Installer
Before continuing any further with the installation of this appliance please read the
following guide to manual handling.
The lifting weight of this appliance (kg) is as below:
Model Heat Engine Firefront Combined Weight
Allure 20.24 12.66 32.90
This appliance is heavy. We therefore recommend that two people should be
sufficient to lift the fire. If fitting or moving the fire alone we recommend the use of
suitable lifting apparatus.
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, burner compartment walls and ceramic
gravel 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.

5.6 Chimney preparation.
5.6.1 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.
5.6.2 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
5.7 Fireplace preparation.
5.7.1 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
5.7.2 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.
5.7.3 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.
5.7.4 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.
5.7.5 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.

Figure 1. Removal of combustible cladding

5.8 The hearth.
The appliance must be mounted behind a non-combustible hearth unless the
conditions of section 5.10.2 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.
5.9 Fireplace clearances.
5.9.1 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 = 750mm.
• For a shelf deeper than 150mm: 750mm + 12.5mm for every 25mm depth over
150mm (See Figure 2).

5.10.2. ‘Hole-in-the-wall’ Installations
 It is recommended that a hearth should be installed as in section 5.8.
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
105mm. 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 180mm.
5.11 Flues.
5.11.1. 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.
INSTALLER GUIDE
© Baxi Heating U.K. Limited 2010. Page 16
Figure 5. Fireplace area.

5.11.2. 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.
5.11.3. The flue must not be used for any other appliance or application.
5.11.4. 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.
5.12 Propane appliances.
Propane gas appliances must not be installed in a room that is built entirely below
ground level (See BS 5871 Part 2).

8. FIREPLACE CHECK
8.1 Soundness for appliance attachment
Two primary methods of retaining the appliance are provided: -
1) By fixing to the fireplace front.
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 12 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 wood screws. 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.
8.2 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.
