INSTALLER GUIDE

1. SAFETY
Installer
Before continuing any further with the installation of this appliance please read the
following guide to manual handling:
The lifting weight of the appliance is 26.2 kg.
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 gaskets 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.

4.2 Ventilation requirements.
No special ventilation bricks or vents into the room containing the appliance are
required.
4.3 Fireguard requirements.
A fireguard complying with BS 8423 should be fitted for the protection of young
children, the elderly, the infirm and pet animals.
Although this fire conforms to all the applicable standards, it is a heating appliance
and certain parts of its surface will become hot.
4.4 Room considerations.
It is advisable that combustible fabrics such as curtains are not fitted above the fire. If,
however, this is unavoidable, a clearance of at least 150mm must be maintained from
the extreme bottom edge of the fabric to the extreme top surface of the fire.
4.5 The hearth.
The appliance can be installed with or without a non-combustible hearth. If a non-
combustible hearth is installed, there must be a minimum clearance from the top
surface of the hearth to the absolute bottom of the appliance of 18mm (See figure 1).
The hearth must be at least 700mm wide x 300mm deep. The non-combustible
hearth material must be at least 12mm thick. Its top surface should be preferably
50mm above floor level to discourage the placing of carpets or rugs over it. If the
appliance is not installed with a hearth meeting the above conditions, the minimum
distance from the top surface of the finished floor covering (including any carpet etc.)
to the absolute bottom of the appliance must be at least 40mm (See figure 1).
Page 10

Figure 1. Dimensions
INSTALLER GUIDE

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 finished floor level should be increased to at least 115mm.
4.6 Fireplace clearances (See figure 2).
4.6.1 The minimum height from the extreme top surface of the fire to the underside of
any shelf made from wood or other combustible materials is as follows:
For a shelf up to 150mm deep
Minimum height from the extreme top surface of the fire = 150mm.
For a shelf deeper than 150mm
150mm + 12.5mm for every 25mm depth over 150mm.
There is no restriction on the depth of non-combustible projections but a space of at
least 30mm should be allowed above the top of the appliance to enable removal of
the fascia.
4.6.2.1 For combustible projections up to a depth of 178mm (Measured from the
rear fixing plane of the fire) a minimum clearance of 75mm should be maintained at
the left and right side of the fire. This is measured from the extreme side of the fascia.
This will allow easy access to the control knob and knurled nuts for removal of the
fascia. This clearance is mandatory for temperature requirements.
4.6.2.2 For any combustible projections beyond 178mm (Measured from the rear
fixing plane of the fire) a minimum clearance of 100mm should be maintained at the
left and right side of the fire. This is measured from the extreme side of the fascia.
This clearance is mandatory for temperature requirements.
4.6.2.3 For non-combustible projections a minimum clearance of 75mm should be
maintained at the left and right side of the fire. This is measured from the extreme
side of the fascia. This will allow easy access to the control knob and knurled nuts for

removal of the fascia.
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.
4.7 Wall thickness and material.
Wall thickness:
Minimum wall thickness 102mm (4in.).
Maximum wall thickness 660mm (26in.).
This fire is suitable for use with combustible walls provided that there is no
combustible material or combustible cladding in the area indicated on the wall fixing
template.
Please note that soft wall coverings (e.g. embossed vinyls etc.) are easily affected by
heat. They may therefore, scorch or become discoloured when close to a heating
appliance. Please bear this in mind when installing.
4.8 Flue hole size and location.
A hole 152mm (6in) is required through the wall for the flue unit.
The minimum height of the hole centre is shown in figure 1 and on the wall fixing
template.
Minimum allowable distances from the terminal are shown figure 3.
4.9 Flue terminal guard.
In England and Wales the Building Regulations require a terminal guard to be fitted if
the terminal could come into contact with people near the building or be subject to
damage.
Fitting a terminal guard is recommended where contact with or damage to the
terminal is possible even if regulations do not demand it.
A suitable guard - Part No. 516539 - is available.

6. PREPARING THE FIRE
 Stand the fire upright.
 Detach the fascia by removing the knurled nuts
and washers at the fascia sides (See figure 1).
 Pull the bottom of the fascia forward and then lift
to remove.
 Remove the window unit by detaching the 12
wing nuts securing the window frame and pulling
forward (See figure 5).
7. PREPARING THE WALL
7.1 Preparation
The flue must be installed so that it is at right angles to the back panel of the fire all
round the flue circumference. The fire itself should be fitted vertically against a flat
wall. Where this is difficult to achieve due to building inaccuracies care should be
taken to ensure that the back of the fire is not stressed in any way due to distortion of
the assembly when tightening the fixing screws. Where necessary, non-combustible
packing pieces should be used to provide a satisfactory fixing surface. Before cutting
the hole in the wall make sure that the
height to the top surface of the finished
floor is known. The minimum acceptable
height from this surface to the flue hole
centre is shown in figure 6.
If a loose hearth or plinth is to be used,
the height from its top surface must be
used when determining the minimum flue
height. Where installation is to a timber
frame wall, the appliance should be
positioned so that the right side wall
fixings are into timber studs to absorb any
pressure generated by operating the
control knob.
Proprietary cavity fixings should be used
at the left side if the fixing at this side is

