INTRODUCTION
Than you for choosing this burley product. All of our products carry a CE mar which is awarded by
an independent test house (notified body) and shows the fires have been type tested to meet the
essential requirements of the European Gas Appliance Directive and the appropriate British
Standards.
This is a highly efficient Flueless Inset Live Fuel Effect Appliance. The burner system is very clean
burning and a catalyst cleans the combustion products even further.
A thermostat in the burner control system adjusts heat output to maintain a room temperature,
which can easily be set by the user. The appliance is operated via a battery powered remote control
system. Operation is also possible on the appliance with push button controls. There is also a
separate control to adjust the flame effect as required. Please demonstrate its operation to the
customer before leaving.
An oxygen depletion sensing pilot light is also fitted and will sense any significant oxygen depletion
in the room and shut the fire down safely.

Overall Dimensions
4 Hearths, loor protection and carpets
This appliance does not need a hearth and can be used on wooden, laminate floors and non-
combustible surfaces. It must not be placed directly onto carpets or rugs. Where the floor is
carpeted, the carpet must finish 100mm clear of the appliance legs and be fully removed
underneath. Loose rugs should be ept well away from the appliance (warn the customer of this).
Standing the appliance directly on a floor can lead to discolouration and / or drying out.
When a hearth is used, the top surface can be wood but be aware that heat can discolour certain
finishes over a period of time and can dry out poorly seasoned wood causing splitting. The hearth
should be 100mm larger than the appliance all round and minimum 12mm thic . Carpets can come
to the edge of the hearth.
5 Clearance to Walls
Rear Clearance - The rear of the appliance can be installed directly against a non combustible wall.
A distance of 50mm should be allowed to walls with wooden cladding, wallpaper, or finishes li ely
to be affected by heat.
Side Clearance - The sides of the appliance can be installed with 25mm of side clearance to non
combustible materials but this should be increased to 150mm for combustibles.
The fireplace and ALL materials including paints or lacquers must be rated for a minimum constant
temperature of 150°C. Any hearth or bac panel not meeting the above clearance dimensions must
be made from a non-combustible material such as marble or slate, although ‘lightweight’ and tiled
surrounds can be used provided they have a minimum heat rating of 150°C.

5.
Top Clearance - The heat from the appliance is concentrated towards the front edge directly above
the combustion products outlet. The clearances stated relate to a distance from the bac edge of
the stove.
A non combustible shelf may be fitted to within 50mm of the top edge of the fire. Combustible
material such as wood may be fitted to within 100mm of the sides of the firebox provided it
protrudes no further forward than 100mm.
Maximum depth of shelf 100mm 150mm 200mm
Minimum distance from 200mm 250mm 300mm
top of fire to underside of shelf
These distances should be doubled if the shelf is above the outlet grille.
6 Gas Supply
The gas supply should be installed in accordance with all regulations in force. Consideration should
be given to the routing to conceal from view and avoid potential damage. Pipes through walls
should be sleeved. The gas connection is 8mm compression and should be made in semi-rigid
tubing such as copper pipe. Before wor ing on pipe wor plug open ends. A servicing isolator is
supplied with the appliance and this should be used to permit disconnection for servicing etc.
All gas wor should be underta en by a competent person, see General Requirements.
7 Siting the Appliance
If the appliance is to be in or in front of an open fireplace, the chimney or flue MUST be bloc ed off
to prevent the draw from disrupting the flame pattern of the fire which can lead to poor
combustion or sooting. Extractor fans must be sited at least 2m from the appliance.
Chec the room has sufficient volume and ventilation; if these requirements cannot be met then
the appliance should not be installed. Consideration should be given to the requirements of other
appliances wor ing in the same room space. If other flueless appliances such as coo ers are in the
same room then consideration should be given to the combined room size requirement.
Chec the room has a bac ground heat source such as central heating radiators, storage heaters
etc.
Chec the appliance data plate details are correct for the ind of gas used and the country of
installation.
Carry out any building wor s such as ingle-noo s, hearths and recesses. If no hearth is being used,
remove any carpets to required clearance. Lay in the gas supply and leave a tail to connect to.
Position the appliance and ensure it is stable and unli ely to move in normal use. Some hearths can
be slippery and it is best to fix the appliance by removing the plugs in the plastic feet and screwing
down. Care should be ta en to ensure correct clearances around the stove.
Before connecting any pipes to the appliance, fully purge pipes of any debris or swarf etc.
Attach the gas connection to the stove and carry out a lea test in an approved manner.
Unclip the thermostat from the bac of the stove and by carefully extending the capillary tube
locate it in a place where it will sense room temperature. This is particularly important if the stove
is fitted in an ingle noo where the thermostat could give a misleading shut down unless it is
relocated to a cool location.
8 Laying the Coals G4220 - 4229 range
Opening the hinged door on the appliance, which is secured by a 10mm nut, gains access to the
coals. On no account should the appliance be operated whilst the door is open except for brief
periods during maintenance.
Do not lay the coals in any way other than that shown.

