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 0595231.
The appliance data label is located on a plate at the base of the fire. This can be seen by
removing the firefront casting set / firefront.

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. The
appliance is designed to
cater for low lintel
installations (min height
505mm) providing a minimum distance of 25mm is maintained between the lintel and
the front face of the fireplace (i.e. 25mm rebated fire surround).
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 5
for appliance 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 150mm. Incombustible mineral wool
insulation of not less than 50mm thickness must be applied to the top surface of the
Page 7
INSTALLER GUIDE
Figure 1. Hearth and fireplace opening dimensions
See Section 3.14

firebox (See figure 2) and it must stand on a
non-combustible hearth (See figure 1).
3.2.3 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 not less than 120mm (See figure 3).
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.
! A properly constructed precast flue conforming to B.S 1289 or BS EN 1858.
! A flue pipe with a minimum diameter of 127
mm. See B.S 6461 Part 1 for suitable
materials. Metal flue pipes must comply with BS EN 1856 Part 1 or B.S 715.
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.
Page 8
INSTALLER GUIDE
Figure 2. Metal flue box

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.
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 (N.B.
conglomerate marble hearths are considered as non-combustible) unless the conditions
of section 3.2.1.1 are met. 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).
Page 9
INSTALLER GUIDE
Figure 3. Pre-cast fireplace

3.10
The front face of the fireplace should be reasonably flat over the area covered by
the hotbox 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 hotbox can be made.
3.11 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.
3.12
The appliance must not be installed in any room, which contains a bath, or shower
or where steam is regularly present.
3.13
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.
3.14
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).
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
Page 10
INSTALLER GUIDE
Graph 1. Combustible shelf clearances

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 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 4). 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.
3.18 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 shown in figure 5.
Figure 5 also gives the necessary access clearance from a non-combustible surface at
both sides.
3.19 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.
3.20 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.
3.21
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, or the infirm.

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 hotbox 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
hotbox 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 4). 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.
5.1.3 Soundness for appliance attachment
Two primary methods of retaining the appliance are provided: -
1) By fixing to the fireplace front surround (Not available on Blenheim, Sonnet,
Homeflame Traditional, Anthem, Debut, Aura 2 or Minima models).
2)
Using concealed tension cables fixed to the rear of the fireplace opening (Available
on all models).
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 wall plugs and screws. If necessary, make sound with a suitable cement.
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 eyescrews. 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
Page 16
INSTALLER GUIDE

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
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. 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.
7. GAS SUPPLY CONNECTION
A nut and olive are provided for an 8mm pipe inlet connection to the inlet elbow at the
bottom front of the appliance. The inlet elbow can be rotated to allow a connection from
any direction. The inlet elbow 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 hotbox and run to the inlet elbow
at the front. The pipe run from the supply line up to the rear opening in the hotbox must
be kept away from the area which will be taken by the hotbox when it is installed. Note
that the centre of the appliance inlet elbow is 25mm above the fireplace floor. The inlet
elbow 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 of the fire. 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 hotbox by
removing two screws (See figure 8). 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 ‘H’ supplied in
the loose parts pack is fitted to the hole in the rear
of the hotbox.
8.2 Fitting the ‘push on’ fascia trim for the
Blenheim, Sonnet, Homeflame Traditional,
Anthem, Debut, Aura 2 & Minima models.
1.
The fascia is supplied in three pieces. Remove any protective film. The two longer
pieces are the left and right sides. The shorter piece is the top. The left and right hand
pieces have folded edges, one of which is shorter than the other. This shortened edge
should be fitted at the inner top on both sides. Fit the top piece last and centralise (See
figure 9).
8.3 Fitting the foam seal (All models).
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 hotbox. If the fire is fitted
with ‘push on’ style fascia trim as in 8.2 above the foam seal will be fitted over the
flanges of the fascia.
It is therefore important to ensure that the fascia is positioned
correctly before fitting the foam seal. 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 hotbox flange (See figure 10).
Figure 9. Fitting the fascia
Figure 8. Burner attachment points

8.4 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 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.
The restrictor is packed flat with the appliance
and will require bending prior to fixing. Bend
the restrictor as shown in figure 11.
Fit the restrictor as shown in figure 12 using the
two ‘B’ screws provided.
8.5 Fitting the Quantum fascia hanging
bracket.
1. Supplied in the loose parts pack is a fascia
hanging bracket ‘E’. Fit this to the top of the
hotbox using two of the ‘A’ screws supplied.
(See figure 13).

9. HOTBOX INSTALLATION
9.1 Method 1- Front fixing to fireplace surround (Not available on Blenheim,
Sonnet, Homeflame Traditional, Anthem, Debut, Aura 2 or Minima models because
of the ‘push on’ fascia trims).
1. Make sure that the fireplace front surround area is sound enough to take the wall
plugs and screws. If necessary, make sound with a
suitable cement.
2. Place the hotbox centrally in the fireplace in the
position in which it is to be permanently installed. If a
concealed connection is being used, insert the hotbox
into the fireplace feeding the supply pipe through the
