*The inlet pressure must be within +/- 1mBar of specification with all gas appliances in the house

switched on and also with just the Burley heater operating. If outside of this tolerance the fault is
most likely to be in the installation pipe work or service governor at the meter. If the problem is
the meter governor, this is the property of the gas service provider (such as Transco / National
Grid 0800 111999 or Bord Gais) and they should be called to rectify this. The fire will not operate
correctly if the pressures are incorrect.

2. UNPACKING THE APPLIANCE

2.1 Carefully examine the carton for damage before unpacking. If it is obviously damaged,

consult the supplier as to whether to proceed with the installation.

2.2 Make sure the carton is stood upright and open the top.

2.3 Remove the fittings boxes contained within and open them and check the condition of the

contents. Remove the fire and examine its general condition, paying particular attention
to the frame, the glass front and fire box flanges.

2.4 If satisfied by the general condition, place the decorative components to one side and
proceed with the installation. If in any doubt, seek advice from the supplier. Read these

instructions fully before proceeding even if you have fitted this model before.

GENERAL REQUIREMENTS

3.1 Gas appliances must be installed in accordance with the rules in force. In the UK it is the

law that all gas appliances must be installed by a Gas Safe™ registered installer (formerly
CORGI), in accordance with the Gas Safety (Installation and Use) regulations (as
amended). The installation must also be in accordance with the relevant parts of local and
national building regulations and in accordance with BS5871 pt4 except where Burley
instruction state differently. For the Republic of Ireland, reference should be made to
IS813 and ICP3 and any guidance notes from Bord Gais. Failure to have the fire fitted by a
qualified person nullifies ALL guarantees.

3.2 The space to be heated must have a wall vent of at least 100cm² of ventilation and an
openable window or patio door that communicates directly to the outside. The vent must
be positioned at least 1 metre away from the appliance, in the Republic of Ireland two
vents of not less than 60cm² each, one not less than 1.6m above the other, must be
installed in the room. With the minimum size room and with the ventilation specified, the
concentration of NO2 in the room will be less than 150ppb.

3.3 When providing ventilator openings consideration must be given to the avoidance of
locations where discomfort from draughts may cause the user to block the openings.
Similarly the possibility of curtains or furniture blocking ventilation openings must be
considered. Floor vents, ceiling vents, closable window vents or chimneys are not

suitable means of ventilation.

3.4 Working surfaces include the air outlet grille.

3.5 The heater must not be used in a room of less than 50m³ in volume. Adjoining spaces, not

separated by a door may be included. To convert cubic feet (ft³) to cubic metre (m³)
divide the room volume in cubic feet by 35.3.

3.6 The heater must not be installed in high rise blocks of flats (unless a gas supply already
exists), bed sitting rooms, basements which are not open on at least one side, bathrooms,
or bedrooms, in corridors stairways landing or hallways of multi occupancy dwellings,
garages or rooms containing petroleum products.

3.7 Soft furnishings, decorations and wall coverings etc. must not be placed within 1 metre of
the appliance and its convection outlets (see 5.0). Be aware of curtains etc which could be
blown towards the appliance.

3.8 The heater is intended as a secondary heat source. Check that a primary source of heat
(such as radiators) is present in the room. If insufficient primary heat is being used there
may be a build up of condensation, if this is the case, please warn the customer of this.

3.9 The heater must not be used in rooms where the atmosphere is likely to contain water or
chemical vapours which may adversely affect the appliance or its finish.

3.10 Do not use whilst painting & decorating, or in newly decorated rooms as the residues can
lead to unpleasant smells from the appliance. Always cover or have the appliance
removed when decorating. (See points to note on page 14)

3.11 Candles too close to the fire may melt. Scented candles must be at least 1 metre away
from the appliance.

3.12 Air freshener residues can enter the appliance and lead to residual odours, especially the
plug in type.

3.13 The catalyst is not an air cleaner and presence of odours is unlikely to be catalyst failure.

3.14 Houses with warm air heating systems, solid walls, or no damp proof course may be

unsuitable for Flueless appliances.

