These instructi ns c ver the basic principles t ensure satisfact ry installati n f the st ve, alth ugh detail may need slight
m dificati n t suit particular l cal site c nditi ns. In all cases the installati n must c mply with Nati nal and Eur pean
Building Regulati ns, L cal Auth rity Byelaws and ther specificati ns r regulati ns as they affect the installati n f the
st ve.
It sh uld be n ted that the Building Regulati ns requirements may be met by ad pting the relevant rec mmendati ns given in
British Standards BS 8303, BS EN 15287-1:2007 as an alternative means t achieve an equivalent level f perf rmance t that

Health and Safety Precauti ns
Handling
Adequate fa ilities must be available for unloading and site handling.
Fire Cement
Some types of fire ement are austi and should not be allowed to ome into onta t with the skin. In ase of
onta t, wash immediately with plenty of water.
Asbest s
This stove ontains no asbestos. If there is a possibility of disturbing any asbestos in the ourse of installation
then please seek spe ialist guidan e and use appropriate prote tive equipment.
Metal Parts
When installing or servi ing this stove, are should be taken to avoid the possibility of personal injury.
Please n te:
Any white deposits on the stove joints are aused by humidity rea ting with the joint sealant. These deposits
may be brushed off and, if ne essary, bla kened with a proprietary stove polish.
Imp rtant Warning
This stove must n t be installed into a himney that serves any other heating applian e.
Chimney
In order for the stove to perform satisfa torily the himney height must be suffi ient to ensure an adequate
draught of between 12 Pa and 25 Pa so as to lear the produ ts of ombustion and prevent smoke problems into
the room.
NOTE: A himney height of not less than 4.5 metres measured verti ally from the outlet of the stove to the top
of the himney should be satisfa tory. Alternatively the al ulation pro edure given in EN 13384-1 may be
used as the basis for de iding whether a parti ular himney design will provide suffi ient draught.

The outlet from the himney should be above the roof of the building in a ordan e with the provisions of
Building Regulations Approved Do ument J.
If installation is into an existing himney then it must be sound and have no ra ks or other faults whi h might
allow fumes into the house. Older properties, espe ially, may have himney faults or the ross se tion may be
too large i.e. more than 230 mm x 230 mm. Remedial a tion should be taken, if required, seeking expert advi e,
if ne essary. If it is found ne essary to line the himney then a flue liner suitable for solid fuel must be used in
a ordan e with Building Regulations Approved Do ument J.
Any existing himney must be lear of obstru tion and have been swept lean immediately before installation of
the stove. If the stove is fitted in pla e of an open fire then the himney should be swept one month after
installation to lear any soot falls whi h may have o urred due to the differen e in ombustion between the
stove and the open fire.
If there is no existing himney then any new system must be to the designation des ribed above and in
a ordan e with Building Regulations Approved Do ument J.
A single wall metal fluepipe is suitable for onne ting the stove to the himney but is not suitable for use as the
omplete himney. The himney and onne ting fluepipe must have a minimum diameter of 150 mm and its
dimension should at no point be less than the size of the outlet so ket of the stove.
Any bend in the himney or onne ting fluepipe should not ex eed 45°. 90° bends should not be used.
Combustible material should not be lo ated where the heat dissipating through the walls of firepla es or flues
ould ignite it. Therefore when installing the stove in the presen e of ombustible materials due a ount must
be taken of the guidan e on the separation of ombustible material given in Building Regulations Approved
Do ument J and also in these stove instru tions.
If it is found that there is ex essive draught in the himney then a draught stabiliser should be fitted.
Adequate provision e.g. easily a essible soot door or doors must be provided for sweeping the himney and
onne ting fluepipe.
Hearth
The hearth should be able to a ommodate the weight of the stove and its himney if the himney is not
independently supported. The weight of the stove is indi ated in the bro hure.
The stove should preferably be installed on a non- ombustible hearth of a size and onstru tion that is in
a ordan e with the provisions of the urrent Building Regulations Approved Do ument J.
The learan e distan es to ombustible material beneath, surrounding or upon the hearth and walls adja ent to
the hearth should omply with the guidan e on the separation of ombustible material given in Building
Regulations Approved Do ument J and also in these stove instru tions.
If the stove is to be installed on a ombustible floor surfa e, it must be overed with a non- ombustible material
at least 12mm thi k, in a ordan e with Building Regulations Approved Do ument J, to a distan e of 30 m in
front of the stove and 15 m to ea h side measuring from the door of the ombustion hamber.

