1 APPLIANCE DATA
This product uses a burner compartment rear wall and gaskets containing Refractory
Ceramic Fibres (RCF), which are man-made vitreous silicate fibres. Excessive exposure
to these materials may cause temporary irritation to eyes, skin and respiratory tract.
Consequently, it makes sense 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 on a plate on a tie below the burner and visible when the
bottom front cover is removed.

INSTALLER’S GUIDE
Page 6
2.2 Note that soft wall coverings (e.g. embossed vinyl etc.) are easily affected by
heat. They may therefore, scorch or become discoloured when close to a heating
appliance. Please bear this in mind when installing.
2.3 Installation to a timber-framed building should be in accordance with the
relevant sections of The 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.
Under no circumstances is the fire to be recessed into Timber frame constructions.
For timber framed installations see section 5.
2.4 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.
The current edition of the Building Regulations issued by the Department of the
Environment and the Welsh Office, the Building Standards (Scotland) (Consolidation)
Regulations issued by the Scottish Development Department or the Building
Regulations (Northern Ireland) issued by the Department of the Environment for
Northern Ireland.
All relevant codes of practice.
The relevant parts of the current editions of the following British Standards:-
BS 5440 Part 1
BS 5871 Part 1
BS 6891
In the republic of Ireland the installation must also conform to:
a) The relevant parts of the current edition of IS 813
b) All applicable national and local rules in force.
2.5 A minimum clearance of 51mm should be maintained at each side of the fire for
servicing access.
Any combustible side wall or other combustible projection must be at least 102mm
clear from direct exposure to the radiant surface of the appliance unless suitably
protected.

INSTALLER’S GUIDE
Page 7
2.6 The minimum height from the top surface of the hearth or finished floor to the
underside of any shelf made from wood or other combustible materials is as follows:-
•For a shelf up to 150mm deep
Minimum height = 780mm.
•For a shelf deeper than 150mm
780mm + 12.5mm for every 25mm depth over 150mm.
There is no restriction on the position or depth of non-combustible projections for all
normal installations. Installation into an unusually tightly restricted recess, however,
could cause the temperature of the appliance surfaces to become unacceptably high.
2.7 It is advisable that combustible fabrics such as curtains are not fitted above the
fire. If, however, this is unavoidable, the extreme bottom edge of the fabric must be at
least 780mm above the top surface of the hearth or finished floor.
2.8 This appliance does not require a non-combustible hearth. It can be installed on
any hard surface. This surface should be level and sufficiently flat to enable the bottom
of the front casing and castings to be aligned horizontally. Any unevenness (Uneven
tiles, Cotswold stone etc.) should be rectified.
The appliance must not stand on carpet or other textured surfaces which may
interfere with the flow of convection air through the bottom of the appliance. The
floor surface that must be free of carpets, rugs or other fabric coverings should be at
least as wide as the appliance outer case and project forward at least 300mm from the
rear wall. In order to prevent carpet etc. being placed within this area, we strongly
recommend that the appliance is installed on a raised hearth or that the periphery of this
area is bordered by a fender.
2.9 The appliance can be fitted to a purpose made proprietary class “O” 150°
surround.
2.10 A hole 152mm (6in) dia. is required through the wall for the flue unit.
The height of the hole centre is shown in figure 1 and on the wall-fixing template
supplied with the appliance.
2.11 This appliance can be installed in any room, which contains a bath, or shower or
where steam is regularly present.