6.
9 Fitting back coal
Ta e the ceramic bac bloc and place into position as shown. The coal shapes should be facing you
and the base of the
coal locates behind
the tags on the
burner.
10 Fitting ront Coal
The front coal fits vertically between the burner and the front of the case as shown.
The coal sits with the 4 coal shapes uppermost and coal profile facing you. The feet on the front
coal locate between the burner and tags in the burner tray.
• Always secure the door closed after laying the fuel effects.
• Do not attempt to use any unit with bro en or damaged glass.
• Do not use the fire with bro en coals.
• Do not add any additional fuel elements to the fire.
• Do not use similar loo ing parts from other appliances,
• Use only genuine spare parts.
• Do not use the appliance for burning waste .

7.
11 Commissioning the Appliance
If the pipes have not been purged of debris do it before lighting the appliance. Failure to do so will
result in bloc ages within the burner and pilot.
Burley Appliances is the only company to bench
run and thoroughly test every single gas fire it
produces. Burley is in the unique position of
nowing that every appliance that leaves the
factory is in perfect wor ing order.
The installer should measure the inlet pressure
with the appliance running on high and ensure it
is to specification.
Attach a manometer to the inlet test point and ensure there is a pressure of 20mb (+/- 1mb) for
natural gas appliances or 37mB for propane appliances.
Now turn on every other gas appliance in the house and re-chec the pressure. The pressure must
still be within the tolerance of +/- 1mb.
Turn off all other gas appliances and turn the fire down to pilot only, the pressure must still be
within the tolerance of +/- 1mb.
If it is not TRANSCO or BORD GAIS must be called to adjust the regulator to the house before the
fire can be commissioned further.
Any large pressure fluctuation indicates pipe wor or governor problems and should be rectified.
Instruct the customer on the operation of the appliance and leave all instructions with them.
12 Lighting the Heater
There are 2 control nobs on the appliance. The left hand one (coloured red) controls On / Off and
High / Low flame. The right hand one (coloured blac ) is the comfort level thermostat, which turns
the fire to pilot position once the desired temperature is reached. Some people prefer to retain a
flame effect using the left hand nob to control its height whilst eeping the thermostat set on hot.
Others prefer to use the fire purely as a heater in which case they will select a flame height then set
the thermostat to a comfort level. In both cases if the room gets too hot, the thermostat will reduce
the fire to pilot setting.
If during use the pilot is alight but the main burner will not light, chec the thermostat position and
if necessary select a warmer setting.
To light the fire, press the left hand (red) control nob for several seconds then turn anticloc wise
to the ignition position. A clic will be heard and the pilot (under right side of fuel bed) should light.
If it does not light, repeat the operation a few times. Continue to hold nob for 15 – 20 sec's to
establish the pilot and then release. If pilot fails to establish, turn off, wait 1 minute then repeat
lighting procedure. Rotate the control nob to high flame to light then bac to the desired flame
position. If no gas comes through rotate the right nob (thermostat) to a hotter room setting and
the fire will light.
Control the fire by a combination of thermostat and / or flame setting to suit your mode of use.
To turn the fire off, rotate the left hand nob fully cloc wise.