C mbusti n air supply
In order for the stove to perform effi iently and safely there must be an adequate air supply into the room in
whi h the stove is installed to provide ombustion air. The provision of air supply to the stove must be in
a ordan e with urrent Building Regulations Approved Do ument J. An opening window is not appropriate
for this purpose. If it was ne essary to fit a draught stabilizer due to ex essive himney draught then attention
must be paid to the permanent ombustion air requirements as this will be different as detailed in Approved
Do ument J.
C nnecti n t chimney
All the stoves have a hoi e of either rear or top flue gas onne tor that allows onne tion to either a masonry
himney or a prefabri ated fa tory made insulated metal himney in a ordan e with the instru tions. It may be
ne essary to fit an adaptor to in rease the diameter of the flue to the required 150 mm se tion of the himney or
liner.
Material Clearances
The stove an be re essed in a suitable sized firepla e but a permanent free air gap of at least 150mm must be
left around the sides and top and at least 50mm at the ba k of the stove to obtain maximum heat output and for
a ess to the rear of the stove.
All non- ombustible walls loser than 400mm to the stove should be at least 75mm thi k. In all instan es the
ba k wall of the firepla e re ess and the hearth should be made of non- ombustible material. Allow an apron of
at least 300mm at the front of the stove and 150mm on either side. The hearth on whi h the stove is to be pla ed
should not be less than 125mm thi k and should be in a ordan e with the urrent building regulations.
Care should be taken to level the stove using the adjusting s rews in the feet.
The applian e shall be installed on a floor with adequate load-bearing apa ity. If the existing onstru tion does
not meet this prerequisite, suitable measures (e.g. load disturbing plate) should be taken to a hieve it.

B iler C nnecti n

It is str ngly rec mmended that this st ve is fitted t y ur heating system by a kn wledgeable,
experienced and suitably qualified (Hetas r equivalent) plumber r Heating Engineer with experience in
fitting b iler st ves. If fitted inc rrectly it c uld result in seri us damage t y ur h me heating system.
Plumbing sh uld be carried ut in acc rdance with Relevant Building Regulati ns and safe practices.
The manufacturers cann t be held resp nsible f r any l sses due t inc rrect specificati n r c nnecti n
f the heating system.
Gravity Circuit
D N t – Under any ir umstan es onne t the stove to a sealed (pressurised) heating system or an unvented
HW ylinder
D N t – Link the stove into a heating or hot water system with an existing boiler without the use of suitable
equipment su h as a neutralizer. When fitting this type of system the neutralizer manufa turer’s instru tions
must be followed.
D – Fit an open old feed and header expansion tank with separate old feed and vent pipes. The old feed
and vent pipes must be unvalved. The open vent pipe should have a diameter of 22mm and rise ontinuously
from the boiler.
The gravity ir uit should onne t to a domesti indire t hot water ylinder of minimum 135lt apa ity, using
28mm flow and return pipes, rising ontinuously from the boiler to the ylinder. Any nominally horizontal runs
of gravity pipework should slope upwards at not less than 1:30. The base of the hot water ylinder should be
lo ated at least 150mm above the top of the stove. The gravity ir uit must not ontain any shut off valves and
should be fully lagged to minimise heat loss. The pipes should not ex eed 7.8 meters (25ft) in length to/from the
ylinder. In general, the shorter the run of pipework the less heat loss and the more effi ient the water heating.
A heat soak radiator of at least 2kW must be used on the same gravity ir uit, positioned above the stove. This
is used to dissipate heat when the entral heating is swit hed off or the HW ylinder is fully heated.

Link Up:
On heating and hot water installations, a semi-pumped system should be used to the entral heating system with
gravity ir ulation to the hot water ylinder. For optimum performan e of the boiler we re ommend that all 4
tappings are used when using separate gravity and pumped heating loops. The flow and return pipes should be
taken from diagonally opposite sides of boiler.
Inject r Tee:
If only two tappings are used on a ommon flow system, they should be taken diagonally opposite and the
remaining tappings should be plugged. An inje tor Tee should be fitted to join the gravity feed and entral
heating ir uits ba k to the stove, whi h should be situated as lose to the stove as possible. The tee onne tion
en ourages the stable flow of water through both ir uits and prevents priority being given to the stronger flow,
typi ally the pumped ir uit.
Pipe Therm stats
A HIGH LIMIT thermostat should be fitted to the gravity flow pipe lose to the boiler and set at 90°C.This
should override any pump ontrol, swit hing the pump on and dissipating any ex ess heat around the radiator
ir uit. To prevent boiler orrosion due to ondensation it is ne essary to maintain the return water temperature
above 45°C. This an be a hieved by the use of a LOWLIMIT thermostat on the return pipe from the hot water
ylinder, lose to the boiler. The thermostat should make on temperature rise, preventing the ir ulating pump
from operating until the gravity ir uit is up to temperature
C mmissi ning and Hand ver
Upon ompletion of the installation, allow a suitable period of time for any fire ement and mortar to dry out. A
small fire may then be lit and he ked to ensure the smoke and fumes are taken from the stove up the himney
and emitted safely to atmosphere. Do not run the stove at full output for at least 3 – 4 days.
On ompletion of the installation and ommissioning, ensure that the operating instru tions and operating tools
for the stove are left with the ustomer. Ensure to advise the ustomer on the orre t use of the applian e with
the fuels likely to be used on the stove and warn them to use only the re ommended fuels for the stove.
Advise the user on what to do should smoke or fumes be emitted from the stove. The user should use a suitable
fireguard in the presen e of hildren, aged and/or infirm persons.
All onne tions to the boiler should be he ked to ensure there are no leaks during operation and that the flow
and return water onne tions are working properly. The stove should be fired up initially by the Plumber /
Heating Engineer to ensure that it is operating safely with the rest of the heating system.
.