3.15 This heater does not contain asbestos.

3.16 The oxy pilot can become blocked by fibres from new carpets and pet hairs advise the

customer to vacuum around the pilot on a regular basis to prevent blockage to pilot unit.

INSTALLATION INSTRUCTIONS

Before working on pipe work, plug the ends to prevent the entry of debris. Decide upon the

route for the gas and lay pipes as required. Where pipes pass through walls they must be
sleeved.
Before connecting any pipes to the appliance, fully purge pipes of debris or swarf etc. and
connect the gas supply to the 8mm elbow on the fire. Leak test the supply using an approved
method. Fires can be connected to the supply using semi rigid pipe i.e. copper tube also
independently certified, hand bendable corrugated stainless steel connection pipe (such as
Forma Pipe ™) may be used with this appliance
Note: An isolating valve must be situated near the appliance for servicing.

THE APPLIANCE IS NOT TO BE RECESSED INTO THE WALL FOR SAFETY AND OPERATIONAL REASONS

4.1 The appliance is a flueless visual flame heater designed to be installed on to a flat wall. It
MUST NOT BE INSET INTO THE WALL as this could block the inlet and outlet passageways

from the fire leading to a hazard. The wall on which the appliance is to fix must be upright
and flat. Failure to observe this could result in the appliance becoming twisted or
damaged.

4.2 If the appliance is to be mounted on a dry lined or a timber framed construction wall then
the integrity and ability of the wall to carry the weight of the appliance must be
confirmed. It is important in these circumstances that any vapour control barrier is not
damaged, and that any structural members of the house frame are not damaged.

4.3 Care should be taken with wall coverings as heat may discolour them over time.

4.4 Any combustible materials directly behind the must be removed and replaced with

suitable non combustible material such as supalux board, calcium silicate, cement or
similar. Only the frame supplied with the appliance must be used. Any other type could
become damaged, effect combustion or overheat the gas controls.

4.5 The appliance is designed to be wall mounted alone and not in conjunction with any type
of combustible fire surround.

4.6 If an existing fireplace or flue is in the wall behind or adjacent to where the fire will be
fitted, it MUST be blocked off completely to prevent suction on the back of the appliance.
The top of the flue should also be capped off to prevent the entry of moisture etc, consult
building control if in any doubt.

5. CLEARANCES TO COMBUSTIBLE MATERIALS AND SHELVES

5.1 A non combustible shelf with projection less than 100mm may be fitted to within 500mm

of the top edge of the fire frame. Note that shelves will get hot and delicate ornaments,
wax candles etc should be kept away from hot surfaces. No combustible shelves should
be fitted for at least 1 metre above the appliance and a similar clearance should be
maintained to ceilings.

5.2 As with all heaters the possibility of convection staining on surfaces in the vicinity of the
heater shall be considered and the user advised. Particular attention should be taken to
ensure soft furnishings such as scatter rugs and curtains are kept at least 1 metre from
the appliance.

5.3 On no account should glass mirrors or picture frames or any electrical equipment e.g.
plasma screen TV’s be fitted or positioned on the wall above the appliance as the heat
rising could damage them.

5.4 The user shall be advised when relevant that hot convection air from the grille outlet
induces the possibility of staining on surfaces in the vicinity of the appliance. This can be
caused by the effect of heat on the finish and also burned dust & tobacco particles etc.
being carried in the convection currents of the fire. Particular attention should be taken
to ensure soft furnishings such as soft cushions and curtains are kept at least 1 meter
from the appliance. Blown vinyl and flock and embossed wallpapers can be scorch
damaged by being too close to a heat source and may discolour over a period of time.

6. PREPARING THE APPLIANCE

6.1 Unpack the heater.

6.2 Ensure appliance is correctly marked for the gas it is to be used with. Take the appliance

components and lay them out in an ordered manner. To prevent damage the decorative
frame and fire bed components can be placed safely to one side. Note how the frame
attaches to the fire.