See figure 5.
The pilot burner and electrode unit is at the left front
corner of the burner.
Push in the right hand control knob and turn
anticlockwise through the ignition position marked
and up to the pilot position marked . A spark should
flash across from the pilot electrode to the pilot burner
hood. If there is no spark, check that the spark gap is as
shown.
4 GAS SUPPLY INSTALLATION
A nut & olive are provided for an 8mm pipe inlet connection to the elbow at the bottom
front of the appliance. The elbow can be rotated. The elbow includes a valve for
isolating the gas supply.
The supply pipe must be rigid material. Flexible pipe must not be used.
Concealed Supply pipe connecting from rear of the appliance
Before the appliance is installed it will be necessary to extend the supply line so that it
will project through the sealed opening at the back of the fire case and run to the elbow
at the front.
Make sure that the supply line run up to the rear opening is kept away from the area that
will be taken by the appliance case when it is installed.
Note that the centre of the appliance inlet elbow is 25mm above the floor.
The inlet elbow should be removed from the appliance and fitted to the supply pipe at
this stage.
Cut a slit in the seal at the back of the appliance case. The seal must envelop the pipe.
Cap the open end of any supply pipe installed before the wall is drilled to prevent any
debris or dust etc. entering the pipe.

5 WALL PREPARATION
5.1 Select Appliance Position
The flue must be installed so that it is at right angles to the back panel of the fire all
round the flue circumference.
For timber framed buildings make sure that the flue opening will be between studs.
When being recessed into a non-combustible wall or builders opening 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 appliance when tightening the fixing screws.
Where necessary, non-combustible packing pieces should be used to provide a
satisfactory fixing surface.
5.2 Constructing a Recessed Opening
Under no circumstances is the fire to be recessed into Timber frame constructions
or any other combustible wall.
The recess in the wall for the appliance should be to the size shown in figure 1. The
bottom of the recess should be at the same level as the finished floor in front of the
appliance.
A lintel may be required above the recess for the convection box. If in doubt, seek
expert building advice before commencing to cut the recess.

INSTALLER’S GUIDE
Page 12
5.2.1 Fitting a lintel
Whenever a lintel is required to support
the recess in the inner leaf of a
brick/blockwork building, follow the
method outlined below. See figures 7 &
8.
The lintel should be either steel (Catnic)
or reinforced precast concrete. It should
be 750mm long x 75mm deep x inner
leaf thickness.
•The opening should be, as near as
possible, centrally below a joint in the
inner leaf block.
•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.
•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
•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.
5.2.2 Preparing a Wall Cavity
•The wall cavity must
not be bridged other
than by the flue unit.
The appliance case
must not project into
the cavity between
the inner and outer
walls by more than
10mm.
•The cavity should be
sealed where the
opening has been
cut. We recommend
filling fully across
the cavity with
Rockwool or
Figure 8 Installed
Figure 7 Lintel Installation
Figure 9

INSTALLER’S GUIDE
Page 13
equivalent to at least 100mm above and each side of the recess opening. See figure 9.
•An alternative to rockwool above the opening is to seal across the top of the cavity
with superlux board or equivalent. The board should slope downwards to the back so
that any moisture will be channelled to the outside. See figure 9.
5.3 Combustible Wall Materials
•For brick or other non-combustible wall constructions, be sure to remove any
combustible wall cladding material from the area shown in figure 1.
•For Timber frame buildings, the back surface of the appliance case must be
separated from the timber frame by 25mm of non-combustible material. This can
consist of the usual 12.5mm thick plasterboard plus a 12.5mm thick sheet of non-
combustible insulating material (e.g. fibre cement board). As an option, a pre-cut
insulating sheet is available from your appliance supplier – Ask for part no. 591229.
The insulating sheet can be used to seal the annular gap between the flue unit and the
inner leaf sleeve – see section 5.5. Do not permanently fix the insulating sheet to the
wall at this stage – see section 6.2.
5.4 Cut the Flue Hole – Brick, Stone etc. Building
Cut the hole for the flue unit. Make sure that it is straight and level. Though a hammer
and chisel can be used, using a core drill is by far the quickest and simplest method for
normal brickwork.
•Before cutting the hole in the wall make sure that the height to the top surface of the
finished floor or hearth is known. The height from this surface to the flue hole centre
is shown in figure 1. The terminal position must also comply with the location
requirements given in section 2.12.
•Place dust sheets on the floor and over any furnishings etc.
•Place the template against the wall. Make sure that the centre of the flue hole is as
shown in figure 1.
•Pierce the template at the centre of the screw fixing holes and the flue hole and mark
the positions on the wall. Remove the template.
5.4.1 Core Drilling
•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 - Make sure that the minimum side clearances and
height are complied with. Remember to reposition the screw fixing holes.
•Drill the flue hole with a 152mm (6in) core drill. Where practical, it is
recommended that the hole is drilled from inside the building to about half the wall
depth with the remainder drilled from outside. This ensures that the edges of the
hole are clean on both sides.

