SAFETY WARNINGS FOR YOUR GUIDANCE
THIS STOVE WILL BE HOT when in operation and due care should
be taken. Thick gloves should be used to operate the primary/
secondary controls or reaching inside the stove to position fuel or
remove ash.
FIRES CAN BE DANGEROUS - Always use a fireguard in the presence of children, the elderly or the infirm. The fireguard should be
manufactured in accordance with B.S. 6539 - Fireguards for use
with solid fuel appliances.
DO NOT OVERFIRE - it is possible to fire the stove beyond its design
capacity. This could damage the stove, so watch for signs of
overfiring - if any part of the stove starts to glow red, the stove is
in an overfire situation and the controls should be adjusted
accordingly. Never leave the stove unattended for long periods
without first adjusting the controls to a safe setting. Careful air
supply control should be exercised at all times.
3

POSITIONING AND INSTALLATION
In England and Wales, there are only two routes to legally install a domestic
solid fuel or wood burning appliance. In other parts of the UK there are
variations in legislation and processes.
You can either:
• Use a registered installer who can self certify that the work he does
complies with the relevant Building Regulations; or
• The consumer applies to their local authority building control
department for a building notice, and pays the appropriate fee.
It is generally worthwhile to use a HETAS registered installer who will supply a
Certificate of Compliance as a record of the job and that it complies with
Building Regulations. A copy of the certificate is forwarded to HETAS who
notify the local authority on your behalf.
Failure to notify the work through the registration scheme (in this case HETAS)
or directly to the local authority can lead to enforcement. It can also cause
problems for future house sales if there is no official record of a compliant
installation. All local regulations, including those referring to National and
European Standards need to be complied with when installing this appliance.

For specific guidance when cast iron stoves are being installed in boats or
homes with thatched roofs, please refer tothe SOLIFTEC website at;
www.soliftec.com/installation.htm
SUPPORTING FLOORS
The stove must only be installed on floors with an adequate load bearing
capacity and if the existing construction is not suitable, additional measures
such as a load distributing plate must be provided.
The hearth should be able to accommodate the weight of the stove and its
chimney if the chimney is not independantly supported. Stoves should stand
wholly above hearths made of non-combustible board/sheet material or tiles
at least 12mm thick, if the stove is not to stand in a recess and has been
tested to an applicable standard to verify that it cannot cause the
temperature of the upper surface of the hearth to exceed 100 degrees C.
Constructional hearths should be made of solid, non-combustable material
such as concrete or masonry, at least 125mm thick, including the thickness of
any non-combustible floor and/or decorative surface.
Specific guidance for surfaces on which the stove may be allowed to stand is
given in Approved Document J and must be followed.
When the stove is positioned near a wall constructed of flammable material,
the distances shown on Fig 4 must be adhered to. Alternatively, a heat shield
may be used, mounted according to the position of the fireplace. A firewall
must be at least 100 mm thick and typically made of brick, or concrete/
stone.
MATERIAL CLEARANCES
The stove must have a minimum clearance of 1200 mm to a combustible
ceiling above.
Fig 4
It is recommended that the stove be installed at least 650 mm from
combustible materials. However, any household furnishings should be at least
1000 mm away as they could be adversely affected by heat.
7
The stove can be recessed in a suitable sized fireplace but a permanent free
air gap of at least 200mm must be left around the sides and top and at least
50mm at the back of the stove to obtain maximum heat output and for
access to the rear of the stove.
MINIMUM DISTANCE TO COMBUSTIBLE MATERIALS
Note: combustible material refers to any material that will degrade when
subjected to heat e.g. plaster.
Due to the heat of a hot stove, a suitable fire guard should always be used to
provide additional protection. Never allow young children to be left
unsupervised in a room containing a hot stove.
Note; If in doubt, refer to the Building Regulations 2000 Approved Document
“J”.
THE CHIMNEY
The stove is supplied with a flue pipe connector for top or rear mounting with
the fixing screws supplied. The stove should never be connected to a shared
chimney/flue system.
Flue pipes with a smaller cross-sectional area than that of the stove outlet
should never be used. Flue pipes must not project into the chimney
connector, such as to cause a restriction to the gas flow.