into plasterboard.
 Place dust sheets on the floor and over any furnishings etc.
 Place the template against the wall. Make sure that the centre of the flue hole is
not less than the minimum shown in figure 6.
 Pierce the centre of the screw fixing holes and the flue hole and mark the
positions on the wall. Remove the template.
 Cut the hole for the flue
unit. Make sure that it is
straight and level. Though a
hammer and chisel can be
used, using a core drill is by
far the quickest and simplest
method for normal brickwork.
7.2 Core Drilling
 Drill a pilot hole through
the wall. Inspect the hole to
ensure that it is in the
brickwork and not in mortar. If
it is in mortar, it is advisable to
reposition the hole
approximately 25mm away
(making sure that the
minimum side clearances and
height are complied with).
Remember to reposition the
screw fixing holes.
 Drill the flue hole with a 6in. (152mm) core drill. Where practical, it is
recommended that the hole is drilled from inside the building to about half the wall
depth with the remainder drilled from outside. This ensures that the edges of the hole
are clean on both sides.
7.3 Hammer & Chisel Cutting
 Mark a 152mm (6in) diameter circle for the flue hole. Chisel out the area marked.
 It may be necessary to make good both the internal and external wall faces. To
achieve a neat finish and to make any future removal of the flue unit easier, it is
recommended that a cardboard cylinder is formed around the flue unit and inserted in
the hole while making good. Remove the cardboard cylinder after making good.
 Recheck the screw fixing holes relative to the flue hole.
 Drill the four fixing holes to a minimum depth of 42mm using a suitably sized
masonry drill for the wall plugs supplied.
 Insert the four wall plugs supplied.
 Remove any combustible wall cladding material from the area shown in figure 7.
Page 16

Figure 7. Removal of combustible cladding.
INSTALLER GUIDE

7.4 Leaving a Hole, Building under Construction
It will be convenient to use a non-corrosive metal tube 160mm diameter built into the
wall at the correct position for the flue unit.
7.5 Combustible Walls (Wood, Fibreboard, Plasterboard etc.)
Building regulations require that the inlet and outlet ducts and terminal bust not be
closer than 25mm to combustible material.
 If the heater is to be mounted on to a plasterboard wall that has a wooden frame
behind it then the integrity and ability of the wall to carry the weight of the appliance
must be confirmed. It is important that any vapour control barrier is not damaged, and
that the structural members of the house are not damaged. We recommend a
minimum 12mm thick plasterboard.
 Mark out and cut a hole 202mm diameter through the combustible part of the wall.
A 152mm diameter hole can be cut through non-combustible parts of the wall. A
152mm diameter hole can be cut through non-combustible parts of the wall (See
figure 8).

INSTALLER GUIDE
Figure 8. Timber frame wall preparation.

Page 18
© Baxi Heating U.K. Limited 2010.
 Cover the hole with a square sheet
steel plate 500mm x 235mm with a
152mm diameter hole cut out of the
centre (See figure 9). The steel should
be not less than 1.5mm thick. Fix with
suitable screws and plugs.
 Where the whole wall is of
combustible material, a non-corrosive
plate 455mm x 455mm with a 152mm
diameter hole in the centre must be
fitted to the outer wall. The hole
through the wall should be lined with a
non-corrosive metal tube 202mm
diameter.
Cut the Flue Hole -Timber Frame
Buildings
Drill the pilot hole and hole in the outer wall as section 7.5.
 Since the flue will pass through combustible material in the inner leaf of the wall, a
non-combustible sleeve 203mm (8in.) diameter will be required round the flue (See
figure 8).
 Cut a hole through the inner leaf to accommodate a non-combustible sleeve
203mm (8in.) outside diameter. To minimise the effect of breaking through the vapour
control layer (VCL), if possible, cut the hole approximately 10mm undersize so that
the sleeve will be forced through the layer. A recommended technique for cutting the
inner leaf is shown in figure 9.
 Fit the non-combustible sleeve to the inner leaf. The sleeve must extend to be at
least flush with the breather membrane / timber sheathing but must not protrude more
than 10mm into the cavity.
 The annular gap between the flue unit and the sleeve must be sealed to prevent
air heat and moisture passing along it.
INSTALLER GUIDE
Figure 9. Wall cover plate.

8. PREPARING THE FLUE UNIT
 Measure the total wall thickness
from the outside surface to the inside
face. Add 80mm to this measurement
to obtain the correct length of flue unit
required.
 Mark off the flue length on the
outer (air) tube measuring from the
end of the terminal.
 Insert the polystyrene ring between
the inner and outer tubes to support
them and cut both tubes squarely at
the marked distance.
 Important: Remove all polystyrene
from the flue unit after cutting.

traditional brick built wall.
INSTALLER GUIDE
Figure 11. Flue unit installation into timber framed buildings.

 Fit the flue unit tubes firmly over the
spigots at the rear of the fire. Make sure that
the seam on the flue tube is NOT at the
bottom. Push on until the outer tube touches
the screw heads on the outer spigot (See
figure 12).
 If it is felt of benefit, the flue unit may be
additionally secured to the fire with one or
two suitable self tapping screws (we suggest
No.6) before installing into the wall as
follows:-
 Using a suitable metal cutting drill bit, drill
through the outer flue tube and outer spigot
at a distance of between 6mm & 7mm from
the cut end of the outer flue tube (See figure
12).
 Fit the self tapping screw(s) in the drilled
hole(s).
 Seal the flue unit all round the
circumference of the fire spigot with the tape
supplied.
 Insert the plugs into the wall fixing holes. Insert the top right fixing screw leaving
the plain shank proud to allow the top fixing keyhole in the fire back to go over the
screw.
 Offer the fire complete with flue unit through the wall and hook the top right
keyhole slot over the previously fitted wall screw.
 Insert the top left and two bottom fixing screws and tighten.
 Seal, the outer flue tube to the outside surface of the wall with fireclay or cement.
Make sure that the slots in the flue terminal are not closer than 8mm to the wall
and are not obstructed by cement.