13 Spark Failure
The gap between the pilot electrode and the pilot should be 3.5 – 4.5mm and normally adjustment
is not necessary. If the igniter fails a lighted taper can be inserted into the pilot area when
attempting to light the pilot and this should help the fire to light.
14 Thermostat
A room temperature thermostat is attached to the inlet gas pipe. It is set for a normal range of
operating temperatures but for more accurate monitoring of room temperature it is advised that
the sensing bulb is removed from its clip and carefully moved to a cooler location up to 1 metre
away, ta ing care not to brea or pinch the capillary tube.
15 Oxygen Depletion Pilot System
There is a highly sensitive oxygen depletion sensor designed into the pilot light. If any part is
damaged the entire unit must be replaced using only genuine spare parts as similar loo ing parts
from other appliances may well give inferior performance. If the fire repeatedly trips off in
operation the oxygen depletion system may be operating and a qualified engineer should
investigate this.
16 Instructing the Customer
The installer should instruct the customer on the operation of the appliance and handover all
instruction leaflets.
The customer must be made aware of the need for regular servicing of the appliance, this will
normally be once a year.
The customer should also be made aware that no rubbish should be thrown into the firebed and
that purpose provided ventilation should be chec ed regularly.
17 Servicing Instructions
Before commencing any servicing, ensure that the gas is isolated and the appliance is cool.
Cleaning – 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‘.
The coals contain refractory fibre (RCF). Excessive exposure to these materials may cause
temporary irritation to the eyes, s in and respiratory tract; consequently, it ma es sense to ta e
care when handling these parts to ensure that the release of dust is ept to a minimum. We
recommend the use of a HEPA filtered vacuum to remove any dust and soot accumulated in the
heater before and after wor ing on it. When replacing these articles, they should not be bro en up,
but sealed in heavy duty polythene bags labelled RCF Waste’, which may be disposed of at a tipping
site licensed for industrial waste. Protective clothing is not required, but normal hygiene rules of no
smo ing, eating or drin ing in the wor area should be followed.
Controls – The system for monitoring the oxygen supply to the burner is not adjustable and must
not be put out of operation. Should the oxypilot system need to be replaced, the original
manufacturer’s parts must be used.
Injectors – Only original manufacturer’s injectors must be used.
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. A combustion analysis chec should
be carried out using an analyser to BS7967 and sampling 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, pea
reading.

9.
Light the fire using the method in the instructions and ensure that the pilot lights consistently and
the pilot flame envelopes the thermocouple evenly, it is located at the front on the right-hand side.
The pilot should hold in 6-10 seconds. Turn control to main burner, this should light smoothly
within 10 seconds. Ensure the valve gives adequate turn down and the thermostat bulb reduces
the burner rate to off when heated.
Locate thermostat bulb in a cool place off the appliance and preferably outside of any inglenoo s,
to ensure it is sensing room air temperature.
Run the appliance for 10 minutes, ensuring burner flames settle evenly.
The gas manifold pressures are factory pre-set using highly accurate equipment, and must not be
altered.
The catalyst is unli ely to need replacement during the life of the heater. The appliance should be
inspected before use and at least annually by an authorised service person. More frequent cleaning
may be required due to accumulation of lint and dust from carpeting etc.
It is imperative that the control compartments, burners and circulating air passageways of the
appliance be ept clean. Replacement parts are available from your local dealer.
18 Accessories
The range of accessories for this stove includes dummy flue its, which simulate a real stovepipe
and warming shelves. Consult your dealer or Burley for a full list of optional accessories and follow
the instructions for their use.
Using unapproved accessories could prove hazardous and will invalidate the warranty.
User Ins ruc ions
Read the instructions before using this appliance.
This appliance requires installation and annual servicing by a Gas Safe™ registered installer
(formerly CORGI).
Use only in a correctly sized and ventilated area.
Any purpose provided ventilation should be chec ed regularly to ensure it is free from obstruction.
Once the coals or logs have been positioned in accordance with the installation instructions, they
must not be moved except for servicing.
The surfaces of the appliance become very hot during use.
Before cleaning or maintenance switch fire OFF and allow to
cool.
Do not attempt to touch or wipe clean the fire whilst hot,
doing so could result in severe burns or damage to the
paintwor .
TO LIGHT THE HEATER
There are 2 control nobs on the appliance. The left hand one (coloured red) controls On / Off and
High / Low flame. The right hand one (coloured blac ) is the comfort level thermostat which turns
the fire to pilot position once the desired temperature is reached. Some people prefer to retain a
flame effect using the left hand nob to control its height whilst eeping the thermostat set on hot.
Others prefer to use the fire purely as a heater in which case they will select a flame height then set
the thermostat to a comfort level. In both cases if the room gets too hot, the thermostat will reduce
the fire to pilot setting.
If during use the pilot is alight but the main burner will not light, chec the thermostat position and
if necessary select a warmer setting.

