Installation instructions
The following pages give instructions for the safe and proper installation of this heating
appliance in the UK. These instructions cover the basic principles of installation, although
detail may need slight modification to suit particular local site conditions. In all cases the
installation must comply with current UK Building Regulations, Local Authority Byelaws
and other specifications or regulations as they affect the installation of the stove. 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 Reg-
istered Competent Persons can be found on their website at www.hetas.co.uk.
It should be noted that the current Building Regulations requirements are given in Ap-
proved Document J. These requirements may also be met by adopting the relevant recom-
mendations given in British Standards BS 8303 and BS EN 15287-1.
WARNING: Health and Safety Advice Notice
The installation of this heating appliance is governed by the Health and Safety at Work
Act 1974. It is the responsibility of the installer to ensure that all requirements of this Act
are met during the installation works. Attention is drawn in particular to the following:
Handling:
The appliance is a heavy item and adequate facilities must be available for loading,
unloading and site handling.
Fire Cement:
Some types of fire cement are caustic and should not be allowed to come into con-
tact with the skin. Protective gloves should be worn when handling fire cement. In
case of contact with the skin 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.
Important Warning –Preparatory Work and Safety Checks:
• This stove must not be installed into a chimney that serves any other heating appli-
ance.
• It’s recommendet not have an extractor fan fitted in the same room as the stove as
this can cause the stove to emit fumes into the room.
• If this appliance is installed into an existing chimney, the chimney must first be swept
and examined for soundness and suitability before the appliance is installed (see also
section headed “Chimney”).

Convection
RAIS stoves are convection stoves. This means that the stove’s back and side panels are
not over-heated. Convection means that there is a circulation of air, which ensures that
the heat is distributed more evenly throughout the entire room. The cold air is sucked in
at the base of the stove up through the convection channel, which runs along the stove’s
combustion chamber. The heated air pours out at the top of the stove, which ensures a
circulation of warm air throughout the room.
The stoves are equipped with a “cold” lever – RAIS special feature – which means you
could almost do away with gloves. Be aware, however, that all exterior surfaces become
hot during use - so take extreme care.
Chimney
The chimney is the driving force which makes the stove function. In order for the stove to
perform satisfactorily the chimney height must be sufficient to ensure the correct draught
of 14 to 18 Pa so as to clear the products of combustion and prevent problems of smoke
emanating into the room when firing.
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 calcula-
tion procedure given in BS 5854:1980 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 immedi-
ately 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 either a prefabricated block chimney in accordance
with Building Regulations Approved Document J or a twin walled insulated stainless steel
flue to BS 4543 can be used. These chimneys must be fitted in accordance with the manu-
facturer’s instructions and Building Regulations.

English RAIS - Manual for RAIS Rina, RAIS Viva
A single wall metal fluepipe is suitable for connecting the stove to the chimney but is not
suitable for using for the complete chimney. The chimney and connecting fluepipe must
have a minimum diameter of 150 mm and its dimension should be not less than the size
of the outlet socket of the stove which is 150 mm in diameter. 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 either an adjustable flue
damper or alternatively a draught stabiliser should be fitted. The adjustable flue damper
should not close off the flue entirely but should in its closed position leave a minimum
continuous opening free area of at least 20 % of the total cross sectional area of the flue
or fluepipe.
Adequate provision e.g. easily accessible soot door or doors must be provided for sweep-
ing the chimney and connecting fluepipe.
You should also familiarise yourself with the draught conditions for chimneys with 2 flues.
The flue outlet spigot is eiter 150 (6”) mm in diameter, or 129 (5”) mm in diameter.
For strong draughts, the chimney or flue should be fitted with a draught stabiliser. In
which case, it is important to ensure that there is a free flow-through area of minimum
20 cm² when the regulating gate is shut. Otherwise, the fuel energy may not be used
optimally. If, at any time, you are unsure about the condition of the chimney, you should
contact a chimney sweep.
Remember that access to the access door should be kept clear.
Installation
When installing the wood burning stove, there are some rules which MUST be followed:
The stove must be set up and installed in accordance with all current national and local
rules and regulations. Local authorities and a chimney specialist should be contacted prior
to set up.
It is prohibited to carry out unauthorised alterations to the stove.

