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.

4.2 In the United Kingdom, as supplied, the appliance can be installed in the
following situations: -
4.2.1 To a fireplace complete with surround and hearth as shown in figure 1 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 1.
Figure 1. Hearth and fireplace opening dimensions.

INSTALLER GUIDE
Page 10

4.2.1.1 ‘Hole-in-the-wall’ Installations
 It is recommended that a hearth should be installed as in section 4.9.
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 100 mm. 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 ash
pan 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.
4.2.2 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 2.
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 non-combustible hearth. The hearth
material must be at least 12mm thick.
4.2.3 To a precast concrete or clay flue block system conforming to BS EN 1858 with
dimensions as in figure 3 (A spacer frame is available for precast flue installations that
are shallower than the 225mm
dimension shown in figure 3 -
See section 2 headed
‘Accessories’). 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.
4.2.4 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.
Figure 2. Metal flue box dimensions

INSTALLER GUIDE

4.3 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 4.2.3 are met.
4.4 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.
4.5 The flue must not be used for any other appliance or application.
4.6 Any chimney damper or restrictor should be removed. If removal is not possible,
they must be secured in the open position.
Figure 3. Precast or clay flue block system

INSTALLER GUIDE

4.7 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.
4.8 If the fireplace opening is an underfloor draught type, it must be sealed to stop
any draughts.
4.9 The appliance must be mounted behind a non-combustible hearth unless the
conditions of section 4.2.1.1 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.
4.10 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. The fireplace floor should be reasonably flat to
ensure that a good seal with the convection box can be made.
4.11 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.
4.12 This appliance must not be installed in any room that contains a bath or shower
or where steam is regularly present.
4.13 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.
4.14 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.

INSTALLER GUIDE

4.15 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.
4.16 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 = 700mm.
• For a shelf deeper than 150mm: 700mm + 12.5mm for every 25mm depth over
150mm (See Graph 1).

4.17 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.
4.18 A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, the infirm and pet animals.
4.19 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.
4.20 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.
A 10mm access clearance from a non-combustible surface is necessary at the left
side.

6. FIREPLACE CHECK
6.1 Fireplace check.
6.1.1 Fireplace size.
The fireplace must comply with the requirements described in section 4.2. This will
probably entail removing the fireback and infill material behind the fireback. The debris
catchment area shown in figure 7 must be kept clear of obstructions.
6.1.2 Fireplace general condition.
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. 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. 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.
6.1.3 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 10 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
Figure 7. Fireplace area.

INSTALLER GUIDE
Page 19
© Baxi Heating U.K. Limited 2008.
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.
6.1.4 Installations using a metal flue box
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 2).
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 non-combustible hearth. The hearth
material must be at least 12mm thick.
6.2 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.
7. IGNITION CHECK
Before attempting to install, it is worth checking that the electronic ignition system
performs satisfactorily.
Fit the battery to the ignition block located below the
burner tray at the left side (See figure 8). The positive
terminal (+) is to the bottom as you insert.
Depress the slider knob as far as it will go and hold in
this position. This should close the ignition circuit and
sparks should be seen tracking from the electrode pin
to the pilot tip (See figure 9).
If there are no sparks make the following checks.
 Check condition of battery and that it is correctly
fitted.
 If the above is satisfactory, check the ignition
circuit and components - see the servicing section in
this guide.
Figure 9. Slider control
Figure 8. Fitting the battery

INSTALLER GUIDE

8. GAS SUPPLY CONNECTION
A nut and olive are provided for an 8mm pipe inlet connection to the ‘T’ connector at
the bottom front of the appliance. The ‘T’ connector can be rotated to allow a
connection from any direction and 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 convection box and run to the ‘T’
connector at the front. The pipe run from the supply line up to the rear opening in the
convection box must be kept away from the area which will be taken by the
convection box when it is installed (See figure 7).
Note that the centre of the appliance inlet ‘T’ connector is 25mm above the fireplace
floor. The inlet ‘T’ connector should be fitted to the supply pipe at this stage.
9. PREPARING APPLIANCE FOR INSTALLATION
IMPORTANT
Before continuing with the installation of this gas fire the aeration setting on the
burner must be checked. The aeration is factory set and should not require
adjustment. See section 17.1 (Servicing and parts replacement).
1. Unscrew and remove the knurled screw
connecting the slider control arm to the burner
module. Lift the slider control knob, moving the
control arm away from the burner module.
2. Unscrew and remove the six screws that secure
the window mounting frame and window assembly.
Remove and place away from the work area. (See
figure 10).
3. Detach the burner unit from the convection box by
removing two screws (See figure 11). Lift the burner
unit clear.