Operating Instructi ns
This applian e is n t suitable for use in a shared flue.
This applian e should n t be operated with the doors open.
This applian e is apable of intermittent operation.
Aer s l Sprays
Do not use an aerosol spray on or near the stove when it is alight.
Air C ntr ls
This stove has been designed to burn lean and effi ient. If used orre tly this stove will burn far more
effi iently than normal with the obvious notable features of CLEAN GLASS. Never lean glass when stove is
hot. Always use stove glass leaner whi h is available from your stove retailer.
However, for this produ t to work properly it must be used orre tly.
It is essential that the stove has an adequate air supply for ombustion and ventilation.
The primary and se ondary air inlets must be kept lear from obstru tion.
Warning! This applian e will be h t when
In operation and due are should be taken
When operating the ontrols.
Air C ntr ls
Primary Air
Primary air is ontrolled via the two rotary air ontrols on the bottom of the door.
This provides a onventional air draught to the bed of the fire. The primary air intakes an be adjusted to give
the best possible results when burning different fuels.
Sec ndary Air
The ast iron stove is fitted with an “air wash” system. This se ondary air supply to the stove is ontrolled
through a rotary ontrol assembly lo ated at the top of the stove, above the door.
Grate
Your Green Stove is fitted with a rotary style grate, whi h is operated from the front of the stove via a riddle
rod. Use the “Hook” end of tool to operate the riddling system. This rotary grate is lo ated in the entre of a ast
iron flat bed with suitable air slots that assist the burning of most fuels. It is important to use the rotary grate to
de-ash regularly, to ensure that the primary airflow is not impeded, as a build-up of ash an damage the ast iron
bed.
Ashpan
It is essential that you empty the ashpan regularly. Use the “T” end of tool to lift the ashpan out of the stove.

N tes n W d burning
With a full load of wood, the stove will need to be refuelled approximately every 1.5 hours. Wood an be
sta ked higher in the stove than solid mineral fuel but are must be taken that logs do not tou h the baffle.
Wood burns most effi iently with the primary air ontrols losed and the se ondary ontrol partially open.
Moving the se ondary ontrol will ontrol the burn rate of the stove.
Note – primary and se ondary air is needed to light the stove, see se tion entitled
‘Lighting the Stove’.
Wood burns best on a bed of ash and it is therefore only ne essary to remove surplus ash from the stove
o asionally.
Burn only dry, well-seasoned wood, whi h should have been ut, split and sta ked for at least 12 months, with
free air movement around the sides of the sta k to enable it to dry out. Burning wet or unseasoned wood will
reate tar deposits in the stove and himney and will not produ e a satisfa tory heat output. Do not use liquid
fuels in this applian e.
Lighting the St ve
We re ommend that you have two or three small fires before you operate your stove to its maximum heat
output. This is to allow the paint to ure in steadily and to give a long servi e life of the paint finish. During this
uring in pro ess you may noti e an unpleasant smell. It is non-toxi , but for your omfort we would suggest
that during this period you leave all doors and windows open.
First, load the fire with starting fuel, i.e. paper, dry sti ks and/or firelighters in the mode hosen, either wood or
solid mineral fuel.
Light the fire at the base leaving all air ontrols open. Allow the fuel to rea h a steady glow and build the fire up
gradually. On e you have a good fire established a ross the grate bed, further fuel an be added as required.
Shutting D wn
In order to shut down the stove, lose the primary air ontrols, then lose the se ondary air rotary ontrol by
moving the handle all the way to the left. If the ontrols are left in this position, the fire will be starved of air
and will go out. If you want to revive the fire it is re ommended that the primary air ontrols are open first, and
then open the se ondary air rotary ontrol.
Warning! - The stove will remain h t for a onsiderable time after the fire has been extinguished.
N tes:
Warning! - Petroleum oke fuels, household waste or liquid fuels must not be burnt on this applian e.
Should any diffi ulties arise over fuel quality or suitability, onsult your lo al approved oal mer hant.
Chimney cleaning
The himney should be swept at least twi e a year. It is important that the flue onne tion and himney are swept
prior to lighting up after a prolonged shutdown period.
If the stove is fitted in pla e of an open fire then the himney will require sweeping after a month of ontinuous
operation. This is a pre aution to ensure that any “softer” deposits left from the open fire usage have not been
loosened by the higher flue temperatures generated by the losed stove.

