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. Page 4

3.1.2
Electrical isolation of the unit should be by means of a switched 3A fuse spur that
should be readily accessible to the user, easily identifiable and sited within reach of the
mains cable provided. It should only connect this appliance.
3.1.3 This fire is a fan flued appliance for installation on an outward facing wall of a
conventional home which does not have a purpose built flue or chimney.
3.1.4
As supplied, the appliance is suitable for homes constructed of brick, stone, etc.,
the appliance can be installed into walls up to a maximum thickness as shown below.
If the fire box is in front of the finished wall surface: 600mm (23 5/8in) max.
These dimensions are from the finished internal wall surface (including any surround
material) to the external wall surface.
3.1.5
Installation to a timber framed building should be in accordance with the relevant
sections of Institute of Gas Engineers publication IGE/UP/7 “Gas installations in timber
frame buildings”. Please note that advice should be sought before installing in a
timber frame building since the alterations required may nullify any NHBC cover
relating to the property. If in doubt, guidance should be requested from your local
authority planning or building department.
This appliance must be mounted with a non-combustible hearth (See figure 1) (N.B.
conglomerate marble hearths are considered as non-combustible). The fire box must be
mounted on a non-combustible surface level with the hearth. The hearth must project at
least 300mm forward of the fire box front and be at least 625mm wide (see illustrations
in “wall preparation” section). 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
casting to be aligned horizontally. Any excessive unevenness (uneven tiles, Cotswold
Page 6
INSTALLER GUIDE

stone, etc.) should be rectified.
3.1.6 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 or skirting board, such
materials must be removed from the area covered by the fascia of the appliance. We
suggest that the fascia is used as a template to mark the area for combustible cladding
removal.
The appliance can be fitted to a purpose made proprietary class “O” 150°C surround.
The opening in the surround or wall recess for the fire box must be within the limits
shown in figure 1.
3.1.7. ‘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 88
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. The minimum
shelf height will have to be taken from the base of the fireplace opening.
3.1.8 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 = 700mm.
!For a shelf deeper than 150mm: 700mm + 12.5mm for every 25mm depth over
Page 7
INSTALLER GUIDE
Figure 1. Hearth and recess requirements

150mm (See Graph 1).
3.1.9 The front face of the wall should be reasonably flat over the area that will be
covered by the fire box top and side flanges to ensure a good seal. The minimum height
from the top surface of the hearth to the underside of any shelf made from wood or
other combustible materials is as follows:-
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.
3.1.10
The appliance must not be installed in any room that contains a bath or shower or
where steam is regularly present.
3.1.11
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, or provision is made to ensure that
the fan and the appliance cannot be used at the same time.
A fan-powered flue system tends to depressurise the room containing the appliance.
3.1.12 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, however the spillage check (See further on in this
Page 8
INSTALLER GUIDE
Graph 1.

guide) may indicate a need for further ventilation in order to ensure that there is
adequate air replacement. If necessary seek expert advice.
3.1.13 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.
3.1.14
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, or the infirm.
3.1.15 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 a 50mm clearance is recommended from non-combustible surfaces.
3.1.16
A concealed gas supply connection can be made through the rear panel. Visible
front connection can be from the left or right side after an opening has been cut in the
appropriate side of the hearth casting.
Electrical connection is from the right side.
3.2 Flue Siting
3.2.1 The flue terminal should be located so that
the wind can blow freely across it at all times and
where any blockage due to leaves, snow, etc. is
unlikely. The minimum allowable distances from
the terminal are shown in figure 3.
Note: The distances are from the edge of the
vertical exit slots in the terminal not from the
edges of the rectangular box (See figure 2).
3.2.2 This appliance is supplied with a terminal
guard. In England and Wales, the Building
Regulations require that the terminal guard is fitted
if the flue terminal can come in contact with
people near the building or be subject to damage.
Even if the regulations do not demand it, we
recommend that the guard is fitted to prevent
damage or blockage of the flue system by leaves etc.

