INSTALLER GUIDE

1. SAFETY AND UNPACKING
Installer
Before continuing any further with the installation of this appliance please read the
following guide to manual handling.
The lifting weight of the heat engine and convection box is 11.5kg.
One person should be sufficient to lift the heat engine and convection box. If for
any reason this weight is considered too heavy then obtain assistance.
When lifting always keep your back straight. Bend your legs and not your back.
Avoid twisting at the waist. It is better to reposition your feet.
Avoid upper body/top heavy bending. Do not lean forward or sideways whilst
handling the heat engine.
Always grip with the palm of the hand. Do not use the tips of fingers for support.
Always keep the heat engine and convection box as close to the body as possible.
This will minimise the cantilever action.
Use gloves to provide additional grip.
Always use assistance if required.
This product uses fuel effect pieces and burner compartment walls 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. RCF waste is classed as a stable, non-reactive hazardous waste and
may be disposed at a landfill licenced to accept such waste. Protective clothing is
not required when handling these articles, but we recommend the use of suitable
gloves to prevent irritation. We also 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.

INSTALLER GUIDE

Where no specific instructions are given, reference should be made to the relevant
British Standard Code of Practice.
3.2 Ventilation requirements.
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.
3.3 The Atmosphere sensing device (ASD).
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.
3.4 Fireguard requirements.
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, the infirm or pet animals.
3.5 Room considerations.
3.5.1 This appliance must not be installed in any room that contains a bath or shower
or where steam is regularly present.
3.5.2 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.
3.5.3 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.
3.6 Chimney preparation.
3.6.1 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.
Page 10

INSTALLER GUIDE

3.6.2 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
3.7 Fireplace preparation.
3.7.1 If the fireplace opening is an under floor draught type, it must be sealed to stop
any draughts.
3.7.2 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.
3.7.3 If the appliance is to be fitted against
a wall with combustible cladding, the
cladding must be removed from the area
covered by the fascia. The cladding must
also not touch the fascia (See figure 1). We
suggest that the actual fascia 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.
3.7.4 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.
3.8 The hearth.
The appliance must be mounted behind a non-combustible hearth unless the
conditions of section 3.10.1.1 are met (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.

cladding (fascia may differ to that
shown).
INSTALLER GUIDE

3.9 Fireplace clearances.
3.9.1 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 below: -
•For a shelf up to 150mm deep
Minimum height = 760mm.
•For a shelf deeper than 150mm
Minimum height = 760mm + 12.5mm for every 25mm depth over 150mm.
(See figure 2).
3.9.2 The minimum mandatory side clearance to combustible surfaces projecting
beyond the front of the appliance is 100mm. For access purposes a 10mm clearance
to non-combustible surfaces is recommended on the left side of the appliance, on the
right side the recommended clearance is 50mm for access to the slider control.
3.10 Installation options.
In the United Kingdom, as supplied, the appliance can be installed in the following
situations: -
3.10.1 Conventional fireplace and hearth.
To a fireplace complete with surround and hearth as shown in figure 3 and complying
with BS1251 after removal of the fireback and sufficient material behind the fireback
for a debris catchment space. The required fireplace and debris catchment area are
shown in figure 4.

INSTALLER GUIDE

Page 13
3.10.1.1 ‘Hole-in-the-wall’ Installations
It is recommended that a hearth should be installed as in figure 1.
 If fitting a fascia that has a firefront designed to sit on a hearth, a reduced depth
hearth is recommended. 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 heat engine must be installed so that distance from

Figure 4. Fireplace area.
INSTALLER GUIDE

the base of the fireplace opening in the wall to the finished floor level shall be at
least 100mm. Where there is no floor covering or carpet, and the floor is of a
type that is likely to be covered in such a way in the future, then the distance
from the base of the fireplace opening in the wall to the floor level should be
increased to at least 175mm.
 If fitting a fascia that does not have a separate firefront and a hearth is not fitted,
the heat engine must be installed so that distance from the base of the fireplace
opening in the wall to the finished floor level shall be at least 100mm. Where
there is no floor covering or carpet and the floor is of a type that is likely to be
covered in such a way in the future then the distance from the base of the
fireplace opening in the wall to the floor level should be increased to at least
175mm.
 To protect from the risk of burns and ignition of clothing a tactile separator shall
be used. The hearth detailed in section 3.8 meets the requirements for a tactile
separator. If this is not used then a 672mm long fender, kerb, horizontal bar, or
other barrier, being fixed not less than 50mm above floor level and positioned
300mm in front of the fixing plane of the fire will meet the requirement.
3.10.2 Metal flue box and hearth.
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. The top of the metal
flue box must be covered with
a 100mm layer of mineral wool
or equivalent insulation (See
figure 5).
Important Note: Where the
flue box has a base sheet that
is single wall (i.e. a single
metal sheet) the flue box must
be mounted on a non-
combustible hearth. The hearth
material must be at least
12mm thick.
Page 14

Figure 5. Metal flue box dimensions
INSTALLER GUIDE

3.10.3 Precast concrete or clay flue block system and hearth.
To a precast concrete or clay flue
block system conforming to BS1289
with dimensions as in figure 6. The
current versions of BS1289 and BS
EN 1858 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.
3.11 Flues.
1. 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
BS EN 1856 Part 1. 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 BS EN 1858. This system is only suitable if the conditions stated in section 3.10.3
are met.
2. 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
Page 15

Figure 6. Precast or clay flue block system
INSTALLER GUIDE

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. The flue must not be used for any other appliance or application.
4. 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.
3.12 Propane fires.
Propane gas appliances must not be installed in a room that is built entirely below
ground level (See BS 5871 Part 2).

INSTALLER GUIDE

5. FIREPLACE CHECK
5.1 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 9 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
otherwise impractical. N.B. It is unwise to attempt to drill into marble without the
proper tools and equipment.
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 suitable
cement.
If method 1 is chosen, make sure that the front surround area is sound enough to
take the fibre plugs and woodscrews. If necessary, make sound with suitable cement.
5.1.1 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 5).
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.

6. 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 locations for the +ve and -ve terminals
are marked on the battery holder.
Rotate the control pivot bracket clockwise as far
as it will go and hold in this position (See figure
9). This should close the ignition circuit and
sparks should be seen tracking from the
electrode pin to the pilot tip (See figure 9).
If there are no sparks
make the following
checks.
 Check condition of
battery and that it is
correctly fitted.
 If the above is
satisfactory, check the
ignition circuit and
components - see
section 16 which is the servicing and parts replacement section in this guide.
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 and 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 convection box and run to the ‘T’
connector 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 4).
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.

INSTALLER GUIDE

8. PREPARING APPLIANCE FOR INSTALLATION
1. Detach the burner unit from the convection box by removing two screws (See
figure 10). Lift the burner unit clear.
2. Fit the two “U” section seals to the bottom edges of the convection box side
flanges (See figure 11).
3. It is important that the grommet
supplied in the loose parts pack is
fitted to the hole in the rear of the
convection box.
4. For concealed connection only:
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.
6. The heat engine or fascia will have a canopy shield
supplied with it. Fit this to the convected air outlet of the
appliance using the three self tapping screws supplied.
The design of the canopy shield may differ from that
shown (See figure 12).
