located on a plate at the base of the fire. This can be seen by
removing the lower front casting.

3.2 In the United
Kingdom, as supplied,
the appliance can be
installed in the following
situations: -
3.2.1 To a fireplace
complete with surround
and hearth as shown in
figure 1 and complying
with BS1251 after
removal of the fireback
and sufficient material
behind the fireback for a
debris catchment space.
The required fireplace,
hearth, debris catchment
area and clearance
dimensions are shown in
figure 1.
3.2.1.1 ‘Hole-in-the-wall’ installations.
! It is recommended that a hearth should be installed as in figure 1.
!
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 100 mm. 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.
3.2.2
To a fireplace incorporating a metal flue box complying with the constructional
requirements of the current edition of BS715. The dimensions of the flue box must
Page 6
INSTALLER GUIDE
Figure 1. Hearth and fireplace opening dimensions

conform to those shown in
figure 2.
3.2.3 To a precast concrete or
clay flue block system
conforming to BS1289 or BS
EN 1806 with dimensions as in
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 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.
! 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 BS715. 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 1806. This system is only suitable if the conditions stated in section 3.2.3 are
met.
Page 7
INSTALLER GUIDE
Figure 2. Metal Flue box dimensions

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 damper or
restrictor should be removed. If
removal is not possible, they
must be secured in the open
position.
3.7 If the appliance is intended
to be installed to a chimney that
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
Page 8
INSTALLER GUIDE
Figure 3.Precast or clay flue block system

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.
3.10
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.
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 shown in 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
This appliance must not be installed in any room that 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
Installations” which makes clear the conditions that must be met to demonstrate that
sufficient ventilation is available.
3.16
Propane gas appliances must not be installed in a room that is built entirely below
ground level (See BS 5871 Part 2).
3.17 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 fasia
(See figure 4). 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.
3.18 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 shown in figure 5.
A 10mm access clearance from a non-combustible surface is necessary at the left side.
(See figure 5).
3.19 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.

Figure 4. Removal of combustible
cladding

3.20 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 manufacturers replacement
part should be fitted. The individual A.S.D components are not replaceable.
3.21
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, or the infirm.

5. FIREPLACE CHECK
5.1 Fireplace check.
5.1.1 Fireplace size
The fireplace must
comply with the
requirements described
in section 3.2. This will
probably entail
removing the fireback
and infill material
behind the fireback. The
debris catchment area
shown in figure 7 must
be kept clear of
obstructions.
5.1.2 Fireplace general
condition
The fireplace floor
should be reasonably
flat to ensure that the
hotbox 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 hotbox 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
fascia. The cladding must also not touch the fascia (See figure 4). 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.
5.1.3 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 equipment.
If method 1 is chosen, make sure that the front surround area is sound enough to take
the fibre plugs and woodscrews. If necessary, make sound with a suitable cement.
Page 14
INSTALLER GUIDE
Figure 7. Fireplace area.

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.
5.1.4 Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a minimum
100mm layer of mineral wool or equivalent insulation (See figure 2).
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.
6. IGNITION CHECK
Before attempting to install, it is worth checking that the ignition system performs
satisfactorily.
Set the control knob to the off position.
Depress the control knob and rotate it anticlockwise to the pilot ignition position. A
'click' will be heard as the integral piezo operates. A spark should be seen between the
electrode and pilot tip. If there is no spark check the following: -
! Ensure that the electrode lead is connected to the terminal at the base of the
electrode.
! If the above is correct, check for damage to the electrode lead.
Page 15
INSTALLER GUIDE
Figure 8. Ignition operation

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. The ‘T’ connector 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 hotbox and run to the ‘T’
connector at the front. The pipe run from the supply line up to the rear opening in the
hotbox must be kept away from the area which will be taken by the hotbox when it is
installed (See figure 7).
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.
8. PREPARING APPLIANCE FOR INSTALLATION
IMPORTANT
Before continuing with the
installation of this gas fire the
aeration setting on the burner
must be checked. The aeration is
factory set, but will require
adjustment. See section 17.1
(Servicing and parts
replacement).
1. Detach the burner unit from the
hotbox by removing two screws (See figure 9). Lift the burner unit clear.
2. Fit the two “U” section seals to the bottom edges of the hotbox side flanges (See
figure 10).
3.
It is important that the grommet supplied in the loose parts pack is fitted to the
hole in the rear of the hotbox.
For concealed connection only:
4.
Pierce the grommet to allow the pipe to pass through it. The grommet should envelop
the pipe. If the hole is larger than the pipe, seal it with tape. Do not pierce the
grommet unless the supply pipe is to pass through it.
Page 16
INSTALLER GUIDE
Figure 9. Burner attachment points