Sizes of flues in chimneys are stipulated in Table 2 of the Building Regulations
2000 Approved Document “J” as follows:
1. Stoves under 20kW rated output which burn smokeless or low volatile fuel
require a minimum flue size of 125mm diameter (or rectangular flues
having the same cross-sectional area and a minimum dimension not less
than 100mm for straight flues or 125mm for flues with bends or offsets.
2. Stoves of up to 30kW rated output burning any fuel require 150mm diameter (or rectangular flues having the same cross-sectional area and a
minimum dimension not less than 125mm.
Liners should be installed in accordance with their manufacturers instructions.
Appropriate components should be selected to form the flue without cutting
and to keep joints to a minimum. Bends and offsets should be formed only
with the matching factory-made components. Liners need to be placed with
the sockets or rebate ends uppermost to contain moisture and other
condensates in the flue. Joints should be sealed with fire cement, refractory
mortar or installed in accordance with their manufacturers instructions. Ensure
the joints are completely sealed as air leakage will lead to poor
performance. Avoid having more than two bends in the flue system. Any
offset between bends should be minimised and the flue should be equipped
with suitable access doors for inspection & cleaning. For further detail refer to
Building Regulations document “J”
8
THIS STOVE MUST NOT BE INSTALLED INTO A CHIMNEY THAT SERVES ANY
OTHER HEATING APPLIANCE. THERE MUST NOT BE AN EXTRACTOR FAN
FITTED IN THE SAME ROOM AS THE STOVE, AS THIS CAN CAUSE THE
STOVE TO EMIT FUMES INTO THE ROOM.
FLUE HEIGHT
The chimney height and the position of the chimney should conform to the
Building Regulations document “J”. Flues should be high enough to clear the
products of combustion. The height necessary for this will depend on the type
of the appliance, the height of the building, the type of flue and the number
of bends in it, and an assessment of local wind patterns. However, a minimum
flue height of 4.5m could be satisfactory if the guidance in paragraphs 2.10
to 2.12 of the Approved Document “J” is adopted.
External flue pipes should be Twin Wall. These retain the heat, enabling it to
rise and disperse from the chimney.
Fig 5
As an alternative approach, the calculation procedure within BS EN 133841:2005 can be used as the basis for deciding whether a chimney design will
provide sufficient draught. If in doubt, consult the Building Regulations.
The outlet from a flue should be above the roof of the building in a position
where the products of combustion can discharge freely and will not present
a fire hazard, whatever the wind conditions.
9
BENDS IN FLUES
Openings for inspection & cleaning should be formed using purpose factorymade components compatible with the flue system, having an access cover
that has the same level of gas-tightness as the flue system and an equal level
of thermal insulation.
Offsets in flues are only acceptable if the following rules are respected:
a) The chimney system shall have no more than 4 bends in total; - 2 bends in
the chimney and 2 bends in the flue pipe connection.
b) The offset shall provide a change of direction no more than 45 degrees
from the vertical.
c) The run of the chimney between bends shall not exceed 20% of the total
chimney length.
d) the maximum length of the horizontal flue must not exceed 150mm (6”).
INSPECTION & CLEANING
Check that the chimney is in good condition, dry and free from cracks and
obstructions. The diameter of the chimney should not be less than 150mm
and not more than 230mm. If any of these requirements are not met, the
chimney should be lined by a suitable method.
The chimney must be swept before connection to the stove. Where the
chimney is believed to have previously served an open fire installation, it is
possible that the higher flue gas temperature from the stove may loosen
deposits that were previously firmly adhered, with the consequent risk of flue
blockage. It is therefore recommended that the chimney be swept a second
time within a month of regular use after installation.
Assuming that when the stove is first installed, the chimney is clean, and
sound, then the chimney flue should be inspected part way through the
burning season to establish the regularity of sweeping required. If you have
any doubts about the suitability of your chimney, consult your local dealer/
stockist.