6. PREPARING FOR INSTALLATION
Check ignition spark.
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 (See figure 6).
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.
In the majority of cases, the burner
unit will need to be detached. Detach
the burner unit from the convection
box by removing two screws (See
figure 7). Carefully lift the burner unit
out from the hotbox and place
immediately in front of the hotbox. Do
not attempt to lift the burner module
away from the front of the firebox as
this may damage the solenoid leads.
Disconnect the solenoid leads from the
control box.
7. WALL PREPARATION
7.1 General.
1.
Make sure that the installation will comply with all the relevant requirements in part
3 of this manual.
2. Attempt to keep the hole sizes as close to the minimum dimensions as possible in
order to minimise the sealing required.
3.
Make sure that the damp course or any electrical wiring, piping etc. in the wall is not
affected when cutting the installation hole.
4. Any gas supply pipe installed in the wall, floor or cavity of a cavity wall must be
continuous and enclosed in a factory fitted gas tight sleeve (Ref: Gas safety (Installation
& Use) Regulations 1994 as amended & Certificate of exemption no.1 1996)
Page 16
INSTALLER GUIDE
Figure 6. Pilot ignition
system.
Figure 7. Burner unit removal.

7.2 Brick, stone etc. building. Main case in front of wall (Figure 8).
1. This installation is for use with a fire surround
or false chimney breast having a minimum depth
of 140mm (5 1/2in.). The flue length may be cut
to suit the wall thickness. (See prepare flue
assembly section) Combustible material within a
false chimney breast must be at least 75mm from
the fire box.
2. The non-combustible hearth must project at
least 300mm in front of the convection box front
flanges and be at least 625mm wide (Figures 1 &
8).
3. The cavity should be sealed where the flue tube
hole has been cut. We recommend filling fully
across the cavity with Rockwool or equivalent to
at least 100mm around the opening (See figure 12)
7.3 Brick, stone etc. building. Main case
recessed into wall.
(Figure 9)
1. This installation has the fire box recessed into
the inner wall of the building. The front flanges
of the fire box and the appliance fascia will abut
the front surface of the wall.
2. The non-combustible hearth must project at
least 300mm in front of the convection box
front flanges and be at least 625mm wide
(Figure 1).
The recess in the inner wall for the fire box
should be to the size shown in figure 1. The
bottom of this recess should be at the same level
as the top surface of the hearth.
A lintel may be required above the recess for the
fire box. If in doubt, seek expert building advice
before commencing to cut the recess.
Whenever a lintel is required to support the
recess in the inner leaf of a brick/blockwork building, refer to the following section (See
figures 10 and 11).
Page 17
INSTALLER GUIDE
Figure 9. Main case recessed into
wall.
Figure 8. Main case in front of
wall.

Page 18
INSTALLER GUIDE
7.4 Lintel installation.
1.The lintel should be either steel (Catnic) or
reinforced precast concrete. It should be 750mm
long x 75mm deep x inner leaf thickness.
2. The opening should be, as near as possible,
centrally below a joint in the inner leaf block.
3. Cut out the opening for the lintel.
Where cutting through masonry, drill pilot holes
and then cut out the slot using a mechanical cutter.
This will minimise damage to the surrounding
structure.
4. Insert the lintel. Bed the lintel on mortar.
Don’t dry bed. Slate pin to ensure the lintel and
structure above is secure and safe
5. Make the opening below the lintel by
removing the masonry and clearing debris. If
the cavity has loose fill (e.g. granular)
insulation material, pack the edges of the
opening with Rockwool as you proceed to hold
back the insulating material.
6. The wall cavity must not be bridged other
than by the flue tube assembly. The fire box
must not project into the cavity
between the inner and outer walls by
more than 10mm.
See wall preparation for flue
tube.
The cavity should be sealed where the
opening has been cut. We recommend
filling fully across the cavity with
Rockwool or equivalent to at least
100mm all around the flue tube. Fill at
the bottom of the opening to the level
of the hearth/fireplace floor. It may be
simplest to back fill the cavity with
the insulation material and then cut
through the insulation to the size of
the flue box hole. Figure 12. Flue pipe insulation
Figure 11.
Figure 10.

