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.
* When converted using Kit 0595221
The appliance data label is located on a plate at the base of the fire. This can be seen by
removing the front cover casting.

3.2 In the United Kingdom, as supplied, this appliance can be installed in the
following situations: -
3.2.1 A masonry chimney with a minimum diameter of 175mm (7”) free from any
obstruction, and with any damper or restrictor plate in the chimney removed or secured,
Page 6
INSTALLER GUIDE

and having a minimum
effective flue height of 3m
(10ft). A masonry chimney
having a correctly installed
flue liner to BS EN 1856
part 1 or BS715 and with a
minimum flue diameter of
125mm is also acceptable.
Chair brick removal may not
be required providing at
least 50mm clearance is
available from the flue outlet
to any fireplace component.
3.2.1.1 ‘Hole-in-the-wall’ Installations
!
It is recommended that a hearth should be installed as in section 3.9 (See 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 72mm.
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 then the distance from the base of the fireplace opening in the
wall to the finished floor level should be increased to at least 147mm.
!
To protect from the risk of burns and ignition of clothing a tactile separator shall be
used. The hearth detailed in section 3.9 meets the requirements for a tactile separator. If
this is not used then a 625mm 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.
! If the lower part of the fascia (the firefront) is free standing, the recommended
reduced hearth depth is 100mm. This is necessary to support the firefront (See figure 4
for appliance dimensions).
Page 7
INSTALLER GUIDE
Figure 1. Hearth and fireplace opening dimensions

3.2.2 To a fireplace incorporating a metal flue
box conforming to BS EN 1856 part 1 or
BS715 with a minimum internal depth of
165mm. Incombustible mineral wool
insulation of not less than 50mm thickness
must be applied to the top surface of the
firebox (See figure 2) and it must stand on a
non-combustible hearth (See figure 1).
3.2.3 (See figure 3)
To a fireplace that has a precast concrete or
clay flue block system conforming to BS1289
or BS EN 1858. The appliance is suitable for
installations conforming to older versions of
BS1289 as well as the current edition. The
flue blocks must have a minimum width not
less than 63mm and a cross-sectional area not
less than 13,000mm2.Older editions of
BS1289 required a cross-sectional area of
13,000mm2. The current revision of the
standard requires 16,500mm2. This
appliance is suitable in both cases. The
total depth of the opening measured from
the finished front of the fireplace
(Including plaster, surround etc.) must be
as below:
! If the width at the rear of the precast
flue starter blocks is 300mm or greater the
depth of the opening is to be not less than
138mm. Under these conditions the
eyebolts will need to be located as close to
the sides of the starter blocks as possible.
! If the width at the rear of the precast
flue starter blocks is less than 300mm
then an additional 16mm of depth will be
required to accommodate the eye bolts.
Therefore if the starter blocks are less than
300mm wide the minimum depth of the
opening will be not less than 154mm. Page 8
INSTALLER GUIDE
Figure 3. Pre-cast Fireplace
Figure 2. Metal flue box

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.
3.2.4 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.
3.3 The following flues are suitable:
! 225mm x 225mm conventional brick flue.
If a flue liner is used, it must be a minimum of 125mm diameter. 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.
! 200mm diameter factory made insulated flue manufactured to BS 4543 or BS EN
1856 part 1.
! A properly constructed precast flue conforming to B.S 1289 or BS EN 1858.
!
A flue pipe with a minimum diameter of 175mm. See B.S 6461 Part 1 for suitable
materials. Metal flue pipes must comply with B.S 715.
! Single wall, twin wall or flexible flue liner of minimum diameter 125mm. The
materials used are stainless steel or aluminium as specified in B.S. 715 or BS EN 1856
part 1.
3.3.1 The minimum effective height of the flue must be 3m.
3.3.2 The flue must be clear of any obstruction and its base must be clear of debris.
3.3.3
The flue must be completely sealed so that combustion products do not come into
contact with combustible materials outside the chimney.
3.3.4 The flue must serve only one fireplace.
3.4 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.
3.5 The flue must not be used for any other appliance or application.
3.6
Any chimney dampers or restrictors should be removed. If removal is not possible
they must be fixed in the open position.
Page 9
INSTALLER GUIDE

3.7
If the appliance is intended to be installed to a chimney, which 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.
3.8
If the fireplace opening is an underfloor draught type, it must be sealed to stop any
draughts.
3.9 The appliance must be mounted behind a non-combustible hearth unless the
conditions of section 3.2.1.1 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 appliance must not stand on combustible materials or carpets (See figure 1).
3.10
The front face of the fireplace should be reasonably flat over the area covered by
the convector 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 convector box can be made.
3.11
The minimum height from the base of the fireplace opening 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 = 750mm.
• For a shelf deeper than 150mm: 750mm + 12.5mm for every 25mm depth over
150mm. (See Graph 1).

INSTALLER GUIDE
Graph 1. Combustible shelf clearances

3.12 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.
3.13
The appliance must not be installed in any room, which contains a bath, or shower
or where steam is regularly present.
3.14
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.
3.15 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.
3.16 Propane gas appliances must not be installed in a room, which is built entirely
below ground level (See BS 5871 Pt2).
3.17 Proprietary terminals must comply with BS EN 1856 Part 1 or BS715. 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.
3.18 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.
3.19
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, or the infirm.

