1. 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 of this heat engine and convection box is 7.4 kg.
One person should be sufficient to lift the heat engine and convection box. 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 a burner compartment rear wall
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
licenced to accept such waste. Protective clothing is not required when
handling these articles, but we recommend the use of suitable gloves to
prevent irritation. We also 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.

3.3 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.
3.4 Fireguard requirements.
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, the infirm and pet animals.
3.5 Room considerations.
3.5.1 This appliance must not be installed in any room that contains a bath or shower
or where steam is regularly present.
3.5.2 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.
3.5.3 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.
3.6 Chimney preparation.
3.6.1 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.
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.
INSTALLER GUIDE
© Baxi Heating U.K. Limited 2010. Page 11

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 2). 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 and surround.
The appliance must be mounted behind a non-combustible hearth (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 (See figure 4).
3.9 Fireplace clearances.
3.9.1 The minimum allowable distance from the outside of the fascia to a corner wall
having combustible material or any other combustible surface which projects beyond
the front of the appliance is 100mm.
For access purposes a 10mm clearance to non-combustible surfaces is
recommended on the left and right side of the appliance.
3.9.2 The minimum height from the top surface of the hearth 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 3).

3.10 Installation options.
In the United Kingdom, as supplied, the appliance can be installed in the following
situations: -
3.10.1 Conventional fireplace and hearth.
To a fireplace complete with hearth as shown in figure 4. Chair brick removal may not
be required providing at least 50mm clearance is available from the flue outlet to any
fireplace component.

3.10.1.1 ‘Hole-in-the-wall’ installations
It is recommended that a hearth should be installed as in section 3.8 (See figure
4).
If fitting a fascia that has a fire front designed to sit on a hearth, a reduced depth
hearth is recommended. The recommended reduced hearth depth is 100mm, this
is necessary to support the fire front. The heat engine must be installed so that
distance from the base of the fireplace opening in the wall to the finished floor
level shall be at least 72mm. 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, then the distance from
the base of the fireplace opening in the wall to the finished floor level should be
increased to at least 147mm.
If fitting a fascia that does not have a separate fire front and a hearth is not fitted,
the heat engine must be installed so that distance from the base of the fireplace
opening in the wall to the finished floor level shall be at least 72mm. 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, then the distance from the base of the fireplace opening in the wall
to the finished floor level should be increased to at least 147mm.
To protect from the risk of burns and ignition of clothing a tactile separator shall be
used. The hearth detailed in section 3.8 meets the requirements for a tactile
separator. If this is not used then a 625mm 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.
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 5.
The top surface of the metal flue box must
be covered with a 50mm layer of mineral
wool or equivalent insulation (See figure 5).
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.
INSTALLER GUIDE
Figure 5. Metal flue box

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 BS1289 or BS EN 1858 with dimensions as in figure 6.
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.
The appliance is suitable for installations conforming to older versions of BS1289 as
well as the current edition. The flue blocks must have a minimum width (Depth
looking from the front of the fireplace) not less than 63mm and a cross-sectional area
not less than 13,000mm2. Older editions of BS1289 required a cross-sectional area
of 13,000mm2. The current revision of the standard requires 16,500mm2. This
appliance is suitable in both cases. The total depth of the opening measured from the
finished front of the fireplace (Including plaster, surround etc.) must be as below:
If the width at the rear of the
precast flue starter blocks is 300mm
or greater the depth of the opening
is to be not less than 138mm. Under
these conditions the eyebolts will
need to be located as close to the
sides of the starter blocks as
possible.
If the width at the rear of the
precast flue starter blocks is less
than 300mm then an additional
16mm of depth will be required to
accommodate the eye bolts.
Therefore if the starter blocks are
less than 300mm wide the minimum
depth of the opening will be not less
than 154mm.

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.
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.
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.
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 3.10.3
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 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. The flue must be completely sealed so that combustion products do not come into
contact with combustible materials outside the chimney.
3.12 Propane gas fires.
Propane gas appliances must not be installed in a room, which is built entirely below
ground level (See BS 5871 Pt2).

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 guide. 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
INSTALLER GUIDE
Figure 7. Pack contents

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 area at the back is sound enough to take
the eyebolts. 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.
6. IGNITION CHECK
Before attempting to install, it is worth checking that the ignition system performs
satisfactorily.
 Set the control knob to the OFF position.
 Depress the control knob and rotate it anticlockwise
to the PILOT / IGN position. A 'click' will be heard as the
integral piezo operates. A spark should be seen between
the electrode and pilot tip. If there is no spark check the
following: -
 Ensure that the electrode lead is connected to the
terminal at the base of the electrode.
 If the above is correct, check for damage to the
electrode lead.

7. GAS SUPPLY CONNECTION
A nut and olive are provided for an 8mm pipe inlet connection to the inlet ‘T’
connector at the bottom front of the appliance. The inlet ‘T’ connector can be rotated
to allow a connection from any direction. The inlet ‘T’ connector 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
inlet ‘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. 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.
8. PREPARING APPLIANCE FOR INSTALLATION
8.1 Appliance preparation.
1. Remove any transit tape and packing and inspect for any evidence of mishandling
which might affect the performance. Each unit is flame tested before it leaves the
factory and as a result there may be slight discolouration around the burner ports.
2. Detach the burner unit from the convection box by removing two screws (See
figure 9). Lift the burner unit clear.
3. It is important that the grommet supplied in the loose parts pack is fitted to
the hole in the rear of the convection box (See figure 10).