9
English RAIS - Manual for RAIS Rina, RAIS Viva
There must be plenty of fresh air in the room where the stove is being installed, in order
to ensure proper combustion. Note that any mechanical exhaust ventilation - e.g. an
extraction hood - may reduce the air supply. Any air grates must be placed in such a man-
ner, that the air supply is not blocked.
The floor structure must be able to carry the weight of the wood burning stove, as well as
the weight of a chimney, if necessary.
When you choose where to set up your RAIS wood burning stove, you should consider
the heat distribution to the other rooms. This will enable you to get the best use out of
your stove.
The stove should be set up at a safe distance from inflammable materials.
See the manufacturer’s plate on the wood burning stove

Change of chimney connection
The stove is delivered ready for top outlet, but may be changed to back outlet in the fol-
lowing way:
Strike out the knock out plate at the rear of stove.
Remove the blanking plate and the packing, and
position them in the hovle at the top. Ensure that the
packing is positioned correctly. Screw all elements
together with the three M6 nuts.
Mount the flue collar, which is found in a bag in the
stove, and the clamp for the upper smoke conductor
with three M6x20 cylinder screws and M6 nuts.
Mount the parts in reverse order.

Installation distance in case of combustible wall
To find out whether the wall next to where the stove is going to be installed is flammable,
you should contact your building contractor or the local building authorities.
The hearth should be able to accommodate the weight of the stove. The chimney must
be independently supported by wall brackets or a ceiling support plate. The weight of the
stove is indicated in the brochure.
The stove should always be installed on a non-combustible hearth of a size and construc-
tion that is in accordance with the provisions of the current UK Building Regulations Ap-
proved Document J.
If the stove is to be installed on a wooden floor, it must be covered with a non-combusti-
ble material at least 12 mm thick, in accordance with UK Building Regulations Approved
Document J, to at distance of 300 mm in front of the stove and 150 mm to each side
measuring from the door of the combustion chamber.
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 UK Building Regulations Approved Document J and also in
these stove instructions.

For the Installer
Finally before firing the stove for the first time a check should be made to ensure that the
assembly and stove installation has been satisfactory and that there are no leaks in any
seals in the appliance and appliance connections to the chimney.
Ensure that the appliance and chimney flue are functioning correctly before finally hand-
ing over to the user. If necessary read the later parts of this manual for guidance on care
required when first lighting.
Inform the user that the appliance has been commissioned and ready to use and give
instruction on the safe operation of the stove.
These Instructions must be left with the user and the user should be instructed to keep
them in a safe place.

Operating instructions
Please note that HETAS Ltd Appliance Approval only covers the use of dry
seasoned wood logs on this appliance. HETAS Ltd Approval does not cover
the use of other fuels either alone or mixed with the wood logs, nor does it
cover instructions for the use of other fuels.
Fuel
The stove is designed and approved in accordance with EN 13240 and NS 3058 for stok-
ing split, dried firewood. The firewood must have a water content of 15-22% and its max.
length should be the length of the combustion chamber minus 50-60 mm.
Stoking with wet firewood causes both soot, environmental pollution and bad fuel
economy. Freshly cut wood contains approx. 50-70% water and is thoroughly unsuitable
for stoking. Count min. 1 year of storage time for newly cut wood before using.
Wood with a diameter of more than 100 mm should be split. Regardless of wood size, it
should always have at least one surface area free of bark.
We do not recommend stoking with painted, laminated or impregnated wood, wood with
a synthetic surface, painted refuse wood, chipboard, plywood, domestic waste, paper bri-
quettes and pit coal, as this will produce malodorous smoke, which could be poisonous.
When firing with the above-mentioned items and amounts larger than those recommend-
ed, the stove is subjected to a larger amount of heat, which results in a higher chimney
temperature and lower efficiency. This can result in the stove and chimney becoming dam-
aged and would void the warranty.
The calorific value of the firewood is closely connected to the moisture level of the
firewood. Moist firewood has a low heat value. The more water the wood contains, the
more energy it takes for this water to vaporise, resulting in this energy being lost.
ONLY USE RECOMMENDED FUELS
The following table shows the calorific value of different types of wood, which have been
stored for 2 years, and which have a residual moisture of 15-17%.
Wood Kg dry wood pr. m3 compared to beech/oak
Hornbeam 640 110%
Beech and oak 580 100%
Ash 570 98%
Maple 540 93%
Birch 510 88%
Mountain pine 480 83%
Fir 390 67%
Poplar 380 65%
1 kg of wood yields the same heat energy irrespective of wood type. 1 kg beech merely
takes up less space than 1 kg of fir.
