INSTALLATION INSTRUCTIONS
IMPORTANT NOTES
This appliance is a high efficiency, flueless catalytic flame effect gas fire. It provides radiant and con-
vected warmth both efficiently and safely utilising the latest type catalytic converter and burner tech-
nology. The appliance does not require a flue system of any type as the catalytic converter cleans the
flue products to provide a complete combustion system, which is intrinsically safe. It is designed to oper-
ate on Natural Gas (see data badge) and is factory set for operation on the gas type, and at the pres-
sure stated on the appliance data plate.
The appliance incorporates a combustion monitoring system (Oxygen Depletion System). It must not be
adjusted or put out of operation. If replaced then manufacturer’s original parts must be used.
It is the LAW that all gas appliances and fittings are installed by a competent person and in accordance
with the Gas Safety (Installation and Use) Regulations 1998, the relevant British Standards for
Installation, Codes of Practice and the Manufacturers' Instructions.
At the time of writing, GAS SAFE registered operatives are the only class of person considered as 'com-
petent' by the HSE under the above regulations. The installation shall also be carried out in accordance
with the following:
Failure to comply with the above could lead to prosecution and deem the manufacturer’s warranty
invalid.
This appliance must be installed in accordance with the rules in force and used only in a sufficiently ven-
tilated space. The appliance is designed to fit various types of situations as described in sections 3.0 and
4.0. The appliance must be installed in a correctly sized room (see section 3.1), and the correct purpose
provided ventilation must be provided (see section 4.1). It should be noted that heaters create warm air
currents. These currents move heat to wall surfaces next to the heater. Installing the heater next to
vinyl or cloth wall coverings or operating the heater where impurities in the air (such as tobacco smoke,
candle smoke etc.) exist, may cause the walls to become discoloured.
This appliance is intended as a secondary source of heat only and should not be used in a room without
some form of background heating present. If the appliance is used in a room as the sole source of heat,
then condensation may occur on colder surfaces within the room.
On first light up of a new appliance, initial curing of high temperature paint and burning off of lubricants
may occur for the first few hours of operation. During this period some smoke may be emitted from the
outlet grille, this should be no cause for concern. Accordingly, the room should be well ventilated with
all windows and doors open during this period. During this period the appliance may cause smoke alarms
to sound. If this happens, reset the alarms, but do not remove the batteries.
Consult ALL instructions before installation and use of this appliance. This appliance is free from any
asbestos material.

APPLIANCE DATA
INSTALLATION REQUIREMENTS
The fire has been designed to be installed in two main applications; either to fit into a suitable opening
created in the inner leaf of an outside wall or false chimney breast/extended fire surround built to con-
ceal the appliance. The appliance can also be fitted into an unserviceable or inoperative fireplace served
by a natural draught flue but the old flue must be sealed off. It will be necessary to ventilate the old
flue to prevent condensation and dampness forming, however any air vent used to ventilate the old flue
must not be sited within 500mm of this appliance. If the flue can be ventilated to the outside of the
building then this is usually the best solution. If in doubt then advice should be sought from a local
building control officer.
The appliance must be installed onto a suitable non-combustible insulating surface at least 12 mm thick
covering the entire base area of the box. The fire must be used with a back panel capable of with-
standing 150°C minimum. Any combustible materials directly behind the fire frame (or back panel) and
close to the cavity box of the fire must be removed and replaced with non-combustible material such
as cement, browning, 'Superlux' board or equivalent materials.
ROOM SIZING
The room size should be a minimum of 27m3(e.g. 11’ x 11’ x 8’) to allow adequate circulation of air
and ensure the correct operation of the fire. This volume may include adjacent spaces but these spaces
must not be separated by a door. To calculate a room size in cubic metres (m3) divide the room volume
in cubic feet (ft3) by 35.3.
SITE REQUIREMENTS
This appliance may be installed in any room in the home except bathrooms. If the appliance is to be
fitted in a bedroom then an electronic carbon monoxide detector complying with the current edition of
BSEN 50291 must be installed in the same room as the appliance. For maximum safety it is recom-
mended that such device is continuously (mains) powered and arranged in such a way that the gas sup-
ply to the appliance is isolated in the event of an alarm. The selection and installation of such device
shall be in accordance with the current edition of BSEN 50292, and the user must be briefed regarding
the use and maintenance of such a device. Installation in living rooms is common, however other rooms
such as kitchens, dining rooms and hallways are permitted, providing a suitable gas supply is available,
and rooms sizing and ventilation requirements are strictly adhered to (see sections 3.1 and 4.1).
The appliance is designed to be versatile, and as such will operate correctly when exposed to normal
gentle draughts experienced within the home. It is not recommended, however that the appliance be
installed in areas where it is likely to be directly exposed to persistent strong draughts, that may be
generated by outside doors, windows, air vents, air conditioning units, extractor fans, ceiling fans etc.
See section 4.1 for more information on ventilation.