INSTALLER’S GUIDE
Page 14
5.4.2 Hammer & Chisel Cutting
•Mark a 152mm (6in) 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 that a cardboard cylinder is formed around the flue unit and inserted
in the hole while making good. Remove the cardboard cylinder after making good.
5.4.3 Leaving a Hole - Building under Construction
•It will be convenient to use a non-corrosive metal tube 160mm diameter built into
the wall at the correct position for the flue unit.
5.5 Cut the Flue Hole –Timber Frame Buildings
•Drill the pilot hole and hole in outer wall as section 5.4.
•Since the flue will pass through combustible material in the inner leaf of the wall, a
non-combustible sleeve 203mm (8in.) diameter will be required round the flue. See
figure 9a.
Figure 9a Timber frame wall preparation

INSTALLER’S GUIDE
Page 15
•Cut a hole through the inner leaf to accommodate a non-combustible sleeve 203mm
(8in.) outside diameter. To minimise the effect of breaking through the vapour
control layer (VCL), if possible, cut the hole approximately 10mm undersize in so
that the sleeve will be forced through the layer. A recommended technique for
cutting the inner leaf is shown in figure 9a.
•Fit the non-combustible sleeve to the inner leaf. The sleeve must extend to be at least
flush with the breather membrane/timber sheathing but must not protrude more than
10mm into the cavity.
•The annular gap between the flue unit and the sleeve must be sealed to prevent air
heat and moisture passing along it. The 12.5mm insulating sheet (See section 5.3)
can be used for this. Do not permanently fix the insulating sheet to the wall at this
stage – see section 6.2
5.6 Prepare appliance Fixing holes
5.6.1 Screwing case to wall
•Recheck the position of the screw fixing holes relative to the flue hole.
•Drill the four fixing holes to a minimum depth of 42mm using a 7mm diameter
masonry drill.
•Insert four plastic wall plugs supplied.
5.6.2 Using cable retention
•Thread the two tension cables through the appliance case
side holes as shown in figure 9b.
•Move the appliance towards the recess and mark on the
recess back wall the position for the two eyebolt holes.
•Remove the appliance and drill at the marked positions
using a no.12 masonary drill.
•Insert the two fibre wall plugs supplied.
•Fit the two eyebolts.

6 FLUE TERMINAL INSTALLATION
6.1 Cutting Flue to size
•For outset appliances with surround or spacer
Measure the total wall thickness from the outside surface of the wall to the inside
face of the surround or spacer. Deduct 35mm from this measurement to obtain the
correct length of flue unit required. See figures 10 & 10a .
For appliances inset in a recess
Measure the total finished wall thickness including plaster etc. Deduct 35mm from
this measurement to obtain the correct length of flue unit required.
See figure 10.
•Mark off the flue length on the outer (air) tube measuring from the end of the
terminal.
Fig. 10 Flue Unit Installation – Brick
etc. Building Fig. 10a Flue Unit Installation – Timber
Framed Buildings

