1 APPLIANCE DATA
This product uses fuel effect pieces, burner compartment walls 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 located on a ‘pivot’ plate at the base of the fire. This can be
seen be pulling on the raised tab.

2 GENERAL INSTALLATION
REQUIREMENTS
2.1 The installation must be in accordance with these instructions.
For the user’s protection, in the United Kingdom it is the law that all gas appliances are
installed by competent persons in accordance with the current edition of the Gas Safety
(Installation and Use) Regulations. Failure to install the appliance correctly could lead to
prosecution. The Council for the Registration of Gas Installers (CORGI) requires its
members to work to recognised standards.
In the United Kingdom the installation must also be in accordance with:
All the relevant parts of local regulations.
All relevant codes of practice.
The relevant parts of the current editions of the following British Standards: -
BS 715
BS 1251
BS 1289 Part 1
BS 1289 Part 2
BS EN 1806
BS 4543 Part 2
BS 5440 Part 1

the Environment for
Northern Ireland.
In the republic of Ireland
the installation must also
conform to the relevant
parts of:
a) The current edition of
IS 813
b) All relevant national
and local rules in force.
2.2 In the United
Kingdom, as supplied, the
appliance can be installed in
the following situations: -
2.2.1 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.
2.2.1.1 ‘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 85mm. 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.
2.2.2 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
conform to those shown in figure 2.
A precast concrete or clay flue block system conforming to BS1289 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
Figure 2. Metal Flue box dimensions

INSTALLER’S GUIDE
Page 7
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.
2.2.3 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.
2.4 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
Figure 3. Precast or clay flue block system

INSTALLER’S GUIDE
Page 8
BS EN 1806. This system is only suitable if the conditions stated in section 2.2.2 are met.
2.5 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.
2.6 The flue must not be used for any other appliance or application.
2.7 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
2.8 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.
2.9 If the fireplace opening is an underfloor draught type, it must be sealed to stop any
draughts.
2.10 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 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.
2.11 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.

INSTALLER’S GUIDE
Page 9
Graph 1. Combustible shelf clearances
2.12 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.
2.13 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.
2.14 This appliance must not be installed in any room that contains a bath or shower or
where steam is regularly present.
2.15 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.
2.16 In the United Kingdom (GB) no special ventilation bricks or vents are normally
required in the room for this appliance. In the Republic of Ireland (IE) permanent
ventilation must comply with the regulations currently in force.

INSTALLER’S GUIDE
Page 10
2.17 Propane gas appliances must not be installed in a room that is built entirely below
ground level (See BS 5871 Part 2).
2.18 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. For access to the Fireslide control and to maintain a
2mm gap around the outer case a maximum cladding depth of 6mm is recommended
(See figure 4).
Figure 4. Removal of combustible cladding

INSTALLER’S GUIDE
Page 11
2.19 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.
2.20 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.
Dimension X is 50mm. This can be deleted when installing into a pre-cast or clay flue
block system.

4 FIREPLACE CHECK
4.1
4.1.1 Fireplace size
The fireplace must comply
with the requirements
described in section 2.2.
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.
4.1.2 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. 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. For access to the Fireslide control
and to maintain a 2mm gap around the outer case a maximum cladding depth of 6mm is
recommended (See figure 4).
4.1.3 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 8 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

INSTALLER’S GUIDE
Page 15
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
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.
4.1.3 Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a 100mm layer
of mineral wool or equivalent insulation. (See figure 2).
4.2 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 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 8). The positive
terminal (+) is to the bottom as you
insert.
Rotate the control pivot bracket as far
as it will go. This should close the
ignition circuit. Sparks should be seen
tracking from the electrode pin to the
thermocouple tip. See figure 9.
●If there are no sparks make the following
checks.
a. Check condition of battery and that it is
correctly fitted.
b. Check spark gap between electrode
wire and thermocouple tip. See figure
10.
c. If a & b are satisfactory, check the
ignition circuit and components - see
the servicing section in this
manual.

INSTALLER’S GUIDE

6 GAS SUPPLY CONNECTION
A nut and olive are provided for an 8mm pipe inlet connection to the elbow at the bottom
front of the appliance. The elbow can be rotated to allow a connection from any
direction. The elbow includes a valve for isolating the gas supply.
The supply pipe must be rigid material. Flexible pipe must not be used.
6.1 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 chosen removable circular panel at the back of the
convection box and run to the elbow 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 7).
Note that the centre of the appliance inlet elbow is 25mm above the fireplace floor. The
inlet elbow should be removed from the appliance and fitted to the supply pipe at this
stage.

7 PREPARING APPLIANCE FOR
INSTALLATION
IMPORTANT
Before continuing with the installation
of this gas fire the aeration setting on
the burner must be checked. This has
been factory set. See section 16
(Servicing and parts replacement).
1. Detach the burner unit from the
convection box by removing two screws -
See figure 11. Lift the burner unit clear.
2. Fit the two “U” section seals to the bottom
edges of the convection box side flanges. See figure
12.
3. For concealed connection only: There are two
removable circular panels at the rear of the
convection box. Decide which one of these is to be
used for rear entry. Using a suitable tool apply
pressure to the centre of the removable circular
panel. There is a grommet in the installation kit
supplied with the fire. Fit this into the hole.
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.
4. 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
2.2.2.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 convection
box. Position the fireback spacer as shown in

INSTALLER’S GUIDE
Page 19
figure 13. Secure the fireback spacers
using the screws removed previously
and the two supplied with the fire.
5. 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 three screws. See figure 14.
6. 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 convection
box. 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 15). 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 15)

brackets at left and right sides (See figure 16)
8 CONVECTION BOX INSTALLATION
8.1 Method 1 - Front Fixing to Fireplace Surround
1. 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.
2. Place the convection box centrally in the
fireplace in the position in which it is to be
permanently installed. If a concealed
connection is being used, insert the
convection box into the fireplace feeding the
supply pipe through the pierced hole in the
rear seal.
3. Mark the fireplace front surround through
the four fixing holes in the side flanges of the
convection box. See figure 17.
4. Remove the convection box. Drill four
holes in the fireplace front surround at the
marked positions using a no.12 masonry drill.
5. Insert a rawlplug into each hole.
6. Place the convection box back in position in the fireplace.
7. Fit a woodscrew through each hole in the convection box flanges and tighten to seal the
box to the fireplace surround.