In situations where it is not possible to sweep through the stove the installer will have provided alternative
means, su h as a soot door. After sweeping the himney the stove flue outlet and the flue pipe onne ting the
stove to the himney must be leaned with a flue brush.
Peri ds f Pr l nged N n-Use
If the stove is to be left unused for a prolonged period of time then it should be given a thorough lean to
remove ash and unburned fuel residues. To enable a good flow of air through the applian e to redu e
ondensation and subsequent damage, leave the air ontrols fully open.
Safety N tes f r y ur guidance
FIRES CAN BE DANGEROUS – Always use a fireguard in the presen e of hildren, the elderly or the infirm.
DO NOT OVERFIRE – it is possible to fire the stove beyond its design apa ity, this ould damage the stove,
so wat h for signs of overfiring – if any part of the stove starts to glow red, the fire is in an overfire situation
and the ontrols should be adjusted a ordingly. Never leave the stove unattended for long periods without first
adjusting the ontrols to a safe setting – areful air supply ontrol should be exer ised at all times.
Any unauthorised modifi ations of this applian e will render the guarantee null and void and ould be
potentially dangerous. Repla ement parts should only be sour ed from Green Stove approved dealers
WARNING – FUME EMISSION
Properly installed and operated, this applian e will not emit fumes. O asional fumes from de-ashing and
refuelling may o ur. Persistent fume emission must not be tolerated.
If fume emission does persist, then the following immediate a tion should be taken: -
1. Open doors and windows to ventilate room
2. Let the fire out, or eje t and safely dispose of fuel from the applian e.
3. Che k for flue himney blo kage and lean if required.
4. Do not attempt to re-light the fire until the ause has been identified and orre ted.
If ne essary, seek professional advi e.
Imp rtant! – Do not fit an extra tor fan in the same room as this applian e.
IN THE EVENT OF A CHIMNEY FIRE
• Raise the alarm to let others in the house know.
• Call the Fire Brigade
• Redu e the applian e-burning rate by losing all air ontrols.
• Move furniture and rugs away from the firepla e and remove any nearby ornaments.
• Pla e a fireguard or spark guard in front of the stove.
• Feel the himneybreast for sign of ex essive heat.
If the wall is be oming hot, move the furniture away. Ensure that the Fire Brigade an gain a ess to your roof
spa e in order to he k this area for signs of fire spread.

Frequently Asked Questions
1 Do stoves require a himney?
All of our multi fuel and wood burning stoves require a suitable himney or professionally installed flue system.
2 How do I lean the himney?
You will require a himney sweep to lean the himney. It is best to provide a dedi ated himney leaning a ess door
when installing the flue of the stove.
3 Who should install my stove?
Green Stoves want you to enjoy the maximum performan e from your Stove produ ts. To ensure this, it is essential that
they are installed orre tly.
We strongly re ommend that your Green Stove is installed and regularly maintained by a qualified heating engineer.
4 How do I regulate the heat output?
Ea h stove will have spin valves, whi h will allow you to easily regulate the heat output.
5 What warranty poli y do I get?
Green Stoves will repla e, free of harge, any working
part that fails (under normal operating onditions) within 12 months
of pur hase. Consumables su h as glass or stove rope are not guaranteed.
A all out harge will apply if our engineer attends any stove problem that is not related to produ t failure.
6 Where an I get spare parts?
Your lo al Green Stove retailer will be pleased to supply spare parts and to provide any other information you require.
(Only use repla ement parts re ommended by the manufa turer).
7 Can the doors be left open while burning?
For safety and heat effi ien y the doors should remain losed at all times ex ept for ignition, de-ashing and loading the
firebox.
8 Why is the stove smoking when lit?
A smoking stove an be aused by a flue with ba k draught problems. A qualified fitter should omplete a smoke test prior
to fitting the stove to as ertain the integrity of the flue.
9 Why should I “Run in” my stove?
To begin, light a series of small fires over a period of a few days to allow the paint finish to ure. The stove is finish
ed with
a heat resistant paint and this an be leaned with a soft brush. Do not lean whilst the stove is hot; wait until it has ooled
down. The finish an be renovated with proprietary stove paint
If the stove is not “run in” orre tly, this may ause the paint to dis olour and flake.
10 What is Over Firing?
Your stove should never be used in a manner to ause over firing. Over firing an be aused by over loading the stove with
fuel, and with primary ontrols open. If any part of stove glows "red" your stove is over firing and your draught ontrol
should be adjusted to restri t airflow to stove. Over firing an ause permanent damage to the applian e whi h is not
overed by warranty.