SITE REQUIREMENTS (continued)
Basic opening sizes (all dimensions in mm)
The basic opening dimensions for the appliance are as follows;
The opening must be within these sizes in order to accommo-
date the full depth of the fire box in non-combustible applica-
tions. Applications involving combustible materials e.g. timber
battens in false chimney breasts, must use appropriate clear-
ances and insulation methods as described in the relevant sec-
tion of these instructions. Opening depth ‘c’ includes any plas-
ter, cement or infill/back panels that form part of the installa-
tion.
Consideration for cable fixings, any hearth that may be
required etc. should be made in addition to the basic sizes
given in table 1.
•Cable fixings at rear - allow an extra 20mm depth.
•Hearth to be installed - allow the height of the hearth (minimum
50mm).
The appliance must be sited on a solid base (indicated in figure
1). This base may be combustible (i.e. laminate or wooden
flooring) but must not be carpet or fabric of any kind. If the
room in which the appliance is to be installed is carpeted or has
a fabric floor covering then a small solid hearth will be required,
meeting the dimensions specified in table 1 and illustrated in figure 2.
In all installations, the wall or back panel of the installation must be flat, non-combustible and meet the
dimensions specified in table 1 and illustrated in figure 2.
The appliance may be installed as a ‘hole in the wall’ type installation, however a small hearth or ledge
must be provided to support the base of the appliance and decorative facia. In this situation the thick-
ness of the hearth or ledge may be as desired, but it must have the strength to support the weight of
the appliance and the facia.

SITE REQUIREMENTS (continued)
Clearances to non-combustibles
Non combustible surfaces are defined as brick, metal, marble, concrete etc. and also a number of man-
made materials impervious to flame. If in doubt refer to the material manufacturer for further infor-
mation before proceeding with installation.
The wall/back panel for the opening must always be non-combustible. Bare plasterboard must be pro-
tected by non-combustible plaster or replaced with non-combustible material (e.g. Superlux board).
Any gap between wall boards and the wall must be filled using glass fibre insulation, silicone mastic or
similar material to prevent heat ingress.
Any type of fire surround used with this appliance must be adequately sealed to the wall and floor to
prevent excess draughts around the back of the fire. The temperature rating of any surround used must
be 150°C minimum.
Clearances to the sides of the appliance are 100mm (4”). Clearance to the front of the appliance is
500mm (20”).
The sides and back of the appliance may be installed directly onto a non-combustible surfaces.
A non combustible shelf of any depth may be positioned above the appliance provided it is no closer
than 200 mm from the top of the appliance glass panel and the wall above the appliance is non com-
bustible. The shelf itself and any articles placed on it must also be tolerant of high temperatures.
Clearances to combustible materials
Combustible materials are defined as wood, fabrics, or other materials likely to combust if exposed to
flame. Generally, any material, which is likely to discolour, melt or misshape when exposed to moder-
ate heat, should be considered as a combustible material or surface.
Clearance to the sides of the appliance facia are 100mm (4”) but curtains, drapes and other fabrics are
not permitted within a distance of 500mm (20”) of the appliance sides. No such materials are permit-
ted directly above the appliance regardless of distance.
The minimum clearance to the ceiling above the appliance is 800mm (31.5”) measured from the top of
the appliance glass panel.
Combustible materials should not be positioned directly in front of the appliance within a distance of
one metre.
A combustible shelf may be fixed to the wall above the fire, providing that it complies with the dimen-
sions given below.
The shelf depth may be greater but the height must also be increased accordingly. An increase in height
of 25 mm is required for every 12.5 mm of additional shelf depth. For shelves that are too low protec-
tive devices can be used such as metal heat deflectors, but it must be assured that the shelf does not
reach an unacceptable temperature before relying on such a solution.
Under no circumstances should any electrical equipment e.g. plasma screen TV sets etc. be positioned
on the wall above the appliance.
Clearance to the sides and rear of the firebox are a 75mm (3“) air-gap. Clearance to the top of the fire-
box is a 100mm (4”) air-gap.
It should be established that any mirrors or picture frames etc. to be positioned on the wall above the
appliance are able to withstand prolonged exposure to moderate heat and moisture before proceeding
with their installation.
If the appliance is to be mounted on a dry lined wall or a timber framed construction wall then the
integrity and ability of the wall to carry the weight of the appliance must be confirmed. It is important
in these circumstances that any vapour control barrier is not damaged, and that any structural mem-
bers of the house frame are not damaged - refer to section 6.5.