6.3 DO NOT ATTEMPT TO USE THE APPLIANCE WITH BROKEN/DAMAGED COMPONENTS.
Contact our service department 01572 756956

6.4 Decide upon the route for the gas supply and if this is to be a concealed supply, select a
suitable hole in the fire box, remove the knockout and lay in the supply as required. Note
the supply can be either concealed through the holes in the appliance back or surface
fitted but where pipes pass through walls they must be sleeved. If the gas pipe passes
through a wall, cavity or un-vented void then there should be no joins in this area and the
pipes should be fully sleeved preferably in factory sleeved pipe. Before pushing gas pipes
through walls, seal the pipe ends to prevent debris entering the pipes.

6.5 The fire must be mounted minimum 200mm from floor level

6.6 Hang the appliance on the wall and fix into position.

6.7 Fully purge pipes of air and any debris and connect the gas supply to the 8mm isolation

elbow supplied with the fire. Leak test the supply using an approved method.

7. REMOVING AND REFITTING GLASS & DECORATIVE TRIM

7.1 To remove the glass, remove the decorative trim and then the 4 screws in the side frames

and pivoting it out from the bottom then remove glass from its top channel. Refitting is
done in reverse order.

A bag of loose chippings is supplied for fitting in the appliance, if desired they can be
distributed in the chippings trays to the front and rear of the burner outlet. Chippings
should be evenly distributed and it is very important that on no account should the
chippings obstruct the burner outlet, flame paths or pilot burner. Always replace the glass
after laying the chippings. Do not attempt to use the unit with broken / damaged glass

Do not use additional or non-standard chippings, coals, logs etc.

10. COMMISSIONING

10.1 TEST THE GAS PRESSURE. Turn the fire on full, attach a manometer to the inlet test point

and ensure there is a pressure of 20mbar (+/- 1mbar) for natural gas appliances or
37mbar for propane appliances. Now turn on every other gas appliance in the house and
re-check the pressure. The pressure must still be within the tolerance of +/- 1mbar. Now
turn off all the other gas appliances and turn the fire down to pilot only, the pressure
must still be within the tolerance of +/- 1mbar. If it is not TRANSCO, BORD GAIS or the gas
supplier must be called to adjust the governor to the house before the fire can be
commissioned further. Call outs to fires with incorrect pressures will be chargeable.

10.2 Brief the customer on the operation of the appliance and give them all the instructions.

The customer must be told of the need for regular servicing of the appliance, this will be
at least once a year and be made aware that no rubbish is to be thrown onto the fire bed.
The customer must also be made aware that purpose provided ventilation should be
checked regularly and not be blocked.

10.3 If you have any questions or the fire is not operating correctly, phone the Burley help-

line BEFORE you leave the installation.

If the appliance is not fitted in strict accordance with these instructions, Burley cannot
be held responsible for any damage caused and reserve the right to charge for any
corrective work. Double check standing and working pressures and securely seal all
relevant open chimneys and flues.

10.4 Oxygen Depletion Pilot System There is a highly sensitive oxygen depletion sensor

designed into the pilot light and may not light first time or may extinguish after a few
minutes, please advise the customer of this. If any part of the OXY Pilot is damaged the
entire unit must be replaced. Do not attempt to bend or alter the flame head,
thermocouple or aeration hole. Use only genuine spare parts as similar looking parts from
other appliances may well give different or inferior performance and could lead to a
hazard.

10.5 Fireguards A fireguard is not supplied with this appliance and being wall mounted, the

need for one will have to be assessed depending on the position, height from ground of
the fire; however it is recommended that a fireguard to BS8423 is fitted if the fire is to be
used in the presence of young children, the elderly and the infirm.

10.6 Completion of Warranty Card. The installer section of the guarantee card must be filled

in fully to validate the warranty. I.e. pressure, model, room size and Gas Safe™
registered installer (formerly CORGI) number

11. SERVICING INSTRUCTIONS

As with all gas appliances the unit must be serviced at least once per year, preferably at
the beginning of the heating season. All servicing must be carried out by a qualified
service person.

Before commencing any servicing, ensure that the gas is turned off to the appliance and
that the appliance is cool.

Cleaning – If required the casing should be wiped with a cloth dampened in soapy water.
The glass may be cleaned with any non-abrasive cleaner such as ‘hob brite‘.

Unscrew the decorative frame to remove. Unscrew the four screws holding the glass,
remove and place thoughtfully to avoid damage or injury.

