Installation Instructions
READ THESE INSTRUCTIONS CAREFULLY BEFORE INSTALLATION
These instructions cover the basic principles to ensure satisfactory installation of the stove, although
detail may need slight modification to suit particular local site conditions. In all cases the installation
must comply with National and European Building Regulations, Local Authority Byelaws and other
specifications or regulations as they affect the installation of the stove.
It should be noted that the Building Regulations requirements may be met by adopting the relevant
recommendations given in British StandardsBS 8303, BS EN 15287-1:2007 as an alternative means
to achieve an equivalent level of performance to that obtained following the guidance given in
Approved Document J.
Please note that it is a legal requirement under England and Wales Building Regulations that the
installation of the stove is either carried out under Local Authority Building Control approval or is
installed by a Competent Person registered with a Government approved Competent Persons
Scheme. HETAS Ltd operate such a Scheme and a listing of their Registered Competent Persons can
be found on their website at www.hetas.co.uk.
Health and Safety Precautions
Handling
Adequate facilities must be available for unloading and site handling.
Fire Cement
Some types of fire cement are caustic and should not be allowed to come into contact
with the skin. In case of contact, wash immediately with plenty of water.
Asbestos
This stove contains no asbestos. If there is a possibility of disturbing any asbestos in the
course of installation then please seek specialist guidance and use appropriate protective
equipment.
Metal Parts
When installing or servicing this stove, care should be taken to avoid the possibility of
personal injury.
Please note:
Any white deposits on the stove joints are caused by humidity reacting with the joint
sealant. These deposits may be brushed off and, if necessary, blackened with a
proprietary stove polish.
Important Warning
This stove must not be installed into a chimney that serves any other heating appliance.

Chimney
In order for the stove to perform satisfactorily the chimney height must be sufficient to
ensure an adequate draught of between 12 Pa and 25 Pa so as to clear the products of
combustion and prevent smoke problems into the room.
NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet
of the stove to the top of the chimney should be satisfactory. Alternatively the calculation
procedure given in EN 13384-1 may be used as the basis for deciding whether a
particular chimney design will provide sufficient draught.
The outlet from the chimney should be above the roof of the building in accordance with
the provisions of Building Regulations Approved Document J.
If installation is into an existing chimney then it must be sound and have no cracks or
other faults which might allow fumes into the house. Older properties, especially, may
have chimney faults or the cross section may be too large i.e. more than 230 mm x 230
mm. Remedial action should be taken, if required, seeking expert advice, if necessary. If
it is found necessary to line the chimney then a flue liner suitable for solid fuel must be
used in accordance with Building Regulations Approved Document J.
Any existing chimney must be clear of obstruction and have been swept clean
immediately before installation of the stove. 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 between the stove and the
open fire.
If there is no existing chimney then any new system must be to the designation described
above and in accordance with Building Regulations Approved Document J.
A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not
suitable for use as the complete chimney. The chimney and connecting fluepipe must
have a minimum diameter of 150 mm and its dimension should at no point be less than
the size of the outlet socket of the stove.
Any bend in the chimney or connecting fluepipe should not exceed 45. 90bends should
not be used.
Combustible material should not be located where the heat dissipating through the walls
of fireplaces or flues could ignite it. Therefore when installing the stove in the presence
of combustible materials due account must be taken of the guidance on the separation of
combustible material given in Building Regulations Approved Document J and also in
these stove instructions.
If it is found that there is excessive draught in the chimney then a draught stabiliser
should be fitted.

Adequate provision e.g. easily accessible soot door or doors must be provided for
sweeping the chimney and connecting fluepipe.
Hearth
The hearth should be able to accommodate the weight of the stove and its chimney if the
chimney is not independently supported. The weight of the stove is indicated in the
brochure.
The stove should preferably be installed on a non-combustible hearth of a size and
construction that is in accordance with the provisions of the current Building Regulations
Approved Document J.
The clearance distances to combustible material beneath, surrounding or upon the hearth
and walls adjacent to the hearth should comply with the guidance on the separation of
combustible material given in Building Regulations Approved Document J and also in
these stove instructions.
If the stove is to be installed on a combustible floor surface, it must be covered with a
non-combustible material at least 12mm thick, in accordance with Building Regulations
Approved Document J, to a distance of 30 cm in front of the stove and 15 cm to each side
measuring from the door of the combustion chamber.
Combustion air supply
In order for the stove to perform efficiently and safely there must be an adequate air
supply into the room in which the stove is installed to provide combustion air. The
provision of air supply to the stove must be in accordance with current Building
Regulations Approved Document J. An opening window is not appropriate for this
purpose. If it was necessary to fit a draught stabilizer due to excessive chimney draught
then attention must be paid to the permanent combustion air requirements as this will be
different as detailed in Approved Document J.
Connection to chimney
All the stoves have a choice of either rear or top flue gas connector that allows
connection to either a masonry chimney or a prefabricated factory made insulated metal
chimney in accordance with the instructions. It may be necessary to fit an adaptor to
increase the diameter of the flue to the required 150 mm section of the chimney or liner.

