2. SAFETY AND UNPACKING
Installer
Before continuing any further with the installation of this appliance please read the
following guide to manual handling:
 The approximate lifting weight (kg) of this appliance is as below:
Model Heat Engine Fascia, firefront and ash pan Combined Weight
Blenheim 4.9 3.9 8.8
Dream 4.9 11.7 16.6
Prelude 4.9 13.4 18.3
One person should be sufficient to lift the fire. 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 fire.
Always grip with the palm of the hand. Do not use the tips of fingers for support.
Always keep the fire 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 licensed to accept such 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 product does not contain any component manufactured from asbestos or
asbestos related products.

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.
4.3 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 manufacturer’s
replacement part should be fitted. The individual A.S.D components are not
replaceable.
4.4 Fireguard requirements.
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, the infirm and pet animals.
4.5 Room considerations.
4.5.1 This appliance must not be installed in any room that contains a bath or shower
or where steam is regularly present.
4.5.2 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 guide. If the fan is likely to affect the appliance, the appliance must not be
installed unless the fan is permanently disconnected.

INSTALLER GUIDE

4.5.3 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.
4.6 Chimney preparation.
4.6.1 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.
4.6.2 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
4.7 Fireplace preparation.
4.7.1 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
4.7.2 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.
4.7.3 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.
4.7.4 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.
4.7.5 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.

cladding (Fascia may differ from that
shown).
INSTALLER GUIDE

4.8 The hearth.
The appliance must be mounted behind a non-combustible hearth unless the
conditions of section 4.10.1.1 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.
4.9 Fireplace clearances.
4.9.1 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 = 760mm.
• For a shelf deeper than 150mm: 760mm + 12.5mm for every 25mm depth over
150mm (See Figure 2).

4.10 Installation options.
In the United Kingdom, as supplied, the appliance can be installed in the following
situations: -
4.10.1 Conventional fireplace and hearth.
To a fireplace complete
with surround and
hearth as shown in
figure 4 and complying
with BS1251 after
removal of the fireback
and sufficient material
behind the fireback for a

INSTALLER GUIDE

4.10.1.1 ‘Hole-in-the-wall’ Installations.
 It is recommended that a hearth should be installed as in section 4.8 (See figure
4).
 If a hearth is not fitted or 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 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 4.8 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.
 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
3 for appliance dimensions).
4.10.2 Metal flue box and hearth.
The appliance can be installed to a fireplace incorporating a metal flue box complying
with the constructional requirements of the current edition of BS 715 and with a flue
conforming to BS EN 1856 part 1. The dimensions of the flue box must conform to
those shown in figure 6
Important Note:
The top surface of the metal
flue box must be covered with
a 100mm layer of mineral wool
or equivalent insulation (See
figure 6).

Figure 6. Metal flue box dimensions
INSTALLER GUIDE

4.10.3 Precast concrete or clay flue block system and hearth.
The appliance can be installed
to a precast concrete or clay
flue block system conforming
to BS EN 1858 with
dimensions as in figure 7.
BS 1289 part 1 recommends
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.

INSTALLER GUIDE

4.11 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 Part 2.
 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 4.10.3
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
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 2m 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.
4.12 Propane appliances.
Propane gas appliances must not be installed in a room that is built entirely below
ground level (See BS 5871 Part 2).