Carefully remove the loose chippings and remove any dirt with a soft brush (paint brush)
and clean the burner and associated parts using a vacuum cleaner. Take particular care to
remove all debris around the pilot light.

We recommend the use of a HEPA filtered vacuum to remove any dust and soot
accumulated in the heater before and after working on it. Normal hygiene rules of not
smoking, eating or drinking in the work area should be followed.

Disconnect the gas supply to the appliance.
Clean around all air inlet grills removing all lint in the area of the injector and ensuring the

pilot light aeration hole and flame head are clean. Injectors – Only original manufacturer’s
injectors must be used, see section 1 for identification. Should the oxypilot system need
to be replaced, the original manufacturer’s parts must be used.

Controls – The GAS CONTROL IS FACTORY SET AND NORMALLY NEEDS NO ADJUSTMENT.
Check for smooth operation of the gas valve. Remove access cover & check the tightness
of the thermocouple connection into the valve and test ignition leads.

Examine the fire casing, the firebox and catalytic converters for obvious signs of damage
or degradation. Clean out any dirt or dust accumulated in the bottom of the fire.
Reassemble in reverse order.

Test all joints for leaks.
Following the instructions, re-lay the chippings (if used) and replace the glass.
Light the fire using the method in the instructions and ensure that the pilot lights

consistently and the pilot flame envelopes the thermocouple. The pilot should hold in
after approximately 10 seconds & turn the main burner on, this should light smoothly
within 10 seconds. Ensure the valve turns down by double clicking the low flame button.
The gas manifold pressures are factory preset using highly accurate equipment and do not
normally need adjustment.

Run appliance for 15 minutes, ensuring burner flames settle evenly.
A combustion analysis check should then be carried out. Using an analyser to BS7927, first

zero the equipment and sample the entire width of the combustion product outlet. Ratio
of CO/CO2 should be less than 0.002 within 30 minutes. (20ppm CO per 1% CO2) A
reading of CO in the room centre should give a rise of less than 9ppm over ambient, peak
reading. The catalyst is unlikely to need replacement during the life of the heater but if
the combustion is suspect, disconnect the appliance and contact the manufacturer.

13. Flue Gas Analysers – Installation & Servicing Facts

• Please read this sheet even if you have fitted our fires before.

• Please leave this sheet with the customer as reference for future servicing of the

appliance.

• Please explain to the customer how the fire works and the details and facts listed on this
sheet, particularly what the catalyst does and doesn’t do.

• If you have any doubts about the test procedure please visit our website or call our
technical help line

Testing – Points to note…

• Before testing ensure that the minimum room size is correct for the heat output of the
fire. 30m³ for 2.5kw output, 40m³ for 3.5kw and 50m³ for 4.5kw.

• In all installations regardless of room size there must be an air vent positioned at least
one metre from the fire at either high or low level through an outside wall providing
100cm² of free air. (For the Republic of Ireland 2 vents of not less than 60cm² must be
provided at high and low level, with minimum vertical separation of 1.6m).

• The analyser used must be manufactured to BS7967 and the test must be carried out in
accordance with BS5871 Pt 4

• The catalytic converter needs heat to work, therefore before you start testing; the fire
must have been lit and burning on full for at least 15 mins.

There are two tests to carry out. A Co / CO² ratio test and a room centre CO test.

1. The first test is the CO / CO² ratio test and should be carried out at the fire outlet grille, do
not stick the probe of the analyser in through the grill but move the probe back and forth
1 inch on top of the outlet grill. You should record a ratio of no more than 0.002 %
(20ppm CO to 1% Co²). It is advisable to have a high sample of CO² as this will improve the
test. If you have less than 1.0% CO2 the analyzer may give false results due to the
accuracy of analysers reducing at low CO2 levels.

2. The second test is the room centre CO test. You should stand in the room centre with the
probe at waist height and read the level of CO; this should be no more than 9ppm over
ambient peak. Please record these readings on the customers guarantee card.