VENTILATION
A minimum of 100 cm2purpose provided ventilation is required for this appliance. This may be achieved
either with one vent 100 cm2at a high or low position in the room, or split ventilation i.e. 50cm2 be
installed at high level and 50cm2be installed at low level within the room. An openable window or
equivalent is also required.
To reduce the possibility of draughts, road noise or insects entering the room via the air vent, we rec-
ommend the use of “Black Hole”, “Vortex” or “Centurion” type vents featuring internal baffles. The
requirements of any other gas, oil or solid fuel appliances operating in the same room or space must
be taken into consideration when assessing ventilation.
Any ventilation fitted must comply with BS5871 part 4 and BS 5440 part 2.
Ventilation fitted under, or within immediate vicinity of the appliance must not be used as it may
adversely effect performance of the ODS system. For Republic of Ireland refer to the current edition of
IS813 and any relevant rules in force. The appliance shall not be installed within one metre of any
existing air vent, and any new air vent shall not be installed within one metre of the appliance.
UNPACKING THE APPLIANCE
Lift off the remaining packaging components. Check that the components supplied correlate with the
component checklist. Please dispose of all the packaging materials at your local recycling centre.
COMPONENT CHECKLIST
APPLIANCE INSTALLATION
Note: Ensure that the gas supply is isolated before commencing installation of the appliance.
The fireplace opening and environment must be in compliance with specifications laid down in the
appropriate sections of these instructions.
PREPARING THE APPLIANCE
Remove the appliance from its carton as described previously and stand on a dustsheet. Remove the
hood and glass panel and place safely to one side.
Knock out holes are provided in the rear and sides of the firebox for use where concealed pipework is
required. Note: Knock out holes are also provided in the sides of the inner firebox if a side-entry pipe
routing is required, but it is essential to seal these holes with grommets. Knock out the appropriate
hole in the cavity box with a sharp tap from a hammer and fit the rubber grommet supplied. A small
incision can now be made in the rubber to slip snugly around the outside of the supply pipe and sleev-
ing.
Warning : Do not install or use the appliance without this seal in place.

GAS SUPPLY ROUTES
Following preparation of the fixing method, the concealed gas supply (if required), can now be installed.
When the opening is ready for installation the gas supply can be routed. If the gas pipe has been
sleeved the ends of the sleeving must be sealed. The end of the 8mm pipe should be temporarily sealed
to prevent the ingress of debris during fixing.
An inlet restrictor elbow is supplied as part of the appliance.
All installation pipework must be in accordance with the current edition of BS 6891, and for timber
framed dwellings, the current edition of IGE/UP/7.
In order to avoid unnecessary pressure drops, no more than 1.5m of 8mm diameter pipe must be used.
If a concealed gas connection is to be made, the supply pipe should always be sleeved through walls
and floors using the shortest possible route. For concealed supply pipe routing, pipes must (where pos-
sible) be vertical and providing there is sufficient wall thickness available, they should be placed in pipe
chases. Horizontal pipe runs should be avoided.
Prior to chasing a solid wall, an inspection should be made to note the proximity of any cables/sockets
outlets which may already be buried. Pipes must be secured using suitable clips and protected against
corrosion. Ideally factory finished protected pipework and fittings should be used. Joints should be kept
to a minimum and compression fittings must not be used. The pipework installation must be tested for
tightness before any protection is applied and/or the pipework and fittings are buried.
INSTALLATION METHOD 1 (against a non-combustible inside wall)
This method requires no modifications to the internal wall of a property and is achieved by
using either a surround with extended rebate or a false chimney breast of minimum 105mm
internal depth. If cable fixings are to be used then the minimum depth should be 125mm.
A false chimney breast should be installed, taking into account any guidance given in the section on
timber framed buildings as far as insulation and clearances are concerned. When the false chimney
breast is constructed from combustible materials the firebox must be separated from any combustible
materials by a minimum 75mm air gap at the sides and rear and 100mm air gap above the firebox.
Alternatively the firebox may be insulated with 75mm of fibre glass wool or rock wool to the sides, rear
and 100 mm to the top.