If there is no existing chimney, then a prefabricated block chimney in
accordance with Building Regulations Approved Document J, or a twinwalled insulated stainless steel flue to B.S.4543 can be used. These chimneys
must be fitted in accordance with the manufacturer’s instructions and
Building Regulations.
FLUE DRAUGHT
A flue draught of minimum 1.2mm to a maximum 2.5mm water gauge is
required for satisfactory stove performance. The flue draught should be
checked under fire at high output. If it exceeds the recommended
maximum, a draught stabiliser must be fitted so that the rate of burning can
be controlled to prevent over-firing. If the reading is less than the
recommended minimum, then the performance of the stove will be
compromised.
10
AIR FOR COMBUSTION
Any room or space containing a stove should have a permanent air vent
opening of at least the sizes shown in the table below. For stoves designed to
burn a range of different solid fuels, the air supply should be designed to
accommodate burning the fuel that produces the highest heating output.
There must always be a permanent means of providing air for combustion
into the room in which the fire is installed. A permanent vent with a total free
area of at least 550mm2 for every kW rated above 5kW should be connected
directly to the outside air or an adjacent room which itself has a permanent
vent of the same size direct to the outside air. The fitting of an extractor fan to
either of these rooms is not permitted.
Stove Air Supplies
Permanently open vents as below:
Stove with flue draught
stabiliser
If design air permeability>5.0m3/(h.m2) then
300mm2/kW for first 5kW of appliance rated output
850mm2/kW for balance of appliance rated output
If design air permeability<5.0m3/(h.m2) then
850mm2/kW for balance of appliance rated output
Permanently open vents as below:
Stove with no flue draught
stabiliser
If design air permeability>5.0m3/(h.m2) then
550mm2/kW of appliance rated output above 5kW
If design air permeability<5.0m3/(h.m2) then
550mm2/kW for balance of appliance rated output
CONNECTION TO THE CHIMNEY
This MUST be carried out by an accredited/competent person and/or
approved by your local Building Control Officer before using the stove.
Any existing flue must be in good condition with suitable access for collection
and removal of debris. Details of suitable linings for use with solid fuel are
given in the Official HETAS guide that can be viewed on their website at
www.hetas.co.uk
It is also important that suitable flue pipe complying with Building Regulations
is used to connect the stove to the chimney flue and that suitable access is
provided into the flue for regular inspection and sweeping of the flueways.
Chimneys should be as straight as possible. Horizontal runs should be
avoided except where the rear outlet of the appliance is used, in which case,
the horizontal section should not exceed 150mm (6 inches) in length. Refer to
the typical installation diagrams, Fig 6-7. Flue connections must be well
sealed.
11
Fig 6: Horizontal register plate
with top flue connection
Fig 7: Horizontal register plate
with optional vertical rear flue
connection
There are different ways of connecting the stove to the flue as shown in
Figures 6-7. If a vertical rear flue is used, the chimney may be swept through
the appliance. If it is not possible to pass the sweeps brush through the stove,
a soot door will be necessary. This may be either in the actual brickwork of
the chimney or fitted in the register plate. Different suitable positions of soot
doors are shown in Figures 6-7.
12
A non-combustible register plate
minimum 1.5 mm thick should be fitted
to all installations between the flue and
the building structure. It’s suitability and
fit should be checked by a qualified
stove installation engineer against the
current Building Regulations.
Fig 8
CLEANING THE FLUE
Access for cleaning the flue should be incorporated in the system other than
through the appliance (e.g. a soot door or access through a register plate).
Purpose-made soot doors and inspection lengths are available from the
Clarke range.
Ensure that the whole length of the flue can be reached from the soot door.
FUME EMISSIONS
To avoid chimney problems, your fire should not be burnt slowly for longer
than 12 hours without a period of fast burning.
Properly installed and operated, this stove will not emit fumes. Occasional
fumes from de-ashing and refuelling may occur. Persistent fume emission must
not be tolerated. If fume emission persists, the following immediate action
should be taken:1. Open doors and windows to ventilate room.
2. Let the fire out, or eject and safely dispose of fuel from the stove.
3. Check for flue chimney blockage and clean if required.
4. Do not attempt to re-light the fire until the cause has been identified and
corrected.
