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.

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.

Page 11

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.

Page 12

Figure 1. Removal of combustible 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).

INSTALLER GUIDE

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 debris catchment space. The required fireplace, hearth, debris catchment area and clearance dimensions are shown in figure 5.

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).

Page 16

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.