To light the fire, ensure the left hand (Blac ) control nob is turned fully cloc wise to OFF. Press the
red nob and turn slowly anticloc wise to the ignition position. A clic will be heard and the pilot
(under right side of fuel bed) should light. If it does not repeat the operation a few times. Continue
to hold red nob for 15 – 20 seconds to establish the pilot and then release. If pilot fails to establish,
turn off, wait 1 minute then repeat lighting procedure. Rotate the control nob to high flame to
light then bac to the desired flame position. If no gas comes through rotate the blac nob
(thermostat) to a hotter room setting and the fire will light.
Control the fire by a combination of thermostat and / or flame setting to suit your mode of use
To turn the fire off, rotate the red nob fully cloc wise.
NOTES
The first time that the appliance is used, there will be some odour produced due to the newness of
the materials. It is recommended that the unit is fired at maximum setting for several hours and the
room is ept ventilated during this period. It is usual for Flueless appliances to produce an initial
odour after start up.
If the pilot flame should ever extinguish of its own accord, ventilate the room and allow a minimum
of 5 minutes before relighting.
Never attempt to relight the unit if there is a smell of gas.
If the unit continues to extinguish after a period of use, do not use it and see the advice of your
installer.
TURNING OFF PROCEDURE
To extinguish the pilot, turn the valve to the OFF position. Note that if the gas supply fails at any
time, the pilot will extinguish. Carry out the lighting procedure to re-ignite.
Cleaning he fuel effec
Switch the appliance OFF and allow to cool before commencing. The fuels can be accessed by
opening the hinged door on the appliance which is secured by a 10mm nut. On no account should
the appliance be operated whilst the door is open.
Do not lay the coals in any way other than that shown in the Installation and Servicing Instructions.
• Do not use the fire with bro en coals.
• Do not add any additional fuel elements to the fire.
• Do not use similar loo ing parts from other appliances, use only genuine spare parts.
• Do not use the appliance for burning waste.

Addi ional Servicing and Technical Informa ion
1. Flue Gas Analysers – Ins alla ion & Servicing Fac s
• 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 wor s 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
Tes ing – Poin s o no e…
• Before testing ensure that the room size is correct for the heat output of the fire. 30cu³ for
2.5 w output, 40cu³ for 3.5 w and 50cu³ for 4.5 w.
• 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 wor , 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 exhaust vent, do
not stic the probe of the analyser in through the grill but move the probe bac and forth 1
inch in front of the outlet grill. (We use a piece of perforated 8mm pipe attached to the
analyser with flexible rubber tube). 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 CO as this will improve the
test
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 pea . 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)

12.
2. Poin s o No e Regarding he Ca aly ic Conver or!
• If the customer smo es tobacco products, lives on a busy road or is coo ing with a gas
oven/hob at the time of testing you must ensure that an ambient CO reading is ta en 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 bro en 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 wee , for up to
seven years. Periodically we send catalytic converters bac 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
ma es 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 vapors 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.

3. Gas ra ing 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.
Manufac urers 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 ta en 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 nown as
Burn Down.
Manufacturers carrying out their technical tests allow appliances to be fully warm and burn down
before ta ing 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.
Ins aller Tolerances
It is important to ta e 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 ma e 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.