Material Clearances
The stove can be recessed in a suitable sized fireplace but a permanent free air gap of at
least 150mm 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.
All non-combustible walls closer than 400mm to the stove should be at least 75mm thick.
In all instances the back wall of the fireplace recess and the hearth should be made of
non-combustible material. Allow an apron of at least 300mm at the front of the stove and
150mm on either side. The hearth on which the stove is to be placed should not be less
than 125mm thick and should be in accordance with the current building regulations.
Care should be taken to level the stove using the adjusting screws in the feet.
The appliance shall be installed on a floor with adequate load-bearing capacity. If the
existing construction does not meet this prerequisite, suitable measures (e.g. load
disturbing plate) should be taken to achieve it.

Commissioning and Handover
Upon completion of the installation, allow a suitable period of time for any fire cement
and mortar to dry out. A small fire may then be lit and checked to ensure the smoke and
fumes are taken from the stove up the chimney and emitted safely to atmosphere. Do not
run the stove at full output for at least 3 –4 days.
On completion of the installation and commissioning, ensure that the operating
instructions and operating tools for the stove are left with the customer. Ensure to advise
the customer on the correct use of the appliance with the fuels likely to be used on the
stove and warn them to use only the recommended 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 presence of children, aged and/or infirm persons.

Operating Instructions
This appliance is not suitable for use in a shared flue.
This appliance should not be operated with the doors open.
This appliance is capable of intermittent operation.
Aerosol Sprays
Do not use an aerosol spray on or near the stove when it is alight.
Air Controls
This stove has been designed to burn clean and efficient. If used correctly this stove will
burn far more efficiently than normal with the obvious notable features of CLEAN
GLASS. Never clean glass when stove is hot. Always use stove glass cleaner which is
available from your stove retailer.
However, for this product to work properly it must be used correctly.
It is essential that the stove has an adequate air supply for combustion and ventilation.
The primary and secondary air inlets must be kept clear from obstruction.
Warning! This appliance will be hot when
In operation and due care should be taken
When operating the controls.
Air Controls
Primary Air
Primary air is controlled via the two rotary air controls on the bottom of the door.
This provides a conventional air draught to the bed of the fire. The primary air intakes
can be adjusted to give the best possible results when burning different fuels.
Secondary Air
The cast iron stove is fitted with an “air wash” system. This secondary air supply to the
stove is controlled through a rotary control assembly located at the top of the stove, above
the door.
Grate
Your Green Stove is fitted with a rotary style grate, which 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 located in the centre of a cast 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 can damage the cast
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.
Notes on Wood burning
With a full load of wood, the stove will need to be refuelled approximately every 1.5
hours. Wood can be stacked higher in the stove than solid mineral fuel but care must be
taken that logs do not touch the baffle.
Wood burns most efficiently with the primary air controls closed and the secondary
control partially open. Moving the secondary control will control the burn rate of the
stove.
Note –primary and secondary air is needed to light the stove, see section entitled
„Lighting the Stove‟.
Wood burns best on a bed of ash and it is therefore only necessary to remove surplus ash
from the stove occasionally.
Burn only dry, well-seasoned wood, which should have been cut, split and stacked for at
least 12 months, with free air movement around the sides of the stack to enable it to dry
out. Burning wet or unseasoned wood will create tar deposits in the stove and chimney
and will not produce a satisfactory heat output. Do not use liquid fuels in this appliance.
Lighting the Stove
We recommend 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 cure in steadily and to give a long
service life of the paint finish. During this curing in process you may notice an unpleasant
smell. It is non-toxic, but for your comfort 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 sticks and/or firelighters in the mode
chosen, either wood or solid mineral fuel.
Light the fire at the base leaving all air controls open. Allow the fuel to reach a steady
glow and build the fire up gradually. Once you have a good fire established across the
grate bed, further fuel can be added as required.
Shutting Down
In order to shut down the stove, close the primary air controls, then close the secondary
air rotary control by moving the handle all the way to the left. If the controls 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 recommended that the primary air controls are open first, then open the secondary air
rotary control.
Warning! - The stove will remain hot for a considerable time after the fire has been
extinguished.
Notes:
Warning! - Petroleum coke fuels, household waste or liquid fuels must not be burnt on
this appliance.
Should any difficulties arise over fuel quality or suitability, consult your local approved
coal merchant.
Chimney cleaning
The chimney should be swept at least twice a year. It is important that the flue connection
and chimney are swept prior to lighting up after a prolonged shutdown period.
If the stove is fitted in place of an open fire then the chimney will require sweeping after a
month of continuous operation. This is a precaution to ensure that any “softer” deposits left
from the open fire usage have not been loosened by the higher flue temperatures generated
by the closed stove.
In situations where it is not possible to sweep through the stove the installer will have
provided alternative means, such as a soot door. After sweeping the chimney the stove
flue outlet and the flue pipe connecting the stove to the chimney must be cleaned with a
flue brush.
Periods of Prolonged Non-Use
If the stove is to be left unused for a prolonged period of time then it should be given a
thorough clean to remove ash and unburned fuel residues. To enable a good flow of air
through the appliance to reduce condensation and subsequent damage, leave the air
controls fully open.
Safety Notes for your guidance
FIRES CAN BE DANGEROUS –Always use a fireguard in the presence of children,
the elderly or the infirm.
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 fire 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.