If necessary, seek professional advice.
Important! Never fit an extractor fan in the same room as this stove.
13
CARBON MONOXIDE ALARMS
Due consideration should be given to the dangers of carbon monoxide
poisoning following incomplete combustion of solid fuels in an enclosed
space. Carbon monoxide detectors to BS EN 50291 are available for use in
domestic premises and details are available in the official HETAS guide that
can be viewed on their website at www.hetas.co.uk.
Where a new or replacement fixed solid fuel appliance is installed in a
dwelling, a carbon monoxide alarm should be provided in the room where
the appliance is located.
Carbon monoxide alarms should comply with BS EN 50291:2001 and be
powered by a battery, designed to operate for the working life of the alarm.
The alarm should incorporate a warning device to alert users when the
working life of the alarm is due to pass. Mains-powered BS EN 50291 Type A
carbon monoxide alarms with fixed wiring (not plug-in types) may be used as
alternative applications, provided they are fitted with a sensor failure warning
device.
The carbon monoxide alarm should be located in the same room as the
appliance:
a. On the ceiling at least 300mm from any wall or, if it is located on a wall, as
high up as possible (above any doors and windows) but not within 150mm
of the ceiling; and
b. between 1m and 3m horizontally from the appliance.
Note: Further guidance on the installation of carbon monoxide alarms is
available in BS EN 50292:2002 and from manufacturers instructions. Provision
of an alarm should not be regarded as a substitute for correct installation and
regular servicing.
14
USING YOUR STOVE
THE CONTROLS
The amount of heat emitted by
the stove is regulated using the
following air controls:
A) The primary air supply is controlled using the air regulator
built into the front door. This
controls the burn rate and is
opened to enable the stove to
create more heat.
B) The cooking lid rests on top of
the stove and will affect the
airflow drawn across the top of
the fire if removed for cooking.
C) A third air supply is controlled
by turning the butterfly damper
mounted in the flue to provide
an updraught to the chimney.
It can be opened to reduce
any smoking from the fire but should be
closed off at night or when the stove is unattended.
Fig 9
WARNING: THE TEMPERATURE REACHED BY THESE ITEMS DURING
OPERATION MAY CAUSE AN INJURY TO AN END-USER. AS THESE ARE
INTENDED TO BE ADJUSTED DURING OPERATION, IT IS RECOMMENDED
THAT PROTECTIVE GLOVES ARE WORN WHEN HANDLING THESE PARTS.
TYPES OF FUEL
The Boxwood and Boxwood Deluxe are designed primarily for use with wood
unless the optional Coal Grates are obtained. These removable grates allow
coal or coke burning as follows:.
Boxwood Grate:-
Part No 6910066
Boxwood Deluxe Grate:- Part No 6910071
A mixture of fuels can be used in conjunction with wood, provided the base
of the fire remains as wood or compressed block fuels. Coal products can be
added to this, provided the volume of coal products is less than that of other
fuels.
With solid fuels, there is less need to burn the stove hard after refuelling. The
rate of refuelling will also be less often than with wood.
15
This stove will function with wood or coal, but in general all fuel should be dry
and timber should be well seasoned so as to have a moisture content below
20%. The use of damp wood will result in more soot and tar deposits being left
in the chimney, flu and stove, and will not release heat if thermal energy is
being used to drive out moisture from the fuel.
Other fuels can be used in conjunction with wood, provided the base of the
fire remains as wood or compressed block fuels. Coal products can be
added to this provided the volume of coal products is less than that of other
fuels.
With solid fuels, there is less need to burn the stove hard after refuelling. The
rate of refuelling will also be less often than with wood.
Avoid using the stove to incinerate other materials including household
waste.
Avoid using ‘green’ unseasoned wood, treated wood such as telegraph
poles, or plywood / chipboard containing glues and resins which pollute the
environment and cause the fire to burn too quickly. Such materials can
produce excessive tar or creosote which can be damaging and in extreme
cases cause a fire inside the chimney.
The dryness of wood can be assessed by looking at the end of the log. Radial
cracks, deep enough to be considered as splits should be present in dry,
seasoned logs. This level of dryness may take up to two years to achieve.