3.20
The minimum allowable distance from the outside of the fascia to a corner wall
having combustible material or any other combustible surface which projects beyond
the front of the appliance is shown in figure 4. For access purposes the recommended
clearances to non combustible surfaces are shown in figure 4.
3.21 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 5). 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.

5. FIREPLACE CHECK
5.1 Fireplace check.
5.1.1 Fireplace size
The fireplace must comply with the requirements described in section 3.2. This may
entail removing the fireback and infill material behind the fireback.
5.1.2 Fireplace general condition
The fireplace floor should be reasonably flat to ensure that the convector 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 convector 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
fascia. The cladding must also not touch the fascia (See figure 5). We suggest that the
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.
5.1.3 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.
Page 15
INSTALLER GUIDE
Figure 6. Pack contents continued
Obsession

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 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 a suitable cement.
If method 2 is chosen, make sure that the areas at the back is sound enough to take the
eyebolts. If these areas have deteriorated due to prolonged use, they should be made
sound with a suitable cement.
5.1.4 Installations using a metal flue box
The whole of the top surface of the metal flue box must be covered with a minimum
50mm layer of mineral wool or equivalent insulation (See figure 2).
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 7). The positive terminal (+) is to the top as you insert.
! Depress the slider as far as it will go. This should
close the ignition circuit. Sparks should be seen tracking
from the electrode pin to the pilot tip (See figure 8).
! If there are no sparks make the following checks.
! Check condition of battery and that it is correctly
! If the above is satisfactory, check the ignition
circuitand components - see the servicing section in this
guide.
Page 16
INSTALLER GUIDE
Figure 7. Fitting battery

7. GAS SUPPLY CONNECTION
A nut and olive are provided for an 8mm pipe inlet connection to the inlet ‘T’ connector
at the bottom front of the appliance. The inlet ‘T’ connector can be rotated to allow a
connection from any direction. The inlet ‘T’ connector 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 convector box and run to the inlet
‘T’ connector at the front. The pipe run from the supply line up to the rear opening in
the convector box must be kept away from the area which will be taken by the
convector box when it is installed. 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.

8. PREPARING APPLIANCE FOR INSTALLATION
8.1 Appliance preparation
1. Remove any transit tape and packing
and inspect for any evidence of
mishandling which might affect the
performance. Each unit is flame tested
before it leaves the factory and as a result
there may be slight discolouration around
the burner ports.
2. Detach the burner unit from the
convector box by removing two screws
(See figure 9). Lift the burner unit clear.
IMPORTANT
Before continuing with the installation of this gas fire the aeration setting on
the burner must be checked. The aeration is factory set but will require
adjustment (See section 17.1).
3.
It is important that the grommet supplied in the loose parts pack is fitted to the
hole in the rear of the convector box.
8.2 Fitting the foam seal.
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 convector box. Cut the foam seal
to the required length. 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 convector box flange (See
figure 10).
8.3 The flue restrictor.
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 125mm flue
liner is used
. For flue liners greater than 125mm and all other installations the restrictor
should be fitted. There may however, be certain exceptional circumstances where fitting
Figure 10. Fitting the foam seal
Figure 9. Burner attachment points

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.
Fit the restrictor as shown in figure 11
using the two screws provided.
9. CONVECTION BOX INSTALLATION
9.1 Method 1- Front fixing to fireplace surround.
1. Make sure that the fireplace front surround area is sound enough to take the
fibreplugs 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 grommet.
3. Mark the fireplace front surround through the four
fixing holes in the side flanges of the hotbox (See figure
12).
4. Remove the hotbox. Drill four holes in the fireplace
front surround at the marked positions using a no.12
masonry drill.
5. Insert a fibre plug 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.
Page 19
INSTALLER GUIDE
Figure 11. Flue restrictor
Figure 12. Front fixing

9.2 Method 2 - Cable retention.
1.
Make sure that the relevant areas at the fireplace back are sound enough to take the
eyebolts. If these areas have deteriorated
due to prolonged use they should be
made sound with a suitable cement.
2. Drill two holes in the rear wall of the
fireplace for the eyebolt plugs. The holes
should be drilled within the range of
positions shown in figure 13 using a
no.12 masonry drill. The holes should be
equidistant each side of the centre line of
the fireplace to ensure that the appliance
finishes centrally in the opening when
tension is applied to the cables.
3. Insert a fibre plug into each hole. Use
the fibre plugs supplied with this
appliance - Never use plastic plugs
instead of the fibre plugs supplied.
Screw the eyebolts into the plugs. Make
sure that the bolts are secure.
4. Place the convector box unit close to
the fireplace but allow sufficient access
into the fireplace opening so that the
cables can be threaded through the
eyebolts and returned through the back
of the convector box. If a concealed
connection is being used, insert the
convector box into the fireplace feeding
the supply pipe through the pierced hole in the rear seal.
5. The rear of the convection box has a slot and hole each
side of the outlet opening. Assemble one end of the cable
to the top of the fire by passing it through the small round
hole and locking by positioning the cable in the adjacent
slot (See figure 14). Give the cables a pull so that they
grip.
6. Thread the cables through the eyebolts in the rear wall.
Return the cables through the holes near the bottom
corners of the convection box back panel (See figure 15).
7. Place the convection box fully back into the fireplace
opening so that it is sealed against the fireplace front
surround.