Any unauthorised modifications of this appliance will render the guarantee null and void
and could be potentially dangerous. Replacement parts should only be sourced from
Green Stove approved dealers
WARNING –FUME EMISSION
Properly installed and operated, this appliance will not emit fumes. Occasional fumes
from de-ashing and refuelling may occur. Persistent fume emission must not be tolerated.
If fume emission does persist, then 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 appliance.
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! –Do not fit an extractor fan in the same room as this appliance.
IN THE EVENT OF A CHIMNEY FIRE
Raise the alarm to let others in the house know.
Call the Fire Brigade
Reduce the appliance-burning rate by closing all air controls.
Move furniture and rugs away from the fireplace and remove any nearby
ornaments.
Place a fireguard or spark guard in front of the stove.
Feel the chimneybreast for sign of excessive heat.
If the wall is becoming hot, move the furniture away. Ensure that the Fire Brigade can
gain access to your roof space in order to check this area for signs of fire spread.

Frequently Asked Questions
1 Do stoves require a chimney?
All of our multi fuel and wood burning stoves require a suitable chimney or
professionally installed flue system.
2 How do I clean the chimney?
You will require a chimney sweep to clean the chimney. It is best to provide a dedicated
chimney cleaning access door when installing the flue of the stove.
3 Who should install my stove?
Green Stoves want you to enjoy the maximum performance from your Stove products. To
ensure this, it is essential that they are installed correctly.
We strongly recommend that your Green Stove is installed and regularly maintained by a
qualified heating engineer.
4 How do I regulate the heat output?
Each stove will have spin valves, which will allow you to easily regulate the heat output.
5 What warranty policy do I get?
Green Stoves will replace, free of charge, any working part that fails (under normal
operating conditions) within 12 months of purchase. Consumables such as glass or stove
rope are not guaranteed.
A call out charge will apply if our engineer attends any stove problem that is not
related to product failure.
6 Where can I get spare parts?
Your local Green Stove retailer will be pleased to supply spare parts and to provide any

other information you require. (Only use replacement parts recommended by the
manufacturer).
7 Can the doors be left open while burning?
For safety and heat efficiency the doors should remain closed at all times except for
ignition, de-ashing and loading the firebox.
8 Why is the stove smoking when lit?
A smoking stove can be caused by a flue with back draught problems. A qualified fitter
should complete a smoke test prior to fitting the stove to ascertain 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 cure. The stove is finished with a heat resistant paint and this can be cleaned with a
soft brush. Do not clean whilst the stove is hot; wait until it has cooled down. The finish
can be renovated with proprietary stove paint
If the stove is not “run in” correctly, this may cause the paint to discolour and flake.
10 What is Over Firing?
Your stove should never be used in a manner to cause over firing. Over firing can be
caused by over loading the stove with fuel, and with primary controls open. If any part of
stove glows "red" your stove is over firing and your draught control should be adjusted to
restrict airflow to stove. Over firing can cause permanent damage to the appliance which
is not covered by warranty.