The maximum length of fuel suitable for this stove is approx 50 cm so as to lay
flat over the embers, and logs of greater than 10 cm diameter should be split.
Confirm with your fuel provider as to which type will suit best. Larger fuels will
allow a greater draught in the firebox which will speed up combustion.
Household coal produces more ash & chimney deposits than smokeless fuels.
For further information on type and availability of fuel, the Solid Fuel Association (http:/www.solidfuel.co.uk) serves as an advice centre to domestic
consumers including all aspects of fuel types.
The UK Smoke Control Areas website (http:/www.uksmokecontrolareas.co.uk)
defines the location of smoke controlled areas throughout England, Scotland,
Wales and Northern Ireland and lists all fuels which are authorised for use in
Smoke Control Areas.
INITIAL SEASONING
Following installation, and before regular use, the stove must be seasoned to
prevent cracking of the metal casting. This procedure should also be
followed if the stove has not been used for prolonged periods (during the
summer months for example), and is carried out as follows:
1. Light a small fire in the middle of the stove, well away from the sides.
2. Allow the stove to warm up slowly and evenly with the air controls almost
closed, avoiding intense flames.
16
3. Keep the fire burning for three hours or so, gradually increasing the size of
the fire using larger logs which will burn naturally but slowly, keeping the
stove on a low setting.
4. After a couple of days burning at this level, increase the brightness &
intensity of the fire gradually over the next 10 days. Full strength fires should
not be used until completion of approx 20 days of mild use. Only from this
time will the stove have been properly seasoned.
It should be remembered that this procedure should be carried out at the
beginning of each season of use in order to remove the moisture retained by
the metal during the period of non-use.
When used for the first time the fireplace may smell a little, due to gas being
given off. The gas is not toxic but the room should be thoroughly ventilated.
Let the fire burn with a high draught until no smells can be detected.
Take care not to open the stove doors too vigorously in case of causing
smoke spillage. If smoke spillage occurs after the fire door has been opened
this could be due to poor chimney draft. SEE TROUBLESHOOTING.
FIRE-LIGHTING WITH WOOD
1. Open the air controls.
2. Lay firelighters or rolled up newspapers on the grate with a reasonable
quantity of dry kindling wood. Place 2 or 3 small logs on top.
3. Light the newspaper or firelighters using a long taper and close the door.
4. When the fire is burning strongly, add further logs up to 10mm diameter.
5. When the stove is really hot, close the front air control as required. Ensure
there are lasting flames until the wood becomes charcoal.
FIRE-LIGHTING WITH SOLID FUEL
1. Open the air controls.
2. Lay firelighters or rolled up newspapers in the stove with a reasonable
quantity of dry kindling wood. Place a small quantity of solid fuel on top.
3. Light the newspaper or firelighters using a long taper and close the door.
4. When the fire is burning strongly, add further fuel.
5. When the stove is hot, reduce the opening of the air controls.
6. The burn rate can be reduced by partially closing the air controls or
damper.
REFUELLING
1. Always open the doors slowly to avoid a sudden rush of intake air and
smoke escaping into the room and add fuel.
2. Open the air controls and leave open for a few minutes to allow the
gasses in the wood to burn before closing the air controls.
17
• The rate of refuelling and heat available are dependant upon individual
requirements based upon the user’s experience. When re-loading, it is
normally necessary to burn the stove fast initially, to drive off any gasses
and moisture, before closing the air vents to control the burn rate.
• Ensure the doors are kept closed to contain fumes except when lighting
up, re-fuelling or removing ash.
• It is not recommended to leave the stove alight at night or to continue
using the stove in mild weather which gives poor combustion leading to a
greater buildup of soot.
• If overnight burning is required, can best be achieved by first driving off
any gasses or moisture as usual, following a full charge of fuel and then
closing the air vents fully. Experience will indicate the optimum setting.
However, by reducing the burn rate to such a level that the fire is still
burning the following day, the burning process creates heavy, tarry
chemicals which will become deposited on the inside of the flue or
chimney. This is an inefficient process which greatly increases the risk of a
chimney fire and makes it necessary to sweep the chimney more often.
