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 (kg) of this appliance is as below:
Model Dream/Masquerade/Excelsior 8.64 13.35 21.99 Harmony 8.64 3.55 12.19 Petrus 8.64 11.63 20.27 Classica 8.64 11.0 19.64
One person should be sufficient to lift the fire. If for any reason this weight is considered too heavy then obtain assistance.
Heat Engine Firefront Combined Weight
- 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 appliance does not contain any component manufactured from asbestos or asbestos related products.

INSTALLER GUIDE
Figure 1. Removal of combustible cladding (Fascia may differ from that shown).
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 underfloor draught type, it must be sealed to stop any draughts.
3.7.2 The fireplace floor should be reasonably flat to ensure that the convection box can be installed without it rocking and so that a good seal can be made at the bottom front of the box.
3.7.3 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.
3.7.4 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.
3.7.5 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.
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.

3.10.1.1 ‘Hole-in-the-wall’ Installations.
- It is recommended that a hearth should be installed as in section
3.8.
- Homeflame Dream/Masquerade/Excelsior/Classica firefront
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 100mm. 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. 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.
- Homeflame Harmony firefront
If a hearth is not 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.
3.10.2 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 7. The top, sides and rear surface of the metal flue box must be covered with a 50mm layer of mineral wool or equivalent insulation (See figure 7).
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 non­combustible hearth. The hearth material must be at least 12mm thick.

INSTALLER GUIDE
Figure 8. Precast or clay flue block system
3.10.3 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 8. 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.
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 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 are met.

3.10.3
INSTALLER GUIDE
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 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.

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 1 is chosen, make sure that the front surround area is sound enough to take the fibre / wooden plugs and woodscrews. If necessary, make sound with 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 eyebolts and screws. If these areas have deteriorated due to prolonged use, they should be made sound with suitable cement.
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.