INSTALLATION METHOD 2 (recessing into a non-combustible wall)
This method allows for installation of the appliance with the rear of the firebox recessed into
the inner leaf of a cavity wall. This should enable a standard fire surround and back
panel/hearth set to be fitted to the wall with the fire presented naturally in a flush fitted
manner. The structural integrity of the wall must be maintained.
Check the cavity insulation type (if applicable). If cavity insulation is of a loose fill variety, take pre-
cautions to prevent excessive loss of material when the inner leaf is opened up by packing the cavity
firmly with a minimum 50mm of rockwool or glass fibre. This will hold back any loose material now or
in the future.
To maintain the structural integrity of the wall it is recommended that a suitable lintel is fitted. It is
sometimes possible to install this appliance without a lintel, depending on the type of wall. The guid-
ance of a qualified professional or local building control officer is essential to confirm this.
Mark out the area of the proposed fireplace opening on the wall. Obtain a suitable concrete or steel lin-
tel from a builder's merchant. Drill four holes at the corners of the lintel position and squarely over the
fireplace opening, and if possible centrally under a block joint . Clear out the block work in the area and
insert the lintel by saw, or stitch drill and chisel. Do not dry bed the lintel - always bed on mortar and
securely slate pin. Clear out the block work from below the lintel to form the opening for the firebox to
be inserted.
The top of the exposed area of cavity must be sealed against the ingress of moisture dripping from
above. The best way to do this is a cavity tray but an easier and quicker method is to affix a 'Supalux'
or equivalent board into the cavity. Slope the board towards the outside wall and support with screws,
cement, 'Unibond' or silicone mastic etc. This will guide all moisture, harmlessly, to the outside wall.
The exposed sides of the cavity must be packed with a suitable depth (minimum 50mm) of glass fibre
or rock wool to prevent draughts and heat loss, even if no loose fill material is present. It is good prac-
tice to insulate the rear of the fire from the cavity to prevent heat loss and condensation.
The hearth may now be put in place (If fitted). Again this should not bridge the cavity where it proj-
ects into the wall space. Finally install the fireplace or fire surround and back panel/marble to its fin-
ished location.

INSTALLATION METHOD 3 (timber framed buildings)
Where removal of any part of a timber frame is undertaken the structural integrity of the wall must be
retained. The advice of your local building control officer should be sought. If the property is under any
NHBC warranty it is also advised that their advice on this kind of modification is sought.
Either of the two preceding installation methods may be adapted for timber framed buildings, provid-
ing extra care is taken in ensuring combustible materials are adequately protected from the effects of
heat.
The appliance must be installed in accordance with the British Gas documents DM2 and DM3 or the
Institute of Gas Engineers published procedure document IGE/UP/7.
Special attention must be paid to the location of studwork frames of the inner leaf and the appliance
positioned accordingly. Wires and pipes that run within the wall must also be taken into account.
Installation as per method 1 (against inner wall)
When using this method of installation the following amendments should be incorporated. A 75mm air
gap or 75mm of
insulation (e.g.
rockwool) must be
provided between
combustible materi-
als and the sides
and rear of the cav-
ity box. A 100 mm
air gap or 100mm of
insulation (e.g.
rockwool) must be
provided to the top
of the cavity box. It
is also a good idea
to enable as much
airflow as possible,
into and out of the
area behind the fire
without excessive
heat loss from the
room when the fire is off.
Installation as per method 2 (recessing into a wall)
When setting the appliance into the wall find a suitable position between frame timbers and open up
the hole. Secure
back the damp proof
membrane to pre-
vent ingress of
damp.
Again 50mm insula-
tion plus a 12mm
thick fire retardant
board, 'Superlux' or
equivalent, must be
provided between
combustible materi-
als and the sides
and rear of the cav-
ity box. 100 mm of
insulation plus a 12
mm thick fire retar-
dant board,
'Superlux' or equiv-
alent, must be provided to the top of the cavity box. The exposed cavity should be sealed off using non-
combustible board, ('Supalux' or equivalent), made into a 4-sided box. It is also good practice to fur-
ther insulate the cavity with a 50mm layer of Rockwool outside the Superlux box. Note that the appli-
ance should not be allowed to bridge the cavity in this installation method. It is also a good idea to
enable as much airflow as possible, into and out of the area behind the fire without causing excessive
heat loss from the room when the fire is off.