7.5 Timber frame building. Firebox in front of wall.
This installation is for use in timber framed buildings in conjunction with a fire
surround having a minimum depth of 153mm (6 inch).
1.
The non-combustible hearth must project at least 300mm in front of the convection
box flanges and be at least 625mm wide. For this type of installation the hearth must be
at least 50mm thick over its total area (Figure 1). Installation must be in accordance
with the current edition of Institute of Gas Engineers publication IGE/UP/7.
2.
The back surface of the firebox and flue tube assembly must be separated from the
timber frame by 25mm of non-combustible material. This can consist of the usual
13mm plasterboard wall lining plus 12mm of “Superlux” or similar non-combustible
material. The opening should be between studs.
7.6 Wall preparation for flue tube.
1.
The flue must be installed so that it is at right angles to the back panel of the fire all
round the flue circumference. The fire itself should be fitted vertically against a flat
wall. Where this is difficult to achieve due to building inaccuracies care should be
taken to ensure that the back of the fire is not stressed in any way due to distortion of
the assembly when tightening the fixing screws. Where necessary, non-combustible
packing pieces should be used to provide a satisfactory fixing surface.
2.
Before cutting the hole in the wall make sure that the height to the top surface of the
finished floor is known. The height from this surface to the flue hole centre is shown in
figure 14.
3.
If a loose hearth or plinth is to be used, the height from its top surface must be used
when determining the flue height.
4. Place dust sheets on the floor and over any furnishings etc.
5. Make sure that the centre of the flue hole is as shown in figure 14.
6. Cut the hole for the flue unit.
7.7 Core drilling.
1. Drill a pilot hole through the wall. Inspect the hole to ensure that it is in the
brickwork and not in mortar. If it is in mortar, it is advisable to reposition the hole
approximately 25mm away (Ensuring that all other clearances to firebox are complied
with). Remember to reposition the screw fixing holes.
2. Drill the flue hole with a 5in. (127mm) core drill.
3.
Remove any combustible wall cladding material from the area behind the firebox as
described previously.
7.8 Hammer and chisel cutting.
1.
Mark a 127mm (5in) diameter circle for the flue hole. Chisel out the area marked.
It may be necessary to make good both the internal and external wall faces. To achieve
a neat finish and to make any future removal of the flue unit easier, it is recommended
Page 19
INSTALLER GUIDE

that a cardboard cylinder is formed around the flue unit and inserted in the hole whilst
making good. Remove the cardboard cylinder after making good.
7.9 Combustible walls (wood, fibreboard, plasterboard etc.).
1.
Building regulations require that the outer surface of the flue tube and terminal must
not be closer than 25mm to combustible material and must be lined with steel sleeve not
less than 0.5mm thick (See figure 13). The sleeve can be made by coiling a piece of
sheet steel to between 125mm & 127mm outside dia. and fitting it to the combustible
parts of the construction.
2. Mark out and cut a hole
177mm diameter through the
plasterboard.
3. Cut a hole of about 165mm
in the vapour barrier. Clear the
insulation quilt from the hole
area and cut a 177mm dia.
hole in the timber sheathing
and breather paper.
4. Drill a 127mm diameter
hole through a non-
combustible (brick etc.) outer
wall.
5. Fit the steel sleeve. The
sleeve should not protrude
more than 10mm into the
cavity. The sleeve should be
sealed to the inner leaf of the
wall at both ends with a non-
setting thermal mastic sealant.
6.
If the outer wall is combustible drill a 177mm hole and fit the liner sleeve through to
this wall.
7. Cover the hole with a steel plate size 500mm (Vertical) x 235mm, not less than
1.5mm thick with a 127mm diameter hole in the middle. Fix with suitable screws and
plugs.
8.
Where the whole wall is of combustible material a non-corrosive plate 455mm square
with a 127mm diameter hole in the centre must be fitted to the outer face of the wall.
9. The area immediately behind the firebox must be separated from the combustible
elements of the inner wall by 25mm thickness of non combustible material.
This can consist of the usual 13mm plasterboard wall lining plus 12mm of “Superlux”
or similar non-combustible material (See figure 13).