INSTALLER’S GUIDE
Page 17
•Insert the polystyrene ring between the inner and outer tubes to support them. Cut
both tubes squarely at the marked distance. Important: Remove all polystyrene from
the flue unit after cutting.
6.2 Fitting to Wall
•Fit the flue tubes firmly over the spigots
at the rear of the fire. Make sure that
the seam on the flue tube is not at the
bottom. Push on until the outer (air)
tube just covers the slots in the
appliance outer spigot. See figure 11.
•Secure the flue to the fire by drilling
through the outer flue tube and outer
spigot at a distance of between 6mm &
7mm from the cut end of the outer flue
tube and securing with the two no.6 self
tapping screws supplied. See figure 11.
•Seal the flue unit all round the circumference of the outer spigot with the tape
supplied.
•Timber frame buildings: Offer the fire complete with flue unit through the fibre
cement insulating sheet (mentioned in section 5.3). Fit a drip collar round the flue
positioned so that it will be located in the centre of the wall cavity – see figure 10a.
The drip collar can be made by wrapping a non-corrosive wire round the flue or
moulding a bead of mastic round the flue.
•Case fixing to wall: Offer the fire complete with flue unit through the wall, Insert
the four fixing screws and tighten.
•Cable retention: Fit the eyebolts onto the cables. Thread the cables through the
apliance case sides as shown in figure 9b. Offer the fire complete with flue unit
through the wall. Pull the cables taut.
•Timber frame building with combustible outer leaf (e.g. shiplap boarding): A metal
or other non-combustible end plate must be fitted on the outside of the wall. The
plate must be concentric with the flue and at least 254mm (10in) square or diameter.
See figure 10a.
•Seal the outer flue tube to the outside surface of the wall with fireclay or cement.
Make sure that the slots in the flue terminal are not closer than 8mm to the wall and
are not obstructed by cement.

8 FULL OPERATIONAL CHECKS
8.1 Check for Leaks
•Turn on the gas supply and check all joints up to the appliance gas tap for gas
soundness using a soap solution or leak detection fluid.
8.2 Check Control Operation
If the fire is turned off or the flames go out, wait at
least 3 minutes before attempting to relight. A
safety device in the control stops the fire being
turned back on until it is safe.
See figure 14.
•Turn the left hand control knob fully clockwise
•Push in the right control knob and, while keeping
it depressed, turn anticlockwise through the ignition
position marked and up to the pilot position
marked . The spark should light the pilot. The pilot flame can be seen by looking
through the gap near the left side of the coal front.
•If the pilot does not ignite, keep the knob depressed for a few seconds to purge air
from the supply pipes. Then turn back to the off position marked •and repeat the
ignition procedure.
•When the pilot has lit, keep the right hand control knob depressed for a few seconds
to allow the pilot flame to stabilise then release it. If the pilot does not remain alight
ensure that the air has been purged.
•Partially depress the right control knob and turn to the main burner position
marked . The main burner should now light at its low position.
•The left-hand knob is for burner flame adjustment. Turning it anticlockwise should
gradually increase the flame height.
•The flame height control does not have to be re-set every time the fire is lit. It can be
kept at any position enabling the customer to use the right hand control only to ignite
the burner at the set flame height.
•After checking turn the right hand knob to off. Depress the control knob partially at
the pilot position ( ), turn clockwise to off (•)and release the knob. If any
resistance is felt when turning, release the downwards pressure on the knob before
continuing to turn.

INSTALLER’S GUIDE
Page 20
8.3 Check Reference Pressure
The burner aeration is non-adjustable. The appliance is
preset to give the correct heat input on Natural Gas at 20
mbar (8in w.g) inlet pressure and no further adjustment is
necessary. The burner pressure should be checked at the
pressure test point located on the pipe connecting the gas tap
to the main burner (See figure 16). The pressure check
should be carried out using a calibrated pressure gauge after
removing the test point screw. The fire should be alight and
the left hand control knob at its fully anticlockwise setting
(Maximum flame height). The pressure setting should be within the limits shown in
section 1 of this manual (Appliance data). After checking the pressure, turn off the fire,
remove the pressure gauge and replace the pressure test sealing screw. Relight the fire
and test all gas joints for soundness using a suitable leak detection fluid.
9 FITTING FRONT UNIT
•Remove any protective film from surround.
•Locate the two lugs at the top of the front surround
