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 / firefront and casting.

INSTALLER GUIDE
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.
Page 8
INSTALLER GUIDE
Figure 3. Pre-cast Fireplace

3.3.4 The flue must serve only one 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.
Page 9
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
Installations” which makes clear the conditions that must be met to demonstrate that
sufficient ventilation is available
Page 10
INSTALLER GUIDE
Graph 1. Combustible shelf clearances

3.16 Propane gas appliances must not be installed in a room, which is built entirely
below ground level (See BS 5871 Pt2).
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 outer surround. The cladding
must also not touch the surround. (See figure 4).
We suggest that the actual surround 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 both sides.
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.
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 may
entail removing the fireback and infill material behind the fireback.
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 outer surround.
The cladding must also not touch the surround. (See figure 4). We suggest that the
actual surround 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
One primary methods of retaining the appliance is provided: -
1) Using concealed tension cables fixed to the rear of the fireplace opening.
The method is detailed in section 9.1 of this manual. Make sure that the areas at the
back and towards the centre of the fireplace floor are sound enough to take the eyebolts.
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
50mm 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.
Page 14
INSTALLER GUIDE

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.
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. 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
8.1 Appliance Preparation
1. Remove any transit tape and
packing and inspect for any evidence
of mishandling which might affect the
performance. Each unit is flame
tested before it leaves the factory and
as a result there may be slight
discolouration around the burner
ports.
2. Detach the burner unit from the
hotbox by removing two screws - See
figure 8. Lift the burner unit clear.
IMPORTANT
Before continuing with the installation
of this gas fire the aeration setting on
the burner must be checked. The
aeration is factory set for use with a
ceramic pebble fuel effect. See section
17.1 (Servicing and parts
replacement).
3. It is important that the grommet
supplied in the loose parts pack is fitted
to the hole in the rear of the hotbox.
8.2 Fitting the Front Surround - For models supplied with a three section front
surround
1. The front surround is supplied in three sections. Remove any protective film. The two
longer sections are the left and right sides. The shorter section is the top. The left and
right hand sections have folded edges, one of which is shorter than the other. This
shortened edge should be fitted at the inner top on both sides. Fit the top section last and
centralise (See figure 9)
8.3 Fitting the Front Surround - For models supplied with a one piece front
surround.
Page 16
INSTALLER GUIDE
Figure 9. Fitting the front surround
Figure 8. Burner attachment points

1. The front surround will already be fitted.
Remove any protective film.
8.4 Fitting the foam seal.
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. This will be fitted over
the flanges of the front surround. It is therefore
important to ensure that the front surround
is positioned correctly before fitting the foam
seal. Cut the foam seal to the required length.
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
hotbox flange (See figure 10).
8.5 The Flue Restrictor
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 125mm flue liner is used.
For flue liners greater than 125mm and 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 flat with the appliance and
will require bending prior to fixing. Bend the
restrictor as shown in figure 11.
Fit the restrictor as shown in figure 12 using the two
screws provided.

INSTALLER GUIDE
9. FIREBOX INSTALLATION
9.1 Firebox Installation
1. Make sure that the relevant
areas at the fireplace back are
sound enough to take the
eyebolts. 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 13 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 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 rear of the hotbox has a slot and hole each side of
the outlet opening. Assemble one end of the cable to the
top of the fire by passing it through the small round hole
and locking by positioning the cable in the adjacent slot.
See figure 14. Give the cables a pull so that they grip.
6. Thread the cables through the eyebolts. Return the
cables through the holes near the bottom of the hotbox
side panels - See figure 15 Figure 15. Cable Route
Figure 14. Upper cable retention
Figure 13. Eyebolt Positions

7. Place the hotbox fully back into the
fireplace opening so that it is sealed
against the fireplace front surround.
8. Fit a cable retainer over the bottom
end of each cable.
9. 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 16.
10. Inspect the installation of the
hotbox against the fireplace surround.
If the hotbox is aligned squarely and
the sealing is satisfactory, fully tighten
the cable retainers.
11. If the hotbox is not correctly
aligned, release the tension on the
cables by slackening the screws and
turning the hexagonal adjusters fully
anticlockwise. The hotbox should then
automatically realign itself. Pull each
cable taut again and push the cable
retainers back against the back panel.
Again, tighten the screws in the retainers and apply
tension to the cables by turning the hexagonal
adjusters clockwise as far as possible.
12. Do not cut off any excess cable, instead coil up
the cable so that they are available to allow easy
removal and refitting of the appliance during
subsequent service calls.
9.2 Floor Sealing (All Installations)
Using the floor sealing tape supplied, seal the
bottom of the hotbox to the fireplace and hearth
floor. Run the tape over the centre bracket.

the firefront surround.
1. Depress the control knob and rotate it slowlyanticlockwise 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.
2. Turn the control knob clockwise to the 'Off' position. Repeat this operation until a
flame appears at the pilot. There may be a delay before the pilot lights due to air being
purged from the system. When a flame appears at the pilot keep the control knob
depressed and hold the pilot ignition position for five seconds. When the control knob is
released the pilot flame should remain lit.
10.2.2 Operating the burner.
1. When the pilot burner is operating properly, gradually turn the control knob anti-
clockwise to 'HIGH' (Depress the knob slightly to get past the pilot ignition position).
The main burner should now light. Depress the control knob slightly to release from the
'HIGH' position and turn back (clockwise) to 'LOW'. While turning, the burner flames
should gradually become lower but remain alight. Depress the control knob slightly to
release from the 'LOW' position and turn back (clockwise) to the Pilot ignition position.
The main burner should extinguish but the pilot should remain alight. Depress the
control knob slightly and turn back (clockwise) to turn OFF.
This will extinguish the pilot.
If the above checks are satisfactory, continue with the installation. If not, check the
control and ignition circuitry and components.