5. The appliance is supplied with two fireback spacers. Do
not fit the fireback spacers if the fire is to be installed into a
precast or clay flue block system as in section 3.2.3. These
should extend backwards to ensure sufficient clearance from
the back of the fireplace. Remove the label and retaining
screws from the rear sides of the hotbox. Position the
fireback spacer as shown in figure 11. Secure the fireback
spacers using the screws removed previously and the two
supplied with the fire.
6. This appliance is supplied with a flue restrictor for use
where the flue draught is excessive. The restrictor must NOT
be fitted where a precast flue or a flue liner is used. For all
other installations the restrictor should be fitted. There may
however, be certain exceptional circumstances where
fitting the restrictor causes the fire to fail the spillage
test. In such cases the restrictor will have to be
removed. After removal conduct the spillage check
again.
The restrictor is packed loose with the appliance and is
fixed with two screws (See figure 12).
Page 17
INSTALLER GUIDE
Figure 12.Flue restrictor
Figure 11. Fireback spacers
Figure 10. ‘U’ seals

7. There is a length of self adhesive foam
seal supplied with the fire. This will need
to be fitted to the outer rear edges of the
side and top flanges of the hotbox. Cut a
485mm length of foam seal. Be careful not
to stretch the seal when measuring.
Remove the protective backing from the
foam seal and fit this to the rear of the top
flange (See figure 13). Cut two 580mm
lengths. Fit these to the rear outer edges of
the side flanges. Ensure that there is no
gap between the foam seals where they
meet at the top flange (See figure 13).
8. This appliance is supplied with a rear
ceramic support bracket. Fit this using two
screws supplied (See figure 14)
9. HOTBOX INSTALLATION
9.1 Method 1 - Front fixing to fireplace surround.
1. Make sure that the fireplace front surround area is sound enough to take the fibre
plugs and woodscrews. If necessary, make sound with a suitable cement.
2. Place the hotbox centrally in the fireplace in the position in which it is to be
permanently installed. If a concealed connection is being used, insert the hotbox into the
fireplace feeding the supply pipe through the pierced hole in the rear grommet.
3.
Mark the fireplace front surround through the four fixing holes in the side flanges of
Page 18
INSTALLER GUIDE
Figure 14. Fitting the rear ceramic support.
Figure 13. Fitting the foam seal

the hotbox (See figure 15).
4. Remove the hotbox. Drill four holes in the
fireplace front surround at the marked
positions using a no.12 masonry drill.
5. Insert a fibre plug into each hole.
6. Place the hotbox back in position in the
fireplace.
7. Fit a woodscrew through each hole in the
hotbox flanges and tighten to seal the box to
the fireplace surround.
9.2 Method 2 - Cable retention and floor
fixing.
1. Make sure that the relevant
areas at the fireplace back or
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.
2. Drill four holes in the rear
wall of the fireplace for the
eyebolt plugs. The holes should
be drilled within the range of
positions shown in figure 16
using a no.12 masonry drill.
The holes should be equidistant
each side of the centre line of
the fireplace to ensure that the
appliance finishes centrally in
the opening when tension is
applied to the cables.
3. Insert a fibre plug into each
hole. Use the fibre plugs
supplied with this appliance -
Never use plastic plugs
instead of the fibre plugs
supplied. Screw the eyebolts into the plugs. Make sure that the bolts are secure.
4. Place the hotbox unit close to the fireplace but allow sufficient access into the
fireplace opening so that the cables can be threaded through the eyebolts and returned
Page 19
INSTALLER GUIDE
Figure 16. Eyebolt positions
Figure 15. Front fixing

through the back of the hotbox. If a concealed
connection is being used, insert the hotbox into
the fireplace feeding the supply pipe through
the pierced hole in the rear grommet.
5. The hotbox has two holes at each side of the
spillage plate. Insert one end of each cable (one
cable each side) from the back through the
lower of the two holes and return the end
through the upper of the holes (See figure 17).
Give the cables a pull so that they grip against
the hotbox flanges.
6. Thread the cables through the eyebolts.
Return the cables through the holes near the
bottom of the hotbox back panel (See figure 18) (For
precast or clay block flue systems return the cables
through the slotted holes in the side of the hotbox).
7. Place the hotbox fully back into the fireplace opening
so that it is sealed against the fireplace front surround.
8. Drill a hole into the fireplace floor through each of
the two holes in the base of the hotbox using a no.12
masonry drill (See figure 19).
9. Insert a fibre plug into each hole. Use the fibre plugs
supplied with this appliance - Never use plastic plugs
instead of the fibre plugs supplied.Fit a
woodscrew in each plug and tighten.
Always screw the base into position before
applying tension to the cables. This will ensure a
tight seal between the top of the hotbox and wall
10. Fit a cable retainer over the bottom end of each
cable.
11. Pull each cable taut. Push the cable retainers
hard up against the back panel. The end of the
cable adjuster will pass into the hole. Tighten the
screws in the retainers so that they clamp the
cables in position. Apply tension to the cables by
turning the hexagonal adjusters by hand (See figure
20).
12. Inspect the installation of the hotbox against the