ASH REMOVAL
Keep the stove free from a heavy buildup of ash. The frequency of this is
dependant upon the type and quality of fuel being used. Ash should be
removed before it builds up to the underside of the grate, at which point, the
grate would be burning hot on both sides, shortening its life expectancy.
When disposing of ashes, ensure they have cooled and always place in a
metal container. Be sure to remove the ash when the fire is at its lowest point,
such as first thing in the morning.
An Ash Can Filter is ideal for use in conjunction with the Vac King range of
vacuum cleaners, for collecting hot ash and debris from stoves.

MAINTENANCE
CLEANING
The inside of the stove may require regular cleaning, especially during periods
of peak use, the frequency of this being indicated by experience. It is
advisable to wear a dust mask, protective gloves and safety glasses when
cleaning.
Use a stiff brush and industrial type vacuum cleaner to dislodge and remove
as much material as possible, starting at the top of the stove and working
down to the bottom. Particular attention should be given to the air inlet
controls which can become obstructed. A CVAC Ash Can Filter and Vac King
vacuum cleaner is ideal for this process.
GENERAL MAINTENANCE
Take this opportunity to check for any damaged parts inside the stove. In the
event of damage or broken components, replacements can be obtained
from Clarke Parts & Service. On no account should unauthorised spare parts
be used.
The stove and flueway should be inspected and maintained when in a cold
condition. No unauthorised modification of this product should be carried
out. This stove requires regular maintenance by a competent engineer.
STOVE BODY
The stove is finished with a heat-resistant paint which can be cleaned with a
soft brush. Wait until the stove has cooled down before doing this. This finish
can be renovated with Clarke stove paint,although the paint may not be an
exact match and it may be necessary to repaint the complete stove.
If the stove is purely ornamental, painting will provide a durable, attractive
finish. If the stove is used for heating, a high temperature heat resistant paint
(available from your Clarke dealer) must be used, in either aerosol or brush
applied form. Should rust become apparent, clean thoroughly with a wire
brush and apply a suitable anti-rust treatment.
During prolonged periods out of use, the air inlets should be left open and the
door left slightly ajar in order to circulate fresh air and discourage
condensation from forming which could encourage corrosion.
FIRE ROPE
Check the rope around the door, top panel and lids. If rope is becoming
detached, replace with rope approved for this purpose.
Inspect the fireproof door seals where fitted, to ensure there is an effective
seal around the door and re-fix it if loose using stove rope adhesive. If in poor
condition it should be replaced.
20
BAFFLE (DE-LUX ONLY)
This should be removed & cleaned at least once a month to prevent any
buildup of soot or fly ash that could lead to blocked flu-ways and dangerous
fume emission. If the baffles are removed, the chimney/flue way can be
swept through the appliance.
CHIMNEYS AND FLU-WAYS
It is important that the chimney, flu-ways and any connecting flue pipe are
swept regularly. This means at least once a year for smokeless fuels and at
least twice a year for wood and other fuels.
Only wire-centred sweep’s brushes fitted with a guide wheel should be used.
If it is not possible to sweep all parts of the chimney through the stove, ensure
there is adequate access to cleaning doors.
If the stove is fitted in place of an open fire, then the chimney should be
swept one month after installation to clear any soot falls which may have
occurred, due to the difference in combustion performance between the
stove and the open fire.
The flue and chimney should be inspected for a buildup of deposits
especially following prolonged periods without use. The entire chimney/flue
should be swept frequently from top to bottom by a registered chimney
sweep to remove any buildup of soot etc, the frequency being dependant
upon the usage and the fuels being burnt. If the chimney is swept after a few
weeks of regular use, the condition found will give an indication of the
frequency of sweeping required. On an annual basis, the chimney is best
swept just before the main winter burning season.
HETAS recommends that chimney sweeping is best carried out by an
approved chimney sweep who will normally be a member of the National
Association of Chimney Sweeps or the Guild of Master Sweeps, details of
which can be found on the HETAS website, www.hetas.co.uk.