Our Flueless fires also contain the following safety devices an ODS (Oxygen Depletion Sensor) and
FSD (Flame Supervision Device). Point out to the customer that unfortunately these are not
found on all gas hobs; which are also flueless devices)

Page 14 of 20

14. Points to Note Regarding the Catalytic Convertor!

• If the customer smokes tobacco products, lives on a busy road or is cooking with a gas
oven/hob at the time of testing you must ensure that an ambient CO reading is taken
before lighting the fire and attempting a reading.

• Does the catalytic convertor need replacing? The catalytic convertor does not need
replacing unless it has become physically broken or the combustion test shows
deterioration in performance over time. To constantly test the performance of the
catalytic converter, our laboratory has been running appliances eight hours per day, five
days per week, for up to seven years. Periodically we send catalytic converters back to the
manufacturer for testing. After the equivalent of 30 years of use, the catalytic converter is
as efficient as it was when brand new. Burley manages to achieve this by designing the
fire to ensure that the catalytic converter is in exactly the right position for long life and
maximum efficiency. (For other makes of fire please consult the relevant manufacturer).
Only use replacement catalyst supplied by Burley.

• If you or the customer detects any odours from the fire please remember that the
catalytic convertor is not an air filter and does not remove smells. The ceramics in the fire
can absorb household smells and in turn these smells get emitted when the fire is lit,
especially if the fire is used in an enclosed space for a period of time. If this is the case we
recommend that the fire is run on maximum for at least 5 hours with the doors and
windows open. This should be done at least twice a year, preferably in the spring and
autumn or at any time they notice a smell.

• We do not advise the burning of wax candles within 1 metre of the fire. Wax particles can
become airborne and deposit and solidify in the fire causing potential combustion
problems.

• The catalyst can also be affected by airborne paint smells and vapours from some plug in
air fresheners. The fire must be removed or sealed if you plan to decorate anywhere in
the house. If you can detect smells from the fire carry out the burning off procedure as
above.

Further information regarding the catalytic convertor and Flueless fires in general can
be found on our website www.burley.co.uk

15. Gas rating of Burley Flueless Appliances

Burley’s Flueless Gas Appliances are all gas input rated in the factory and undergo further line tests for
combustion, sooting and visual performance. For Installers who wish to gas input rate appliances we need
to establish tolerances for pass and fail.

Manufacturers Tolerances

The Heat Input on appliances can be expressed as either a Nett or a Gross figure. When the installer is gas
rating from the meter they will be using gross heat input which is 10% higher than Nett. This conversion
has to be taken into account if the manufacturer has quoted a nett figure.
The manufacturer also has to account for production tolerances on pipes, injectors, valves etc and is
allowed a further +/-5% tolerance on the maximum rate.

Burn Down

Cold appliances generally allow a greater rate of gas to pass through them and once the appliance warms
the gas density alters and causes the rate to reduce to the figure stated. This is known as Burn Down.
Manufacturers carrying out their technical tests allow appliances to be fully warm and burn down before
taking readings and this is typically after 1 hour. Some appliance manufacturers quote a ‘cold’ figure for
the gas rate so that installers can measure this immediately.

Installer Tolerances

It is important to take a gas rate test over a reasonable period of time so that the capacity of the meter is
used. On low Input appliances such as our flueless this is even more critical because uncertainties can
creep in. It is worth measuring over a 5 minute period to make sure.
It is also important to get your inlet pressure to 20mBar.
In a gas appliance factory compensation is also made for variations in

• % Saturation of Gas

• Variation in Calorific Value

• Variation in Gas Density

• Gas Temperature

• Gas Pressure

• Atmospheric Pressure

• Meter Calibration

• Stopwatch Calibration.

In the home it is not possible to correct for these therefore an uncertainty factor needs to be built into all
measurements.
Currently Gas Safe™ (formerly CORGI) does not quote a figure on this uncertainty but the measured gas
rate could vary by +/-5%.

Conclusion

In adding all the variables together,

• an appliance quoting Gross Heat Input could be anything from +/-10% of the quoted heat input

• an appliance quoting Nett Heat Input could be anything from 0% to +20% of the quoted figure

when measured as a Gross figure.

• If the appliance is cold anything up to a further 10% error could be expected and we don’t quote
these figures because they change rapidly. The figures shown below are hot figures.
